Cheap CNC Machine is the gold indexable face milling cutter mainly used for milling plane which is equipped with hard table. When rough milling, the diameter of the milling cutter is selected to be smaller. Because the cutting force is large during rough milling, selecting a small diameter milling cutter can reduce the cutting torque. When the Cheap CNC machine is used for precision milling, the diameter of the milling cutter is selected to be larger. The CNC lathe machine is best to accommodate the entire width of the surface to be processed in order to improve the accuracy and efficiency of adding T. When the machining allowance of the machine tool is large and uneven, the diameter of the tool should be smaller, otherwise, the quality of the workpiece will be affected due to the deep tool mark.
High-speed steel end mills are mostly used for machining bosses and grooves, they are not used for machining the surface of the blank generally because the hardened layer and sand on the surface of the blank will accelerate tool wear.
When machining the rough surface or rough machining hole, you can choose carbide end mill or corn milling cutter for powerful cutting.
When machining the peripheral contour of a flat workpiece, an end mill C is often used.
In order to improve the accuracy of the slot width and reduce the number of tool changes, a milling cutter with a diameter 7 wider than the slot can be used for machining. The middle part of the slot is first milled, and then both sides of the slot are milled using the tool radius compensation function.
When processing three-dimensional curved surfaces or variable beveled contour shapes, ball head milling cutters, ring milling cutters, drum milling cutters, cone milling cutters, disc milling cutters, etc. are often used.
When the machining allowance is small and the surface roughness is high, a face milling cutter with cubic boron nitride inserts or ceramic inserts can be selected to enable high-speed cutting of the cheap CNC machine.
