– Increased productivity with stable chip control in various machining
• Stable tool life
– Reduced cutting force brings stable tool life at high speed and high feed
NC3215 · NC3225
The surface of forged steel that is commonly used for automobile parts is harder and tougher while the inside is soft. Bearing steel also has those characteristics of high toughness and hardness. Machining these kinds of steel repeatedly causes built-up edge on cutting edges and chipping off the edge, which is one of the main reasons of falling productivity and causing unstable tool life.
Mass production of automobile parts requires faster cutting speed and higher feed along with much longer tool life than before.
NC3215 / NC3225 are a new CVD coated grades for turning application of automobile components, made with forged steel and bearing steel. NC3225 is the first choice of an universal grade for machining forged parts while NC3215 is ideal for high speed and continuous machining. Coating, applied to these inserts, has been much improved than conventional ones with higher wear resistance and stability on cutting edges.
LP / MP Chip breakers have two step dots at the corner and bring measurable increase in productivity when machining forged steel at high speed(max. 350m/min) and high feed(max. 0.35mm/rev).
NC3215 / NC3225 in combination with LP / MP ensures a precise cutting action as well as maximum cutting efficiency when machining automobile components.
