​Tool Setup: How to Use Parting and Grooving Tools

Good quality in parting-off and grooving is mainly dependent on the tool system and how it is used together with the cutting material.

Overhang

For an optimal parting tool setup, use a tool holder with a short overhang to avoid vibration. We recommend using a sub-spindle, if available.

When machining with long overhangs, it is especially important to mount the bar correctly to ensure enough clamping contact. Recommended clamping length is 4 × bar diameter, D. This will result in a stable parting tool setup. Cylindrical adapters can be clamped in split sleeves. Large adapters can be clamped using two split bearing caps.

Tool holding

The right tool holding solution can improve the productivity and performance of the cutting tool dramatically.

Coromant Capto® is a modular, quick change tooling concept which, when directly integrated in the spindle, increases stability and versatility in, for example, multi-task machines, machining centers with turning capability, and vertical lathes.

EasyFix™ sleeves are a set-up time reducing solution for cylindrical adapters. A spring plunger mounted in the sleeve clicks into a groove in the bar to guarantee the correct center height.

The QS™ holding system is a quick change tool holder to maximize effective production time in sliding head machines.

Silent Tool™ tool adapters are designed to minimize vibration through a dampener inside the tool. These tools are mostly used for long overhangs, however, even with shorter overhangs (3×D), large productivity increases and surface quality improvements are to be gained.

Parting blades

Parting blades and tool blocks offer a tool system for parting-off, deep grooves, and long overhangs. Precision coolant is optional for all blades. No connection hoses or pipes are needed. Adapters are available for most machine types.
