According to the technical state of human-computer interaction technology, the CNC machining center optimizes the selection of CNC machining tools. 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 material of the workpiece, the process of production and processing, cutting performance and other related factors.
The selection of CNC machining tools is generally: convenient and quick installation and adjustment, good bending stiffness, wear resistance, and high precision. Starting from the needs of production and processing, choose a shorter collet as much as possible to improve the bending rigidity of the tool production and processing. When selecting cutting tools, the specifications of the tool should be consistent with the specifications of the surface of the workpiece to be produced. Alloy milling cutters are often used for the production and processing of the peripheral contour of the workpiece on the graphic design drawing; when drilling the graphic design drawing, you should choose a carbide tool blade turning tool; when processing the mold seat and groove on the workpiece, you should choose a tool steel alloy milling cutter ; For the production and processing of the surface of the workpiece or the initial machining hole, you can choose the corn turning tool inlaid with carbide tool blades; when designing the planar surface and variable inclination angle outline, you often choose ball cage, ring, cone and disc turning tools Knife.
For the production and processing of any slope, because the durability of the top knife of the ball cage tool is zero, in order to ensure the production and processing accuracy, the milling line spacing is generally close, so the ball cage is more common in the deep processing of the slope. However, compared with the ball cage cutter, the circular groove cutter is superior to the ball cage cutter in terms of surface production and processing quality and milling efficiency. Therefore, under the premise of ensuring cutting accuracy, the circular groove cutter should be selected first.
In addition, the wear resistance and precision of CNC machining tools have a great relationship with the price of the tool. The most noticeable thing is that in most cases, choosing a good tool will increase the cost of the tool, but in turn will increase the cost of the tool. Improve processing quality and processing efficiency, thereby greatly reducing all processing costs. In terms of processing management, all kinds of tools are installed on the CNC tools respectively, and the tool selection and tool change postures are carried out in strict accordance with the regulations at any time. Therefore, using standard collets as much as possible is conducive to quickly and accurately loading standard tools used in drilling, boring, expanding, drilling and other processing processes into machine tool spindles or CNC tools. When writing the program, you should master the structural specifications, adjustment methods and adjustment ranges of the commonly used collets on the machining center, so as to facilitate the determination of the axial and radial specifications of the CNC machining tools.
