How to better reflect the high precision machining performance of CNC machine tools?

Compared with ordinary machine tools, CNC machine tools have more electronic components and are more precise, so the requirements for the location, temperature, and power supply for installation and use are more stringent.

The requirements for the installation position of CNC machine tools

First of all, the location of the CNC machine tool should be far away from the source of vibration, avoid direct sunlight and heat radiation, and avoid the impact of humidity and airflow. If there is a vibration source near the machine tool, an anti-vibration trench should be set around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, and cause poor contact of electronic components, failures, and affect the reliability of the machine tool. Enterprises with conditions should place the use of CNC machine tools in an air-conditioned environment as much as possible, and maintain a constant room temperature. The more expensive the machine tool, the more it should be used in an air-conditioned room to avoid unnecessary loss of accuracy.

The requirements of CNC machine tools for ambient temperature

Due to the large differences between the north and the south of our country, and machine tools have relatively high requirements for ambient temperature, generally speaking, exhaust fans or air coolers are installed in the electrical boxes of CNC machine tools to maintain the electronic components, especially the central processing unit. The working temperature is constant or the temperature change is small. However, this is still not enough to guarantee the accuracy loss of the machine tool during processing, because the machine tool will generate excessively high temperature during the processing process, which will cause the life of the control system components of the CNC machine tool to be reduced. The increase in temperature and humidity will also increase dust and cause adhesion on the integrated circuit board, leading to short circuits and machine failures. Therefore, it is better to ensure a constant environment around the machine tool. In addition to temperature, the CNC machine tool should not be placed in a place with corrosive gas. If the electronic components are corroded by the corrosive gas and the system is short-circuited, the serious consequences can be imagined.

The requirements of CNC machine tools for power supply

CNC machine tools need electricity to operate the equipment, and companies that generally use CNC machine tools for processing often do not have only one piece of equipment. If there are more equipment, when they are used at the same time, the power grid will fluctuate greatly, which will affect the processing effect. Therefore, when installing a CNC machine tool, you must strictly control and select the power supply used. Only by controlling the voltage fluctuation within a safe and stable range can it not affect the machine tool processing and the normal operation of the CNC system.

Specifications for the use of CNC machine tools

When using CNC machine tools, you must strictly follow the standards and parameters set by the manufacturer. This is the same as taking medicine when you are sick. To eat six capsules at a time, six times a day, it will definitely have a bad effect on the body. When operating the machine tool, the user cannot replace the machine tool accessories at will, such as using a hydraulic chuck that exceeds the specifications in the manual. When setting up accessories, the manufacturer fully considers the matching of various link parameters. Blind replacement causes mismatch of various link parameters, and even causes unexpected accidents. The pressure of the hydraulic chuck, hydraulic tool rest, hydraulic tailstock, and hydraulic cylinder should be within the allowable stress range, and any increase is not allowed, otherwise safety accidents will easily occur.

Nowadays, the use of CNC machine tools in China has become more popular. With the increase of users' requirements for automation, it is believed that the sales of CNC machine tools will continue to increase. In order to better enable the CNC machine tool to exert its high-precision processing capabilities, the above requirements must be kept in mind.
