Our Advantages

1. Using 20CrMo steel as raw materials, which are provided by domestic famous manufacturer;
Forging again and again to make forming, to make internal organization more tight, and increase products' wear-resistance.

2. Using advanced CNC machine in strict accordance with products' technical requirement to manufacture and ensure each position's
size which convenient to equip.

3. Having international advanced heat treatment technology, using carburization treatment on them, guarantees their surface's
thickness of carburized Layer and hardness; Meanwhile good core toughness and ensures that the product dose not crack under high intensity work.

   The material is 20CRMO, but the metal hardness is around 52 degrees, which is too hard and easy to be brittle. Moreover, when the drill rod is loaded, it is easy to wear the drill rod surface if machine force is used. On the contrary, if the bushing is too soft, it will wear away too much.
   Bit rod guide sleeve failed;

   Guide sleeve or poor lubrication for guide sleeve abrasion resistance is poor, accelerate the wear of guide sleeve, drill rod and the clearance between the guide sleeve sometimes reach more than 10 mm, the centerline deflection extremely easily, then drill rod when the piston movement to the end of the drill rod, piston by reaction is an eccentric force, the formation of a component of the force acting on the radial force on the piston, the piston under the action of radial force deflection a side, make the original gap, the oil film is damaged, the formation of dry friction, make the surface of the piston and cylinder body injury quickly. Its characteristics are that the tensile area is large, about 1/3 of the cylinder area, and the tensile trace is short, equal to the displacement of the bit rod.
The raw materials of crushing hammer fittings are all made of high quality alloy steel through special forging process, so that the products reach the requirements of high strength and high quality.
