Description
Technical Field
The invention belongs to the technical field of screw processing, and particularly relates to a screw production process.
Background
The screw is a main part and a key part in a mechanical part, and the working environment of the screw is usually high-speed, high-pressure and high-temperature rotation, so that the screw is required to have good tensile strength, bending resistance and fatigue resistance, high hardness and wear resistance and good toughness, is widely distributed in various industries such as automobiles, metallurgy, machinery, petroleum, electric power, building materials, ships and the like, and is required to have good damping vibration attenuation and noise reduction functions in some industries. In the industry, the processing of long screws has been a relatively troublesome problem in turning. The reason is that the slender screw has poor rigidity and is easy to deform in processing, so that the error of the processed screw is large, and the processing quality of parts is not easy to ensure. And the long screw rod is improperly clamped during turning, so that the long screw rod is easy to bend and deform under the action of cutting force and gravity to generate vibration, and the machining precision and the surface roughness are influenced.
