Typically rollers come to us from these industries:
- Asphalt Shingle Manufacturers
- Wire Drawing
- Fiber Optic Cable Production
- Steel Rolling Mills
- Aluminum Rolling Mills
Tungsten Carbide or Hard Chrome roll reconditioning.
People ask, how much tungsten do you want added. Frequently it is .006 – .008 inch.
The diameter tolerances on these rolls is usually tighter than other types of rolls.
Roughness values range from as high as 500+ Ra for traction coatings or finished down to 4 Ra.
When going higher than 500 Ra the surface roughness will exceed the capability of profilometers to measure.
Profilometers are instruments used to measure the roughness of a surface.
The finish pictured above is a 4 Ra.
Ra = Arithmetic Mean of Roughness
Ceramco has the capabilities to perfect the mirror finishes on these rollers.
