What is the treatment method of common problems of automatic double-end grinding machine
Full-automatic double-end grinding machineHow to deal with common problems
The grinding extrusion problem of automatic double-end grinding machine is the process of extrusion, sliding, ploughing and chip separation of grinding particles on the surface of the workpiece. The whole process is accompanied by the friction of the abrasive particles on the surface of the workpiece, especially in the double-sided grinding process. The grinding area is large, the friction resistance becomes larger, the friction heat also becomes larger, and the high temperature is easily generated. The high temperature generated by friction is also concentrated in the place where the fragments gather, causing the local metal structure on the surface of the workpiece to anneal and shrink, forming a concave shape, and the surface color turns purple, causing grinding damage.
Full-automatic double-end grinding machineThe key to solve the grinding damage is to choose a suitable grinding wheel. The grinding wheel must have its own appropriate hardness, which can not be lost too fast, but also has a strong self-sharpening to reduce the friction resistance in the grinding process. The second is that the grinding wheel should have a good chip removal performance, and the second is that the cutting fluid should make full use of the good cooling system effect of the students. In addition, if the grinding technology is only slightly damaged, it can be properly and effectively reduce the speed of the grinding wheel, reduce the cutting force, and solve the problems related to the damage of the workpiece. The taper of the workpiece can be adjusted under the guidance of the machine tool, or a layer of waterproof paper can be coated on the wheel surface release plate to check whether the guide wheel bearing is too loose. Automatic double-sided grinding machine: There are many reasons for the collapse of the cutting edge, which are related to the grinding angle of the relative position of the substrate, the reference wheel, the guide plate and the grinding wheel. First, the grinding angle of the grinding wheel as described above is checked and adjusted to avoid the concentration of the grinding amount on a certain part of the grinding wheel during the grinding process and to maintain the uniformity of the grinding force when the workpiece is ground by the grinding wheel. In order to achieve the purpose of grading grinding.
Secondly, check the parallelism between the reference plate and the right wheel and the height difference between them. Adjust the appropriate gap between the inner and outer guide plates of the base plate so that the workpiece can pass freely without interference, and at the same time ensure that it is not skewed. In addition, the position of the reference wheel is also very important, and it is necessary to check the surface flatness of the grinding wheel. Since the linear speed of the grinding wheel from the outer edge to the center gradually drops to zero, the outer edge consumes quickly and is easy to protrude, so the grinding wheel needs to be trimmed to maintain surface flatness. The difference in surface finish of the grinding part of the full-automatic double-face grinder may be caused by the following factors: the middle height of the grinding part is low, the grinding area of the grinding part is small, the grinding wheel jitter is too large, the quality of the guide wheel is low, The grinding speed of the grinding part is high, and the surface of the grinding fluid is greasy or the quality changes.
When the thickness of the workpiece material has a large deviation and cannot meet the quality of life management requirements, the grinding wheel angle should be checked. The thickness deviation in the width direction of the workpiece of the automatic double-end grinding machine should be different from the opening design of the upper and lower points in the vertical direction of the grinding wheel. If there is a certain thickness deviation in the development of a length research direction, it should be mainly because the angle of the grinding wheel is too large or too small, or through reverse adjustment. Therefore, if there is no thickness deviation, adjust the angle. The roundness of the part is not ideal, and the middle height level of the part is not high; observationFull-automatic double-end grinding machineWhether the grinding sound, cutting sound and fire heart are abnormal.
