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.

Following function can be preset: Clockwise / anticlockwise movement, lapping torque, pulling and pushing movement, 4 lapping programs, etc. * Protective hood for crown gears with a diameter up to 400 mm, with automatic closing mechanism. * Separate switch cabinet. * Separate hydraulic unit, etc. Price, ex stock EUR 29,500.-- The lapping process employed by this machine greatly improves the running performance of bevel gear pairs. Pinions and gears are meshed by up to three additional movements (axial, radial and vertical) which are controlled by cams. Tooth flanks are smoothed with the help of lapping medium, and contact patterns are corrected as necessary.
