With the continuous development of the abrasive industry, the demand for grinding wheel sheet is increased. The flap wheel sheet can be divided into the flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup grinding wheel, dish grinding wheel, and so on. According to the binder, it can be divided into the ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel, and so on. The main characteristic parameters of the grinding wheel are abrasive, viscosity, hardness, binder, shape, and size. Today we'll see how to choose a good grinding wheel and how to install it.
The diameter of the grinding wheel blade used in high-speed steel saw blade grinding machine is 150 mm, and the aperture is 25 mm. The thickness of the grinding wheel blade depends on the tooth type and pitch of the saw blade. The material of the grinding wheel sheet is selected according to the material of the saw blade. According to experience, the particle size is between 60 and 100, and the hardness is between K and N. The grinding wheel sheet mainly adopts the ceramic sintering method. Other grinding wheel sheets, such as resin and rubber bonding methods, are also widely used. It is very important to choose good quality and stable grinding wheels in various situations.
A set of grinding wheel plate clamping cover and intermediate protective sheet are attached to the new machine when it leaves the factory. The intermediate shield is made of a strong and elastic black rubber. Its function is to make an elastic connection between the grinding wheel sheet and the clamping cover.
The thickness of the grinding wheel sheet is selected according to the type and pitch of the teeth to be ground. The thickness of the grinding wheel sheet used by the arc teeth is about 1/2 of the pitch to be ground. The shaped side of the grinding wheel sheet used by the arc teeth is semi-circular. The thickness of the grinding wheel sheet used by the triangular teeth is about 1/3 of the pitch to be ground, and its shape side is an acute angle.
Before loading the grinding wheel sheet, it is necessary to check whether the grinding wheel sheet is damaged or not. When loading the grinding wheel sheet, it is necessary to confirm that there is no difficulty in installation. It is also necessary to pay attention to the gap between the aperture of the grinding wheel sheet and the clamping cover of the grinding wheel sheet should not be too large, otherwise, the grinding wheel sheet will produce deviating centrifugal force and cause great vibration and noise. The grinding wheel sheet should be rotated for several minutes after installation, during which no one is allowed to enter the dangerous area.
