Different CNC milling machine processing mode


Small CNC milling machine is a high-precision, high-efficiency processing equipment, and its processing form and processing capability have been essentially different from ordinary processing equipment. First of all, its processing process is no longer like the traditional processing equipment. It requires the first-line operation staff to control the machine without interruption. The entire workpiece processing of the small-scale CNC milling machine is automatically completed under the control of the CNC system as the first-line processing personnel. Just before processing, according to the drawings and process requirements, a reasonable processing program and a reasonable machining tool are prepared, and then the corresponding machining tool can be replaced after the workpiece has completed a process. It can be said that the entire machining process of the workpiece does not require processing personnel. Actually control the machine, so that its processing process and the traditional processing mode has a fundamental difference.

 

The machining accuracy of the small CNC milling machine can not be compared with the traditional processing equipment, because the transmission mechanism is no longer using the traditional gear transmission mechanism with the T-screw, but instead the servo control system drives the high speed. In the form of a ball screw, don't underestimate this small change, it can bring about the quality of the workpiece processing accuracy changes.

 

The positioning precision and repeatability of small-sized CNC milling machines can reach within 0.01mm, and the high-precision machining of workpieces can be completed. However, the machining precision and processing capability of the machine tool are only part of the hardware. The final machining accuracy of the workpiece is also affected by many factors such as the tool, its own reason, and the processing technology. We have unified the cause of the workpiece machining beyond the processing machine itself. As an objective factor, in simple terms, the objective factors that cause the workpiece to be out of tolerance are stress errors in the workpiece, self-deformation due to machining processes, and thermal deformation errors.
