日本OSG公司开发的F2139型硬质合金球头立铣刀,是一种机夹式精加工刀具,其刀片形状独特,刀片采用插入式卡紧方式,半圆形圆弧刃参加切削,一枚刀片带有两个对称的切削刃.因此,切削时刀具负荷均衡,振动小,可在高速进给的条件下实现高精度加工.用于模具加工时,可获得与传统的整体式、焊接式球头立铣刀相近的加工精度,刀具成本较低. Japan OSG company developed F2139 carbide ball end mill is a clip-type finishing tools, the unique shape of the blade, insert the use of inserts clamping, cutting edge to participate in cutting a semicircular arc, a The blade has two symmetrical cutting edges, so that when the cutting tool load is balanced, the vibration is small, high-precision machining can be carried out under the condition of high-speed feeding.It can be used with the traditional integral type, welding type Ball-end mill similar processing accuracy, lower tool costs.
