Double Sides Grinding Machine

Double sides grinding machines play a vital role in the field of precision machining, and the design and selection of the spindle material is of utmost importance. The spindle of this grinder is made of high-quality 40Cr material, which is favored for its excellent strength and wear resistance. During the manufacturing process, the spindle first undergoes a forging process, which enhances the mechanical properties of the material by making its internal structure more compact through the combined effects of heat and pressure.

Subsequently, the spindle will receive annealing treatment, through which the internal stresses generated during the forging process can be eliminated, further enhancing its toughness and plasticity. The subsequent normalizing treatment further optimizes the material's organizational structure and properties, laying a solid foundation for subsequent processing.

After completing the normalizing treatment, the spindle enters the critical tempering stage. Through the exquisite combination of quenching and tempering, the comprehensive mechanical properties of the material reach the peak state. The application of high-frequency quenching technology has brought about a significant improvement in the surface hardness and wear resistance of the spindle, ensuring its stability and durability under high-speed rotation and friction environments.

Finally, the application of stability treatment enables the spindle to maintain stable dimensions and performance over a long period of time, thus greatly extending the service life of the grinder.

In addition to the spindle, the guideway of the disc type double sides grinding machine should not be overlooked. It is made of high-quality Gr15 material, which is known for its excellent wear resistance and fatigue resistance, ensuring that the guideway can still maintain high precision and smooth operation under heavy loads and frequent friction. Meanwhile, the inlet and outlet plates are made of 65Mn material with high strength and good toughness, which can withstand all kinds of shocks and vibrations in the process of inlet and outlet.

In terms of the feeding system, the application of high-precision ball screws brings higher smoothness and accuracy to the feeding movement, which effectively improves the quality and efficiency of grinding. Especially worth mentioning is the unique design of the spindle of the double sides grinding machine. It only carries out rotary motion without spline and telescopic motion. This design not only simplifies the mechanical structure and reduces internal consumption, but also further extends the service life of the grinder and realizes the goal of energy saving and consumption reduction. The high efficiency, stability and durability of this design make this double face grinder increasingly prominent in industrial production.
