S45C Cold Drawn Grounded and Polished Bright Steel Round Bar
Turned, Ground, and Polished shafting starts with either a hot rolled or cold drawn bar being turned in a lathe where material is taken off. The turning continues until the steel bar is brought down to the desired size. Multiple passes may have to be made until the desired size is reached. After being turned, the surface condition is still relatively rough which could cause uneven wear and balancing issues. To remedy that, the bar is then ground with a grinding wheel to take a much smaller amount of material off. Once the dimensions of the bar are acceptable, it is then polished using a polishing wheel. This polishing process gives it the smooth surface finish required and it now has become a Turned, Ground & Polished shaft.
Advantages of the Turned , Ground and polished steel shaft:
Tolerance:
excellent tolerances as close as +0/-0.01mm on the diameter
Straightness:
Laiwu Xincheng Metal Co.,Ltd can supply Good straightness to 0.2mm/m due to its final application requirements.
Time Saving:
By getting the material already Turned, Ground and Polished, it saves a tremendous amount of time for the end user which allows them to focus on their business.
Cost Saving:
it allows you to save a tremendous amount of money that would otherwise be spent on equipment, labor, material, and time to produce in house.
