Machining center tools are mainly divided into two categories: milling tools and hole cutting tools.
The selection of milling tool is mainly the selection of milling cutter type and milling cutter size.
The type of milling cutter should be adapted to the surface shape and size of the workpiece.
Face milling cutters should be selected for machining larger planes; end milling cutters should be selected for machining grooves or smaller steps and plane contours; ball-end milling cutters should be selected for machining curved surfaces; die milling cutters should be used for machining mold cavity or punch forming surface; for machining closed keyways, keyway milling cutters should be used; drum milling cutters should be used for processing variable bevel faces; forming milling cutters should be used for processing all kinds of straight or arc-shaped grooves, bevel faces, special holes, etc.
When rough milling or milling unimportant machining planes, coarse tooth milling cutters can be used; when finishing milling, dense tooth milling cutters can be selected to achieve low surface roughness with a small feed; when milling hard metal, dense tooth milling cutters must be selected and the feed should be small to prevent vibration.
The size of the milling cutter should also be adapted to the surface size and shape of the machined workpiece.
The selection of tool diameter mainly depends on the specification of the equipment and the machining size of the workpiece, and the required power of the tool should be within the power range of the machine tool.
Rough milling cutter diameter should be smaller, finishing milling cutter diameter should be as large as possible, it is best to be able to contain the entire machining width.
When the surface requirements are high, you can also choose to use a blade with a polishing effect.
