Abstract
A device for superfinishing of ground surfaces of workpieces has a finishing block, which can be displaced by means of a drive device in a plane which is orthogonal with respect to the surface to be worked and is pivotable in this plane. By means of this it is possible to create a device of relatively small structural size, by means of which any arbitrary surfaces of workpieces can be treated.
Claims13
A device for superfinishing treated surfaces of a workpiece, comprising:
- a clamping device for supporting the workpiece;
- a finishing block for finishing a surface of the workpiece;
- a holder for supporting said finishing block;
- a multi-axis drive device for driving said holder and effecting a multi-axis relative movement between the surface of the workpiece to be treated and said holder in a plane which is orthogonal to the surface of the workpiece to be treated;
- a control unit for controlling said multi-axis drive device, said control unit including:
- input means for inputting the profile of the surface of the workpiece to be treated to the control unit;
- and electronic calculating means;
- and
- a pivoting device connected to said holder and said control unit, wherein:
- said holder is seated pivotably about a virtual pivot axis by means of said pivoting device, said virtual pivot axis being orthogonal with respect to said plane;
- the pivot angle of said holder correspond to the position of said finishing block is determined by means of said calculating means;
- and
- said pivoting device is controlled by said control unit.
