Tooling Technology
Fast, Precise Cylindrical Grinder
United Grinding Technologies (UGT), Miamisburg, OH, introduces the Studer S41 CNC universal cylindrical grinder, which features electric direct drives for longitudinal and cross slide, as well as the swivel axis for the wheel head. Its Gran- itan S103 machine bed pro- vides a solid, rigid and ther- mally stable machine, ideal for absorbing the high forces that occur during grinding with high metal-removal
rates.
The new StuderGuide
guideway system ensures precise move- ment of the longitudinal and cross slides. The system combines the advantages of hydrostatic and hydrodynamic guide systems and avoids the slip-stick effect or float- ing of the slide. With this maintenance-free guide system, Studer guarantees a straight-
ness of less than 0.0001 in. over a measured length of 37.4 in.
The longitudinal slide (Z-axis) has a ground worktable that carries the work head and tailstock as well as additional accessories and devices. Longitudinal and cross slides are moved by linear direct drives and are rated to 66 ft./min. Maximum
workpiece weight is 551 lb.
As many as four external grinding wheels or three internal grinding spindles enable
more than 30 grinding-head combinations. The grinding wheels are driven by motor
spindles rather than belt drives; the machine can be equipped with motor spindles for high-speed grinding; internal grinding spin- dles with speeds from 6000 to 120,000 RPM can be used; and automatic bal- ancing systems and frequency convert- ers for each external grinding spindle allow grinding processes to be matched to the respective conditions of use.
