The dressing wheels are used for dressing diamond and CBN wheels. According to the different particle size, accuracy of the diamond and CBN grinding disc to choose the dressing wheel, making dressing easier and more time saving.

In addition to the standard, according to the American standard, the grit size ranges from 60 to 325, and the fine powder grade ranges from 400 to 14000. Please refer to the following table.

The camshaft on the automobile engine has multiple cams, and the rough grinding and fine grinding of the cam after quenching are the key processes that affect the quality of the cam. In general, imitative grinding is used, and the speed of the workpiece is limited, and the workpiece is prone to grinding burn cracks.

Grinding of guide parts often requires strict control of its profile and roughness. Whether in car pulleys or in complex bearings such as double guide ball bearings, the clearance accuracy and matching rate of the final product often directly affect the customer’s Production and user experience. However, it is clear in the industry that after the grinding wheel is manufactured, it is necessary to perform dressing to grind the workpiece to ensure the accuracy of the workpiece.

In the grinding process, under the action of friction and extrusion, the edges and corners of the grinding wheel gradually become blunt, or when grinding the ductile material, the grinding chips are easy to embedded in the pores of the grinding wheel surface, causing the surface of the grinding wheel to be blocked, and finally causing the grinding wheel to lose its cutting ability

When the high-speed CBN grinding wheel is grinding the workpiece, we often find that there will be burns on the surface of the workpiece, which is related to the high-speed operation of the CBN grinding wheel. The main types of burns on the workpiece are linear or non-continuous linear; the grinding direction of the deformed grinding wheel shows two types of black spot-like burns.

The RS series manual universal grinding machine of Ewag have excellent performance in grinding superhard materials such as PCD tool edges for over 30 years. Ewag manual grinding machines are used to grind high-precision micro-tools made of carbide, steel or other materials. In addition, our machines can withstand the rational manufacturing and re-sharpening of polycrystalline diamond and carbide tools.

Sharpening is a process of sharpening the grains of a super hard grinding wheel. In this process, it is necessary to form a sharp cutting edge in addition to the binding agent between the grinding grains and the grinding grain of blunt grinding wheel, so that the grinding grains with strong grinding properties can be highlighted with the binding agent. Trimming must also remove tiny materials from the pores on the surface of the grinding wheel to prevent the increase of grinding force acting on the grinding wheel, which will cause vibration and burn on the surface of the parts.

The China International Machine Tool & Tools Exhibition(CIMES) will be held at the Beijing International Exhibition Center from September 7 to 11, 2020. CIMES is the largest international machine tool and tools exhibition since EMO in Germany and IMTS in Chicago, USA. It has been held in Beijing biennially since 1992, which has won great favor and support in both domestic and foreign manufacturing industry, equipment users and foreign trade circulation enterprises. After nearly 30  years’ development, CIMES has made huge progress concerning internationalization. Over 1,300 manufacturers from 32 countries and regions take part in every session, with on-site reports from over 200 domestic and overseas media.
