Accessories / Special Features:

* FANUC CNC Control, Model 150 MB, for 7 axes, with monitor and direct input. Automatic calculation of all workpiece and grinding parameters.
* Extensive coolant equipment with filter system, band filter, etc.
* Driven grinding wheel dressing device with CNC dressing control for automatic compensation of form and diameter after every dressing.
* Gear grinding is effected either in single component operation using a conical cup wheel (Gleason 30°), or with a cylindrical cup wheel. These grinding wheels can be made of CBN, or of traditional “dressable” aluminium oxide material (question of cost). Grinding with a conical grinding wheel is of advantage with regard to heat build-up and quality of tooth contact pattern. Therefore these pairs of bevel gears (for automotive industry) can be generated in high quality with consistent accuracy, economically, and with short set-up times.
