加工大型平面用普通面铣刀(D≥315mm),因整体重量大,在机床上装、换刀相当困难.为改善和解决这一问题,开发了一种可转位帽盖式密齿面铣刀.该刀具在国外以瑞典Sandvik公司的产品最具代表性.我厂利用加工中心、数控铣床等先进设备,可承接生产系列化帽盖式密齿面铣刀.可转位帽盖式面铣刀(根据被加工工件表面的性质)通常分为密齿粗切刀(左、右刃)(见图1)和密齿精切刀(左、右刃)(见图2)两种.精切刀若配有大圆弧刮光刀片,加工表面粗糙度不超过Ra1.6μm.
Due to its large overall weight, it is very difficult to machine and change tools for machining large flat surface milling cutter (D≥315mm) .In order to improve and solve this problem, an indexable cap type face milling machine Knife. The tool abroad in Sweden Sandvik company’s most representative of the products. I use the machining center, CNC milling machine and other advanced equipment, to undertake the production series of cap-type Milling Milling Cutter. Milling cutter (according to the nature of the workpiece surface) is usually divided into dense coarse tooth cutter (left and right blade) (see Figure 1) and fine tooth fine cutter (left and right blade) (see Figure 2) two. If the cutting knife with a large circular scraping blade, the processing surface roughness does not exceed Ra1.6μm.
