How to choose CNC machining tools

The CNC machining center optimizes the selection of CNC machining tools according to the technical status of human-computer interaction technology. The reasonable use of tools and collets should be determined according to the professional processing capabilities of the machining center, the characteristics of the raw materials of the workpiece, the production and processing process, cutting performance and other related factors.

The selection of CNC machining tools is generally: easy and fast installation and adjustment, good bending stiffness, wear resistance and high precision. Starting from the production and processing needs, choose the shorter collet as much as possible to improve the bending stiffness of the tool production and processing. When selecting cutting tools, the specifications and models of the tools should be consistent with the specifications and models of the surface of the commodity workpiece produced. Alloy milling cutters are often used in the production and processing of the peripheral contour of the workpiece in the plane design; when drilling in the plane design, the carbide tool blade turning tool should be selected; when the workpiece is machined with mold seats and grooves, tool steel alloy milling cutters should be selected. ; For the production and processing of the surface of the workpiece or the preliminary processing hole, the corn turning tool with the carbide cutting insert can be selected; when designing the plane profile and the variable inclination angle contour shape, the ball cage, ring, cone and disc car are often selected. Knife.

For the production and processing of any slope, since the top cutter of the ball cage tool has zero durability, in order to ensure the production and processing accuracy, the milling spacing is generally fine, so the ball cage is in the It is more common in the deep processing of slopes. However, since the circular groove cutter is superior to the ball cage cutter in terms of surface production and processing quality and milling efficiency compared with the ball cage cutter, the circular groove cutter should be selected first under the premise of ensuring the cutting accuracy.

In addition, the wear resistance and precision of CNC machining tools have a lot to do with the price of the tool, the most noticeable thing is that in most cases , Although choosing a good tool will increase the cost of the tool, it will in turn improve the production and processing quality and production and processing efficiency, thereby greatly reducing all production and processing costs. In terms of processing management, various types of tools are installed on the CNC tools, and the tool selection and tool change posture are carried out at any time in strict accordance with the regulations. Therefore, using standard collets as much as possible is conducive to quickly and accurately loading standard tools used in drilling, boring, expanding, and drilling into the machine tool spindle or CNC tool. When writing a program, you should master the structure, specification, model, adjustment method and adjustment range of the collet commonly used on the machining center, so as to facilitate the determination of the axial and radial specifications and models of the CNC machining tool.

The above describes the selection method of CNC machining tools. I hope it can help you. If you want to know more about CNC machining, please feel free to consult online. Or call the company's service hotline (upper right corner of the website), we will be happy to provide you with quality service!
