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.

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.

This machine is very suitable for precision production testing of spiral and hypoid bevel gears with shaft angle 90°. The gear spindle is vertical and the pinion spindle is horizontal. The pinion cone distance can be adjusted while the machine is working in order to find the optimal mounting position whereby the gear is "loaded" with a preset torque. The axial pinion position can be adjusted until the quietest meshing position of the traction flank is found. Likewise, the thrust flank can be tested during the return run. Marking compound is sprayed on both sides of the teeth so the flank contact pattern can be seen. Working cycles, as well as the positioning in the tooth gap, are automatic. The gear quality can be assessed by recording the harmonic frequencies, which are displayed on a separate monitor and which can be analyzed with a RHF Control. Machine can be used for soft testing of production parts, as well as for mating sets of hardened gears and pinions prior to lapping, and for final testing after lapping to select the optimum pinion mounting distance. Also ideal for lab work, processing, and quality control.
