High-precision processes and precision applications often require ball screws with an accuracy class of P3 and there is a commonly-held view among mechanical design engineers that this accuracy can only be achieved with ground-thread screws.

Now, Thomson offers ball screws with a lead accuracy class of P3 (12 µm / 300 mm) manufactured using our proprietary rolling process called Precision Screw Forming Technology (PST).

The advantage of Thomson's rolled P3 ball screws is while meeting the same precision as ground spindles, they cost up to 70% less.

Their high precision is achieved through several factors:

The selection of the raw material is to precisely defined specifications while our proprietary forming and subsequent heat treatment processes using the latest technology are crucial.

The rolling process also results in a stronger material grain structure, so that the screw has a higher fatigue strength and thus a longer service life compared to ground screws.
