The tool also comprises a coolant channel (38) which is arranged in the cutting plate carrier (12) and extends between an inlet opening (40) and an outlet opening (42), the outlet opening (42) leading into the through opening (34) and / or being oriented in the direction of the through opening (34).

A method for processing the surface roughness of a superhard laser crystal, the method comprising the steps of grinding, rough polishing, precision ring polishing and the like. The method of the invention strictly controls the grinding amount of each process in the grinding stage through the detection of the particle size of the abrasive, and fundamentally removes subsurface defects; by adding polishing aids, the polishing liquid is more uniformly dispersed and lubricated, thereby effectively controlling the surface The generation of subsurface defects greatly improves the surface roughness of superhard laser crystals. For Nd:YAG crystals with specifications of 125mm×6mm×6mm and 133mm×33mm×3mm, the roughness of the two large surfaces reaches 0.3nm.

The transmission mechanism has a transmission housing (12) with a wall (14), a bearing (16) for a rolling bearing (18) and / or a radial shaft sealing ring (20) being formed in the wall (14). According to the invention, a scraping rib (22) protruding from the wall (14) is formed on the wall (14), the scraping rib extending along a central longitudinal axis (24), the central longitudinal axis (24) of the scraping rib (22) intersects the support (16), and one or more recesses (26) are formed in the wall (14) between the scraping rib (22) and the support (16), the recesses extend between the scraping rib (22) and the support (16).

An oil-gas lubrication bearing pedestal with two-way nozzles comprises a floating bearing pedestal body and a fixed bearing pedestal body, and the floating bearing pedestal body and the fixed bearing pedestal body are arranged in parallel. A plurality of oil inlet pipelines are arranged in the fixed bearing pedestal body in the axial direction in a through mode. The oil-gas lubrication bearing pedestal further comprises an oil injection disc arranged between the two bearing pedestal bodies. A plurality of oil injection holes are annularly and evenly formed in the side, close to the fixed bearing pedestal body, of the oil injection disc. A plurality of oil ducts are formed inside the oil injection disc in the radial direction. The oil inlet pipelines, the oil injection holes and the oil ducts communicate in a one-to-one correspondence mode. The flow-out end of each oil duct is further provided with the corresponding nozzle in a communicating mode. The nozzles are divided into two groups with opposite oil injection directions, the numbers of the two groups of nozzles are equal, and the nozzles are evenly arranged in the circumference direction at intervals.
