Wheel set re-profiling lathe
max. ø 500 mm | TB500
CAORLE
The turning of the brake shoes, with regards to the previously taken internal diameter of the drum, allows to obtain a perfect matching between shoes and drum for the full braking efficiency from the beginning. The operation is executed on the same direction of the wheel rotating direction in order to compensate eventual clearances.
Moreover, it is extremely easy and fast the positioning of the lathe on the wheel hub..
Centering to the hub
TB500 has to be centered to the wheel hub by means of some centering rings to be placed on the wheel axle.
The connection can be executed with or without the internal bearing mounted, and the operation is extremely fast also because there is not a need of a further clamping.
The intermittent feeding
The intermittent feeding acts on the displacement of the tool-holder group and it allows the tools to engrave parallels circles on the brake shoes surface. We avoid in this way the formation of the classical spiral effect on the turned surface which is the main responsible of the axial displacement of the brake shoes and of their early wear and tear.
