Reasonable adjustment of the amount of ball in and out of the machine tool, the uniform depth of the R arc of the disk is the key to obtain the ideal spherical error and surface quality of the stainless steel bearing ball. In terms of entering and leaving the ball, the vertical machine tool can basically ensure that the number of stainless steel bearing balls that enter the channel and is ground in unit time is proportional to the channel center diameter by adjusting the in and out ball, that is, the depth of the groove R arc can be basically be consistent.
At the same time, according to the characteristics of the machine tool, the vertical machine tool completely enters the tray by the backward steel ball when it is out of the ball. It is inevitable that the time for the steel ball to stay at the ball outlet and the exchange of the steel ball have obvious differences, so that the quality of the steel ball There is a big difference in accuracy consistency. Therefore, the vertical machining machine needs to reduce the vibration and noise, and the key point of ensuring the uniformity of the R arc of the groove is to ensure the smooth and full exchange of the steel ball at the ball outlet.
While the horizontal machine tool enters and exits the ball, the number of steel balls that are ground in each channel per unit time is basically equal, that is, the weight of the steel ball scraped per groove per unit time is basically equal, and the inner groove is smaller than the outer groove. The groove diameter is short, so the inner groove is easier to grind than the outer groove. In terms of the ball exit, the processed steel ball smoothly flows into the tray under the guidance of the ball-receiving blade. At the same time, each time the tray is rotated, the steel balls inside and outside the tray are exchanged once.
Therefore, the horizontal machining machine should reduce the vibration and noise, and ensure that the R arc depth of the groove is consistent. The key point is to ensure that the stainless steel bearing ball is proportional to the length of the groove according to the length of the groove. Reduce the number of grooves to reduce the length difference between the innermost groove and the outermost groove.
