The working principle of the double disc grinder gives it a unique processing advantage - the upper and lower grinding discs rotate in parallel and relative, and the planetary carrier drives the workpiece to make compound movements, so that every part of the workpiece surface can be evenly contacted with the grinding medium. This "double disc clamping + planetary trajectory" design can reduce the processing time by more than 30% compared with the single disc equipment, and at the same time make the surface accuracy achieve a near mirror effect. The grinding fluid plays a dual role in it: it not only reduces friction loss like lubricating oil, but also takes away grinding debris in time to ensure that the processing environment is clean. This mechanism of "cleaning while grinding" avoids the surface scratches that are common in traditional single disc equipment in principle.

In the processing of automotive parts, the advantages of the double disc grinder are particularly direct. Taking steering pump gears as an example, the traditional process requires multiple turning over and grinding, while the double-disc equipment can complete double-sided finishing with one clamping by synchronizing the upper and lower discs. The noise during gear engagement is significantly reduced, and the driving experience is improved. In the production of hydraulic valve blocks, the equipment can accurately control the grinding pressure, so that the dense cover can achieve the accuracy of "no leakage". After a certain company adopted it, the leakage failure rate of the hydraulic system decreased by more than 90%. This is a true portrayal of the advantages of the double-disc grinder "one-time processing up to standard".

For fragile materials such as electronic ceramics, the flexible processing characteristics of the double-disc grinder are even more crucial. It can achieve accurate grinding on the alumina ceramic substrate by adjusting the pressure and grinding track, which not only ensures dimensional accuracy, but also avoids edge cracking. After the introduction of an MLCC manufacturer, the yield of ceramic substrates increased by nearly 20%, thanks to the unique advantages of the equipment that can be ground quickly and treat precision components like precision components. In addition, the equipment's grinding liquid circulation system and energy-saving drive design can also save the enterprise consumables and electricity costs.
