SCBN TOOLS Super Hard CBN Tools Empower Roll Machining

In the rolling production process of the steel industry, rolls are core components determining the precision and quality of plates and profiles. Their high hardness (HRC50-65) and high toughness have long presented the machining process with the triple challenges of low cutting efficiency, rapid tool wear, and difficulty in controlling precision. SCBN TOOLS, a brand specializing in super hard material tools, uses cubic boron nitride (CBN) inserts as its core technology to provide efficient and precise solutions for roll machining, becoming a key support for steel companies to improve roll machining efficiency and reduce production costs.

SCBN TOOLS CBN inserts have a hardness second only to diamond, a thermal stability of up to 1300℃, and strong chemical inertness with ferrous metals. The solid CBN inserts enable “high-margin, high-efficiency cutting” of rolls. Taking chilled cast iron rolls as an example, their surface hardness is high and contains sand inclusions and pores, making them prone to chipping during machining. SCBN TOOLS CBN inserts feature a reinforced cutting edge design, significantly improving impact resistance and extending single-insert life to 20 times that of traditional carbide inserts. This not only reduces downtime for insert changes but also enables direct machining of surface finishes below Ra1.6, eliminating the process for subsequent grinding.

For interrupt cutting scenarios involving cast steel rolls, the CBN inserts utilize a special edge-strengthening treatment to effectively prevent chipping caused by impact. Addressing the high-temperature challenges of machining alloy forged steel rolls (cutting temperatures reaching 900℃), SCBN TOOLS CBN inserts, thanks to their excellent thermal stability, maintain stable hardness even at high temperatures. This eliminates the need for insert changes during the entire machining process of a single roll, increasing daily output per machine by 30% and completely resolving the pain point of traditional inserts’ high-temperature failure. This combination of “high efficiency + precision + low cost” has led to the widespread application of SCBN TOOLS products in high-speed steel rolls, high-hardness cast iron rolls, and other fields, making them the designated cutting tool supplier for many large steel companies.

In practical applications, SCBN TOOLS CBN inserts are not only compatible with various roll materials, but also help steel companies reduce the overall cost of roll processing by 35% by optimizing cutting parameters and providing full-process technical support, becoming a core tool for promoting the dual upgrade of roll processing efficiency and quality.
