Tool, Template, Cassette, and Method for Grooving a Roller

A set comprising:

• a cassette for a tool for machining of a workpiece,
• wherein the tool comprises a tool body and the cassette comprises at least one machining device,
• the machining device is receivable on and/or in the cassette;
• a protrusion for engaging in a gap in the tool body is arrangeable or arranged on the cassette;
• a template for the tool,
• wherein the template comprises a protrusion for engaging in the gap in the tool body, and
• the template has a template opening for receiving the cassette.

A method for fluting a roller by way of a tool, wherein the tool comprises a tool body and/or a cassette for receiving two pairs of at least two cutting devices, arranged substantially parallel to one another and in a row, a first pair of cutting devices is arranged for a first machining direction and a second pair of cutting devices is arranged for a second machining direction substantially opposite to the first machining direction, the method comprising the steps of:

• positioning the first pair on the roller;
• rotating the roller about the roller axis in a first direction of rotation and, at substantially the same time, moving the tool along the roller axis in the first machining direction in order to produce a flute in the roller;
• positioning the second pair on and/or in the flute;
• rotating the roller about the roller axis in a second direction of rotation and, at substantially the same time, moving the tool along the roller axis in the second machining direction along the flute.
