Krupp HM170 small back head of hydraulic hammer

The process and character:

1. The back heads, made from 42CrMo steel, are forged according to large proportion, to fully ensure products’ density and performance, thus improving tightness.
2. Using advanced CNC machine, in strict accordance with products’ technical requirement to forge products, to ensure each position’s size, convenient to equip.
3. Having international advanced heat treatment technology, ensure heat and soaking time, which makes the whole get certain hardness ;products are out of shape at very little rate, thus reduce the possibility of air leakage.
4. Using advanced grinding equipment to make them completely match the contact surface of the cylinders, thereby getting the function of store N2.

Function: store N2, and drive piston work normally

Character: No air leakage, well wear-resistance

Our advantage:

have own forging equipment

short production cycle

Products from raw materials to finished products in one step

obvious competitive price.

The process of production:

  tempering→milling flat→punching→lathing →coutour processing→heat treatment→polishing
