grinding wheel before surface grinder processing

Grinding wheel before surface grinder machining of preparation

If the grinding wheel is not prepared well, it will become the root of many grinding problems in the future. The preparation of grinding wheel for surface grinder includes installation, balancing, finishing and dressing.

First of all, the grinding wheel should be installed according to the instructions of the machine tool plant to ensure that it is in a good original balance state and minimum runout before dressing.

Second, the installation should be carefully operated to avoid damaging the inner hole. When the inner hole is rotating at high speed, it is often caused by improper handling and installation.

Third, when installing the vitrified bond grinding wheel, must use the paper washer.

Fourth, tighten the flange of surface grinder with smooth torque and tightness.

After installation, rough balancing, trimming and fine balancing should be done in turn, and then grinding can be started. If the original state is very unbalanced and has a large jump, additional trimming and rebalancing are often needed. A good balance will keep the grinding surface smooth and prolong the service life. At the same time, the correct dressing will make the grinding wheel maintain stable grinding surface and grinding effect.

The sharpness and shape accuracy of grinding wheel of surface grinder depend on dressing method. Therefore, the dressing device should be in good working condition at any time, which is the same for single point diamond dresser or diamond roller driven by motor. Single point diamond correction is a common method for dressing ceramic bond, which often leads to unstable performance. Therefore, the method and procedure of dressing should be adjusted accordingly.

When grinding workpiece, the typical method is as follows:

Surface grinder grinding wheel rough grinding a certain amount of processing allowance, and then change the dressing parameters, and then finish grinding the workpiece. The common method is that when the grinding wheel is rough repaired, the diamond makes a rapid cross feed along the outer circle of the grinding wheel, while in the fine dressing, the transverse feed speed of the corrector is greatly reduced to obtain a smooth surface of the grinding wheel and the workpiece.
