Rolls are almost universally used in every manufacturing process in the world. the roll is the main part of the rolling machine, will often add some metal element (such as chromium, nickel ... ) in the processing in order to make sure the usage lifetime and obtain the rolls durability. the materials of the rolls include, cast steel roll, cast iron roll, carbide roll and ceramic roll, etc.
During roll turning, cutting edge is to retain its sharpness over an extended period. It is also required to retain the toughness of the insert so that there is no failure of the tool on account of turning large roll diameters.
| Roll Material | Hardness (HS) | Cutting Conditions | ||
| V (m/ min) | F (mm/ Rev) | D (mm) | ||
| carbide | HRA81-86 | 5 - 30 | 0.1 - 0.3 | 0.1 - 0.5 |
| high speed steel | Over 85 | 20 - 50 | 0.1 - 0.3 | 0.1 - 2.5 |
| high speed steel | 70 - 85 | 50 - 80 | 0.1 - 0.4 | 0.1 - 3.0 |
| die steel | HRC 55 - 62 | 60 - 120 | 0.1 - 0.3 | 0.1 - 0.5 |
| Ni Grain Iron | 70 - 85 | 40 - 100 | 0.1 - 0.5 | 0.2 - 3.0 |
| High Chromium Iron | 70 - 85 | 40 - 100 | 0.1 - 0.5 | 0.2 - 3.0 |
| Chilled Iron | 65 - 85 | 40 - 100 | 0.1 - 0.5 | 0.2 - 3.0 |
| Nodular Iron | 40 - 70 | 50 - 120 | 0.1 - 0.5 | 0.3 - 3.0 |
| Steel Based Adamite | 40 - 60 | 50 - 130 | 0.1 - 0.5 | 0.2 - 3.0 |
The tool materials for machining rolls include carbide insert, ceramic inserts and cbn inserts. CBN insert is the hardest tool material for the processing ferrous metal materials and is the preferred tool for heavy duty cutting rolls.
More SuperHard company PCBN inserts have excellent performance, high fracture toughness and cutting edge strength , good balance of wear and fracture resistance in processing gray cast iron,nodular cast iron,hardened steel and sintered metal, etc.
