In recent years, due to the tremendous development of national defense, aviation, high-speed railway, automobile, mold, machining and other industries, the domestic CNC internal grinder can not meet the needs of domestic machining enterprises, leading to the domestic enterprises importing foreign CNC Internal Grinder. The high-speed, compound, fine and high-end CNC internal grinder is the development direction of domestic surface grinder.

CNC cylindrical grinder is the mainstream product of grinder industry. Moreover, it is very common in mold factories and hardware processing plants, and has become a common equipment for technicians in the machinery industry. However, in the operation of cylindrical grinding machines, the selection of abrasives is very important. Then let's talk about how to select the abrasive corresponding to the CNC cylindrical grinder?

1. Selection of abrasives for cylindrical grinder

Corundum grinding wheel is used for hardened or non hardened steel rolls; Silicon carbide grinding wheel is used for cold cast iron roll, rubber roll, copper roll and granite roll. Corundum grinding wheels should be selected for different steel rolls to obtain high grinding accuracy and surface quality. For example, chrome corundum (PA) grinding wheel is used for alloy steel roll, zirconium corundum (ZA) grinding wheel is used for heat-resistant alloy steel roll, and single crystal corundum (SA) is used for stainless steel roll.

2. Selection of grinding wheel size of cylindrical grinder

Coarse grain size (24 ~ 60) grinding wheel shall be selected for rough grinding; Fine grain (60 ~ 100) grinding wheel shall be selected for fine grinding; 150 grit grinding wheel is used for precision grinding; In ultra precision grinding or mirror grinding, micro powder (W63 ~ W14) grinding wheel is generally used.

3. Selection of grinding wheel hardness of cylindrical grinder

The harder the grinding roller surface, the softer the hardness of the grinding wheel should be.

In our socialized production and construction, there are many mechanical equipment. These mechanical equipment can greatly reduce the labor intensity of everyone, save resources, and improve the production efficiency in everyone's production, so as to create greater benefits for the production and socialized construction of the factory. Therefore, the positioning standard of NC cylindrical Hangzhou grinder determines the subsequent processing so as to ensure the quality and efficiency.
