The main shaft of the vertical structure machine tool is vertically arranged, the grinding plate is horizontally arranged, the ball conveying mode is mainly an integral horizontal ball conveying disc, the main shaft of the horizontal structure machine tool is horizontally arranged, the grinding plate is in a vertical position, and the ball conveying disc is mainly an external horizontal or inclined disc.
When the spheres are machined by the two structural modes, two basic conditions for rounding the spheres are cutting probability and grinding size selectivity, wherein the cutting probability requires that each particle on the surface of each machined sphere has the same cutting probability, and the grinding size selectivity requires that large grinding balls are not ground or are ground less, and the long axis direction is ground or the short axis direction is not ground or is ground less during the machining process. The level of realization of these two conditions determines the level of precision of the machined ball, and also affects the efficiency of the machining of the ball.
For a machine tool with a vertical structure, a ball grinding plate is horizontally arranged, the grinding process is not influenced by the change of gravity and centrifugal force, pressure acts on the upper grinding plate through a group of springs to be flexibly positioned, so that the ground ball is uniformly stressed, good grinding size selectivity is realized, the geometric error of the ball can be corrected better and faster, the ball machining precision is higher, and particularly for hard and brittle materials such as structural ceramics and the like, the flexible machining technology can realize fine cutting on the surface material of the ceramic ball, so that the allowance can be removed in a plastic fracture mode, and an ultra-smooth and nondestructive surface is obtained. But the main problems of the current vertical structure machine tool are as follows: the balls are easy to accumulate at the ball outlet to generate dead angles, which affect the probability of cutting processing and the like, and the ball inlet quality and uniformity of the ball inlet are also further improved. In addition, the difficulty in chip removal is also a great disadvantage of the traditional vertical machine tool.
For a machine tool with a horizontal structure, the height difference of the openings of the grinding plates is fully utilized, the balls can be uniformly fed and smoothly discharged by means of an external horizontal or inclined material disc through the proper ball sliding angle and length of the ball feeding and discharging device, the balls automatically enter the grinding plates by means of self weight under the action of no external force, and the probability of cutting the balls is improved. Especially, the ball conveying mode of the inclined material plate further increases the ball sliding length and the ball storage stacking height, so that the high-efficiency and large-batch processing of the balls is realized.
