Raw materials for oil stone production Electrofused alumina sand? How much purpose sand is used for the production of oil stone?
Fine-grained oil stones can be used as honed oil stones and super essential oil stones. Honing processing has a unique effect on the processing of the inner surface of the cylinder, it is a high-efficiency grinding method that can make the processed parts obtain high precision, low roughness and high life, and is widely used in the processing of machinery manufacturing. Honing processing has small cutting pressure, low cutting speed, less heat, and almost no burn phenomenon on the surface of the workpiece and stress deformation layer on the surface to be machined after processing. Special machining can also use strong honing or create a flat-top mesh effect of the surface being machined.
Superfinishing is a processing method in which the ultra-essential oil stone is pressed against the processing surface at a certain pressure while the workpiece rotates at a certain speed, and the reciprocating oscillation movement is perpendicular to the direction of workpiece rotation; Super finishing is often used in the finishing process of bearing channel, it can reduce the roughness value of the bearing channel surface, improve the geometric accuracy of the bearing channel surface, reduce the groove error and the waviness of the channel surface, improve the physical and mechanical properties of the bearing channel surface, the working frequency, amplitude, pressure and workpiece speed of the ultra-essential oil stone work have a crucial impact on the processing quality, so the quality of the oil removal stone, the selection of operating parameters is also very important.
