Grinding wheel for deep depth cutting

Slow-feeding Large-depth deep-grinding, also known as deep-grinding or swaying grinding, is to grind the workpiece with a large depth of cut (up to 30M or more) and a very low table, one or several times. It can be used to grind high-hardness and high-toughness materials such as heat-resistant alloys, 7″ cut off disc for stainless steel, high-speed steel and other profiles and grooves by grinding to the required dimensional accuracy. In recent years, Germany, the United States, Japan, and Switzerland have developed a series of special slow-moving and forming grinding machines, and the famous products have also been supplemented with the general use of the grinding function c DC motor and rolling screw, which has promoted the slower use. The practicality of feeding. China’s research and application of gradual advancement has also achieved remarkable results:

Slow feed to grinding. The grinding wheel and the outer edge of the workpiece are only contacted once or several times, and the chance of impact is less than that of the general reciprocating grinding, which can extend the durability of the grinding wheel and maintain its forming precision. After full-depth forming and grinding, a certain reciprocating grinding can be combined to combine the full-depth forming coarse grinding with the small heat-load finishing grinding to improve the grinding precision.

The characteristic of deep-cutting and deep-grinding is that the grinding wheel and the workpiece are in contact with the arc and the chip is long. The surface burn phenomenon of the workpiece should be avoided: the workpiece feed speed is very low during deep grinding, which is relatively small in the radial wear rate of the relative position of the grinding wheel. This is a great advantage for the rough and tip-grinding workpieces.

  The grinding depth of the grinding wheel is about 1000 times larger than that of ordinary grinding, and the grinding force is 2-4 times higher than that of ordinary grinding (at the same metal removal rate).
