目前,刀具行业生产大量各式各样的镶片铣刀,这种铣刀是由合金结构钢40X或者50XφA制成的刀体和用机械方法固定在刀体槽中的硬质合金可转位刀片组合而成的.为了提高刀体的使用寿命,通常要对其进行各种热处理或化学热处理(氮化、碳氮共渗等),以使其整体或局部强化到规定的硬度值.镶片铣刀刀体的现有制造方法是:通过机械加工来获得给定形状和尺寸的刀体;强化—油淬,再在T=425～525℃下回火到所要求的硬度HRC28～30.在这种工艺中,没有安排刀片槽的磨削加工工序.但是在制造形装复杂的刀体时,由于对各部分位置精度要求很高,所以刀片槽在热处理后都要磨削,以便消除由于淬火和回火引起的变形.
At present, the tooling industry produces a large variety of insert milling cutters, which are made of alloy steel 40X or 50XφA, and carbide that is mechanically fixed in the tool pocket Blade combination.In order to improve the service life of the knife body, usually it should be a variety of heat treatment or chemical heat treatment (nitriding, carbonitriding, etc.), so that the overall or local strengthening to the specified hardness value Existing methods of sheet cutter body fabrication include: obtaining a body of a given shape and size by machining; strengthening-oil quenching followed by tempering to a desired hardness of HRC 28-30 at T = 425-525 ° C In this kind of process, there is no arrangement of the blade groove grinding process.But in the complex shape of the cutter body, due to the high precision of the position of each part, the blade groove after heat treatment must be grinding, so that Elimination of deformation due to quenching and tempering.
