日本日立(株)开发一种适于MC加工的面铣刀。该铣刀比旧式刀体直径小10％,重量也减轻25％～30％。其刀体端面振摆精度为旧式刀体的1/5(25μm～5μm),切削加工面精度为5μm～8μm。其铣削抗力比旧式降低30％,可实现大进给(由550m/min提高到710m/min)。其最大铣削深度可达1.2mm。规格有:φ80、φ100、φ125、φ160、φ200、φ250mm;刀片尺寸为12.7mm和15.875mm。 Japan’s Hitachi (strain) to develop a suitable MC machining surface cutter. The cutter is 10% smaller than the old body diameter, weight is also reduced by 25% to 30%. The end of the body swing accuracy of the old body of the cutter 1/5 (25μm ~ 5μm), cutting the surface accuracy of 5μm ~ 8μm. Its milling resistance is reduced by 30% over the previous version, enabling large feeds (up from 550m / min to 710m / min). Its maximum milling depth of up to 1.2mm. Specifications are: φ80, φ100, φ125, φ160, φ200, φ250mm; blade size 12.7mm and 15.875mm.
