Every roll that leaves Arthur Rubber gets precision ground and polished to your spec. TIR (total indicator runout) verified. Surface finish to your Ra requirement. Crown grinding for paper machines and high-precision applications. The grind work is where great roll covering separates from average roll covering — and we've been doing it for 89 years.
Total indicator runout (TIR) is the measurement that matters most for high-speed roll service. We grind to your TIR spec, verify with precision instruments, document the readings in the shipping package.
Different applications need different surface finishes. Smooth polish for film and coating service. Coarser texture for grip applications. Specific Ra values for paper machines. We hold the surface finish you spec, not a generic 'finished.'
Crown grinding — engineered convex/concave profile across the face length — for paper machine rolls, calenders, and other applications where deflection compensation matters. Calculated and ground to your specific crown profile.
Diamond patterns, helical grooves, custom surface profiles cut into the rubber or urethane for specific applications (grip, fluid handling, embossing). Engineered with the same care as the underlying compound.
When the rubber cover touches a delicate substrate (film, coil coating, paper sheet), polishing matters as much as grinding. We polish to a Ra value that won't mark or transfer to the substrate.
Pre-grind measurements. Post-grind measurements. TIR readings. Hardness verification. All documented in the complete roll analysis package that ships with every order.
TIR tolerance, surface finish (Ra), crown profile, any special surface patterns.
After cure, rough grind to remove cover surface irregularities.
Final grind to your TIR and Ra spec on precision grinding equipment.
Polish where required. TIR verification with precision instruments, documented.
