Ultrafine grinding installation, after going through the test phase, put into the production process, does not mean that you can smoothly carry out the production, but also to experience the run-in period, such as our new car, but also to run through the trial period, to be more Good use, ultrafine mill, it is in the run-in stage, the internal parts will be worn, this time is prone to failure, the need for a lot of attention to production anomalies, if you find abnormal The situation, the need for timely shutdown for processing, here is to introduce what needs attention in the run-in period of the problem.

1, wear fast: Ultrafine grinding due to new equipment parts processing, assembly and adjustment and other factors, the friction surface roughness, with a smaller contact surface area, the surface of the uneven pressure conditions in the operation, the parts The concave and convex parts of the surface are mutually embedded and rubbed with each other, and the metal scraps falling down are also used as abrasives to further participate in the friction and speed up the wear of the parts' mating surfaces. Therefore, the parts (especially the mating surfaces) Wear, wear fast. At this time, if the work overload, it may cause damage to parts, resulting in early failure, in view of this phenomenon, we can not avoid the normal wear and tear, but the workload can be controlled so that the wear and tear occurs in a controlled Within

2, poor lubrication: Ultrafine grinding parts due to the assembly of smaller clearances, and due to assembly and other reasons, it is difficult to ensure uniformity with the gap, the lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to Prevent wear and tear, thereby reducing the lubricating performance, causing the early abnormal wear and tear of the workpiece, resulting in serious friction or scratch with the friction phenomenon, resulting in the occurrence of failure;

ultrafine mill

3, Leakage: Ultrafine grinding due to loose parts, vibration and machine heat, the sealing surface of the machine and the pipe joints, etc., there will be leakage, part of casting, machining and other defects, difficult to find in the assembly and debugging , But due to the vibration and impact during the operation, the defect is exposed and appears as leakage oil (water). Therefore, it is normal phenomenon that the leakage occurs during the running-in period. However, To prevent its impact on production, we need to pay more attention to this phenomenon of leakage and reduce the problems that may arise.

4, many mistakes: Because of the structure of the Ultrafine grinding, performance is not enough (especially the new operator), easy to malfunction due to failure, or even cause mechanical accidents, so put into production before the need for staff Reasonable training to make it a more comprehensive understanding of the structure of the machine in order to be able to find problems at any time to solve, the other to strengthen the lubrication, do not overload the work, check whether the parts are loose, and tighten the parts, at the same time to be correct Operating machinery and equipment to avoid causing unpleasant consequences;

The article introduces the superfine grinding in the run-in period need to pay attention to the problem, the above is mainly through four aspects of the analysis, we in the actual production process, the run-in phase must pay more attention to these aspects, reduce this stage Ken The impact that can emerge on production and life expectancy, so that the machine better into the production process.
