The fixture represents the connection between machine and tool. The basic element is connected by a form-closed clamping bar to the tool fixture.

The rolling unit guides and supports the roll and is connected to the fixture and the basic element. It is optimally adapted to the processing task. The rolling unit is connected with four screws to the basic element.

The basic element contains the spring of the single-roller tool. This spring enables you to define the rolling force in dependence to the tool preload. The rolling force can be determined by using the chart.
If the exact value of the force is required, the optionally available testing device has to be used.
