The glass is wind-proof, light-permeable, stable in performance, various types have different characteristics due to the use of different occasions, the scope of application is very wide. When we are choosing glass, besides paying attention to price, still answer its kind and performance to have certain understanding, make full use of strong points to avoid weak points, just can find the material that suits to use more.

Conventional cylindrical grinding uses the center holes at both ends of the workpiece to support the workpiece between the head of the grinder and the center of the tailstock. During grinding, the workpiece rotates driven by the spindle while the grinding wheel feeds horizontally.

Advantages of brazing process: Ni-Cr alloy itself has high strength, and higher bonding strength can be obtained after brazing than silver base alloy, Ni-cr alloy has high melting point and good grinding resistance. However, it still has certain limitations. Due to the high brazing temperature (1080℃), it is easy to cause thermal damage to the diamond and reduce the strength of the diamond. Brazing under vacuum or argon protection ensures that the bonding strength between the alloy layer and the diamond and the steel matrix can be higher and the thermal damage oxidation of diamond can be minimized.

One of the objectives of metallurgists as they are developing better HSS (high-speed steels) is to get a more uniform distribution of fine microcrystalline carbides throughout the HSS. This makes the steel far more wear resistant, so the time between tool sharpening is greatly extended. But it is not without its attendant difficulties, namely the sharpening of the carbide grains distributed throughout the HSS

The causes of grinding cracks may be as follows: the surface stress of the workpiece exceeds the fracture limit, that is, the workpiece has residual mechanical stress and thermal stress in the surface part due to previous grinding or heat treatment. Because this part of the grinding just to maintain the balance of the stress, resulting in its residual stress over the strength of the workpiece, from some will produce a grinding crack.
