1: Zong Gangyu (A) features: high hardness, toughness. Application: suitable for grinding of medium and high tensile strength metal materials, such as general carbon steel, alloy steel, malleable cast iron, hard bronze, etc..
1. hardness is higher than brown corundum, toughness is slightly lower, grinding performance is good, grinding heat is small.
2. ordinary grinding for hardened steel, high speed steel, high carbon steel, high strength, high hardness materials, also can be used for processing screw thread, gear and thin-walled parts
3. grinding poor thermal conductivity of the workpiece and grinding tools, grinding wheel should be soft
4. used in inner circle, outer circle, plane, centerless, tool grinder and all kinds of special grinding machines, semi fine grinding
5. grinding wheels should be handled with care, to prevent vibration and collision, and prohibit rolling on the ground. When grinding wheel is stored, damp and cold should be prevented and the room temperature should not be lower than 5 degrees.
The general principle of choosing the hardness of grinding wheel is: when machining the soft metal, in order to make the grinding material not prematurely fall off, choose the hard grinding wheel. In the process of machining hard metal, a soft abrasive wheel is selected in order to make the worn abrasive particles fall off in time so as to expose the new abrasive (i.e. self sharpening) with sharp edges and corners. The former is because in grinding soft materials, grinding work of abrasive wear is very slow, do not need too early detachment; the latter because in grinding hard materials, grinding wheel abrasive wear to work faster, faster update.
In order to ensure the grinding accuracy and roughness, a slightly hard grinding wheel should be selected for fine grinding. The thermal conductivity of workpiece material is poor, it is easy to produce burn and crack (such as grinding hard alloy, etc.), the choice of grinding wheel should be soft.
