China has a large market demand for high-precision precision parts and high-precision grinding machines, and there is a big gap between China and foreign countries, like Europe, America and Japan.There are few domestic manufacturers of high-precision vertical double-disc grinders precision equipment. Today, I would like to show you the advantages of CNC high-precision vertical double-disc grinding machine(DDG)

Compared with ordinary surface grinders, the high-precision vertical DDG  is a kind of surface grinding equipment with high processing accuracy and faster processing cycle. The surface grinders you have seen before are usually horizontal, while ,The high-precision vertical double-disc grinder its upper and lower grinding wheel shafts are perpendicular to the ground.

DDG is different from ordinary surface grinders in that it does not rely on magnetism to fix the workpiece, but the upper and lower surfaces of the workpiece are simultaneously ground. That is to say, no matter the material of the workpiece is metal, or other non-magnetic materials can be processed. In addition ,DDG can simultaneously process two parallel surfaces with high precision and nice roughness in one grinding stroke. Compared with surface grinders, not only the processing efficiency is greatly improved, but also the form and position tolerances and dimensional tolerances can be well improved. 

The vertical DDG also has the characteristics of uniform feed, fast rotation speed and high efficiency. Compared with CNC lapping machine, the processing efficiency is 10 times that of the CNC lapping machine on the basis of achieving the same accuracy, and it is much better than the lapping machine in terms of dimensional tolerance.

The main types of high-precision vertical DDG are divided into oscillation type and ’C’through type. At present, it is divided into 305mm, 455mm, 585mm, 760mm, etc. according to the diameter of its grinding wheels.

The oscillation type DDG of Japan, South Korea, and Europe are widely used in various industries. The processing accuracy of this method is very high, generally within 0.002mm. There are very few domestic manufacturers that can replace imported oscillation type DDG, and Yuhuan CNC machine tools co.,ltd are one of them. Although the processing efficiency of oscillation DDG is slower than that of the ‘C ‘through-type one , the processing accuracy is very easy to guarantee. Yuhuan  DDG is mainly used in double-disc grinding of core precision components in air-conditioning compressors, automobiles , powder metallurgy, aviation, electronics, and robotics etc. industries

C’through type DDG is suitable for processing some parts that require high efficiency and not so strict on accuracy. Generally , it’s suitable for mass production of workpieces such as automotive gaskets, blades, and bearing rings.
