Double disc grinding machines: Innovations for efficient and stable machining technology

A particularly critical function in the design of a double disc grinding machine is the rapid forward and reverse movement of the grinding head. The realization of this function depends on the precise and continuous operation of the hydraulic system. The strong power of the hydraulic system enables the grinding head to respond quickly and accurately to operating commands and to reach the intended position quickly, thus ensuring the continuity and efficiency of the grinding process.

The use of the hydraulic system not only provides the power for the rapid movement of the grinding head, but also, through its continuous operation, successfully eliminates the tiny gap between the ball screws. This small gap, although seemingly insignificant, may have a non-negligible impact on the grinding accuracy and stability. The continuous operation of the hydraulic system ensures that the ballscrews are always in optimum working condition, thus eliminating this potential effect.

The advantage of this design is that it significantly improves the working stability of the grinding machine. Whether in high-speed grinding or low-speed fine machining, the grinding machine is able to maintain excellent stability, ensuring a high degree of accuracy and consistency in the products produced. At the same time, this also ensures the safety of the grinding process, so that the operator does not have to worry too much about the stability of the equipment during operation.

We have made great efforts in manufacturing the spindle, which is the core component of the double disc grinding machine. We use high-quality 40Cr material, which is known for its excellent strength and toughness. In order to ensure the spindle's optimum performance, it is carefully forged, annealed, normalized, tempered, hardened at high frequency and stabilized. This complex series of process steps ensures that the spindle has excellent strength, toughness and wear resistance, and is able to maintain stable performance over long periods of operation.

This spindle design not only ensures the stability of the grinder over long periods of operation, but also greatly extends its service life. It is able to withstand large cutting forces and impacts, and maintains excellent performance even in harsh working environments.

In addition, it is worth mentioning that the double face grinder has made a bold innovation in the grinding head moving method. While conventional grinders usually use spindle telescopic grinding, our double face grinder utilizes an innovative V-shaped steel-inlaid needle bearing guideway design. Instead of a telescopic movement of the spindle, grinding is accomplished by means of an integral movement.

This innovative design offers a number of advantages. First, it maximizes the rigidity of the grinding machine. Thanks to the integral movement, the grinder is better able to resist the interference of external forces during the grinding process, thus maintaining higher machining accuracy. Secondly, this design allows the grinder to withstand greater cutting forces during the grinding process. This means that we can use a larger tool draft for machining, thus increasing work efficiency. At the same time, higher machining accuracy also ensures the stable improvement of product quality.

In summary, the double disc grinding machine has been carefully designed and optimized in terms of the rapid movement of the grinding head, the manufacturing of the spindle and the way the grinding head moves. These innovative designs not only improve the working efficiency and machining accuracy of the grinder, but also ensure the stability and reliability of the product. This makes the machine a reliable and efficient processing machine.
