Grinding wheel

Superior performance of the grinding wheel must have sharp grinding at the same time, good self-sharpening and high durability features. Manufacturing and grinding wheel

Main consideration when combined with agent, concentration of abrasive, grinding wheel and abrasive hardness.

1

Combining with the agent

CBN

Four of abrasive binder (resin, ceramic, metal, electroplating), ceramic bond

CBN

Abrasive tool development

The fastest. Worldwide, the ceramics

CBN

The proportion of abrasive tool has been developed from

20

century

80

s

4%

Up to now

50%

Above, increase

Speed rapidly. Because of the ceramic

CBN

Abrasive grinding with high efficiency, good shape retention, high durability, easy to repair and abrasive

Powerusageeffectiveness high (as

75%

Above, the rest of the type of binder for

5060%

Grinding wheel long life and other advantages, thus become a high efficiency, high precision

The degree of grinding the grinding tool of choice. At present, used in grinding of camshaft

CBN

Grinding wheel are all made of ceramic bond.

2

Abrasive selection

Main body of grinding, abrasive abrasive, its performance is good or bad directly affect the grinding effect.

CBN

Abrasive corundum grinding

Compared to material has higher hardness and strength, thus cutting sharp and wear-resisting. Grinding processing such high strength of the camshaft

Next, the use of

CBN

Grinding is the best choice. Different type of

CBN

Abrasive, due to the difference of manufacturing process, and its crystal morphology, star

Particle shape also each are not identical, each with different strength, thermal stability, resistance to chemical erosion and breakage feature. Should be based on"

Mixture of species, grinding workpiece and grinding way is different, choose different type of abrasive. Need to point out

CBN

Abrasive in the high

Under the temperature easily react with water and alkaline oxide and make its structure is damaged, which is to choose the types of grinding fluid, pressure

And traffic factors must be considered.

3

The concentration of

Grinding wheel concentration said when grinding wheel face of the grinding grain number per unit area to grinding, high concentration

Can bring higher grinding ratio,

200%

The concentration ratio

100%

Concentration of grinding wheel life is long

45

Times. At present, high speed, high efficiency grinding were adopted

High concentrations of grinding wheel, such as import ceramic grinding camshaft grinding machine matching

CBN

Grinding wheel concentrations are generally

200%

4

hardness

Abrasive hardness grade said the size of the binder on the abrasive holding force, manufacturers one of the important indices for process control, is also used

The main families choose abrasive performance parameter. Wheel hardness uniformity and stability and hardness of rational choice is to ensure the quality of grinding

Important premise.

Foreign ceramic
