- Preserves the workpiece micro-contours
- Introduces compressive residual stresses into the workpiece
Description
Our hydrostatic roller burnishing tool is used for the fine machining of bores or shafts. In this process, one or more balls are pressed against the material surface by coolant pressure, which smooths the workpiece surface and introduces compressive residual stress. This method is suitable for machining materials up to a hardness of 65 HRC, clearly distinguishing it from conventional roller burnishing tools. Only sufficient coolant pressure at the machine is required for machining. The pressure can be provided either directly through the spindle (CTS) or by an external pump. Machining can be CNC controlled or manual, on both lathes and milling machines. For very hard workpieces with small machining diameters, pressures up to 400 bar may be necessary.

Tool structure
The WHS type hydrostatic tools consist of a carrier shaft for holding the balls and a holder designed according to your specifications. Coolant is usually supplied through the holder, and in special cases, the tool can also be connected directly to an external pump.
Machining
For machining, the workpiece or the tool is set in rotation and subjected to pressure. The rotation and the pressure of the balls compress and smooth the surface. Since the movement of the balls is not mechanically restricted, a uniform roller burnishing result is achieved. This is particularly advantageous when micro-contours have been incorporated into the material surface and are to be preserved.
