Description
Technical Field
The application relates to the technical field of deep hole machining, in particular to a deep hole grinding and polishing device and a using method.
Background
A hole in a deep hole process refers to a hole having a length to diameter ratio of greater than 6. In deep hole processing, the depth-diameter ratio L/d of a general deep hole is more than or equal to 100 under most conditions, such as an oil cylinder hole, an axial oil hole of a shaft, a hollow main shaft hole, a hydraulic valve hole and the like. Some of the holes have high requirements on machining precision and surface quality, and some machined materials have poor cutting processability, which often becomes a great problem in production.
For deep holes with high requirements on precision and surface roughness, fine boring, grinding or honing is generally carried out after semi-finishing. Spiral knife lines are left on the surface of the inner hole after boring, and the surface finish is poor. When a deep hole is ground, the machining precision of the hole is often difficult to ensure due to the large suspension depth of the grinding head, the large grinding force of the grinding wheel and the quick abrasion of the grinding wheel. The honing allowance is generally not more than 0.2 mm, and large allowance removal is difficult to realize; the honing process is easy to generate more heat and is difficult to radiate, so a large amount of grinding fluid is needed; the contact area between the oilstone and the workpiece is large, the gap is small, the surface of the oilstone is easy to block, accumulated cuttings are easy to scratch the surface of the workpiece, and heat dissipation is not facilitated; since excessive grinding heat easily affects the quality of the machined surface, this limits the enhancement of honing efficiency to some extent; finally, in order to realize the precision of honing processing, the honing head needs to be equipped with the U-axis function, so that the automatic adjustment of honing size is realized, but the high-precision U-axis depends on import at present, and the U-axis is expensive and inconvenient for later maintenance.
