Cutting chip experts explain the different characteristics of dry and high quality cutting disc supplier?
The use of lubricating fluids in the grinding process is called wet grinding, while the use of lubricating fluids is called dry grinding. Since the lubricating fluid has a good cooling effect, lubricating action and cleaning action, the dry grinding and the wet grinding have the following different characteristics.
1. When dry grinding, the heat dissipation condition is poor, the heat dissipation is slow, and the large grinding amount cannot be selected. When wet grinding, the heat dissipation conditions are better, the heat dissipation is faster, and the grinding amount can be selected to be larger.
2. During dry grinding, the workpiece is prone to annealing, cracking and thermal deformation due to the temperature rise of the workpiece and the instantaneous high temperature of the workpiece surface. During wet grinding, the grinding heat is removed by the lubricating fluid, which reduces the grinding temperature. The lubricating fluid also reduces the friction and washes away the falling abrasive grains and wear debris, thereby avoiding or reducing cracks and deformation of the workpiece and improving the workpiece. Accuracy and surface finish.
3. During dry grinding, the grinding wheel is easy to block the grinding wheel after melting, which makes the grinding wheel dull and the grinding wheel consumes a large amount. When wet grinding, the grinding wheel consumes less and improves the durability of the grinding wheel.
4. When grinding cast iron and bronze workpieces, in order to facilitate the use of vacuum cleaners to remove dust, dry grinding is generally used. When grinding the machine guide rails, dry grinding is usually used because of the inconvenience of using the cooling liquid.
5. When dry grinding, it is easy to observe the grinding condition of the workpiece surface, which is easy to operate and control. Therefore, dry grinding is usually used in tool sharpening.
