chipbreakerFor front turning operations ｜ Swiss CNC Lathes
Negative insert developed for Swiss lathes
Designed with the sharpness and low tool pressure of a positive insert while reducing insert costs
Outstanding performance even machining small diameter parts while increasing corners per insert.

| Coated grade | Material | Operation type | Cutting speed (m/min) | Feed (mm/rev) | DOC (mm) |
|---|---|---|---|---|---|
| ST4 | Stainless | OD Turning continuous | 50 - 120 | 0.03 - 0.15 | 0.3 - 2.5 |
| QM3 | Alloy steel / carbon steel / hardened material | ||||
| DM4 | Difficult-to-cut material / titanium alloy | 30 - 100 | |||
| TM4 | Non-ferrous / aluminum / plastic / general purpose | 50 - 180 |
Cost reductions for Swiss machining
- Achieves performance comparable to a positive insert with the benefit of additional corners

| ST4+ UL chipbreaker | 1000 pcs / corner |
| Competitor's molded chipbreaker (PVD coated carbide) |
200 pcs / corner |
UL insert obtained good machined surface with its sharp cutting edge.
UL combined with the ST4 grade, for stainless steel machining, achieved 4 x longer tool life compared to the competition.

UL sharpness provided stable dimensional results and reduced tool pressure
When cutting speed increased, BUE was eliminated further increasing tool life from 600 to 800 pieces /corner
