With the development of the global economy and the advancement of industrialization, the demand for steel products continues to grow. Steel products such as steel plates, steel pipes, etc. are indispensable materials in modern industry and are widely used in construction, machinery manufacturing and other fields. At the same time, the steel industry is one of the main application areas of roll processing. In the steel production process, raw materials need to undergo multiple processes such as continuous rolling, heating and cooling through rollers, and finally form steel products of various specifications and shapes. Moresuperhard can provdie PCD notching tools, PCD engraving tools and CBN cutting tools for maching roll.

The steel industry continues to introduce new production processes and equipment in order to improve steel quality and production efficiency. this also provides a broad development space for the roll processing market. As a tool manufacturer, Moresuperhard also continuously develops new roller tools to solve and improve customers' requirements for cutting efficiency and processing accuracy. One link after another, they complement each other and help the development of the industrialization process.

The current difficulties in roll processing include:

·Heavy mass, large size, long cutting time, and low processing efficiency. 

Rolls that need to be turned are generally large in size and heavy in mass. Compared with ordinary cutting, there are problems such as large cutting depth, low cutting speed, and slow feed speed, which affect the processing efficiency and cause tool wear and rework.

·The roller has high hardness and is difficult to cut. 

In order to improve the hardness, wear resistance and thermal strength of the roll and prevent cracks in the roll, molybdenum, manganese, chromium and other elements are added during the production process of the roll, and these elements will form an alloy layer on the surface of the roll. This increases the difficulty of cutting the roll.

·Defects are difficult to avoid and the processing conditions are complex.

 Some rolls that need to be turned have defects such as sand inclusions and pores, and the processing conditions are complex, resulting in tool collapse, poor wear resistance, and poor impact resistance.

In response to the above difficult processing problems, Moresuperhard summarized the existing customer groups and cases about using CBN cutting tools to process brittle hard materials and difficult-to-cut materials (involving customers in Brazil, the United Arab Emirates, India, Pakistan, Arabia, etc.), and focused on CBN cutting tools.

 In the field of boron tool processing rolls, the following complete sets of product options are provided (roll grooves are diverse, and different tools are used for different roll grooves. For example, ordinary round grooves can be processed by choosing a standard CBN cutting tools, but for other irregular shapes, Moresuperhard supports customized non-standard tools) and solutions (contact us and we will provide specific processing suggestions for your actual processing).

Selection of turning tools for roll machining:

For high-hardness rolls, the current turning tool materials include CBN tools and PCD tools. CBN tools are cubic boron nitride tools, and PCD tools are diamond tools. Choose different super-hard tools for different materials.

CBN cutting tools for Roll

The main components of CBN tools are CBN particles (cubic boron nitride) and special ceramic and metal bonding agents. CBN cutting tools have high hardness at normal and high temperatures. A tool material that has less chemical reactivity with the material being cut. Mainly aimed at ferrous metal materials, such as high-nickel-chromium cast iron rolls, chilled cast iron rolls, nickel-hard cast iron rolls, high-speed steel rolls, high-boron steel rolls, etc., large margin cutting, even if there are serious sand inclusions/pores on the surface, there will be no any impact.

The hardness of CBN cutting tools is much higher than that of carbide cutting tools and ceramic cutting tools, and it also has good wear resistance and impact resistance. Through strict control and continuous optimization and improvement of CBN micro-powder size, binder, CBN content, etc., 

Moresuperhard has produced CBN cutting tools that can effectively solve the problems in the roll processing process, taking into account both wear resistance and impact resistance. With its longer life and higher processing efficiency, it stands out among many tool brands and is widely popular. It is capable of handling harsh working conditions such as high hardness, large depth of cut, and strong interruption, and can achieve efficient processing of rolls for customers in different countries.

PCD cutting tools for roll

PCD cutting tools are mainly aimed at carbide rolls/roll rings. The hardness of carbide rolls is too high and has exceeded the hardness range that CBN tools can withstand, so higher PCD tools can only be used for turning them.

In response to the above difficult processing problems, Moresuperhard summarized the existing customer groups and cases about using cubic boron nitride tools to process brittle hard materials and difficult-to-cut materials (involving customers in Brazil, the United Arab Emirates, India, Pakistan, Arabia, etc.), and focused on cubic nitride cutting tools.

For example, ordinary round grooves can be processed by choosing a standard CBN insert, but For other irregular shapes, Moresuperhard supports customized non-standard tools) and solutions (contact us and we will provide specific processing suggestions for your actual processing).
