Description
Technical Field
The invention relates to a grinding wheel, in particular to a PCD grinding wheel with an ordered microgroove structure and capable of machining a positive rake angle.
Background
Grinding is used as a precision machining technology, has the characteristics of high machining precision and good surface quality, and is widely applied to the field of precision machining and manufacturing. However, in the traditional grinding process, the abrasive particles are irregularly arranged on the working surface of the grinding wheel, and the geometric shapes and the sizes of the abrasive particles are inconsistent, so that the situation that the abrasive particles cut the surface of a workpiece with a large negative rake angle often occurs in the grinding process, the grinding force ratio is increased, the grinding energy is converted into the grinding heat energy at an accelerated speed, the grinding temperature is increased, and the quality and the grinding efficiency of the processed surface are affected; meanwhile, the space for containing chips of the grinding wheel is small, the abrasive particles have low cutting degree and are easy to fall off, the grinding wheel is easy to block, local high temperature is generated to damage the surface of a workpiece, and the service life of the grinding wheel can be also reduced.
In order to improve the grinding efficiency and the service life of the grinding wheel, the patent with the publication number of CN107962510A 'a CVD diamond grinding wheel with ordered and micro-structured surface', a layer of diamond film is deposited on the outer circumferential surface of the grinding wheel hub by a chemical vapor deposition method, then a pulse laser beam is adopted to process a large number of grinding units with staggered and orderly arranged microgrooves and waist-shaped top surfaces on the outer circumferential surface of the whole diamond film, the removal rate and the grinding efficiency of processed surface materials are improved, the holding force of the grinding wheel hub on the grinding units is increased, the service life of the grinding wheel is prolonged, but the single grinding unit is still processed with a zero front angle in the grinding process, therefore, the grinding efficiency and the quality of the processed surface cannot be improved better, and meanwhile, the circumferential spacing of the grinding units which are orderly arranged in the grinding process is up to 1 mm, which belongs to typical intermittent grinding, so that the generated periodic vibration also influences the integrity of the processed surface.
In order to improve the integrity of the machined surface and realize positive rake angle grinding machining, a patent with publication number CN105728961A, "a method for manufacturing a novel positive rake angle diamond grinding tool based on pulse laser machining", proposes a method for laser machining the positive rake angle of diamond abrasive particles. The single-layer large-particle diamond abrasive particles which are orderly arranged on the working surface of the grinding wheel are ablated by adopting a laser processing technology, so that the vertex angle of the diamond abrasive particles is smaller than 90 degrees, the grinding process is changed into positive rake angle grinding, the problem that the surface of a workpiece is cut by the traditional diamond abrasive particles with a large negative rake angle is effectively solved, the processing efficiency is improved, the damage to the processed surface is reduced, and the integrity of the processed surface is improved. However, in the process of laser processing of the large-particle diamond abrasive particles, due to the fact that the laser ablation temperature is too high, the large-particle diamond abrasive particles are partially graphitized inevitably, so that the abrasive particles are influenced to cut the surface of a workpiece at a positive rake angle, the quality of the processed surface is reduced, and meanwhile, once the stress of a single large-particle diamond abrasive particle is too large or concentrated, the whole large-particle diamond abrasive particle may fall off, the grinding efficiency is influenced, and even the service life of the grinding wheel is shortened.
In order to further improve the quality of a machined surface and improve the grinding efficiency, the patent of publication No. CN107243848A entitled "helical orderly-arranged fiber cutter capable of machining a positive rake angle and a preparation method thereof" prepares a matrix on a grinding wheel hub by pressing and sintering, machines orderly-arranged small holes on the matrix by adopting a drill bit, and then consolidates fibers of the positive rake angle in the small holes by epoxy resin, thereby realizing the cutting machining of the positive rake angle, further improving the quality of the machined surface and improving the machining precision; but since the cross-sectional dimension of the fiber is as high as 0.8 mm
0.8 mm, the number of the fibers per square centimeter on the surface of the cutter is only 14.26, so that the cutting depth of single fibers is very large, the processing precision is difficult to ensure, and the single fibers are inevitably broken once the stress is too large or the stress is concentrated, so that the service life of the grinding wheel is influenced, and the problem that the difficulty of the preparation process of inserting all the fibers into small holes one by one and consolidating the fibers is too large is not ignored.
