Technical Research and Development
Assembling the whole machine off the line: Finished product factory inspection test --- surface treatment (painting) --- nameplate playing --- packaging --- warehousing
Type test (new products, products with special requirements, old products regularly)
Typical process of gear processing for major parts:
Blank forging --- rough turning (generally leave a margin of 2mm) --- normalizing (tempering) --- semi-finishing turning (leave the amount of grinding) --- hobbing (leave the amount of grinding) --- gear insertion (or milling the keyway) --- carburizing, quenching, tempering --- sandblasting --- grinding bore and OD --- gear grinding --- inspection --- cleaning and oiling --- packaging into the warehouse.
Note: Strict first inspection for each process, 100% inspection for key processes (grinding teeth, grinding outer diameter, inner hole), 40% sampling inspection for precision turning,, sample testing for each batch of heat treatment, and 25% sampling inspection for the rest of the processes.
