The advantages of ceramic grinding wheels are their natural porosity and good chemical stability, so they are suitable for dry and wet grinding, but ceramic wheels have poor elasticity and require a high sintering temperature, which limits their development. Resin wheels have the advantages of good elasticity and low sensitivity to shock, impact and side …
Preparation before use: 1. Special personnel are responsible for the grinder and frequently checked to ensure normal operation. 2. When replacing the new grinding wheel, the main power supply should be cut off. At the same time, check whether the grinding wheel is cracked before installation. If it is difficult to distinguish with the naked …
Classification of grinding wheels The grinding wheel can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel and natural abrasive superhard abrasive and (diamond and cubic grinding wheel boron nitride, etc.) grinding wheel according to the abrasive used; Diamond wheel The diamond abrasive is used as the raw material, and metal …
Angle grinder, also known as grinder or disc grinder, is an abrasive tool used for FRP cutting and grinding. Angle grinder is a portable power tool that uses FRP cutting and grinding, mainly used for cutting, grinding and brushing metal and stone. The common models of angle grinders are divided into 100 mm (4 inches), …
1. The protective cover and protective plate (or protective net) of the grinder should be in good condition. 2. The grinder must be managed by the person in charge, and be checked and refueled frequently to ensure normal operation. 3. Goggles must be worn during use.

1. Before installing and using the grinding wheel, it must be visually inspected, depending on whether it has cracks or damage, and hit the grinding wheel with a wooden hammer, the sound should be crisp. Before use, the rotation test should be carried out according to the GB/T2493 standard, otherwise, the use is strictly prohibited …
Straight wave vibration marks appear on the surface of the workpiece: cause 1. The grinding wheel is unbalanced and the vibration is caused by the rotation; 2. The hardness of the grinding wheel is too high; 3. The wheel was not repaired in time after it became dull; 4. The grinding wheel has been repaired …

1. The choice of abrasive (the choice of abrasive mainly depends on the workpiece material and heat treatment method) When grinding materials with high tensile strength, use abrasive materials with high toughness. When grinding materials with low hardness and high elongation, use brittle abrasives. When grinding materials with high hardness, use abrasives with higher hardness. …
