*This press release was originally published in Japanese on October 27, 2016.
Sumitomo Electric Industries, Ltd. has developed the new AC6020M grade for finishing and general turning of stainless steel and launched it in November 2016. This product ensures stable machining and long tool life.
AC6020M-series tool inserts
Owing to its excellent properties, such as corrosion resistance, thermal resistance and machinability, demands for stainless steel are growing year by year. On the other hand, its high work hardening rate causes chipping of the cutting edge, and low thermal conductivity prevents cutting heat dissipation, thereby raising the temperature at the cutting edge and promoting plastic deformation.
To overcome these disadvantages, the new AC6020M grade was developed for stainless steel turning. Together with the other AC6000M series grades, it is possible to machine all kinds of stainless steel under all cutting conditions from roughing to finishing, continuous to interrupted machining, and low-speed to high-speed machining.
- 1. Features
-
- Utilizing a new carbide substrate that exhibits both wear resistance and toughness, along with Sumitomo Electric's proprietary coating technology "Abosotech Platinum™," this product has doubled the fracture resistance of conventional inserts.
- The smooth surface treatment of the coating layer drastically reduces adhesion on the cutting edge to achieve stable machining by preventing sudden damage and chipping to the cutting edge.
- This insert is capable of high-speed machining up to Vc = 200m/min.
- The prolonged tool life reduces insert consumption and tool replacement frequency while the improved machining efficiency reduces machining time, thereby significantly reducing machining costs.
- 2. Lineup
-
Negative type inserts 133 items Positive type inserts 91 items Total 224 items - 3. Sales Plan
¥40 million in the first year and ¥300 million per year after 3 years
- 4. Pricing
-
Pricing has been set at the same level as similar conventional products. The standard price (list price) of each item differs by type.
