CNC machine deburring tool COFA-X

metalcross-holefor metals

Each COFA-X tool is designed for the individual application. It is a solution for deburring the edges created by intersecting bores (crossbores) having a main bore to cross bore ratio of 1:1. It can also be used for intersecting bores with offset axes. The COFA-X starts from a bore diameter of 5.0 mm. For each application, we require a precise application description in order to provide the correct solution. Please define the parameters and characteristics of the application as precisely as possible.

The tool body is a single unit and the blade is pre-tensioned so that it can follow the large bore unevenness. Two screws secure the replaceable spring to the tool body. After the deburring process is completed, this spring returns the blade to its starting position. The coated carbide blades are designed either exclusively for forward or backward cutting. This relief of the tool body is required for the COFA-X to move off-centre into the bore, as the blade cannot retract due to the pretension in one direction and orientation. Process steps description The COFA-X removes burrs from the very uneven edges caused by intersecting internal bores. This mechanical deburring solution for crossbores can be used in CNC operations and significantly improves process reliability.
