With the rapid development of automobile industry, bearing industry and it electronic industry, double face grinder has developed rapidly because of its high efficiency, high precision and high degree of automation. Especially with the rise of smart phone industry, the double grinding machine is used to grind the glass pieces of mobile phone, which expands the application scope of the double grinding machine and brings a huge business opportunity. At the same time, it also puts forward higher requirements for the machining accuracy, efficiency and stability of the machine tool. The market needs a high-efficiency and high-precision double face grinder which can complete the rough grinding, semi-fine grinding, fine grinding and smooth grinding of workpieces at one time, so that the grinding process which can be completed by common three machine tools can be completed by one machine tool, so as to save labor cost and improve processing efficiency.

Horizontal double face grinder has a very broad application prospect in modern manufacturing industry. Its main advantages are as follows:

1. At the same time, grinding the two ends of the workpiece, the surface parallelism, perpendicularity, surface roughness and dimensional tolerance of the workpiece can meet the requirements of precision accuracy.

2. In the process of double face grinding, due to the same magnitude and opposite direction of the grinding force generated by the upper and lower grinding wheels, the grinding force on the workpiece is close to zero. Therefore, the workpiece feeding does not need a large driving force, only a small force can drive the workpiece to carry out grinding, so that the internal stress of the workpiece is small, ensuring that the workpiece is not easy to deform after processing. In grinding non-magnetic materials or non-metallic materials, double face grinder shows unique advantages.

3. The double face grinder can grind the workpiece continuously, and can grind thousands of workpieces per hour, which is very suitable for mass production, thus reducing the cost of workpiece processing and manufacturing. The machine is also equipped with automatic loading and unloading mechanism, which can operate continuously, reduce the labor intensity of workers and improve grinding efficiency. In order to reduce the auxiliary time of grinding, online measurement and automatic compensation device are added to the double face grinder, which can reduce manual operation and automatically identify qualified workpiece, and ensure the stability of workpiece quality.

4. The range of workpieces that can be processed by double face grinder is very wide. Most of the metal and non-metal workpieces that need to grind two parallel planes can be processed by double face grinder. The common ones are piston ring, washer, connecting rod, valve piece, silicon piece, ceramics, etc. In addition, with the improvement of the double face grinding technology, some workpieces that are difficult to be processed, such as workpieces with large difference in the area of the lower end surface, can now be grinded with the double face grinder through the control of the rotation speed of the two grinding wheels and the development of the special grinding wheel. Double face grinder can process the smallest workpiece including bearing needle, clock and watch parts, mobile phone glass, etc., and the larger workpiece can be processed has the frame of large machinery.
