|Our CG-Line machines have many technical highlights, from which the most important ones will now be explained:|
Grinding- and regulating-wheel-spindles are made out of high quality alloy steel (SNCM439JIS), precision ground, artificially aged, induction hardened and therefore maintenace free for life-time. The triple hydrodynamic bearing, which sticks out by its longevity allows a very smooth operation.
The tilt-angle of the regulating-wheel is ±5º. This easily allows different feeding speeds for thrufeedgrinding.
The swivel-angle of the upper slide is ±3º. The centre of rotation lies in the middle of the wheel. The workrest remains unaltered, for it is mounted on the lower slide. With just one screw the cylindricity to the wheel can be quickly and easily adjusted.
For driving the regulating-wheel a servo-motor is used whose speed can be continuously adjusted. By the utilization of the servo-motor, which is directly connected to the spindle via a special belt , speed oscillations and vibrations will be made almost impossible, which results in perfect roundness of the work-piece.
Hydraulic Dressing Units
Grinding- and regulating-wheel do have hydraulic dressing units, whose speed are continuously adjustable. The guides are precisely hand scraped. This allows a smooth dressing with a high accuracy.
