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. 1）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 2）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. 2、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 - PCD Notching Tools, PCD Boring Cutter for Roller The PCD notching tools, pcd boring cutters are made by PCD blanks (E6) brazing on the tungsten carbide body. Most common is full face pcd notching tools. PCD boring tools are used for machining various of tungsten carbide rollers. PCD tips for carbide roller notching. When machining rolls, the grooving tool sometimes breaks, which is generally due to the following reasons: Reason1.The tool holder and tool head are not well matched, the accuracy is not reached, and the tool is twisted during processing, resulting in tool fracture. Reason2.The strength of the tool holder is not enough, and the alloy matrix of the PCD notching tools is too thin, so the strength and toughness are not enough, leading to fracture in the process of use. Reason3.Unconventional fracture, for example, the positioning surface of the roller knife is not round, or there is a violent processing when processing. For these reasons, we propose the following solutions: Solution1.Control the precision of tool holder and tool head, pay attention to step by step when processing Solution2.Enhance the strength of the tool and increase the thickness of the alloy matrix. If the customer has certain requirements for thickness, you can make the diamond part as thin as possible, the alloy matrix thicker to enhance the strength of the tool. Solution3.The circular arc of the positioning surface of the PCD notching tools should be rounded. Not violent processing, should step by step.

Ceramic insert, Ceramic Cutting Tools

Description: Ceramic grade tools are typically classified into three general categories: oxide, nitride, and matrix ceramics. Oxide ceramics are alumina-based and are generally used in roughing and finishing applications of the cast and gray irons. Increasingly, oxide ceramics are being used in dry machining applications at high speeds. This is due to the advancements within materials science, including the incorporation of whisker-based materials. Nitride ceramics exhibit extremely high fracture toughness and are used for roughing and semi-roughing of cast irons under harsh conditions, such as when there is considerable starting and stopping that would typically increase fracturing. CMCs contain ceramics mixed with other hard materials like cemented and titanium carbides. They can also contain reinforcing whiskers and other materials to increase wear resistance and toughness under hot machining conditions. These are commonly referred to as SiC-whisker reinforced. Alumina reinforced with SiC whiskers is the toughest and most resistant to thermal shock of the oxide-based ceramics due to the extremely high tensile strength of the SiC whiskers. It offers the additional benefit of being able to be run without coolant, thus making dry machining a common application while also being able to offer an increase in machining rates up to 800%. Details Applications of Ceramic insert, Ceramic Cutting Tools : Auto parts processing A series of parts such as milling cylinder cover, cylinder sleeve, and automobile brake disc are processed with composite silicon nitride ceramic blade, which can improve the efficiency. For example, a milling cutter can increase its speed from 92r/min to 275r/min. Bearing machining The rolling bearing adopts the technology of rough, fine, quenching, rough grinding, and fine grinding for a long time. For example, after hardening to 63HRC, the blank of the GCr15 precision forging bearing will be deformed and uneven and will get stuck in the rough grinding of the automatic grinding machine directly, and even burn the spindle of the grinding machine in serious cases. The finishing process of the bearing ring before quenching and the rough grinding process after quenching are combined into the finishing process of the ceramic cutter after quenching, which will make the workpiece fully meet the required size and geometric accuracy, realize the substitution of grinding by car and greatly improve the processing efficiency. Hard cast iron processing If the composite nitride ceramic tool is used to process the cold cast iron roll, the tool life is increased four times than that of cemented carbide; it can be used to process superhard nickel alloy spray welding roller bushing, which can greatly improve the cutting efficiency and speed, save time and cost and improve economic efficiency. Other fields In the fields of machinery, metallurgy, mining, railway locomotive, aerospace, precision instruments, molds, etc., the technology can be reformed by using silicon nitride ceramic cutting tools to greatly improve production efficiency, save energy and reduce cost. Bearing machining Application Cases of Ceramic insert, Ceramic Cutting Tools : Advantages of Ceramic insert, Ceramic Cutting Tools : Compared with carbide cutting tools, silicon nitride ceramic cutting tools have obvious advantages, which are shown in the following aspects. ● The HRA value of silicon nitride ceramic cutter is usually 91-93 (HRA is used to represent the hardness index of soft and hard materials), so it has good wear resistance and can be used to process high hard materials that are difficult to be processed by traditional tools or cannot be processed at all, such as various kinds of hardened steel and hardened cast iron with the processing hardness up to HRC65 (60HRA = 20HRC). ● It can be used for rough and finish machining of high hardness materials, as well as for high-impact machinings such as milling, planning, and intermittent cutting. ● The cutting tools made of silicon nitride ceramics can be cut at high speed to realize the function of “milling for grinding” for high hard materials, simplify the processing technology and improve the processing efficiency, so as to save time, electricity, number of machine tools and plant area and other effects. ● The silicon nitride ceramic blade has less friction with metal when cutting, which makes it difficult to stick to the blade and the roughness of the workpiece is low. ● The tool’s durability is several times or even dozens of times higher than that of traditional tools, which reduces the number of tool changes during machining, ensures the uniformity of the workpiece, and also ensures small taper and high accuracy. ● The cutting tool consumes the most abundant element silicon in the crust as raw material, which can save a lot of strategic metal materials such as tungsten, cobalt, and titanium.
