Rolling Ball Screw

Rolling ball screw has the following advantages:

1, Productivity is improved. Cold rolling all kinds of regulating screw, its productivity compared with cutting methods, can increase 2 to 10 times, such as the original cutting T28 × 5 four furrow plow adjusting screw takes about 30 minutes, cold rolling process maneuver takes about 3 minutes.

2, Good quality. Turning thread shape, thread surface roughness in ▽5 ~ ▽6, and metal fibers are cut off: cold rolled screw, roughness up to ▽ 9, metal fiber tissue distribution improved only a little portion is cut off, the surface fiber compaction, so the hardness, intensity has increased.

3, Machine tools simple, production faster. We use two old five blow lathes and one old 10 feet lathe, respectively fit with four specifications of cold rolling box. When rolling screw, and only then square turret lathes, small carriage and large carriage detached, cold box mounted on the saddle rolling work can be done. The accuracy requirement of the machine tool is not high. Less investment and quick effect. Rolling different specifications screws, replace different cold rolling boxes. When stopped rolling, remove the roll box, the lathe can be used for other turning work.

4, Reduce labor intensity, easy and convenient operation, apprentice beginner can also operate.

5, Saving workpiece of metal material and tool material. Because before rolling the blank diameter is pitch diameter of thread, in theory, can save metal materials.

Ball screw from the process point of view is divided into two major categories of rolling and grinding screw. Rolling screw due to its higher degree of process automation features, very suitable for mass production, but also from a technical point of view, the consistency of the product is higher than the grinding screw, the currently P4 level and below ball screws mostly use of cold rolling process, and from environmental protection point of view, rolling screw has more advantages.

Foreign rolling screw of the process is relatively simple, mostly made using batch pressing rolling, and then made into different lengths of ball screw according to the needs. Most of the ball screw thread pressing process the same at home and abroad, later a single rolling screw process is slightly different.
