The small diameter round head that Toshiba Tungaloy company produces stands milling cutter, basically use at the half rough machining of the mould and semifinishing machining. Cutting tool characteristic: ① forms whole small diameter set, EWD establish milling cutter to take a power, HWD can change for cutting head establish milling cutter. Former diameter limits is 10 ～ 25mm, latter is 10 ～ 42mm. ② treatment efficiency is tall, e/HWD establishs milling cutter to use small cut cutting of deep big feed, the heat in metal cutting that blade needle produces is inferior, accordingly cutting rate can rise 2 ～ 3 times; Bit is a circle, the generated ply that cut bits is lesser, because this every tine feed is optional bigger. ③ cutting tool takes aspirated aperture, use compress air to will cut bits to be blown, won't produce the phenomenon that block bits up. ④ stands milling cutter can undertake step cutting, grooving, cut a variety of operation such as aperture of oblique plane, treatment. Material of ⑤ razor blade is AH120 of coating hard alloy, hear resistance is tall, life is 3 times of other company razor blade. CNC Milling
