The S41 CNC universal cylindrical grinding machine is designed to increase precision, surface quality and metal removal rates while decreasing cycle time. The machine bed is made of Granitan S103 mineral casting, which provides the integrated guide system with a stable basis for absorbing the high forces that occur during grinding with high metal removal rates, the company says.
The StuderGuide guideway system includes hydrostatic and hydrodynamic guide systems to avoid the slip-stick effect and floating of the slide. Solid gray cast iron slides rest completely on the guideways over the entire travel.
The longitudinal slide (Z axis) has a ground work table that carries the workhead and tailstock, and additional accessories and devices. A ground T-slot over the entire length of the guideway enables optimal positioning of dressing tools, the company says. The cross-slide (X axis) supports the wheelhead. The slides are moved by linear direct drives at travel speeds ranging to 20 m/min. and axis system resolutions of 10 nm. This enables high-precision and highly efficient grinding while reducing auxiliary times, the company says.
A direct drive also swivels the turret wheelhead (B axis) and positions the grinding wheels with a range of less than 1".
Other features that extend workpiece range include higher workheads, a hydraulically clamped tailstock for the heavier workpieces, and as many as four external grinding wheels or three internal grinding spindles for more than 30 grinding head combinations.
Also on display at the show will be the company’s S33 grinder, S22 production platform, S242 combined machining system and CT550 grinding machine.
Editor PickWhen Grinding Is Like Turning
This shop leverages a high-speed peel-grinding process that resembles turning to effectively grind challenging materials such as carbide. Inherently low grinding forces mean high material-removal rates are possible.
