* The Machine was partially rebuilt and electrically modernized by WELTER Co. Germany and equipped with PLC Control System make LAUER and containing a SIEMENS System S 5 with SIEMENS Drives, all Errors are immediately reported on a display, this makes the use of the machine much easier! * Hydraulic workpiece clamping for both spindles. * Automatic lapping process with 4 lapping programs:Following functions can be preset: Clockwise / anticlockwise movement, lapping torque, pulling and pushing movement, Lapping time, and steplessly adjustable braking force. * Various Braking forces can be preadjusted by switches and Potentiometers * Protective hood for crown gears with a diameter up to 400 mm, with automatic closing mechanism for the cover and the front door. * Separate switch cabinet.* Separate hydraulic unit, built-in lapping agent pump and manual brake,etc. 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.
