PRODUCTION PROCESS
Through/Side/ 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: 20crmo
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 .
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.
