Application considerations trapezoidal screw and trapezoidal screw for lubrication, the rolling process is better than cutting (lathe milling) process. Because the rolling surface of the screw even more robust and better surface finish, trapezoidal screw imports, in addition, the rolling process can be used to deal with a long bar, and can be cut to any length. Precision rolled ball screw is better than 0.003 inches per foot can. For greater precision, you should consider using grinding processes. Ground screw can achieve .0003 inches per foot or better accuracy. However, the cost is much higher grinding process (10 times) Recommendations for Change Nut oil lubrication, especially oil-bath lubrication or drop lubrication is more effective. Oil-bath lubrication is the most appropriate method, because this method can meet the harsh conditions, such as high-speed, heavy load or external heat transfer, and the Change Nut cool. Drip lubrication for low to medium speed and in light load. Please select lubricants under the conditions shown in Table 2. Acme screw test there are several ways the most sophisticated trapezoidal screw as a rotating member, the gap is very small, which is a method of controlling precision acme screw, let us take a look at acme screw Inspection Methods. First, there must press opening is ground into a round flat shovel, dial indicator with a table stand, one side of the mold with a circular opening is ground into a round flat shovel must and trapezoidal screw bottom diameter of the cylindrical fit each other, the first school for manual straight, and one side with a round mold is required and trapezoidal screw cylindrical fit together, so the first is used for straightening presses a. If some of the alignment of the screw, it is best to use the manual alignment method, as the screw is placed on top of the U-shaped piece of iron, the opening round of the flat shovel and ground screw on the most prominent orientation, using a sledgehammer were hit, as were the dial indicator alignment, repeated many times. Second, if it is carried out, then the whole bending, small press to advocate the use of straightening, first trapezoidal screw placed two U-shaped iron above the side of a round mold directly on the screw was visually observed using a dial indicator alignment work performed, repeated several times. Third, Taiwan's imports of trapezoidal screw, in fact, does not require the use of any machine work table to support his assistant, all flat, due to the use of the lathe, then straightened difficult to achieve our ambition of effect, mainly because lathe in school straight division requires the use of a flame or carom, trapezoidal screw factory, trapezoidal screw will constitute a good influence owe, and in the process will show rotating centrifugal force. Recognition trapezoidal screw is required for some still is integral curved or bent Big Bend is still small, will eventually be recognized as straightening still use manual presses to straightening.
