Use a grinding wheel cutting grinder features are as follows:

    (1) Since the heat resistance of the cutting wheel  abrasive itself has high hardness, and therefore can be machined to a high hardness materials such as hardened steel, carbide, etc..

    (2) grinding wheel grinder characteristics determine the grinding process system for uniform micro-cutting, general ap = 0.001 ~ 0.005mm; grinding speed is very high, generally up to v = 30 to 50 m / s; good grinder stiffness; hydraulic transmission the grinding can be economically obtain high machining accuracy (it6 ~ it5) of small surface roughness (Ra = 0.8 to 0.2 μm). One of the main methods of grinding parts finishing.

    (3) Due to the intense friction of the grinding zone temperature is very high. This will cause the workpiece to produce stress and deformation, and even cause surface burns. Grinding injected a large amount of coolant to reduce the grinding temperature. The coolant also from the BTA-lubricating effect.

    (4) grinding the large radial force. This will cause the machine - grinding wheel - workpiece system flexibility concession, the actual depth of cut is less than the nominal depth of cut. Grinding to be completed should not feed for light grinding to eliminate errors.

    (5) self-sharpening: abrasive grinding blunt, grinding force gradually increases, causing abrasive broken or off and re-exposed sharp edge features. The self-sharpening of the grinding head to work correctly within a certain time, after a certain time required professionals to manual trimming, to prevent the increase in the grinding force to cause vibration, noise and damage the workpiece surface.

Sandpaper paper a special industrial paper market is relatively narrow, the amount is not less than 20,000 tons, the annual domestic market, with the accelerated process of China's industrialization, greater growth in recent years, but due to the special requirements of sandpaper paper, grinding wheel,market profits little space, the state little paper R & D and technical support, several state-run paper manufacturers originally planned economy completely disintegrated, closure or conversion, base paper production enterprises depleted, papermaking equipment production capacity is only Hubei Haifeng Paramount Paper, Paper Jiangxi several enterprises such as supporting the development of the industry.
Above the base paper production enterprises can basically meet the sandpaper manufacturers to select the paper needs, especially heavyweight belt paper latex paper, the original all rely on imports, the current domestic production of some products can basically replace imported. Of super-heavy production of ultra-precision grinding sandpaper paper paper-based belt paper, there is a certain gap between the process equipment with foreign, yet can not meet the requirements of coated abrasives production enterprises need to accelerate innovation, enhance research and development capabilities and manufacturing standards.cutting wheel
