The Three Positions Principle of NC Machine Tool Maintenance
NC machine tool play an important role in manufacturing and automation industry, when it became malfunction, NC machine tool maintenance should be carried out timely in order to keep the normal use . NC machine tools are complex in structure, easy to damage, and its maintenance should strictly following the Three Positions Principle.
First, the position of an object must be precisely referred to the NC machine tool, for example, in the process of maintenance and repair, the reference coordinate system should be established and it must be consistent with the machine tool coordinate system. The position should be measure frequently throughout the process and needed to check against the original data at any time. During the repair process, the machine should move to certain position and it should be moved back to the original position when needed, in order to ensure the machine to return to the factory specifications.
Second, the storage position of the spare parts must be clearly specified, in order to avoid confusion. At the store position of the spare parts, there should be a standardize storage place, which allows the operator to identify and select easily. In addition to that, the operation should keep the spare parts in order, so the access and operation will be smooth.
Third, the combination of parts should be precisely confirmed. After the spare parts are replaced, the combination of parts should be fully tested, the coordinate position of faulty parts must be identified and the relative relationships of parts should be accurately confirmed.. After all the tests, the replacement of parts can be confirmed.
In order to ensure the normal operation of NC machine tool, the maintenance must strictly following the Three Positions Principle , which is described above. In addition to that, operation should read the manual carefully before the operation, so that everyone understand the components and function of machine tool well and create an efficient operation environment for maintenance. The Three Positions Principle of NC machine tool maintenance is the basic procedure of machine tool maintenance, it must be fully followed in order to improve the security and efficient of machine tool maintenance.
In conclusion, NC machine tools is important equipment in automation industry, it requires strict maintenance procedures in order to ensure the effective use of equipment. Among the procedures, the Three Positions Principle is of great importance, it provide a procedure for maintenance and help them achieved an effective maintenance for their NC machine tools.
