(1) to pay attention to the contact of the wheel and the important parts

Hissing sound came when grinding wheel for grinding the workpiece surface, the wheel will take away the workpiece surface water stains, while flashed a faint spark, then only increase the coolant, the coolant liquid than ordinary saponification the depth slightly higher, but requires that the filter clean, and then feed. Note that each feed rate for each double stroke 0.005mm until sparks disappear, grinding disc. The transverse feed handwheel to feed direction Banxia, ??the wheel slightly closer to the workpiece, but do not feed, so once polished workpiece, the ultimate guarantee of the workpiece surface roughness up Ra0.02μm.

(2) to prevent the workpiece expansion

In the the summer grinding, the machine lights close to the workpiece to prevent the bulbs heat resulting workpiece expansion affect the quality of grinding.

(3) work even surface nap

It is the coolant clean or grinding wheel surface floating sand, strict nearly filtered coolant or floating sand washed off.

(4) a partial burns
This is due to inadequate cooling liquid feed excessive or grinding wheel caused by blunt.

(5) local tiny corrugated surface of the workpiece.

The end of machining, the workpiece partially occur fine corrugated. The possible causes of the corrugated loose spindle motor vibration or other factors, which according to the actual situation, select the appropriate measures to deal with.

        We hear the word of the grinding wheel, the first understanding is to know that it is an abrasive, grinding wheel Grinding Wheel production of various types of range. Now introduces One CBN wheel. CBN grinding wheel, also known as cubic boron nitride grinding wheels, CBN grinding wheel is yet another addition to diamond superhard materials, mainly used to make the wheel, as well as knives and other CBN grinding wheel particles sharp suitable for grinding all kinds of hard materials such as diamond composite tablets.
        CBN grinding wheel produced by cutting wheel, according to the different processes and different components of the binding agent can be divided into the following four. Their nature and purpose (referring to the machining purposes) is also different.
        Wheel production process is simple, low cost of production. Molding simple but only one layer of coating, can not be corrected, in the process, it is difficult to know when the grinding layer is damaged. Suitable for small batch machining and geometry complex molding grinding with and as a correction wheel with.
