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 checkered piston:
Material: 20cr2*114
thermal treatment use overall carburizing →quenching heat treatment
→ Processing using high precisioin checkered 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: 20cr2*114
Our company can according to the customer request to make special
specifiCATEEEEEEion 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.
