How to maintain the grinding accuracy of CNC roll grinder?
CNC roll grinding machine is an important machine of roll processing. The accuracy is the important of roll grinding machine. The quality of the product is related to the quality of the roll. Therefore, many steel mills and roll manufacturers have spent a lot of money to buy CNC roll grinders from Europe. A high-precision roll grinder is the key to processing rolls, but how to maintain the accuracy of a high-precision CNC roll grinder for a long time is more important. The roll grinder is only a key component for processing high-precision products, not all of them, so how can the precision of the roll grinder not reduced for a long time?
The top is the core part of the grinder. Whether the disassembly and assembly is standardized determines the accuracy and life of the grinder. The movement of the tailstock and the expansion and contraction of the sleeve also have a great influence on the accuracy of roll grinding machine. People are the center of the whole event. In order to maintain the high precision of the machine tool for a long time, we have summarized the management methods to maintain the long-life precision of the roll grinding machine:
1. Tightening of top bolts:
1.1. Screw on the bolts by hand in a diagonal manner.
1.2. Use a torque wrench to tighten step by step in a diagonal manner.
1.3. After the top is tightened, the rotation accuracy (runout) should be checked. If the rotation accuracy exceeds the standard, the reason should be checked. If the reason is not found out, it cannot continue to be used.
Regularly carry out spot checks and fixed repairs on the pressure, precision, lubrication, etc. For example, is the grinding wheel spindle in good condition? Is the spindle oil pressure normal? The grease of each part is replaced regularly; the positioning accuracy of the X and Z axes, the repeat positioning accuracy, and whether the backlash is within the national standard or the required range, etc.
