2\u3001 Tool selection<\/p>\n\n\n\n
The tool selection is based on the processing capacity of the machine tool, the performance of the workpiece material, the processing form, the cutting amount and other relevant factors. The general principle of tool selection is: easy installation and adjustment, good rigidity, high durability and precision.<\/p>\n\n\n\n
1. Select the tool according to the processing capacity of the machine tool<\/p>\n\n\n\n
1) High speed machining center: coating cemented carbide tool series and Daijie series tools are generally used. It is not recommended to select tools above D20 for existing high-speed machining centers, but they can be selected \u03c6 52\u3001 \u03c6 63 face milling cutter.<\/p>\n\n\n\n
2) General machining center: general application of flying knife series, alloy series. It is not recommended to select tools below D2 and high-speed machining tools for existing common machining centers<\/p>\n\n\n\n
2. Select the tool according to the workpiece material<\/p>\n\n\n\n
1) Graphite electrode: graphite tool<\/p>\n\n\n\n
2) Copper electrode: copper machining tool, high-speed steel tool, alloy tool<\/p>\n\n\n\n
3) Quenching material (above HRC50): carbide coated tools<\/p>\n\n\n\n
3. Select the tool according to the shape of the workpiece to be processed<\/p>\n\n\n\n
When selecting a tool, the size of the tool should be compatible with the surface size of the workpiece to be machined:<\/p>\n\n\n\n
1) End milling cutter is often used to process the peripheral contour of plane parts;<\/p>\n\n\n\n
2) The machining of standard slope profile usually adopts slope cutter;<\/p>\n\n\n\n
3) When milling the plane, the carbide cutter should be selected;<\/p>\n\n\n\n
4) The groove cutter and the rib processing cutter are used for the reinforcement processing;<\/p>\n\n\n\n
5) For some 3D surfaces, you can select FLATE CUTTER, BALL CUTTER, TOROIDAL CUTTER.<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
