Motor mounting plate of Ghost Rabbit GR1


Motor mounting plate of Ghost Rabbit GR1 (0 min 34 sec)


The first part of this video shows the CNC processing of an actuator disk for the diff lock of the Ghost Rabbit GR1. The part will be heat treated after the processing.

The second part of the video shows the motor mounting plate for the same car.
While most of its shape is processed on a CNC milling machine, the final steps of machining the bearing seats and some other surfaces which have all to be concentric are done on a CNC lathe.

A CNC milling machine is by design not capable of providing the same precision for these steps as a lathe. A lathe gives truly round and concentric results because the part itself rotates, not the tool.
A CNC milling machine makes a circle in many small steps, it interpolates the rounding. This is usually sufficient, but a lathe is clearly superior here.

Therefore we go the extra mile and use a lathe for these important steps of the processing. By doing so we achieve a precision for the bearing position of 0.005 mm."
