Product Description

G3208-4——32mm Diameter Ball Screw

Ground Ball Screws and Cold Rolled Ball Screws:

Ball screws are categorized into two types: ground ball screws and rolled ball screws. For ground ball screws, the raceways are first machined into shape using a lathe tool, and then ground to the required dimensions and precision by a grinding machine. In contrast, cold rolled ball screws are formed by extrusion during the cold rolling process, with both ends directly processed to complete the manufacturing.
1. Cold Rolled Ball Screws

The key challenge lies in the large allowance at the bearing seat, coupled with high hardness after heat treatment. Traditional processes typically involve annealing first, followed by lathe machining, or adopting a grinding process.

2. Precision Ground Ball Screws

The main hurdle is thread cutting. After heat treatment, ground ball screws have a hardness of HRC 60-65. Conventionally, threads are formed by grinding, but this method suffers from low efficiency and a high rejection rate, which affects overall production progress.
