In the shaft workpiece grinding method is commonly used cylindrical grinding, mainly through the application of grinder equipment. There are four main methods for cylindrical grinding.
Method one: longitudinal grinding method. Mainly through the high-speed rotation of the wheel, the workpiece rotation, and then through the wheel in the vertical direction of movement, in order to achieve the workpiece grinding effect. However, the efficiency is relatively low, the surface quality of the workpiece after grinding is better, and the surface roughness of the workpiece is lower.
Method two: cross-grinding method. Generally similar to the longitudinal grinding method, in this case, the grinding force is applied to the workpiece mainly through the grinding wheel instead of the worktable up and down. For this method of sharpening, the efficiency is more engaged, but due to sharpening when the sharpening force increases, will produce a certain amount of heat, so that the grinding temperature, the temperature is too high Adequate coolant should be provided for cooling.
Method three: composite grinding method. Mainly the horizontal grinding and vertical grinding two effective combination of methods, first through the horizontal grinding method, and then through the longitudinal grinding method for processing. Through the combination of the two methods, both efficient grinding and high quality grinding are guaranteed.
Method four: deep grinding method. This method of grinding is relatively efficient, but one problem is that the grinding wheel dressing process is more complicated, and at the same time, the specific structure of the workpiece needs to be considered. Moreover, the cutting length and the cutting length of the grinding wheel are both A clear requirement, must reach a length Caixing.
For the above four commonly used methods, each method has its own advantages and disadvantages, so in the actual processing, should be based on specific requirements to choose from.
