Magnesia grinding wheel

Calcined at 800 ~ 850℃, calcined with natural magnesite as raw material, magnesia is a kind of fine powdery gas rigid cementation material. The color is pure white, or gray, or near pale yellow, fresh material has a shimmering glassy sheen. Specific gravity 3.2, bulk density 800 ~ 900 kg/m3, magnesia content not less than 75%, coagulation time: initial coagulation no earlier than 40 minutes, final coagulation no later than 7 hours.

Four methods of grinding wheel dressing

The process of shaping or trimming the blunt surface of the grinding wheel with a dressing tool to restore the grinding performance and correct geometry of the working surface. Timely and correct dressing of grinding wheel is an indispensable link to improve grinding efficiency and ensure grinding quality. Grinding wheel dressing generally includes turning, diamond roller, grinding and rolling, etc.

Analysis of blockage factors of grinding wheel

The influence of grinding wheel linear velocity is more complex, because of the increase in wheel linear velocity grinding grain of the maximum cutting depth is reduced, chip cross-sectional area is reduced, cutting and grinding heat increases at the same time, the two factors can make jam quantity increases, but when the grinding wheel linear velocity up to a certain extent, such as more than 50 m/s) grinding wheel blocking quantity drops greatly.

Control method of glass grinding edge chipping

The most common problem encountered when grinding glass is that the amount of edge chipping exceeds the range ,so why does edge chipping occur? The reason is that glass has an amorphous and irregular non-crystalline structure, which means that edge chipping is inevitable and random when grinding glass. The input determines the output effect in the grinding system. The four major input factors are equipment, tools, parameters, and workpieces. The edge chipping is the result of the combined effect of these factors.

Honing is a three-in-one metalworking process

Honing is the ultra-precise machining process trusted by job shops and high-production manufacturers to create parts that perform at the highest levels of speed and efficiency. No boring or grinding process is capable of delivering such fine levels of roundness, straightness and surface detail. When integrated into your manufacturing process, honing is the difference between a part that works and a part that performs.

Diamond and CBN Abrasive Grain Size Control

Mesh refers to the number of holes on the screen per square inch, 50 mesh means 50 holes per square inch, 500 mesh is 500, the higher the mesh, the more the holes, and the smaller the abrasive particle size. The finer the granularity. The filter screen divides the abrasive grains into different sizes.
