With the widespread use of stainless steel materials, whether in turning, milling, drilling, tapping and so on will often encounter, but stainless steel has different characteristics from other materials, so in the processing of stainless steel has become a technical staff of a not insignificant problem, for example, the stainless steel tool also implies a relatively deep learning, today the crown drill precision take you to understand the stainless steel milling cutter in the selection process should pay attention to matters.
First, the cutting performance of the milling cutter material should be considered when selecting the milling cutter.
Second, according to the characteristics of the area to be processed to select the milling cutter. In the case of workpiece processing allows us to choose a larger diameter, length to diameter ratio of smaller milling cutters; we are processing thin-walled, ultra-thin-walled class workpiece, over the center of the end edge of the milling cutter should have sufficient centripetal angle, in order to reduce the cutting force of the milling cutter and cutting part, etc..
Third, we can choose the stainless steel milling cutter according to the different processing stages of the workpiece. For example, in the roughing stage, our main purpose is to remove the margin, then we can choose a more rigid, lower precision, chip removal performance of the large milling cutter, to the semi-finishing, finishing stage, the main thing is to ensure the machining accuracy of the workpiece and product quality, then you should choose a higher degree of durability, precision is also higher finishing milling cutter.
Fourth, when we choose the right milling cutter, as far as possible, the size of the milling cutter and the surface size of the workpiece to be machined to fit. In actual production, for the peripheral contour processing of flat workpiece, usually use end mills; in milling plane, carbide milling cutters are preferred; in the processing of tabs and grooves, high-speed steel end mills are preferred; in the processing of rough surface or rough machining of holes, it is recommended to use corn tools with carbide inserts; for some three-dimensional surface and variable bevel contour profile processing, use ball end mills, ring tools, conical Milling cutter and disc-shaped cutter are more.
Fifth, for the processing of free-form surfaces, because the end cutting speed of the ball end mill is zero, at this time, in order to ensure the accuracy of processing, the cutting line distance will be small, so the ball end mill has a high degree of friendliness for surface finishing. However, end mills have more obvious advantages over ball end mills in terms of quality and efficiency of surface machining. Therefore, we try to choose end mills for roughing and semi-finishing of curved surfaces when ensuring that there is no overcutting in workpiece machining.
