Rolls are core components for rolling mills in steel, paper, aluminum, brass and copper industries. After long‑term heavy‑load operation, rolls suffer surface wear and profile deformation, which requires regular cylindrical re‑grinding to restore crown profile, roundness and superior surface finish.
Conventional grinding wheels often suffer fast wear, poor profile retention, frequent dressing & wheel change, thermal burn on roll surface and excessive downtime, pushing up overall production cost.
Moresuperhard develops and manufactures premium diamond and CBN superabrasive grinding wheels for roll grinding. With resin bond and vitrified bond options, we deliver complete application‑oriented solutions for various roll materials. Our wheels greatly boost grinding efficiency, extend service life, and consistently secure tight geometry tolerance and fine surface finish, compatible with mainstream roll grinders including Herkules, Valmet and more.
| Roll Material | Recommended Abrasive | Recommended Bond | Key Features & Moresuperhard Performance |
| Rubber Rollers / Rubber Cover Rolls | Green / Black Silicon Carbide (GC / C) | Resinoid Bond (B) | High‑porosity structure to prevent clogging and improve heat dissipation, avoid thermal damage to rubber surface |
| Polyurethane Rolls | Green Silicon Carbide (GC) | Resinoid (B) / Rubber Bond (R) | Coarse grain & large‑structure formula for low‑speed grinding, minimize chip sticking |
| Thermal Sprayed Ceramic Rolls | Synthetic Diamond (SD / MD) | Resinoid (B) / Vitrified Bond (V) | High‑hardness diamond grit delivers sharp cutting, maintains high‑gloss roll surface with low wear rate |
| Chilled Cast Iron / High‑Chrome Rolls | CBN / SG Ceramic Alumina | Vitrified Bond (V) | Excellent wear resistance and chemical stability against ferrous metals; sustain crown profile accuracy and reduce dressing cycles |
| Tungsten Carbide Roll Rings | Synthetic Diamond | Vitrified Bond (V) | High self‑sharpening performance; stable retention of R‑corner and groove geometry, custom for OD & groove grinding |
| Forged Steel / High‑Speed Steel (HSS) Rolls | CBN / Microcrystalline SG Alumina | Vitrified (V) / Resinoid Bond (B) | High G‑ratio, prevents thermal burn on steel rolls, lengthen dressing intervals and cut downtime cost |
Compared with traditional alumina / silicon carbide wheels, our superabrasive wheels bring tangible production‑side benefits:
Proper wheel selection is critical for better quality and lower cost in roll re‑grinding. Moresuperhard diamond and CBN grinding wheels cover rubber, PU, high‑chrome cast iron, carbide, HSS and thermal‑sprayed ceramic rolls. We provide full technical support from abrasive‑bond selection to custom wheel manufacturing.
If you are troubled by low grinding throughput, roll burn, unstable profile or short wheel life, please contact Moresuperhard for your tailored roll‑grinding solution.
