Grooving Inserts Application and Maintenance Guide
Grooving inserts produce internal and external grooves, recesses, and perform parting-off operations. Proper application ensures groove quality and insert longevity.
I. Insert Selection
- Width: Select the insert width matching the required groove width. For wider grooves, use multiple passes or a wider insert.
- Geometry: Neutral geometry for general grooving. Right or left-hand for specific approach angles.
- Grade: Select based on workpiece material as with general turning inserts. Consider tougher grades for interrupted cuts.
II. Application Techniques
- Set the tool precisely on center height. Above or below center affects clearance and cutting forces.
- Use the recommended feed rate for the insert width. Narrower inserts require lower feed rates.
- Apply coolant directly to the cutting zone. Through-tool coolant is ideal for deep grooving.
- For deep grooves, use pecking cycles to break chips and prevent packing
III. Maintenance
- Inspect insert edges after each operation. Replace at first sign of chipping or excessive wear.
- Clean the insert pocket and clamp thoroughly before inserting new inserts
- Check that the insert seats correctly in the pocket; improper seating causes insert movement and breakage
- Index inserts when one cutting edge shows wear to maximize insert utilization
