US735 Grade Technology
The US735 grade is Mitsubishi's specialized CVD turning insert material for M-class stainless steel. It features a high-toughness substrate combined with a coating that significantly reduces built-up edge (BUE). This makes it an elite long-tail industrial tool for high-mix, low-volume production where reliability is key.
MS Medium-Light Breaker
The MS chipbreaker is specifically optimized for medium-light cutting of gummy materials. Its sharp rake angle reduces cutting resistance, preventing the work-hardening of the stainless steel surface while maintaining efficient chip evacuation at lower feed rates.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed per Rev ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 60 - 150 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.5 mm |
| High-Temp Alloys (Inconel) | 30 - 60 m/min | 0.08 - 0.15 mm/rev | 0.3 - 2.0 mm |
