1. Reasonably determine the main parameters of the machine tool.
There are many main parameters of CNC machine tools, such as the maximum rotary diameter, the maximum processing diameter, the maximum processing length, the number of tool holder tool positions, the power of the main motor, the configuration of the CNC system, the positioning and repeated positioning accuracy of the machine tool, etc.
Users need to determine the specifications and models of the purchased machine tools according to the length and diameter of their own processed parts, and compare the main parameters of the machine tool.
2. Selection of CNC system. When choosing a CNC system, there are several factors to consider, accuracy, price, and convenience of operation.
For the accuracy, the servo numerical control system has a higher precision, and the stepper numerical control system has a slightly lower accuracy, but in recent years, the machine tool manufacturers have widely used the servo numerical control system, which can meet the requirements for the processing of general parts, and the parts with high precision requirements can be equipped with a high-precision numerical control system and increase the position sensor in the X and Z axes, which can be customized to the manufacturing plant.
3. Appearance protection of CNC machine tools. The appearance protection of general CNC machine tools is divided into full protection and semi-protection.
The full protection shape is generous and beautiful, but the dimensions are larger than the same specifications of the semi-protection machine tool, the full protection of various safety signs is also more clear and eye-catching, the leakage design of various oil and water is also considered more detailed, and the safety performance is higher, and the semi-protection is limited to the structure, in the oil-proof, waterproof, leak-proof and safety performance is poorer, but the general full protection price is also higher than the semi-protection machine tool, so the user should choose reasonably according to the specific situation.
4. Noise of CNC machine tools.
CNC machine tool noise is a more important indicator, the national standard stipulates that the noise of the general machine tool shall not exceed 83 decibels, and the sound shall not have obvious impact and vibration, of course, the lower the sound of the whole machine, the better, the user can listen to the sound at low speed, medium speed and high speed when purchasing machine tools
