TOYOKAWA―June 21, 2023―OSG Corporation today announced the expansion of its AE-N DLC coated end mill series for copper electrodes with the AE-CPR-N end mill.
The AE-CPR-N is a long neck corner radius carbide end mill designed for high-efficiency finishing of copper electrodes. Its 3-flute specification contributes to high-efficiency machining and long tool life. Moreover, the AE-CPR-N’s unique flat cutting edge geometry, superior corner R precision and cutting edge diameter accuracy allow high precision machined surface quality. With the addition of OSG’s DLC-IGUSS, a thick film type coating that suppresses wear on the cutting edge, both high tool durability and good machining accuracy can be achieved. Due to its smooth surface and extremely low coefficient of friction, DLC-IGUSS is extremely effective against non-ferrous metals such as copper alloys, which require welding resistance and lubricity.
The AE-CPR-N is available from diameter 0.2 mm to 6 mm with a wide variety of neck lengths. Sizes up to diameter 1 mm employ a 2-flute specification. All sizes above diameter 1 mm are engineered with a 3-flute specification.
