Maintenance of cutting grooves

Develop cutting tool maintenance routines in the workshop to avoid problems and save costs.

1. Check the tool holder

Make sure the tool holder is not damaged during processing or loading and unloading. Make sure there is no dust or chips on the cutting tool holder. Clean the tool holder with compressed air if necessary. If a  tool is used, the interface between the cutting head and the boring bar must also be checked and cleaned when the cutting head is replaced.

2. Torque wrench

For optimum performance of the screw clamping shank, the tool should be tightened properly using a torque wrench. Excessive torque 
 will negatively affect cutting tool performance and lead to tool and screw breakage. Too little torque will cause the tool to move, vibrate and reduce cutting quality. For correct tool tightening torque (Nm), refer to laser marking on each shank or turning tool main catalogue.

3. Tighten the screws

Tighten the screws to the correct torque using a torque wrench. Replace the cutting tool clamping screws periodically. Apply sufficient amount of screw lubricant to prevent the screw from sticking. Lubricant should be applied to the thread and the surface of the screw head. Replace worn or damaged screws.
