In parting and grooving, processing safety and production efficiency are two important aspects. Choosing the right tool and setting it up correctly can avoid many problems when cutting off. Problems include flash and burrs, tool breakage, chip jams, poor surface quality on parts with complex grooves, incorrect coolant pressure, long overhangs and high levels of vibration, which can ultimately result in expensive parts being scrapped. To help you avoid these specific problems and successfully perform parting and grooving, we offer the following suggestions and tips.

Primary considerations for parting and grooving

These primary considerations will influence the selection of parting and grooving tools and how they will be applied.

groove or surface

Consider the following quality requirements for the groove or surface to be machined:

Application type (e.g. parting off or internal grooving)

cutting depth

cutting width

Tool nose radius

Quality requirements (tolerances, surface quality, etc.). Are wiper inserts required to achieve acceptable surface quality? Wiper inserts provide better surface quality while 

maintaining cutting parameters

Component

After considering the quality requirements, look at the part:

Does the material have good chip breaking properties?

Is chip evacuation/chip control a critical issue?

Batch size - single flute or batch flute machining? Volume production requires the use of optimized Tailor Made custom tools for maximum productivity

Can the workpiece be clamped safely?

machine tool

Machine tool considerations include:

Stability, power and torque, especially for larger parts

Cutting fluid and coolant supply

Is high-pressure coolant needed to break long-chip materials?

Tool change time/number of tools in the turret

Speed limits, especially for bar feeders and small diameters

Is there a counter spindle or tailstock?
