Acme screw test several methods trapezoidal screw as the most sophisticated kind of moving parts, the gap is very small, which is a method of controlling the accuracy of, let us take a look at testing methods trapezoidal screw. First, there must press opening is ground into a circular flat shovel, dial indicator and table stand, one side of the mold with a circular opening is ground into a round flat shovel and trapezoidal screw must bottom diameter of the cylindrical fit each other, the primary school for manual straight, and one side with a round mold is needed and trapezoidal screw cylindrical fit each other, so the first is used for straightening presses a. If it is straight, then screw some school trapezoidal screw, it is best to use the manual alignment methods, like the screw is placed in a U-shaped piece of iron above, the opening round of the flat ground and shovel on the screw the most prominent position, using a sledgehammer were hit, like the dial were looking positive, repeatedly. Second, if it is carried out, then the whole bending, small press to advocate the use of straightening, first trapezoidal screw placed into two U-shaped iron above the ordinary trapezoidal screw, the side of the tire with a circular with directly on the screw, with the naked eye to observe the alignment operation performed using dial indicator, repeated several times. Third stainless steel acme screw, in fact, does not require the use of any machine work table to support all assisted plane, due to the use of the lathe, then straightening difficult to achieve our ambitions in effect, the first is due to the lathe straight in school Division requires the use of a flame or a carom, would constitute a trapezoidal screw trapezoidal screw factory owes a good influence, and in the process will show rotating centrifugal force. Admit trapezoidal screw is still a need for some overall bending, or Big Bend is still a small bend, will eventually be admitted that still use manual straightening presses to straightening. 8 screw - general driving, lathe and thread milling; major equipment: Roughing: CNC lathe 1M, 2M, 3M, lathe: 1M-8M lathes etc; semi-finishing: CNC lathe whirling: Finishing: 1M , 2M, 3M, 4M, 5M, 8M precision ball screw lathe, temperature processing, calibration foot indemnity six, seven, eight, nine different screw machining accuracy.
