The Idling gear fabricating machinery is CNC Lathe and tooth width of 24.3, The hardness of the product is required to be ≤230HB, there are many hardness classification, among them, brinell hardness is determined by the depth of indentation plastic deformation hardness index.

The indenter of rockwell hardness tester C scale is a diamond cone with an apex Angle of 120 degrees. The test load is a definite value, and the Chinese standard is 150 kg force.

The indenter of Brinell hardness tester is hardened steel ball (HBS) or hard alloy ball (HBW). The test load varies with ball diameter from 3000 to 31.25 kg force.

Rockwell hardness indentation is very small, the measurement value is local, the decimal point must be measured to average, applicable to finished products and thin sections, belonging to a class of nondestructive testing.
