The normal use of the ordinary lathe must meet the following conditions: the power voltage fluctuation of the position where the machine tool is located is small, the ambient temperature is lower than 30 degrees, and the relative humidity is less than 80%.
1. Environmental requirements for machine tool location
The position of the machine tool shall be far away from the vibration source, avoid the influence of direct sunlight and thermal radiation, and avoid the influence of humidity and air flow. If there is a vibration source near the machine tool, anti vibration ditch shall be set around the machine tool. Otherwise, it will directly affect the machining accuracy and stability of the machine tool, cause poor contact and failure of electronic components, and affect the reliability of the machine tool.
2. power requirements
Generally, ordinary lathes are installed in machining workshops, which not only have large changes in ambient temperature and poor service conditions, but also have many kinds of electromechanical equipment, resulting in large fluctuations in the power grid. Therefore, the position of installing the ordinary lathe requires strict control of the power supply voltage. The power supply voltage fluctuation must be within the allowable range and remain relatively stable. Otherwise, the normal operation of the NC system will be affected.
3. temperature conditions
The ambient temperature of ordinary lathe is lower than 30 ° C, and the relative temperature is less than 80%. Generally speaking, there is an exhaust fan or cooling fan inside the NC electric control box to keep the working temperature of electronic components, especially the central processing unit, constant or the temperature difference changes very little. Excessive temperature and humidity will reduce the service life of control system components and increase faults. With the increase of temperature and humidity, more dust will bond the integrated circuit board and lead to short circuit.
4. use the machine tool according to the instructions
When using the machine tool, the user is not allowed to change the parameters set by the manufacturer in the control system at will. The setting of these parameters is directly related to the dynamic characteristics of each component of the machine tool. Only the clearance compensation parameter value can be adjusted according to the actual situation.
The user shall not replace the accessories of the machine tool at will, such as using the hydraulic chuck beyond the provisions of the manual. When setting accessories, the manufacturer shall fully consider the matching of various link parameters. Blind replacement leads to mismatching of various link parameters and even unexpected accidents. The pressure of hydraulic chuck, hydraulic tool rest, hydraulic tailstock and hydraulic oil cylinder shall be within the allowable stress range and shall not be increased arbitrarily.
