Those familiar with the mechanical industry know that centerless grinding machine is a kind of grinding machine that does not need to use the axis positioning of the workpiece. It is mainly composed of grinding wheel, adjusting wheel and workpiece support. The grinding wheel actually does the grinding work, and the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece. These three parts can be a number of ways to cooperate, but stop grinding except, the principle is the same. So what are the common problems of centerless grinder grinding? How do we solve it?
First, the causes of the parts are not round:
1) The guide wheel is not rounded. The guide wheel should be repaired until the guide wheel is rounded.
2) The original workpiece ellipse is too large, the amount of cutting is small, and the grinding times are not enough. The grinding frequency should be increased appropriately.
3) The grinding wheel is dull. Repair the grinding wheel.
4) The grinding amount is too large or the cutting amount is too large. Reduce grinding and cutting speed.
Two, parts polygon causes are:
1) The axial thrust of the parts is too large, so that the parts press the baffle pin tightly, resulting in uneven rotation. Reduce the inclination Angle of grinder guide wheel to 0.5° or 0.25°.
2) The grinding wheel is unbalanced. Balanced grinding wheel
3) The parts center is too high. Properly reduce the center height of the parts.
Three, the reasons for vibration marks on the surface of parts are:
1) Unbalance of grinding wheel causes vibration of machine tool. The grinding wheel should be balanced.
2) parts center forward to make the workpiece beat. Work center should be lowered appropriately.
3) The grinding wheel is dull or the grinding wheel surface is too polished. Only the grinding wheel or appropriate increase in grinding wheel dressing speed.
4) If the rotation speed of the adjusting wheel is too fast, the selection speed of the adjusting wheel should be appropriately reduced.
