High-hardness wear-resisting polishing head material and efficient polishing device

Abstract

The invention discloses a high-hardness wear-resisting polishing head material and an efficient polishing device. The polishing head material is prepared from, by weight, 32-42 parts of silicon carbide, 4-6 parts of polyester fiber, 1-3 parts of magnesium chloride, 3-5 parts of calcium carbonate, 5-8 parts of raw talc, 4-8 parts of copper powder, 2-5 parts of bismuth powder, 2-4 parts of magnesiumcarbide, 3-6 parts of aluminum oxide, 2-4 parts of aluminum borate, 1-3 parts of methylcellulose, 1-3 parts of boron nitride, 1-3 parts of vinyltriethoxysilane, 1-3 parts of antioxidant and 5-10 parts of heat stabilizer. The polishing device is flexible and convenient and fast to use, the position of a polishing head and pressure between workpieces and an abrasive wheel can be controlled by rotating a sleeve before polishing, and therefore it is ensured that polishing is smoothly carried out; and the pressure between the workpieces and the abrasive wheel can be adjusted to the required valueby pressing or lifting up a transverse rod according to the workpieces with different thicknesses during polishing, and therefore it is ensured that polishing is smoothly carried out.

Description

technical field [0001] The invention belongs to the field of mechanical processing equipment, and relates to a high-hardness wear-resistant grinding head material and a high-efficiency grinding device. Background technique [0002] Grinding devices are widely used in finishing and surface polishing of workpieces. Existing grinding devices include fixed grinding devices and mobile grinding devices. The fixed grinding device is fixed on the base, and then the workpiece is placed on the grinding wheel for grinding. However, the existing The fixed grinding device cannot adjust the distance between the workpiece and the grinding wheel, and cannot adjust the pressure, so that the grinding quality is poor, the scope of application is narrow, and the cost is high. The mobile grinding device is manually held in the hand to grind the workpiece. As time goes on, the hand will be very sore and fatigued, which will reduce the grinding efficiency. At the same time, there may be accidents,...

[0002] Grinding devices are widely used in finishing and surface polishing of workpieces. Existing grinding devices include fixed grinding devices and mobile grinding devices. The fixed grinding device is fixed on the base, and then the workpiece is placed on the grinding wheel for grinding. However, the existing The fixed grinding device cannot adjust the distance between the workpiece and the grinding wheel, and the pressure cannot be adjusted, resulting in poor grinding quality, narrow application range, and high cost

The mobile grinding device is manually held in the hand to grind the workpiece. As time goes on, the hand will be very sore and fatigued, which will reduce the grinding efficiency. At the same time, there may be accidents, which is very unsafe.
