Automobile motor shaft

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.
