Setting New Standards in Terms of Precision
The GS 400 Tool Grinder is designed to grind shaving cutters and master gears using the generation method.
Workpiece Ø: 68 – 400 mm
Module range: 0.5 – 15 mm
Max Face width: 70 mm
Designed to grind shaving cutters and master gears using the generation method, the GS 400 is the fourth generation of its kind and sets new standards in terms of precision, reliability and ease of use. Samputensili interpolation software calculates the profile to be ground and coordinates the linear movement of the transverse slide with the rotary movement of the work spindle. The resulting rolling motion is infinitely adjustable in terms of the roll diameter, and indexing blocks are no longer required. Roll motion and index movement are now numerically controlled and both generated by the same motor. All movements are actuated by linear and rotary digital drives. An integrated measuring unit automatically checks the quality of the first tooth ground without having to unclamp the workpiece and waste precious time.
NEW – The GS 400 is now available with an axis X11 CNC . This new axis makes it possible to grind larger tooth widths while enhancing the quality of the finish. Moreover, machine set up is also quicker.
