Please refer to Figures 1-3, a plane milling grinding wheel includes a base circle 1, a stepped mounting groove 2, a diamond bit 3 and a semicircular arc 4; the base circle 1 is provided with a stepped mounting groove 2; a plurality of mounting holes are provided in the stepped mounting groove 2; the diamond bit 3 is evenly fixed to the lower surface of the base circle 1; the outer end of the diamond bit 3 is provided with a semicircular arc 4; a suspension frame 5 is detachably fixed to the mounting hole; a cleaning unit is provided on the suspension frame 5; when working, the diamond bit 3 is fixed to the lower surface of the base circle 1 in a circumferential manner, and the outer side surface of the diamond bit 3 is provided with a semicircular arc 4, so that the diamond bit 3 and the workpiece are in contact with each other. The contact surface circumference is larger, so that the semicircular cutter head is softer when in contact with the product, and there are no sharp corners at the moment of contact with the workpiece, which reduces the occurrence of scratches during processing. At the same time, the diamond cutter head 3 is small in size, easy to manufacture and easy to fix on the lower surface of the base circle 1 of different sizes, so that it can adapt to base circles 1 of different sizes, making it easier to manufacture grinding wheels of different sizes and models. At the same time, the diamond cutter head 3 with a semicircular arc 4 is more conducive to the coolant entering the grinding surface, taking away a large amount of heat while grinding, reducing product cracking caused by heat, and solving the problems of low grinding precision and poor heat dissipation effect of the existing grinding wheel.

The cleaning unit comprises a fastener 6, a connecting plate 7, an eccentric ring 8 and a brush 9; the fastener 6 is inserted into the suspension frame 5; the connecting plate 7 is movably sleeved on the fastener 6; the eccentric ring 8 is fixedly connected to the end of the connecting plate 7; the brush 9 is evenly fixedly connected to the lower surface of the eccentric ring 8; when working, the connecting plate 7, the eccentric ring 8 and the brush 9 are suspended and fixed by cooperating with the fastener 6 through the suspension frame 5, and are eccentrically connected to the ring composed of the diamond cutter head 3, so that they can move with the workpiece to achieve relative movement with the diamond cutter head 3, and fit the inner side of the diamond cutter head 3, thereby pushing the chips and cutting fluid on the inner side of the diamond cutter head 3 out of the diamond cutter head 3, so that there is only cutting fluid and only a small amount of chips in the contact movement range of the diamond cutter head 3 and the object, so that the grinding accuracy reaches the designed accuracy of the diamond cutter head 3, and solves the problem that the existing milling grinding wheel cannot discharge the chips in time, resulting in the grinding accuracy being lower than the designed accuracy of the diamond cutter head 3.

The diameter of the eccentric ring 8 is smaller than the diameter of the ring formed by the circumferentially fixed diamond bits 3; when working, the eccentric ring 8 contacts the product to be milled through the brush 9 on the lower surface, and then during the processing of the upper swing machine, the object to be processed moves with the brush 9 and the eccentric ring 8, thereby making a circular motion around the fastener 6, so that the grinding chips generated by the milling of the diamond bit 3 and the object are pushed out of the diamond bit 3. At the same time, the diamond bit 3 forms a ring shape, and the semicircular arc 4 is opened on the outer surface of the diamond bit 3, so that the semicircular bit when contacting the product is softer at the moment of contact with the workpiece, without sharp corners, and the occurrence of scratches is reduced during the processing, which solves the problem that the existing sharp bit has high friction and is easy to cause scratches when contacting the product.

The outer side surface of the eccentric ring 8 is tangent to the inner side surface of the diamond bit 3; during operation, the outer surface of the eccentric ring 8 is tangent to the inner surface of the diamond bit 3, so that the brush 9 fixed on the lower surface of the eccentric ring 8 can contact the inner side surface of the diamond bit 3, so that it moves along the movement of the object to be processed, and thus moves along the tangent on the inner side surface of the diamond bit 3, so that the cutting fluid and the chips are pushed out of the diamond bit 3 together, so that the chips will not accumulate on the inner side surface of the diamond bit 3, so that the space between the diamond bit 3 and the object to be processed will not be filled with chips, so that the milling efficiency is always maximized, and the moving brush 9 promotes the continuous movement of the chips and the cutting fluid, so that they are fully in contact with the diamond bit 3, thereby taking away the heat and the chips, so that the diamond bit 3 will not heat up too high to cause the product to crack during grinding, and reduce the deformation of the diamond bit 3 due to thermal expansion and contraction caused by heat, thereby solving the problem of low heat dissipation efficiency of the existing grinding wheel during grinding, resulting in low precision and product cracking.

The suspension frame 5, connecting plate 7 and eccentric ring 8 are made of plastic. When working, the suspension frame 5, connecting plate 7 and eccentric ring 8 made of plastic are lighter and have lower density, so that they will not cause wear when contacting the object to be processed, so that they can keep themselves cleaned from chips and cutting fluid without causing harm.

By adopting the above scheme, when the utility model is in use, the circumference of the diamond cutter head 3 is fixed on the lower surface of the base circle 1, and the outer side surface of the diamond cutter head 3 is provided with a semicircular arc 4, so that the circumference of the contact surface between the diamond cutter head 3 and the workpiece is larger, so that the semicircular cutter head when contacting the product is softer at the moment of contact with the workpiece, without sharp corners, and the occurrence of scratches during processing is reduced. At the same time, the diamond cutter head 3 is small in size, easy to manufacture and convenient to fix on the lower surface of the base circle 1 of different sizes, so that it can adapt to base circles 1 of different sizes, making it easier to manufacture grinding wheels of different sizes and models. At the same time, the diamond cutter head 3 with a semicircular arc 4 is more conducive to the coolant entering the grinding surface, taking away a large amount of heat while grinding, reducing the product cracking caused by heat, and solving the problems of low grinding precision and poor heat dissipation effect of the existing grinding wheel. Problem: Through the combination of the suspension frame 5 and the fastener 6, the connecting plate 7, the eccentric ring 8 and the brush 9 are suspended and fixed, and are eccentrically connected to the ring composed of the diamond cutter head 3, so that they can move with the workpiece to achieve relative movement with the diamond cutter head 3, and cut into the inner side of the diamond cutter head 3, thereby pushing the chips and cutting fluid on the inner side of the diamond cutter head 3 out of the diamond cutter head 3, so that there is only cutting fluid and a small amount of chips in the contact movement range between the diamond cutter head 3 and the object, so that the grinding accuracy reaches the accuracy designed by the diamond cutter head 3, and solves the problem that the existing milling grinding wheel cannot discharge the chips in time, resulting in the grinding accuracy being lower than the designed accuracy of the diamond cutter head 3; the eccentric ring 8 contacts the product to be milled through the brush 9 on the lower surface, and then the object to be processed carries the brush 9 during the processing of the upper swing machine The brush 9 and the eccentric ring 8 move, thereby making a circular motion around the fastener 6, so as to push the grinding chips generated by the diamond cutter head 3 and the object being milled out of the diamond cutter head 3. At the same time, the diamond cutter head 3 is in the shape of a ring, and the semicircular arc 4 is provided on the outer surface of the diamond cutter head 3, so that the semicircular cutter head is softer at the moment of contact with the product, and there is no sharp corner, which reduces the occurrence of scratches during the processing, and solves the problem that the existing sharp cutter head is easy to produce scratches due to high friction when contacting the product; the outer surface of the eccentric ring 8 is tangent to the inner surface of the diamond cutter head 3, so that the brush 9 fixed on the lower surface of the eccentric ring 8 can contact the inner side surface of the diamond cutter head 3, so that it moves along the movement of the workpiece to be processed, so as to move along the tangent on the inner side surface of the diamond cutter head 3, so as to push the cutting fluid and the chips out of the diamond cutter head 3 together. The diamond cutter head 3 prevents chips from accumulating on the inner side of the diamond cutter head 3, so that chips will not be filled between the diamond cutter head 3 and the object to be processed, so that the milling efficiency is always maximized, and the moving brush 9 promotes the continuous movement of chips and cutting fluid, so that they are fully in contact with the diamond cutter head 3, thereby taking away heat and chips, so that the diamond cutter head 3 will not be overheated to cause the product to crack during grinding, and the deformation of the diamond cutter head 3 due to thermal expansion and contraction caused by heat is reduced, solving the problem of low heat dissipation efficiency of the existing grinding wheel during grinding, resulting in low precision and product cracking; the suspension frame 5, connecting plate 7 and eccentric ring 8 made of plastic make it lighter and lower in density, so that it will not cause wear when contacting the object to be processed, so that it can keep itself cleaning chips and cutting fluid without causing harm.
