Produce description
Large long shafts and rollers are core components in heavy machinery. They usually operate in high-speed, high-load working environments and need to withstand tremendous pressure and torque. These shafts are usually made of high-strength, high-wear-resistant materials, such as alloy steel, stainless steel, etc. In order to meet different working environments and usage needs, they vary in size, shape and surface treatment.
The process of machining large long shafts and rollers is complex. First, suitable raw materials need to be selected and heat treated to improve their mechanical properties and wear resistance. Then, rough machining is performed with a CNC machine tool or lathe to remove excess material and form the basic shaft shape. Next, finishing processing is performed, including milling, grinding, etc., to ensure the dimensional accuracy and surface quality of the shaft. Finally, heat treatment and surface treatment are performed to improve the wear resistance and corrosion resistance of the shaft.
Large long shafts and rollers have the following advantages:
- High strength: Able to withstand high load and pressure to ensure stable operation of the equipment.
- High wear resistance: The surface is specially treated to have excellent wear resistance and extend the service life.
- High precision: Use advanced processing equipment and technology to ensure the dimensional accuracy and surface quality of the shaft.
- High stability: When operating at high speed, it has good dynamic balance and stability, reducing the vibration and noise of the equipment.
