The utility model relates to the technical field of machining centers, and discloses a machining center with a cutter grinding device, which comprises a machining table, a through groove, a mounting groove and a placing groove are formed in the inner side surface of the machining table, a sliding groove is formed in the inner side surface of the placing groove, and a cutter grinding mechanism and a clamping mechanism are arranged on the inner side surface of the machining table; the knife sharpening mechanism comprises an adjusting part and a cooling part; the cooling part is located on the top face of the adjusting part. According to the knife sharpening mechanism, a first motor in an adjusting part is used for starting the first motor, so that the first motor drives a first threaded rod, the first threaded rod drives a threaded block, the threaded block drives a supporting plate, a knife sharpener, a door-shaped branch pipe and a corrugated hose to descend, the knife sharpener is used for sharpening the knife, and a water pump is started while knife sharpening is conducted; the water pump pumps the water storage tank through the connecting pipe, and pumped water enters the corrugated hose through the branch pipe, is sprayed out from the door-shaped branch pipe, falls into the filter screen and finally enters the water collection tank, so that the water storage tank is cooled, the grinding temperature is reduced, and the cutter is prevented from overheating deformation.

The utility model discloses a high-speed grinding wheel for glass processing, and relates to the technical field of glass processing. Comprising a grinding wheel seat and a grinding wheel mounted at the top end of the grinding wheel seat and used for grinding. The outer cambered surface of the grinding wheel seat penetrates through the inner cavity of the grinding wheel and is provided with a plurality of groups of dewatering ports at equal radian, and the inner wall of the positioning bottom plate is provided with a plurality of groups of water distributing grooves corresponding to the dewatering ports. According to the high-speed grinding wheel for glass processing, through collaborative optimization of materials, structures and functions, the glass processing efficiency and quality are remarkably improved. By adopting the design of the high-strength diamond material, the silicon carbide and the ceramic abrasive, the cutting hardness and the thermal conductivity are guaranteed during high-speed operation, the stress concentration problem is relieved, and the overall service life of the grinding wheel is prolonged. Rapid circulation and throwing-out of the cutting fluid are achieved, the grinding temperature is effectively reduced, glass edge breakage or burning is avoided, and the surface smoothness under 12 m / min high-speed machining is ensured.

A bearing flange superfinishing grinding device with an automatic feeding function relates to the technical field of precision grinding equipment and comprises a square integrated base, a square grinding protection box is welded to the upper surface of the integrated base, a grinding operation table is fixed to the inner bottom surface of the grinding protection box, and an assembly mounting frame of a C-shaped structure is welded to the upper surface of the grinding operation table. An automatic feeding and discharging system and an ultra-precision grinding assembly are arranged in the grinding protection box. A clamping transfer assembly is further arranged in the grinding protection box. The problems that in the prior art, when the bearing flange is subjected to ultra-precision grinding machining, the production efficiency and the automation degree are low, the machining precision and stability are insufficient, the machining flexibility of a composite surface is poor, and the working environment and the integration degree need to be improved are solved.

The application belongs to the technical field of pipeline butt joint, and particularly relates to an auxiliary butt joint equipment for pipeline welding, which comprises a butt joint table, a supporting frame, a butt-sending type splicing mechanism and a heat-conducting type end grinding mechanism. The supporting frame is arranged on the two sides of the butt joint table. The butt-sending type splicing mechanism is arranged on the upper wall of the butt joint table. The heat-conducting type end grinding mechanism is arranged at the middle position of the upper wall of the butt joint table. The butt-sending type splicing mechanism comprises a clamping assembly, a driving assembly and a pushing assembly. The auxiliary butt joint equipment for pipeline welding can grind the end face of the pipeline before butt joint, improve the smoothness of the butt joint end face of the pipeline, reduce the splicing gap, keep the butt joint area and the surrounding surface of the pipeline dry, and improve the welding quality.
