Integrated production from lathe machining, heat treatment, inner diameter grinding, outer diameter grinding, to assembly of intake valves for marine diesel engine fuel pumps.
We would like to introduce a machining case for the "intake valve for marine diesel engine fuel pumps." Starting with lathe processing that leaves the minimum grinding allowance, we performed high-precision inner and outer diameter grinding, followed by hand polishing and seat fitting by skilled craftsmen, as well as assembly adjustments. We have reduced time loss due to logistics and valve rod distortion prevention and correction through heat treatment at our own factory. 【Processing Steps】 ■ Valve Rod - Lathe / Heat Treatment (Vacuum Quenching) / Outer Diameter Grinding ■ Casing Body - Lathe / Machining Center / Heat Treatment (Carburizing Quenching) / Inner Diameter Grinding / Outer Diameter Grinding - Inner Diameter Honing / End Face Lap Finishing ■ Conical Ring - Lathe / Heat Treatment (Carburizing Quenching) / Wire Cutting (2-part) ■ Assembly - Casing Body and Valve Rod Seat Fitting / Assembly *For more details, please refer to the PDF document or feel free to contact us.
