    A new lease of life for your machine

    45,000 operating hours. This is how long - or even longer - a 15-year old cylindrical grinding machine is in use. Anything that does this much will wear, and this particularly shows itself in the geometry and precision. High time to give the machine a good overhaul. A machine overhaul at STUDER makes an old machine into one that is as good as new; in other words, a machine that has the same tolerances as when it was first delivered. If the requirements on the machine have also changed, the machine can be configured and retrofitted to the customer's requirements during the overhaul.

    The S40 was in use at LMT Kieninger for 14 years. The company specializes in highly demanding machining tasks and manufactures special tools for die and mold making. "The S40 was the Rolls Royce of grinding machines. But the machine still wears over time and after intensive use", admits Heiko Braun, Group Manager of Cylindrical/Surface Grinding and Assembly. It was clear to LMT Kieninger that they should send the cylindrical grinding machine to the STUDER factory in Switzerland for an overhaul. STUDER provided them with a loan machine for around three months and took care of everything from A to Z - from collection through to customs formalities. "We were very satisfied with the loan machine. Apart from a few little things, we were able to continue grinding as usual", sums up Braun. The special feature about a machine overhaul at STUDER? It is the only company to refurbish the machines' guideways to the original specifications. After the assemblies have been reinstalled, the machine geometry is equivalent to that of a new machine. Braun's view: « This point in particular really convinced us. We notice the difference. Since the overhaul we have been grinding with the precision of a new machine. I can only recommend a machine overhaul. Everything went without a hitch, the investment has paid off and a 1600 mm machine is worth its weight in gold for us. »

    Rebuild – new from old
    A rebuild, or a machine overhaul, makes sense, and not just economically. The operator gets his familiar machine back and continues where he stopped before the overhaul. But he is full of enthusiasm! Because his old machine is like new. In the STUDER factory the specialists disassemble the machine into all its individual parts. The guideways are completely refurbished, the assemblies overhauled, the wear parts in the electric cabinet replaced, hydraulic and lubricating system as well as all valves replaced. If old spare parts can no longer be obtained, STUDER provides an alternative solution. The casing and components are sand-blasted and then given a fresh coat of paint. After assembly the geometry is like that of a new machine. Commissioning is carried out by STUDER Customer Care, including a functional and geometry inspection, all CE-compliant. "Over 20 people work on machine overhauls at STUDER. This shows the value of rebuild and retrofit at STUDER. The customers are always enthusiastic about the transformation and are delighted to put an as-new machine into operation at an excellent price-performance ratio", says Marcos Cotarelo, Divisional Head and Customer Care Consultant.

    Expanding the component range
    If the customer wishes to expand his component range at the same time as the overhaul, he does this with a retrofit. During the machine overhaul the machine can be modified or retrofitted to the customer's requirements. This opens up new production possibilities on the same machine. Ingold Tools AG has taken advantage of this STUDER service.

    Ingold Tools AG has been producing high-precision and complex parts for spindle, compressor, hydraulic and general machine manufacturing with 25 employees since 1946. The machinery includes a variety of CNC-controlled and conventional machines, including robot-automation solutions for turning, milling/drilling, honing, lapping, barrel finishing, sand-blasting, laser marking as well as surface and cylindrical grinding. The cylindrical grinding shop already has several conventional and CNC STUDER machines. A further machine is currently being overhauled in the STUDER production halls. This is an 18-year old S21 with two external spindles and continuous fine adjustment of the turret wheelhead (B-axis fine), which the two managing directors Christoph Jenzer and Edgar Stich recently took on as a second-hand machine. The S21 will not only be updated in line with the latest developments, but will also be retrofitted to suit the needs of Ingold Tools AG. The cylindrical grinding machine will have an additional internal grinding spindle for internal cylindrical grinding and the relevant fixture for swiveling the tailstock into the park position. The S21 will also have a new spindle cooling system with its own circuit, as well as a hydraulically swiveling dressing unit. So that all grinding machines have the same mounting, the universal tool headstock will also be upgraded from MK4 to MK5. "This deal is perfect for us. Thanks to the retrofit, we get the second-hand machine with 50 percent new hardware", enthuses Jenzer.

    Trusted quality
    The S21 is the second factory-rebuilt STUDER machine at Ingold Tools AG. In 2016 the company took on a second-hand S31 machine, which STUDER overhauled. "We grind to a bearing tolerance and diameter of 1my. STUDER guarantees this accuracy after the overhaul. Either way: An overhauled STUDER will run just as long as a new machine", attests Stich. Jenzer and Stich see a further advantage of the machine overhaul in the operation: "The employees don't have to get used to a new machine with a new control system."

    Ingold Tools has relied on STUDER since it was established in 1946. The first external cylindrical grinding machine was a type 01 from the year 1955. This was still in use when Christoph Jenzer joined the company 13 years ago. "We like working with STUDER. The service personnel are quick to respond, and our Customer Care Consultant supports us wherever he can. It's not without reason that we have so many STUDER machines." A new machine? Jenzer and Stich say: "We wouldn't rule it out – a new machine always offers advantages which an old one doesn't have, such as faster travel in all axes, simpler set-up of the machine, and easy programming with less technical knowledge." But the employees are looking forward to the overhauled S21, which will soon be on its way to Inkwil in Bern.

    STUDER - Your 360 ° solution for internal grinding

    It was in 1933 when the first internal cylindrical grinder type 01 was delivered from Fritz Studer AG. 85 years later, STUDER presents with a product range of 12 machines probably the largest portfolio in the world for internal cylindrical grinding.

    Kptec Components GmbH from Schorndorf (Germany) is a component manufacturer for the machine tool industry. The focus is on spindles, rotors, spindle casings, connecting rods and flange parts. The core competence is grinding. Walter Wiedenhöfer, Managing Director of Kptec Components, explains that consistently achieving tolerences in the micron range (40mill") in production is the great challenge in grinding." In the production of spindle components, coaxilities under one micron (40mill") are state-of-the-art. It is often necessary to grind an H6 fit into bores up to 400 mm (15.7") deep for the clamping interface mechanism. In addition, the machine should manufacture as economically as possible. In other words: You should only handle the component once and then completely finish it in one step. But a good machine should also flexible to enable it to handle uncommon operations such as the grinding of slots in a spindle too. One machine that meets such requirements is the universal internal cylindrical grinding machine S151. Fully equipped, it has three internal and one external grinding spindle, as well as a measuring probe. It convinced Kptec. Today Wiedenhöfer says: « The machine is the best we have in the company – it was absolutely the right decision to buy a STUDER machine. »

    The Universal
    STUDER has the right machine for every demand in internal grinding. In the universal range, these are the S121, S131, S141 and the S151. The inexpensive universal S121 is the ideal machine for internal, face and external grinding of chuck components. The S131, S141 and S151 form a product range for every imaginable application in internal cylindrical grinding. They are used where very high precision and efficiency are required – for example, flange parts, spindle shafts, spindle housings, rotor shafts, bushings and much more. The maximum workpiece weight is 250kg (550lbs) and the maximum workpiece length is 1300mm (51.2").

    For production
    The S110 is a very flexible and compact internal cylindrical grinding machine ideal for chuck applications for indivudual parts or small series production. Thanks to its small footprint it will fit in any workshop. S122 specializes in small bores and is equipped with a swing diameter of 220 mm. It offers state-of-the-art technology for the processing of small to medium-sized workpieces in small to large-scale production. Both types can handle up to three grinding spindles in a parallel arrangement, which allows for external and internal grinding in one clamping. "Price, quality, technical standard – that was our selection criteria for a new machine. The biggest advantage is the high production capacity", says Miroslav Martinek, Production Manager at Sellier & Bellot, explaining his investment decision in an S110.

    Three sizes for radii
    The S121, S131 and S141 are the experts for high-precision internal cylindrical grinding of radii, spheres, cones and diameters. The maximum swing diameter is 400mm (25.6") and the maximum workpiece weight is 100kg (220lbs). The main areas of application are in the production of drawing dies made of tungsten carbide and ceramics and the production of hydraulic components such as axial pump pistons, guide plates, housings made of hardened steel, grey cast iron and copper. Complex workpieces made of industrial ceramics, sapphire and tungsten carbide for the manufacture of human implants are also within the scope of applications. The automatic B-axis with direct drive allows grinding with interpolation for the high-precision machining of radii. The Radius grinding machines are supported by the Software StuderSIM. A S131 – with an option for radius grinding – is installed at AKS Hartmetalltechnik GmbH in Schwbisch Gmünd. "The sophisticated CNC technology of combining various operations in a single clamping and thus acheiving maximum precision These criteria convinced us. The set-up times, maintenance costs and downtime are now calculable. We also benefit from the rapid response times of STUDER Customer Care", explains
    Production Manager Edgar Feifel.

    Solid design
    The internal cylindrical grinding machines are based on the Granitan® machine bed with its excellent damping proprieties and the StuderGuide® guideway system. Its huge advantage over hydrostatic guideways is the damping component in the direction of movement. The dressing process can be flexibly and optimally adapted to the workpiece, tool and material-specific properties - according to the customer's wishes. Another Studer speciality are the grinding wheel reference points (T numbers). This enables programming with normal dimensions, which considerably simplifies the programming of grinding programs. The workhead can be moved on the swiveling B-axis in the longitudinal direction, has a high roundness accuracy and is low in maintenance. An air cushion lift-off facilitates simple movement during setup and resetting.

    Sophisticated sensor technology monitors the process of grinding and dressing and provides an easy detection the grinding wheel and workpiece position. The contact detection serves the purpose of cycle-time reduction. The modular spindle concept enables optimal adaptation to the grinding task. The direct drive in the grinding spindle turret head guaranties the smallest positioning variation for the radius and universal grinding machines (except S110 / S122). In the S122, the efficient high-precision processing of small diameters is also possible due to the proven grinding arbor deflection compensation.

    Loading systems are available for automation that, due to their modular design, can be adapted exactly to the machine application and process. The appropriate periphery ensures seamless integration into the production process.

    Everybody a grinding expert
    For the operation of the machine, it is no longer necessary to be a grinding expert. All you have to do is know is the specifications of the part and what the surface finish should be at the end of the process. StuderTechnology recommends the optimal grinding parameters and generates the program. StuderWIN offers the possibility to fully integrate the measuring control and also sensor technology for process monitoring, such as contact detection and balancing systems, into the user interface. This allows uniform programming of the different systems. StuderWIN is supplemented by the grinding software StuderPictogramming. The operator lines up the individual grinding cycles together - the control generates the ISO code. The functionality of the machine is increased with the Software option for form and thread grinding. The StuderSIM software was specifically developed for the internal grinding of radii. Das Betriebssystem ermöglicht das Programmieren von allen Basiszyklen für das Schleifen, Abrichten und prozessunterstützende Messen. This way of programming guarantees great flexibility with the highest user experience. After programming, the process can be simulated and optimized. This gives reliability and guarantees short programming times and consequently an increase in profitability.

    Conclusion
    There is hardly a workpiece that cannot be processed with the STUDER internal grinding machines. The Swiss grinding machine manufacturer offers the right machine for every imaginable application. Very pleasant for the operator is the optimal ergonomics, which further increases the relative value of the machines.

    Flexibility founded on ergonomics.

    Date: 

    With the introduction of the S131 and S151 universal internal cylindrical grinding machines, STUDER has now expanded the successfully established S141 into a complete series. The S131, S141 and S151 represent a brand new series of internal cylindrical grinding machines, in which STUDER has paid special attention to the customer advantages of ergonomics, handling and flexibility. The S131 has a swing diameter over the table of 250 mm and enables a maximum grinding length of 160 mm for internal and 125 mm for external diameters. It is available in one design length for workpieces with a maximum length of 300 mm. The S141 is available in different models for workpieces with maximum lengths of 300, 700 and 1300 mm. The swing diameter over the table is 400 mm for all models, while the maximum grinding length is 250 mm for internal and 150 mm for external diameters. The S151 is slightly larger than the S141, with a swing diameter over the table of 550 mm and a maximum grinding length of 390 mm for internal and 150 mm for external diameters. The user can choose between two models for maximum workpiece lengths of 700 and 1300 mm. Even a first glance at the S131, S141 and S151 clearly shows the sophisticated ergonomic concept of the series. The ergonomic design ensures safety during machine operation and workpiece inspection, as well as efficient process control. Above all, the ergonomic design of the machines also contributes to the operator's well-being in the long term. The features responsible for these advantages include, the axis layout of the machines and the arrangement of the spindles at the front of the spindle turret, the new dressing concept and the generously dimensioned 2-leaf sliding doors, which not only enable good accessibility for workpiece and grinding wheel change but also exceptional visibility.

    Minimized to the max.

    Date: 

    The S121 from STUDER is a universal internal cylindrical grinding machine for medium-sized workpieces in individual and small batch production. Equipped with the advanced technology of its sister machines S131, S141 and S151, this series model has been limited to the essential equipment. A striking example is the spindle turret, which swivels through 180° to a stop and is equipped with two grinding spindles. Alternatively a fixed spindle is possible. With the S121 STUDER has thus created a tailor-made machine for internal, surface and external grinding of chuck components, which offers exceptional value for money. While a T-slide arrangement or the use of maximum two tools guarantees the attractive price, the manufacturer has made no compromises in terms of the advanced technologies used. This is evident in the StuderGuide® guideway system for the X- and Z-axis, which guarantees high geometrical traversing and guidance accuracy through the entire speed range, together with high load capacity and cushioning levels. At the same time the combination of StuderGuide®, linear motors and direct measuring systems guarantee exceptional interpolation accuracies. Although the smallest machine in the universal series in terms of space requirement, larger diameters can be machined on the S121 than on an S131. This makes it a high-performance machine with an impressively compact design and excellent ergonomics. STUDER's offering of high performance in a small footprint with the customized S121 is evident in the swing diameter over the table of 400 mm and the maximum workpiece length of 300 mm, with a maximum grinding length of 175 mm for internal and 100 mm for external diameters. This large range of workpiece dimensions is made possible by optimal arrangement of the machine components.

    The experts in internal and radius grinding.

    Date: 

    With regular new developments every six months, Fritz Studer AG has surprised users of internal cylindrical grinding machines in the last two years. What still appeared as a separate machine with the S141 universal machine (component length up to 1300 mm) in May 2014 has evolved into a complete machine platform with the universal machines in the S141 and S151 series in autumn 2014, the S131 universal machine and the S122 production machine in spring 2015 as well as the S121 universal machine in autumn 2015. STUDER is now completing this platform with a final coup: The Thun grinding machine specialist is bringing three new radius internal cylindrical grinding machines to market, to replace the successful CT700 and CT900 models. The main fields of application of the new S121, S131 and S141 radius grinding machines are the manufacture of dies – especially in the packaging industry –, where tungsten carbide and ceramic are primarily processed, and the production of hydraulic components such as axial pump pistons, guide plates and housings made of hardened steel, cast iron and copper. Other fields are the production of complex workpieces with several tapers greater than 20° to 90° in a single clamping, where the main applications are in watch and medical technology with extra-hard materials such as industrial ceramic, sapphire and tungsten carbide, as well as the manufacture of human implants for shoulders, knees and hips from ceramic and titanium.

    The highly productive machine for small bores.

    Date: 

    Manufacturing companies cannot cut corners in production processes which are optimized down to the smallest detail. The focus is on the process. In order to produce a component in a specified time and quality, each part of the process must have the optimum solution. STUDER provides this solution: The S122 from STUDER is a production internal cylindrical grinding machine for the production of small to medium-sized workpieces in small and large-scale production. When a company purchases this machine, it also purchases productivity. With a swing diameter of 220 mm, this production grinding machine can machine workpieces up to 120 mm in length. The maximum grinding length is 110 mm for internal and 40 mm for external diameters. A large output of parts with short grinding, auxiliary and loading times is just as important for productivity in production as high machine availability and a high level of process reliability. The S122 offers all of these characteristics. Short grinding times are ensured by the grinding technology and the grinding know-how of the Internal Grinding Competence Center. The axis concept and the parallel spindle arrangement, in which up to three spindles can be used, are responsible for short auxiliary times. Short loading times are ensured by the fully integrated loader. Different loading systems are available for the S122, which can be precisely adapted to the machine application and the machining processes thanks to their modular design. The integrated loader stands out in terms of its favorable price. In addition, complex systems with pre- and post-process stations, automatic correction, measured value recording and evaluation can also be easily implemented on the S122.

    Perfect internal grinding.

    Date: 

    With the S141 STUDER introduced another trend-setting cylindrical grinding machine to the market in 2014. Its technical features and true STUDER precision are extremely impressive. No matter whether its a flange component that is required or spindles up to 1300 mm, the S141 CNC Universal internal cylindrical grinding machine can meet any challenge. The machine's ergonomic design and user friendliness are evident at first glance. Two generously-sized sliding doors provide the best accessibility not only to the workpiece but also when changing the grinding wheel. Short changeover times and fast reprogramming of the controls help keep downtime to a minimum. This makes the machine very interesting for the production of single pieces, small and large series. The S141 is available in a variety of model lengths for workpieces up to maximum lengths of 300, 700 and 1300 mm (11.8”, 27.5” and 51.1”). In all models, the swing diameter over the table is Ø 400 mm (15.7”) and the maximum grinding length is 250 mm (9.8”) for internal and 150 mm (5.9”) for external grinding. The S141 is the ideal machine for grinding spindle shafts, spindle casings, rotor shafts, axes or flange parts. STUDER is now advancing work on the S141, which has been successfully launched on the market, to produce its S131 and S151 machines and thus introduce an entire series. The S131 is much smaller and more compact than the S141 - with a swing diameter over the table of Ø 250 mm (9.8”) and a maximum grinding length of 175 mm (6.9”) for internal and 125 mm (4.9”) for external grinding. It is available for workpieces with a maximum length of 300 mm (11.8”). The S151 is a somewhat larger than the S141 - it has a swing diameter over the table of
    Ø 550 (21.6”) mm and a maximum grinding length of 400 mm (15.7”) for internal and
    150 mm (5.9”) for external grinding. It is available for workpieces with a maximum length of 700 mm (27.5”).
    Naturally, the S131 and S151 machines are designed using the same fully developed technology as the S141. In the design of the S141 particular focus was placed on ergonomics.

    STUDER WireDress® - New technology for dressing metal-bonded grinding wheels.

    Date: 

    The integrated electro-discharge dressing technology WireDress® opens up brand new possibilities for grinding with metal-bonded grinding wheels and drastically cuts auxiliary times. Metal-bonded grinding wheels are used to machine difficult-to-machine materials such as high-alloy, hardened steels, tungsten carbides and ceramics, as they are offer superior dimensional and thermal stability. However, there are also disadvantages in using metal-bonded grinding wheels. Dressing these wheels involves greater expense and effort. External dressing machines are sometimes used for dressing, creating huge demands on handling and logistics. With WireDress® STUDER brings a brand new dressing device to the market, which is completely integrated into the cylindrical grinding machine and its control system. Laborious dismounting and resetting of the grinding wheel for wheel dressing is no longer necessary. The dressing device is a small wire erosion machine in principle. The electrode is a wire. The STUDER-WireDress® control unit is integrated into the control system of the cylindrical grinding machine. The machine operator does not need any special training to operate the dressing device. He is guided by the clear and transparent guidelines on the screen of the control unit.

    BluePlus – STUDER helps its customers to use resources more efficiently.

    Date: 

    As global energy requirements are constantly increasing, it is imperative that the available energy is used more efficiently and effectively. Like all other companies in the UNITED GRINDING Group, STUDER qualified for the «Bluecompetence» label of the Verband Deutscher Maschinen und Anlagebau e.V. (VDMA - German Engineering Federation) a number of years ago. The label is designed to establish energy-saving and resource-efficient products, technologies and processes. Fritz Studer AG has gone a step further and created its own BluePlus label. Under this label, STUDER has developed the concept of the 4 BlueSteps. The aim is to develop and apply technologies, which save energy and costs in the construction and use of STUDER cylindrical grinding machines. The 4 BlueSteps concept comprises the following steps: Step1: Optimal component selection and dimensioning of the machine. Step2: Standby management optimized to customer requirements. Step3: "StuderTechnology" software. This helps to bring the machine operator closer to an optimized grinding process straight away and thus saves optimization costs, increases productivity and reduces the energy costs per workpiece. Step4: EE4C – a concept, which has been developed in collaboration with the Swiss Federal Institute of Technology in Zurich/Inspire, to enable the optimal design of a machine's configuration with regard to the energy consumed for each produced workpiece. Examples, which show the specific measures taken by STUDER to make its cylindrical grinding machines more energy efficient:
    • Granitan®
      Requires less than 40% of the energy needed for a comparable iron cast bed.
    • StuderTechnology
      Immediately optimizes finishing processes even more and reduces processing times by 50%.
    • StuderGRIND / StuderWIN
      Down-times and spoilage can be avoided. Energy and raw material requirements are also reduced.
    • Machine components
      More energy efficient equipment in the coolant and extraction system.
