United Grinding Technologies’ Studer S41 CNC universal cylindrical grinder has a longitudinal and cross slide, as well as a swivel axis for the wheelhead. It features electric direct drives, which move to the working position swiftly and precisely, the company says. 
 
The developers based this grinder on a predecessor machine while adding a number of outstanding design features. The Granitan S103 machine bed provides a solid, rigid and thermally stable S41. Thanks to its thermal behavior, the machine bed is designed to equalize brief variations in temperature so that the machine operates with consistently high precision, even with changing ambient temperatures. The guideways of both the longitudinal slide and the cross slide are molded directly into the machine bed. To ensure that the high forces that occur during grinding with high metal removal rates are optimally absorbed into the machine bed, the guideways have a larger spacing. 
 
The StuderGuide guideway system ensures high precision of the longitudinal and cross slides when both stationary and during movement. The StuderGuide system uses the advantages of hydrostatic and hydrodynamic guide systems and avoids the slip-stick effect or floating of the slide. Also contributing to the machine's high precision is the fact that the solid gray cast iron longitudinal and cross slides rest completely on the guideways over the entire travel. With this maintenance-free guide system, UGT guarantees a straightness of < 0.0001” over a measured length of 37.4”.
 

The longitudinal slide (Z axis) has a ground worktable that carries the workhead and tailstock as well as additional accessories and devices. A ground T-slot over the entire length of the guideway enables optimal positioning of dressing tools. The cross slide (X axis) supports the wheelhead. Longitudinal and cross slides are moved by linear direct drives and, with up to 66 fpm, achieve 4 times higher travel speeds and axis system resolutions of 10 nanometers. This enables high precision and highly efficient grinding, as well as making a huge contribution to reducing auxiliary times, the company says.
