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. Condition : Very good - machine can be inspected here under power Delivery : Ex stock, as inspected Payment : Net, after conclusion of contract Thank you for your interest. We always have a good selection of gear machines available. Please let us know what you need.
