The invention relates to the technical field of milling cutters, in particular to a wind driven generator rotor magnetic steel ladder groove machining milling cutter which comprises a milling cutter disc, a driving shaft and a first conveying unit. A plurality of groups of mounting grooves are formed in the outer edge of the milling cutter disc, and a cutting assembly is arranged in each group of mounting grooves. The cutting assembly comprises a cutting edge, the cutting edge is provided with a cutting face, and the cutting face is provided with a cutting end used for executing the cutting action. And when the driving shaft drives the milling cutter disc to axially rotate around the milling cutter disc, the cutting end starts deep groove machining immediately. After the cutting fluid in the containing cavity flows into the first flow channel, the first conveying unit can guide the cutting fluid to stably flow to the cutting end, so that the cutting end and the area, making contact with a workpiece, of the cutting fluid are efficiently cooled and lubricated. Therefore, through guiding of the first conveying unit, the flowing path of the cutting fluid on the cutting face is prolonged, the residence time of the cutting fluid on the cutting face and the cutting end is prolonged, efficient cooling and lubricating are achieved, the cutting temperature is remarkably reduced, and heating and abrasion of the cutting edge are reduced.

The utility model discloses a kind of wear-resistant tungsten steel milling cutters, including milling cutter assembly, cooling and flow guide mechanism, external clamping mechanism and clamping auxiliary mechanism, the cooling and flow guide mechanism includes outer fixed sleeve and cooling pipe, the external clamping mechanism includes clamping inner tube and clamping outer tube, the clamping auxiliary mechanism includes outer fixed clamping ring and outer rotating sleeve, cooling and flow guide mechanism is designed using outer fixed sleeve and symmetrical cooling pipe installation, so that coolant can be accurately guided to the cutting area of milling cutter assembly by water outlet pipe, effectively solve the high temperature problem of milling cutter in prior art, significantly reduce cutting temperature, through the ingenious cooperation of clamping inner tube, clamping outer tube and extension frame, the inconvenient problem of connecting and disassembling of cooling pipe and external liquid supply equipment is innovatively solved, the design of clamping groove and slope pressure groove makes the connection process more smooth, the design of screwing clamping plate control extension frame realizes quick locking and release, without special tool, operation can be completed.

The utility model relates to the technical field of CNC machining centers, and discloses a liquid die forging automobile swing arm CNC machining center device which comprises a base, a shell is fixedly connected to the top of the base, a clamping assembly is arranged in the shell and comprises a clamp, a first rotating shaft is fixedly connected to the interior of the clamp, and a second rotating shaft is fixedly connected to the interior of the first rotating shaft. A first linkage rod and a second linkage rod are rotatably connected to the outer wall of the first rotating shaft, a second rotating shaft and a second fixing column are fixedly connected to one end of the first linkage rod and one end of the second linkage rod, a sliding block is fixedly connected to the end of the second fixing column, a limiting block is slidably connected to the outer wall of the sliding block, and a fixing plate is fixedly connected to the outer wall of the limiting block. A first connecting column is fixed to the bottom of the fixing plate. According to the liquid die forging automobile swing arm self-adaptive clamping device, the problem that when a traditional CNC machining center device machines a liquid die forging automobile swing arm, a traditional clamp is poor in adaptability due to the fact that geometrical characteristics of a liquid die forging piece are complex is effectively avoided, and the effect of self-adaptive clamping of the liquid die forging automobile swing arm is achieved.

The utility model relates to a composite boring cutter with an adjustable blade position, which belongs to the technical field of composite boring cutters and comprises a boring cutter body, two open grooves are arranged on the periphery of the boring cutter body, a plurality of mounting areas are arranged on the periphery of the boring cutter body, fine adjustment cutter holders are arranged on the outer walls of the mounting areas, and sliding grooves are arranged inside the fine adjustment cutter holders. And a cutter bar is rotationally mounted in the fine adjustment cutter holder. The boring cutter body has the advantages that when the boring cutter body is used for machining a workpiece, the cutter bar can be driven to rotate through rotation of the transposition disc, meanwhile, the gear can be driven to rotate, and therefore the machining blade can move linearly under the action of the limiting assembly, and the purpose of fine adjustment of the machining blade can be achieved; and through the use of a locking bolt a, the fine adjustment tool holder with the position adjusted can be locked, so that the corresponding position of the machining blade can be adjusted according to different machining requirements, and the applicability of the boring tool body can be improved.

The present application relates to the technical field of metal cutting tools, and provides a micro-textured tool and a processing method thereof, which comprises a tool base body, a fan fin structure micro-texture, a raceway roller structure and a stepped structure are arranged on the tool base body rear face, a plurality of fan fin structure micro-textures are arranged close to the main cutting edge and the edge array of the tool base body, a plurality of stepped structures are equidistantly arranged on one side of the fan fin structure micro-texture, and two groups of raceway roller structures are communicated with the stepped structures and are arranged on the two sides of the stepped structures respectively. The fan fin structure micro-texture, the raceway roller structure and the stepped structure are matched with each other, which can not only promote the occurrence of derivative cutting and the quality of the processed surface, but also reduce the tool wear and prolong the service life of the tool.
