Milling cutter is to be used at what milling machines, those who have one or more tooth rotate cutting tool. Each tooth is ordinal when the job the surplus that cuts work by fits. Milling cutter basically is used on milling machine to machine planar, step, groove, figuration the surface and cut off workpiece to wait.
Choose milling cutter cutter hub and tool carrier what to point note?
1, above all, when choosing a milling cutter, want to consider its tine number. For example the diameter has 6 a tooth-like part of anything only for the thick tine milling cutter of 100mm, and the diameter can have 8 a tooth-like part of anything however for the close tine milling cutter of 100mm. The decision of old young general of pitch shares the tooth number of cutting at the same time when milling, the smooth stability that affects cutting and cut the demand of rate to the machine tool. Manufacturer of production of every milling cutter has series of milling cutter of the thick tine of itself, close tooth flank.
2, thick tine milling cutter is multi-purpose at rough machining, because it has the bigger chamfer that hold bit. If look bits chamfer is insufficient big, will cause a bits difficulty or cut aggravate of attrition of bits and cutter hub, workpiece. Below same feed speed, thick tine milling cutter bear of every tine cutting ages milling cutter wants more closely big.
3, deepness of the cutting when mill of essence of life is more shallow, it is 0.25 ～ 0.64mm commonly, the cutting negative charge of every tine is small (0.15mm of about 0.05 ～ ) , what need power not quite, can choose close tine milling cutter, and can choose bigger feed. Because mill of essence of life is medium,metallic excision rate always is finite, somes chamfer of bits of look of close tine milling cutter is small also just as well.
4, the main shaft with bigger to taper hole norms, better tigidity, also can have thick mill with close tine milling cutter. Because age milling cutter has more tine to participate in cutting at the same time closely, should use bigger cutting deepness (1.27 ～ 5mm) when, want to notice whether machine tool power and tigidity are enough, chamfer of bits of milling cutter look is enough big. The circumstance that discharge bits needs experiment test and verify, if discharge bits to have a problem, answer to adjust cutting dosage in time.
5, when undertaking weighing bear thick mill, the machine tool that too great cutting power can make tigidity poorer arises brace up quiver. This kind brace up quiver the collapse blade that can bring about hard alloy razor blade, shorten thereby cutting tool life. It is OK to choose thick tine milling cutter the bring down requirement to machine tool power. So, when norms of main shaft aperture is lesser (be like R-8, 30 taper hole) , can undertake with thick tine milling cutter milling is machined effectively.
