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 â?¤ HRA88. PCD Tools are mostly used for finish turning cylinder, chamfering and engraving.
Models: RNMN solid CBN, RCMX soilid CBN, PCD notching tools, PCD engraving tools
Applications of PCD inserts, solid cbn : high speed steel (HSS) roll, Ni-Cr alloy cast iron roll, chilled cast iron roll, threaded steel roll, cast iron rolls, cast steel rolls, tungsten carbide ring, forged steel cold Rolls

1ã??PCD and PCBN Tools for Rolls Machining
Moresuperhard solid CBN inserts and PCD tools for machining high hardness rolls, cast iron roll, high-speed steel (HSS) roll, Ni-Cr alloy cast iron roll, chilled cast iron roll, threaded steel roll, cast iron rolls, cast steel rolls, tungsten carbide ring, forged steel cold Rolls. Due to its excellent properties, carbide rolls are widely used in the steel industry and their hardness is very high. For the machining of cemented carbide rolls, CBN/PCD Inserts can effectively replace the grinding process to improve production efficiency.
The roll is the main workpiece and tool that makes the metal continuously plastically deform on the rolling mill. The roll is mainly composed of three parts: roll body, roll neck and roll head. The roll is the intermediate part of the roll that actually participates in rolling the metal. Has smooth cylindrical or grooved surfaces. Rollers are almost universally used in nearly every manufacturing process in the world. The roller is the main part of the rolling machine, with the pressure which come from the rolling roller to roll the steel.

PCBN
PCBN consists of CBN and Binder. It is produced in high pressure and high temperature. It has excellent performance in hardness, wearing resistance, thermal stability.
Application: for hard ferrous materials (hardened steel, cast iron, high-temperature alloy, HSS, Powder metallurgy metals, Ni-Cr alloy...
E-Grind provides two series of PCBN:
1)Solid CBN
2)CBN with Tungsten Carbide supporting. "
MoreSuperHard PCBN inserts have excellent performance in processing gray cast iron, nodular cast iron, hardened steel and sintered metal.
Details:
PCBN inserts are compound super-hard material of polycrystalline cubic boron nitride layer and tungsten carbide sintered under ultrahigh pressure and high temperature. The hardness of PCBN is second only to diamond.
Advantages Of PCBN Inserts:
* Strong corrosion resistant, perform a good thermal stability and red-hardness
* CBN cutting tools have properties which resist chipping and cracking and provide uniform hardness and abrasion resistance in all directions. They may outperform conventional cutting tools by as much as 50 times.
* The high chemical stability allows for PCBN to be stable up to 1000° C and no reaction with Fe, Ni, CO etc
* Cutting hard and tough Materials. CBN cutting tools are so hard that they can efficiently machine steel with hardness of Rc 45 and above
* Easy grinding and EDM cutting. Uniform surface finish, surface finishes of less than 10 micron

From More Super Hard, you can get a PCD reamer with high accurate, reliable quality and economic to solve your problems in bores machining. Simple PCD reamers, customized multiblade stepped reamers and on to customer specific special tools are all available.
The reamer is a rotary tool with one or more teeth used to remove the thin layer of metal on the surface of the machined hole. The reamer has a rotary finishing tool with a straight edge or a spiral edge for reaming or trimming.
Reamers usually require higher machining accuracy than drills due to less cutting volume. They can be operated manually or installed on a drilling machine.
PCD reamer features: 1. PCD reamer has the characteristics of high processing accuracy, high processing efficiency, strong wear resistance and thermal conductivity, and strong toughness. 2. PCD reamer can realize high-speed cutting and cutting of hard materials. 3. The surface roughness of the workpiece processed by PCD reamer is better than that of ordinary cemented carbide reamer. 4. Our PCD reamer has a long service life. Its service life is 10 to 20 times that of ordinary cemented carbide reamer.

The reamer is a rotary tool with one or more teeth to cut the thin metal layer on the processed surface of the hole. The holes processed by the reamer can obtain accurate size and shape. The reamer is used to ream the drilled (or reamed) hole on the workpiece, mainly to improve the machining accuracy of the hole and reduce the roughness of its surface. It is a tool used for hole finishing and semi-finishing, The machining allowance is generally small. Reamers used to machine cylindrical holes are more commonly used. The reamer used to process tapered holes is a tapered reamer, which is less used. According to the use situation, there are hand reamer and machine reamer, and machine reamer can be divided into straight shank reamer and taper shank reamer. The hand type is straight-handled.
Reamer:
There are two kinds of coarse reamer and fine reamer. Coarse reamer has fewer blades and larger chip holding space. Meanwhile, a spiral chip dividing groove is opened on the blade to prevent excessive chip cutting and blockage in rough hinge.The number of blades of the reamer is large, and there is a small edge to ensure the quality of the taper hole.The specifications of common reamer are 1:50, 1:20 and 1:5.
