CNC milling tool of choice to explore

The CNC tool selection is an important factor affecting the CNC machining efficiency and parts processing quality In this paper, based on the analysis of the CNC milling cutter type, structure, diameter, angle, economy and other factors, a reasonable strategy to select the tool. The tool of choice is an important one in the CNC machining process, not only affects the processing efficiency of the machine, but also directly affect the machining quality. CNC machine tool spindle speed and range far higher than the general machine tools, spindle output power greater compared with the traditional method of processing, CNC machining tool put forward higher requirements, including precision, high strength and good rigidity, high durability, and dimensionally stable and easy to install([1]). This tool structure is reasonable, the geometric parameters of standardization, serialization requirements. CNC machine tools with high precision machining, high processing efficiency, fewer processing operations concentrated and parts clamping features, it put forward higher requirements for CNC tool. First the basic requirements of CNC milling better rigidity This is mainly used to improve production efficiency and the need for large cutting parameters, but also to adapt to the CNC milling process is difficult to adjust the characteristics of the cutting parameters. CNC milling cutter durability. Often when a cutter processing, such as tool wear faster, it will affect the surface quality and machining accuracy of the workpiece, and will increase the tool change due to adjust the number of the knife and the knife will also work left on the surface due to the joint cutter step formed on the knife error, reducing the quality of the surface of the workpiece. In short, according to the heat-treated condition of the workpiece material, cutting performance and allowance, choose good rigidity, high durability cutter, give full play to the productivity of CNC milling and get satisfied with the quality of processing premise([2]).
