Hydraulic Breaker Parts Production Process:
Through/Side/Hex Bolt:
Material: 42crmo Bolt has 10.9 Grade and 12.9 Grade Heating processing →Quench→Temper→Surface treatment: natural colour and black coating
Mounting Pin:
Material: 42crmo Hardening→Tempering-finish machining→ Mid frequency induction hardening →Outside diameter grinding The depth of quenching is 3MM and the high surface hardness,with high Durability.
Special checked piston:
Material: 20cr2*114 thermal treatment use overall carburizing →quenching heat treatment → Processing using high precision checked grinding technology With high surface precision and good fineness . Hydraulic oil can adhere to the piston surface well and forming oil film , with good lubricity and abrasive resistance , to extend the piston’s life , and keep the force of impact .
Custom Piston:
Material: 20crmo ,2*114 Our company can according to the customer request to make special specifiCATEEion piston: According to the assembly need grinding piston diameter, Control piston in tolerance range, make piston and cylinder
body between the fit clearance to achieve the best effect.
Inner Bush:
Material: 42crmo or 20crmo Forging blank → finish machining → carburizing→ quenching→Fine grinding Product accuracy is high and stand wear and tear.
Front cover:
Material: 42crmo or 20crmo Forging blank→finishing (finish machining) → Carburizing heat treatment →assembly surface fine grinding Product is wear-resisting and impact resistance.
Front Head,Cylinder,Back Head:
Material :20crmo or 35crmo, Forging blank→CNC(finish turning)→Precision turning (side A&B)→Polishing to remove burrs→Semi-finished product inspection→ Heat treatment →Carburizing and quenching → Precision machining of short holes and frond faces (Accurate grinding) → Grinding long holes (Accurate grinding) → Finished product inspection
