3. Flow for screw production

Cutting stell—Machining—Drill hole—Quenching&Tempering—Machining outside diameter—Milling screw arris—Heat treament—Milling screw arris accurately —polishing —grinding outside diameter—milling spline—Bimetallic/Nitriding— polishing again—Inspecting&Packing

4. Flow for barrel production

Cutting stell—Machining—Drilling hole—Rough machining—Hardening&Tempering
—Machining again—Grinding inner hole—finish machining—milling feeding hole—
Bimetallic/Nitriding—grinding inner hole again—polishing—package

5. Equipment

Finish machining equipments for screws and cylinders, CNC equipments, heat-treatment equipment, Bimetallic and nitriding furnaces, constant-temperature quenching furnaces, welding bimetallic powder, Welding machine and inspection equipments etc.
