In the free-form surface machining, because the end cutting speed of the ball end milling cutter is zero, therefore, in order to ensure the machining accuracy, the ball end milling cutter with small row spacing is generally used to finish the surface. But whether the surface processing quality or processing efficiency are far better than the ball end milling cutter, so, CNC machine tool sales in the premise of ensuring the processing accuracy of parts, in the rough, semi-precision surface processing, should try to choose the end milling cutter.

The "you get what you pay for" principle is embodied in knives. The durability and precision of tools have a great relationship with the price of tools. In most cases, the choice of good tools by enterprises will increase the cost of tools, but the resulting improvement of processing quality and efficiency will greatly reduce the overall processing cost. Of course, the production of CNC machine tools in the processing, in order to let the value of the tool to get greater play, but also need to "hard and soft combination", that is, the selection of high quality processing programming software to cooperate.

All the tools in the machining center are loaded into the tool library in advance and the corresponding tool change action is completed through the instruction of tool selection and tool change in the numerical control program. Therefore, it is necessary to choose the corresponding standard tool handle in line with the specifications of the machine tool system, so as to make the CNC machining tools quickly and accurately professional CNC machine tool installed on the spindle of the machine tool or back to the tool library.

Through the above explanation, I believe that we must have a deeper understanding of the choice of machine tools. Work to do a good job must first benefit its tool, now there are a wide variety of tools on the market, the quality is also uneven, users want to choose their own tools, but also need to consider carefully.
