Preventive maintenance is an important and positive factor in the daily management of digital control plasma processing equipment. As the name suggests, active maintenance is to minimize or delay the failure of digital control equipment by solving the factors that may lead to equipment failure and the factors that are difficult to solve before failure.

1.正确使用设备

1. Use the equipment correctly

数控等离子加工设备在预防性维修中发挥着重要作用，可减少设备故障，并在使用得当时延长使用寿命。根据监督厅的统计，三分之一的故障是人为和一般维修(如注油、清洁、检查等)造成的。)由运算符完成。解决办法是:重视提高对设备管理、操作和维护的认识，加强操作、技术培训，提高操作人员的素质，使其尽快掌握设备性能——工具，严格执行设备操作和维护规则，并确保

NC plasma processing equipment plays an important role in preventive maintenance, which can reduce equipment faults and prolong service life when used properly. According to the statistics of OIOS, one third of the failures are caused by human and general maintenance (such as oiling, cleaning, inspection, etc.) Completed by operator. The solution is: pay attention to improving the understanding of equipment management, operation and maintenance, strengthen operation and technical training, improve the quality of operators, make them master equipment performance tools as soon as possible, strictly implement equipment operation and maintenance rules, and ensure

2.操作员日常检查

2. Daily inspection of operators

操作员是数字控制等离子加工设备的直接用户。为保证数控加工设备的正常运行，数控操作人员需要每天执行以下任务:检查所有防护板、外壳和门操作是否合适，全程沿每条轴行走，观察操作是否平稳， 确保所有轴的限制器正常工作并适应相应的限制器位置，检查导轨上是否有划痕或磨损迹象，检查导轨清洁器是否损坏，以及是否应接触导轨以便

The operator is the direct user of digitally controlled plasma processing equipment. In order to ensure the normal operation of NC processing equipment, NC operators need to perform the following tasks every day: check whether all protective plates, shells and doors are operated properly, walk along each axis in the whole process, observe whether the operation is stable, ensure that the limiters of all axes work normally and adapt to the corresponding limiter positions, and check whether there are scratches or signs of wear on the guide rail, Check whether the guide rail cleaner is damaged and whether it should contact the guide rail for

根据数控等离子加工设备的、复杂和高智能特点，维修和保养要比普通设备复杂得多，要求也高得多。维修人员应通过定期的机动检查积极预防故障和事故，如数控系统排气风扇的运行、机柜的热、电机的存在异常噪音或外来气味、压力表的指示、泄漏、所有管路良好的润滑条件等如果发现异常现象，可以在胚胎状态下加以解决，以减少所有可避免的损失。

According to the advanced, complex and intelligent characteristics of NC plasma processing equipment, the repair and maintenance are much more complex and demanding than ordinary equipment. Maintenance personnel shall actively prevent faults and accidents through regular mobile inspection, such as the operation of exhaust fan of CNC system, heat of cabinet, abnormal noise or foreign smell of motor, indication of pressure gauge, leakage, good lubrication conditions of all pipelines, etc. if abnormal phenomena are found, they can be solved in embryonic state to reduce all avoidable losses.
