Studer cylindrical grinder is modular
1 min read
Following the introduction of the S12 and the S242, Studer has followed up with the modular S22.
The S22 production platform can be tailored to satisfy specific user requirements. In the case of components such as workhead and wheelhead or tailstock, all parts that Studer has ever developed and produced are available on the S22.
The platform also has no fixed distance between centres, this being anywhere between 650 and 1100 mm.
The S22 is suitable for universal cylindrical grinding in the production environment, high speed grinding (HSG) or heavy duty applications.
StuderWIN, Studer's new Windows based operator interface, features, and it offers many new advantages. The S22 is equipped with a Fanuc 310i-A CNC control with integrated PC".
All S22 versions have the proven GRANITAN machine bed with its excellent damping characteristics and thermal stability. The X and Z axes are designed as a cross-slide, while the workpiece table is bolted permanently to the machine.
Two different axes drive systems are available, the X-axis is equipped with roller guideways as standard, and the Z-axis has a guideway with patented surface structure. Drive is via ballscrews.
For the highest dynamics and precision, Studer offers an alternative with direct drive and friction-free guideways in both axes. The hydrostatics and linear motors (pictured) allow axis movements up to 30 m/min, while precision to a 0.0001 mm is achieved, with the measuring system having a resolution of 0.00001mm.
Available are chuck or universal workhead, standard or high-precision C-axis (position and speed controlled for form and thread grinding), belt or motor spindle wheelhead, standard, synchronous or fine grinding tailstock, dressing from the rear with a wide variety of devices etc - a broad selection meets every possible requirement.
An integrated measuring system for measuring during the grinding process, for re-measuring, recording, evaluation and correction guarantees comprehensive quality control.
For high-speed grinding there is a B-axis with two grinding spindles in versions left/left or right/left for 400 mm wheels in the cutting speed range between 80 and 140 m/s. Heavy-duty applications with a 160 mm wide grinding wheel are also possible.
A large range of loading and unloading systems is offered. The machine can be loaded on both sides, or from above, and is ideal for use in linked lines.
