With the wide application of stainless steel materials, it is often encountered in turning, milling, drilling, tapping, etc. However, stainless steel has different characteristics from other materials, so it has become a technician in processing stainless steel. For example, stainless steel knives also contain deep knowledge in stainless steel knives. Today, I will take you to understand the matters that should be paid attention to in the selection process of stainless steel milling knives:
Then the selection of stainless steel milling cutters needs to consider the following factors:
First, the cutting performance of the material of the milling cutter should be considered when choosing a milling cutter.
Second, choose the milling cutter according to the characteristics of the area to be processed. When the workpiece processing allows, we can choose a milling cutter with a larger diameter and a smaller ratio of length to diameter; when we process thin-walled and ultra-thin-walled workpieces, the end edge of the over-center milling cutter should have sufficient centripetal angle , in order to reduce the cutting force of the milling cutter and the cutting part, etc.
Third, we can choose stainless steel milling cutters according to the different processing stages of the workpiece. For example, in the roughing stage, our main purpose is to remove the allowance, then we can choose a large milling cutter with better rigidity, lower precision, and higher chip removal performance. In the semi-finishing and finishing stages, The main thing is to ensure the machining accuracy and product quality of the workpiece. At this time, a finishing milling cutter with high durability and high precision should be selected.
Fourth, when we choose a suitable milling cutter, we try to make the size of the milling cutter fit the surface size of the workpiece to be processed. In actual production, for the peripheral contour processing of plane workpieces, end mills are usually used; when milling planes, carbide milling cutters are preferred; when machining bosses and grooves, high-speed steel end mills are preferred; When rough machining the surface of the blank or the hole, it is recommended to use a corn cutter with carbide inserts; for some three-dimensional profiles and variable bevel contours, use ball end milling cutters, ring cutters, conical milling cutters and disc cutters. More knives.
5. 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 machining accuracy, the cutting line spacing will be very small, so the ball end mill is more suitable for surface finishing. High friendliness. However, end mills have more obvious advantages than ball end mills in terms of surface machining quality and efficiency. Therefore, when ensuring that there is no overcutting phenomenon in workpiece machining, we try to choose end mills when roughing and semi-finishing surfaces. milling cutter.
