The machining center can realize three-axis or more linkage control to ensure that the tool can process complex surfaces. In addition to the linear interpolation and circular interpolation functions, the machining center also has various machining fixed cycles, automatic tool radius compensation, automatic tool length compensation, high-speed CNC machining | machining of machine parts | CNC
machining process graphic display, man-machine Dialogue, automatic fault diagnosis, offline programming and other functions.
Machining centers are developed from CNC milling machines. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes in the tool magazine, the machining tools on the spindle can be changed by an automatic tool changer in a single clamping to achieve multiple machining Features.
The broad meaning of the benchmark is the meaning of "base". The reference in mechanical manufacturing refers to the points, lines, and surfaces used to determine the geometric relationship between geometric elements on the production object. According to different roles and applications, benchmarks can be divided into two categories: design benchmarks and process benchmarks. Process benchmarks can be divided into: process benchmarks, positioning benchmarks, measurement benchmarks, and assembly benchmarks.
High-speed CNC machining technology is a prerequisite to ensure the production of high-quality parts.
On a lathe, the shape and size of the blank are changed by using the rotary motion of the workpiece and the linear or curved motion of the tool, and it is processed to meet the requirements of the drawing.
Ordinary machine tools are increasingly difficult to meet the needs of machining precision parts. At the same time, due to the increase in production levels, the price of CNC machine tools has dropped from time to time. CNC precision parts processing mainly includes ultra-precision turning, mirror grinding and grinding.
The primary premise of CNC precision parts processing is the accuracy of the process benchmark. Computer gong machining | High-speed CNC machining | Machining of machine parts |
The benchmarks on the drawings of CNC machining
machines are all capitalized by A, B, C, D, etc. The circle's datum symbol indicates that when the datum is aligned with the plane and the extension line of the plane or the size limit of the plane, it means that the plane is used as a reference. When the reference mark is aligned with the dimension line, it means that the solid center line of the dimension is used as the reference. I mentioned earlier that the precision of the process is a more general point.
