S 400 GS Designed to grind shaving cutters and master gears using the generation method, the S 400 GS is the fourth generation of its kind and sets new standards in terms of precision, reliability and user-friendliness. 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 roll motion is steplessly 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 S 400 GS is now available with an eleventh CNC axis. This new axis makes it possible to grind larger tooth widths whilst enhancing the quality of the finish. Moreover, machine set up is also quicker. Why set yourself limits? We look forward to illustrating the advantages of the new S 400 GS to you.
