The present invention relates to the technical field of precision machining tools, and discloses a diamond cutting tool for machining hard, brittle and difficult-to-machine materials. The material of the cutting edge portion of the cutting tool is polycrystalline diamond, and the cutting edge portion includes an integrally formed cutting body and a plurality of cutting edges. The cutting edges are spiral, and each cutting edge is circumferentially arranged on the outer surface of the cutting body along the central axis of the cutting body, and a first chip removal groove is arranged between two adjacent cutting edges; the first end of the cutting edge is arranged on the front end face of the cutting body, and the second end of the cutting edge is arranged on the side of the cutting body. The beneficial effects of the present invention are: by integrally forming a cutting edge on the cutting body of polycrystalline diamond material, compared with traditional welded sheet PCD cutting tools, a larger number of cutting edges can be arranged on the cutting body of the same outer diameter, and the shape and structure of the cutting edge are more diversified, thereby improving the cutting effect and machining efficiency, and extending the service life.

The application discloses a brake disc outer edge grinding mechanism and a grinding equipment. The outer edge grinding device is configured to include first and second grinding wheels which are arranged in a staggered manner. The first grinding wheel is arranged to be movable in the transverse and longitudinal directions, and the second grinding wheel is arranged to be movable in the transverse, longitudinal and lifting directions. The first and second grinding wheels can respectively perform first and second grinding on the outer edge through transverse and lifting movements to form first and second step structures, and then the longitudinal movement is used to complete the outer edge grinding operation. Thus, the outer edge grinding device can realize twice grinding on the outer edge through one feeding, the feeding amount is increased, and the grinding efficiency is improved.

The invention belongs to the technical field of sealing valves, and particularly relates to a transverse bench press sealing valve which comprises a valve body, two ventilation cavities are symmetrically formed between an outer ring and an inner ring of the valve body, plugging openings are formed in one sides in the ventilation cavities, two butt-joint openings are symmetrically formed in one end of the valve body, and the two butt-joint openings communicate with the two ventilation cavities correspondingly. A switch mechanism is arranged in the ventilation cavity and comprises a movable rod, two sets of guide holes are symmetrically formed in the outer ring of the valve body, the movable rod is movably inserted into the guide holes, the valve head is fixedly connected with one end of the movable rod, the valve head is located in the ventilation cavity, and a sealing gasket fixedly arranged on the valve head in a sleeving mode and a switch in the valve body are driven by an air cylinder. And secondly, two groups of ventilation cavities are arranged in the device, and the two groups of ventilation cavities can independently cut off and recover gas circulation, so that the function of controlling gas to enter and exit from the heat accumulating type organic waste gas oxidation furnace is integrated, the diversity of the functions of the device is improved, and the practicability of the device is higher.
