After buying CNC machine should make full use of, especially put into use in the first year, make it easy to fail the weak link of exposed as soon as possible, be in the warranty period to eliminate. Processing, reduce the opening and closing of nc machine tool spindle, as far as possible to reduce the wear of the clutch, gear and other components.
No processing task, nc machine tools are regularly electricity, it is better to live 1 ~ 2 times per week, every time an empty running 1 hour or so, to take advantage of the machine tool itself calorific value to reduce the humidity inside the machine, make the electronic components shall not be affected with damp be affected with damp, at the same time can also be found in a timely manner for battery power shortage alarm, to prevent the loss of the system setting parameter.
Nc equipment preventive maintenance, is must pay attention to the possible cause equipment failure and the failure factors is difficult to solve after elimination before failure. Generally speaking should include: equipment type selection, the proper use of equipment and operation of the circuit check.
(1) from the standpoint of maintenance, nc equipment selection
In equipment selection research, in addition to equipment availability parameters, its serviceable life parameters should include: equipment advanced technical indexes, reliability and maintainability. Advanced refers to equipment must have technical content of the development level of age; Reliability refers to the mean time between failures, mean equipment failure rate, especially the control system is through the national authoritative organization for inspection of the inspection, etc.; Maintainability refers to whether it is convenient for maintenance, spare parts if there is a good market space, whether all the maintenance technology data is complete, if there is if a good after-sales service, maintenance technical ability and equipment performance/cost ratio is reasonable, etc.
Here, special attention should be paid to the integrity of the drawings, backup system disk transmission, PLC program software, system software, transmission means, operating password, etc., be short of one cannot.
Technical training on the use of party cannot go through the motions, all of these must indicate in the contract after order, and seriously implement, otherwise will bring future trouble to the following job. In addition, if not special circumstances, try to choose the same of the same series of CNC system, in this way, the spare parts, drawings, data. Programming, operation is good, also is advantageous to the management and maintenance of the equipment.
(2) adhere to the proper use of equipment
Proper use of numerical control equipment is the key to reduce the equipment failure and prolong service life, it occupies very important position in the preventive maintenance. According to statistics, about one-third of the fault are man-made, and general maintenance (pours oil, cleaning, inspection, etc.) was conducted by the operator, the solution is: emphasis on equipment management, use and maintenance of consciousness, strengthen the business, technical training, improve the quality of operation personnel and make them grasp characteristics of machine tool as soon as possible, strictly carry out operation procedures and equipment maintenance procedures, ensure the equipment running in proper working condition.
(3) adhere to the Tours of inspection equipment operation
According to the numerical control equipment advanced, the characteristics of high complexity and intelligent makes it maintenance, maintenance work more complex and require higher than ordinary equipment. Maintenance personnel should through the regular inspection tour, such as the fan operation of CNC system, cabinets, electrical heating, whether there is abnormal sound or smell, pressure gauge indicates whether normal, each line and joint leaks, lubrication conditions are in good condition, etc., completes the failure and accident prevention, if discover tbnoabnormal should be resolved in a timely manner, to do so is likely to wipe out fault in a fledgling state, which can decrease the loss of all can be avoided.
