epoch21 立铣刀是日立公司最新产品之一,为了进一步扩大其使用范围,该公司加速了系列产品的开发.新的epoch21 立铣刀系列仍采用六边形截面切削刃形,它可在高转速大进给量条件下,进行高效率切削加工.与过去的硬质合金立铣刀相比.epoch21 立铣刀系列产品的工具寿命大幅度延长;加工表面粗糙度和加工表面精度均有很大改善;一把刀具可满足多种被加工材料的切削需要.如在加工S50C、SKD11等材料时,与一般硬质合金立铣刀相比,工具寿命提高9倍;加工S50C、SUS304材料时,加工效率为一般硬质合金立铣刀的10～15倍.在加工表面粗糙度方面,用一般硬质合金立铣刀
The epoch21 end mill is one of Hitachi’s newest products and the company has accelerated the development of its products to further expand its use.The new epoch21 end mill series still features a hexagonal section cutting edge, Large feed rate conditions, for high-efficiency machining. Compared with the past cemented carbide end milling cutter .epoch21 end mill series of tools to significantly extend the tool life; machining surface roughness and machining surface accuracy are very large Improve; a tool to meet the cutting needs of a variety of materials to be processed. Such as processing S50C, SKD11 and other materials, compared with the general carbide end mill, tool life increased by 9 times; processing S50C, SUS304 material, Processing efficiency for the general carbide end mill 10 to 15 times in the processing of surface roughness, with the general carbide end mill
