There are many classification methods of rolls, 

- The material of the roller have : cast steel roller, case iron roller, forged roller.

- Product type, there are strip steel rolls, section steel rolls, wire rod rolls

- Position of the rolls in the rolling mill series, there are billet rolls, rough rolls, finishing rolls, etc.

- Product function, there are scale-breaking rollers, perforated rollers, leveling rollers, etc.

- Product material, there are hot rolls, cold rolls, etc.

- Type of rolling mill, it is divided into flat rolls and grooved rolls (it is used for rolling large, medium and small sections, wire rods and blooming billets. Grooves are engraved on the roll surface to shape the rolling stock), special roll

When processing mill rolls, especially processing large scale steel iron roll, it often has irregular surface, sand inclusion, holes and other problems. In order to solve the above problems we should choose What PCD and PCBN Inserts for Turning Rolls ?

- The tools materials for machining rolls include pcd inserts, pcbn cutting tools and solid cbn inserts, etc

- Solid CBN Insert is the hardest tool material for the processing ferrous metal materials and is the preferred tool for heavy duty cutting rolls. The high hardness rolls, Moresuperhard recommend the Solid CBN inserts which can be used for large margin cutting. Compared with the carbide cutting tools, the Solid CBN insert has performance stable, good production efficiency, and low production costs. Tungsten carbide ring is also called tungsten carbide alloy roll ring ( WC rolls or TC rolls), we process them with CBN and PCD Tools .

- Normally, CBN Inserts are generally used for rough turning tungsten carbide rolls which hardness ≤ HRA88. PCD Tools are mostly used for finish turning cylinder, chamfering and engraving.

The specifications size of PCD tools, solid CBN inserts for machining roll

- Solid CBN inserts for Rolls Machining

As a PCBN inserts manufacturer and exporter in China, More Superhard's PCBN inserts have excellent performance in processing gray cast iron,nodular cast iron,hardened steel and material, sintered metal,and processing work piece surface is highly polished and very durable. Solid CBN iinserts rough machining high Ni-Cr alloy cast iron rolls, semi finishing chilled cast iron rolls, finish turning forged steel cold rolls,  turning tungsten carbide rings and hss rolls, etc
