【Oil pump dummy cover assembly】
CVT parts for medium-sized vehicles.
Cold-forged shaft is pressed into the cast cover and numerous deep-hole oil hydraulic circuits.
This product become a pioneer in long drill processing.
Deep hole processing at ultra-high speeds is impressive.
We designed our own inspection devices to detect the presence of foreign substances (contamination) in hydraulic circuits dug deeply using long drills.
Other foundations of our line production may be found everywhere, including high-pressure washing for deburring, clean rooms to avoid contamination, pressure and completed dimension inspection equipment, and so on.
