OSG adds AE-CRE-H high efficiency radius type carbide end mill and AE-HFE-H high feed radius type carbide end mill to its AE-H end mill series for high-hardness steels
TOYOKAWA―September 20, 2023―OSG Corporation today announced the expansion of its AE-H end mill series for high-hardness steels with the AE-CRE-H high efficiency radius type carbide end mill and AE-HFE-H high feed radius type carbide end mill.
The AE-CRE-H radius type carbide end mill features multi-flute and unequal spacing teeth specifications to suppress chattering for stable and high-efficiency roughing of high-hardness steels. To achieve both cutting edge strength and good chip evacuation, the AE-CRE-H is engineered with a 2-stage gash shape and a large chip pocket. Furthermore, the AE-CRE-H features a large positive R shape and short flute length with high tool rigidity to allow large depth of cut and high-feed milling, which is ideal for high-speed direct engraving. The AE-CRE-H is available from diameter 1 mm up to 13 mm with a total of 13 items. A 4-flute specification is applied for outer diameter up to 2 mm. A 5-flute specification is applied for outer diameter from 3 mm and above.
The AE-HFE-H high feed radius type carbide end mill reduces cutting resistance with its unique composite radius shape, and enables high-speed, high-feed machining even at overhang length of L/D = 7 in high-hardness steels. Similar to the AE-CRE-H, the AE-HFE-H also features a 2-stage gash shape for achieving both cutting edge strength and good chip evacuation with a large chip pocket. Furthermore, with its unequal spacing teeth configuration, chattering can be suppressed to enable stable and highly efficient machining. The AE-HFE-H is available from diameter 1 mm up to 12 mm with a total of 9 items.
For outer diameter 5 mm and above, both the AE-CRE-H and AE-HFE-H are configured with a straight edge specification that minimizes shape change with consideration of regrinding, which contributes to the realization of resource circulation and a sustainable manufacturing environment. In addition, these end mills are coated with OSG’s DUROREY coating for high-hardness steel, which exhibits high chipping resistance even in work materials of over 60 HRC, enabling long tool life and high-speed milling.
OSG’s AE-H end mill series for high-hardness steels now includes multi-flute, radius, ball, long neck and exchangeable head configurations to accommodate a wide range of applications and milling methods with superior performance.
