Bridge coordinate measuring machine is one of the most commonly used coordinate measuring equipment at present, and its granite bed is one of its important components. This kind of bed material has high hardness, easy deformation, good thermal stability and strong wear resistance, making it the preferred material for high-precision measurement. Although granite bed has many advantages, but its common problems and failures are inevitable, here we for some common problems and solutions for a simple summary and introduction.
1. Wear and tear on the bed
The surface of granite bed is durable, but the erosion effect of collision and vibration on the bed can not be ignored after a long time of use. Focus on observing the surface wear of the CMM bed to check flatness, edge damage, and corner damage, which may affect the accuracy and reliability of the bed. In order to avoid the loss caused by wear and tear, the bed must be standardized in the early use of the operation, reduce unnecessary impact and friction, in order to extend the service life of the bed. At the same time, it is best to carry out regular maintenance according to the specific situation after the use of CMM, to prevent excessive wear of the bed and improve the service life.
2. The bed is deformed
Due to the different use environment of CMM, the loading state of the bed will be different, and the bed is prone to deformation under long-term low-cycle load. It is necessary to discover and identify the deformation problem of the bed in time, and solve other related technical problems simultaneously to fully meet the needs of CNC measurement and even production. When the bed deformation problem is obvious, it is necessary to reconstruct the vertex correction and the calibration of the machine to ensure the accuracy of the measurement results.
3. Clean the bed surface
A long time of use will produce a variety of dust and dirt on the surface of the bed, which has a negative impact on the measurement. Therefore, it is necessary to clean the surface of the bed in time to maintain the smoothness of its surface. When cleaning, some professional cleaning agents can be used to avoid the use of scrapers and hard objects; The protective cover on the surface of the bed can play a role in protecting the bed.
4. Maintenance adjustment
In a period of time, due to the use of equipment will lead to the performance loss of some parts or electrical components, mechanical deformation, common maintenance parts loose, etc., which need to be adjusted and maintained in time. It is necessary to maintain the accuracy and reliability of the CMM bed to ensure its long-term stable operation and accurate measurement data output. For small problems can be directly judged to solve, for larger problems need to be handed over to professional technicians for maintenance.
The above is about the introduction of common fault problems of the bridge CMM granite bed, but in general, the service life and stability of the bridge CMM are relatively long, as long as we can find problems in time and do a good job of maintenance, we can play a better effect in the work and improve work efficiency. Therefore, we should take the use of CMM seriously, strengthen the daily maintenance of equipment, ensure its high precision, high reliability of the stable performance, to provide a stable and reliable guarantee for the technological innovation and development of enterprises.
