CNC milling machine how to choose the right tool
CNC milling machine is a kind of widely used machine tool, can process plane, groove, tooth parts, spiral surface and all kinds of curved surface, is developed on the basis of ordinary milling machine. When using CNC milling machine, you need to use a tool, so choose a suitable tool is very important, so how should we choose?
CNC milling machine to choose the general principle of cutting tool: easy installation and adjustment, good reliability, good rigidity, durability and high precision. On the premise of meeting the processing requirements, the tool with shorter handle is selected as far as possible to enhance the rigidity of processing.
First, according to the surface size of the workpiece selection
When selecting a tool, the size of the tool should be adapted to the size of the workpiece being machined. CNC milling machine is used to process the contour of plane parts, often using end milling cutter; Milling plane, should choose carbide blade milling cutter; Processing boss, groove is used high - speed end milling cutter.
Two, according to the workpiece surface shape selection
In mold processing, because the end of the ball cutting tool cutting speed is zero. Therefore, in order to ensure the machining accuracy, the flat cutter is often used. The flat cutter is superior to the ball cutter in surface machining quality and cutting efficiency. Therefore, as long as in the premise of ensuring the cut, whether the surface of the rough machining or finishing, should give priority to flat knife.
Three, reasonable arrangement of the order of cutting tools
In the process of CNC milling machine, due to the tool wear, measurement and replacement for manual manual, take a long time. Therefore, it is necessary to arrange the order of cutting tools properly, usually following the following principles:
1. Concentrated clamping process, coarse and fine cutting tools are used separately
2. First surface processing, and then contour processing
3. Make reasonable use of automatic tool change function of machine tool to improve production efficiency
