The utility model belongs to the technical field of deep-hole milling cutters, particularly relates to a composite-edge deep-hole milling cutter for machining an automobile crankshaft, and solves the problems that a cutting edge is abraded in a long-time use process, and the cutting edge, a tool bit and a tool bar are of an integrated connecting structure, so that the tool bit and the tool bar need to be replaced together when the cutting edge is replaced, and the machining cost is reduced. According to the technical scheme, the cutter comprises a cutter root base, a first cutter root is fixedly installed at the upper end of the cutter root base, a first cutter bar is fixedly connected to the upper portion of the first cutter root, a center shaft is fixedly arranged in the center of the first cutter root, and a cutting tool bit is installed at the upper end of the first cutter bar in a threaded mode; a tool bit mounting groove is formed in the connecting position of the first tool bar and the cutting tool bit, the tool bit mounting groove is located in the center of the first tool bar, and a tool bit connecting block is fixedly connected to the connecting position of the cutting tool bit and the first tool bar. The whole tool bit and the whole tool bar do not need to be replaced, so that the cost of a user is greatly reduced.

The utility model discloses a scale type diamond saw blade which comprises a saw blade base body, scales formed by diamond particles are arranged on the surfaces of the two sides of the saw blade base body, chip removal cooling grooves which are communicated with one another and are nonlinear in direction are formed between the scales, and the scales are sequentially increased from a center hole to the side edge direction of the saw blade base body. According to the diamond saw blade disclosed by the invention, the diamond grains form a plurality of scales higher than the surface of the saw blade base body, and chip removal cooling grooves which are communicated with one another and are nonlinear in direction are formed among the scales. According to the chip removal cooling groove formed by the scales of the irregular structure, heat and waste chips in the saw cutting process are rapidly discharged out of the scale area from the multiple outlets through the non-linear structure, rapid heat dissipation and chip removal are achieved, and heating of the saw blade base body is reduced. And through the circumferential surface sawing surface, the workpiece can be rapidly slotted in the sawing process, and the sawing of the workpiece is accelerated.

The interior wall grinding device comprises a movable base, a handrail support and a grinding mechanism, walking wheels are installed on the front side of the bottom end of the movable base, fixed wheels are installed on the rear side of the bottom end of the movable base, the handrail support is installed on one side of the movable base, and the grinding mechanism is installed on the front side of the upper end face of the movable base. The grinding mechanism comprises a mounting base, a lifting assembly and a grinding assembly, the lifting assembly is mounted between the mounting base and the upper end face of the movable base, and the grinding assembly is mounted on the upper end face of the mounting base. And the construction efficiency can be improved.

The application provides a recessed root-milling grinding head and belongs to the field of precision machining. The grinding head is composed of an outer base body and a diamond ring. The outer base body and the diamond ring are both internally hollow and are provided with a through hole from top to bottom. The lower end of the outer base body is connected with the diamond ring. The lower end of the inner base body extends into the outer base body and is connected to the inner wall of the outer base body through a vane wheel. A water storage area is a space area formed above the vane wheel between the outer base body and the inner base body. The water storage area is connected with the outside through the gap between the upper end of the outer base body and the inner base body. The diamond ring is connected by a plurality of tooth-like structures. The diamond ring is also provided with an inner water groove and an outer chip removal groove. The device realizes the conversion from the external cooling mode to the internal cooling mode and guarantees the smooth flow of water. The water storage area provides temporary water storage, so that the water is more easily taken to the grinding work area during the rotation of the vane wheel, the grinding performance is improved, the tooth-like structure of the diamond ring can achieve one-time machining, and the root-milling treatment is not needed, thereby greatly reducing the cost.

The invention relates to the technical field of edible mushroom production equipment, and discloses an automatic bag cultivation pilose antler mushroom cutting machine which comprises a rack, a main conveying line is installed at an inlet of the front face of the rack, a belt conveying unit installed in the rack is arranged above the main conveying line, and the belt conveying unit extends to the outer side of the rack from the side face of the rack; a band saw cutting mechanism is arranged on the side, located in the rack, of the belt conveying unit and located over the main conveying line. By arranging the main conveying line and the belt output unit and arranging the band saw cutting mechanism at the space intersection of the main conveying line and the belt output unit, automatic cutting of the bag-cultivated velvet antler mushrooms can be achieved, cutting-off and transferring of the bag-cultivated velvet antler mushrooms can also be achieved, the harvesting efficiency of the bag-cultivated velvet antler mushrooms is greatly improved, the labor intensity of workers is reduced, and the labor intensity of workers is reduced. Meanwhile, the contact between a human body and a cutting tool can be reduced, and the safety of production operation is improved.

A kind of left auricle occluder framework high-speed electric spark milling processing manufacturing method.First, the shell with the initial form of left auricle occluder framework is prepared by base, upper casting mold, middle casting mold and lower casting mold casting, then the hole for fixing is processed to the shell by drill bit, and then the excess material on the shell is removed by high-speed electric spark discharge milling through the method of high-speed electric spark milling processing on multi-axis linkage electric spark machine tool, the mesh framework semi-finished product with the shell of the part to be processed barb is processed, and the barb is processed using the same high-speed electric spark milling processing method, and the heat treatment memory shaping is carried out through product shaping upper mold, product shaping middle mold, product shaping lower mold and base etc.Finally, the manufacturing is completed after cleaning.The high-speed electric spark milling processing manufacturing method improves the precision, surface quality and consistency of the occluder framework processing, does not need to process special electrode, improves the processing efficiency, reduces the processing cost, solves the problem that left auricle occluder framework cannot be integrally formed and manufactured, and can realize the individual customization of left auricle occluder framework in any form.
