Uses: Used for connection and communication of electric vehicle lubrication, cooling and other pipeline systems, also known as pipe joints, a special high-precision pipeline connector, similar to common hydraulic and gas pipeline fittings; Features: It is a special high-precision connection pipe fitting, similar to common hydraulic and gas pipeline fittings; Generally, there are special pipeline interfaces at both ends, and the middle six or eight edges are used for fixing and locking, which requires high appearance and strength. Process requirements: blank is generally made of stainless steel casting, the main process includes: turning process; the main processing equipment has CNC lathe equipment. Key inspection items: appearance, thread, size and other items; special stop gauge is adopted for thread inspection, with fewer inspection items and inspection instruments.

Uses: Used for motor products for electric vehicles, motor spindles, and key components of motors; Features: It belongs to a high-precision, high-strength shaft part, with keyways on the shaft and multiple step circles at both ends (used to install bearings, Transmission parts, oil seals and other parts), one end has splines, multiple outer surfaces need to be ground, and the coaxiality between outer circles is very high, roundness, cylindricity, size, roughness, dynamic balance and other items are very high requirements. Process requirements: the blank is generally made of steel bars or forgings. The main processes include: rough machining-heat treatment (carburizing and quenching of low alloy low carbon steel)-semi-finishing-grinding and other processes; The main processing equipment includes CNC lathes, precision CNC cylindrical grinding machines, quenching equipment, processing centers, gear hobbing machines and other equipment. Key testing items: surface roughness, roundness, cylindricity, coaxiality, spline, outer circle diameter, keyway, hardness, metallographic and other items; Key testing equipment: large and medium-sized precision coordinate measuring machine, roundness meter, gear detector, dynamic balance testing machine, hardness meter, metallographic microscope and other high-precision testing equipment.
