How To Set Up A Parting Off Tool

Holding the tool against the face of the part may help with this.

How to set up a parting off tool. Set the tools height lay it against the parts face and lock the tool. The solution when using carbide inserts for parting off it is best only to use then to within a millimetre or two from the middle of workpiece. Choose an insert geometry designed for parting-off.

3 Go all modern and use an insert type parting blade. If the carbide cutter has an angle on it it is usually quite small. Put a ruler between the tool tip and the workpiece and crank it down so the ruler is held between the two.

A good way to do this is to hold the tool against the face of the part. Parting tools are used to create narrows grooves and cut off parts of the stock. Heavier the better with a directly held parting tool preferably next size up for extra blade stiffness.

Even if the tool is set exactly on centre before parting these effects will tend to force the tool below centre as the work progresses. As I see it the front mounted tool will tend to be forced downwards while the work is trying to climb the tool. Use a tool with the shortest possible overhang and a secure insert clamping for best stability.

The parting tool 116 x 516 x 4 is set at an angle of 5 degrees from the horizontal whilst the chamfering tool is horizontal.

Ensure the parting tool is perpendicular to the face of the chuck you can alternatively use a dial indicator. For an optimal parting tool set-up use a tool holder with a short overhang to avoid vibration. A narrow insert creates lower cutting forces and saves material.
