CNC Maintenance in Tehran
According to the progress of technology and industry, the maintenance of CNC machine is the duty of people who work in the production departments of factories and different industries, who are responsible for the installation, commissioning, operation and maintenance service of the equipment. . The production capacity and type of machines, especially CNC systems, have become very different from the past, and due to the increase in investments made in this field, the need for maintenance and repairs (to provide support services to industrial centers) is widely raised. has been
Importance of CNC Maintenance Maintenance System
Nowadays, factories that want to plan production, must have a precise and regular maintenance and repair method. Because otherwise, the production flow may be stopped at any moment due to the breakdown and sudden failure of various machines and devices. In addition to the direct costs of providing spare parts and repair workers' wages, technical defects and machine stoppages impose a lot of financial losses on the factory's economy. While the existence of an organized and organized CNC machine maintenance system reduces the worry of managers and supervisors about the sudden stoppage and idleness of machines and people, and creates more confidence to take advantage of activities.
Benefits of CNC Maintenance System
Managers of various industrial units are interested in creating a proper maintenance and repair system for the machines and equipment of their covered complex for many reasons. Some of the most important reasons for CNC machine maintenance are as follows:
Ordering the normal flow of production activities and preventing stoppage of operations and reduction of efficiency
Preservation of material capital, including devices and machines in the factory, in order to use them longer in the production process.
Creating better safety and care conditions for employees and reducing the number of accidents and accidents caused by working with defective machines and equipment.
Lowering the costs caused by frequent repairs and successive breakdowns of equipment as a result of neglecting them.
Increasing the useful life of devices and reducing their depreciation, breakdown and wear and tear and by saving the use of machines and equipment. In the factory, in addition to the mentioned cases, the existence of maintenance and repair systems in the factories allows the factory managers to make an accurate evaluation of the work of the machines and equipments that have been purchased for different applications and different types Compare them, which are offered by manufacturers of different countries, in the real field of work. And when the working quality of the machines in question is not satisfied in terms of maintenance and repair, they should use better quality machines to meet their future needs.
CNC Maintenance Maintenance Instructions
CNC machines need to be taken care of and follow the principles of maintenance so that the possibility of their damage or failure is reduced or delayed. Therefore, some of the CNC machine maintenance instructions are summarized by examining its different parts:
A. Spindle motor:
B. Z and X -axis engines
These engines are designed for minimal maintenance operations, but it is necessary to review and control them continuously in terms of sound and cleanliness.
C. Spindle motor belt:
Avoid cleaning the belt with agents soaked in grease. Excellent performance and long life for the belt is achieved by observing the following points.
The cam belt profile and pulleys should be clean.
The belt is properly tensioned. (Explanation that if the belt between two pulleys is under tension too much, it will increase the preload on the bearings and lead to a decrease in transmission power and increase in noise, and even on the contrary, if the belt is loose, it will lead to head over a long period of time. Eating the belt will eventually cause the belt and pulley to heat up and wear the belt, which will reduce the life of the belt.
The poles are mounted parallel to each other. (Minimum non-parallel value of the money: one millimeter)
After every 500 working hours, check the wear of the belt and the tension force of the belt.
D. Central lubrication unit:
The task of the central lubrication unit is to lubricate the surfaces of Z and X axes, ball screw bearings, Z and X axes, and ball bearings. The following are considered:
Oil level and pressure should be checked daily with iodine.
The pump suction filter should be cleaned every 2000 hours.
Lubrication intervals: 10 minutes and approximate consumption for 10 working hours: 13 liters.
E. Hydraulic unit:
The duty of the hydraulic unit is to supply the oil pressure and flow required for the locking and releasing system of the three systems and to supply the power from the bird to the work piece.
The necessary pressures for locking the three systems and the force of the bird's axis can be adjusted by pressure reducing valves based on the work piece manufacturing technology.
The oil level should be checked daily.
The type of filter in the return path is 10 micron mesh, which must be replaced every six months.
The filter in the suction path of the pump can also be cleaned.
C. Three systems:
Q. Tart:
There is no need to charge or change the tart oil. In case of complete disassembly, pour oil through this channel before assembling the solenoid equipment.
Due to the use of electronic and electrical equipment such as encoder and motor, the tart's sensitivity to soapy water leakage is very high, so replace the casket if necessary.
Tips on maintenance of the CNC device
The points that must be observed during the maintenance of the CNC machine are as follows:
