T-Max® P
Productive external turning of medium-sized to large components
Insert seat
Clean and inspect insert seat for damaged locations and support for the cutting edge
Shims and shim seats
Ensure that shim corners have not been knocked off during machining or handling and that shim seats have no edge buildup
Contact faces
Check supporting and contact faces, making sure there is no damage or dirt.
Clamping
In boring operations, it is important to have the best possible clamping. If not supported, the overhang will be increased, which might cause vibration.
Application tips
Avoid chip jamming
Turn towards shoulder (steps 1–4), and stop before the final dimension of the shoulder. Keep the same feed rate for all four steps to avoid chip jamming. The final cut (5) of the shoulder is recommended to be done in one vertical cut, starting from outer diameter towards inner diameter.
Avoid vibrations
Machines with two turrets, an upper and lower turret, are recommended to avoid vibrations. The setup will level out the forces and stabilize the whole process, avoiding vibration and bending of the part.
