Parting and grooving

Maintenance of parting and grooving tools

Establishing a routine for tool maintenance in the workshop will prevent problems and save money.

Check the insert seat

It is important to ensure that the insert seat has not been damaged during machining or handling. Make sure the insert seat is free from the dust or metal chips that are produced when machining. If necessary, clean the insert seat with compressed air. If CoroCut® SL blades are used, it is also important to check and clean the coupling between the head and the bar when changing the cutting head.


Torque wrench

To get the best performance out of screw-clamp tool holders, a torque wrench should be used to correctly tighten the insert. A too high torque will affect the performance of the tool negatively and cause insert and screw breakage. Torque that is too low will cause insert movement, vibrations and degrade the cutting result. Refer to the laser marking on each tool holder, or to the Main catalogue/Turning tools for the correct insert tightening torque (Nm).


Clamping screws

Use a torque wrench to tighten the screws to the correct torque. Change the insert clamping screw regularly. Apply sufficient screw lubrication to prevent the screw from seizing. Lubricant should be applied to the screw thread as well as the screw head face. Replace worn or damaged screws.
