[Processing Example] Groove Machining of 55HRC High Hardness Material (Intermittent Cutting)
Axial rake angle with low resistance design! A case that achieves high efficiency and long lifespan.
We would like to introduce a case where our "Shoulder 6" achieved high efficiency and long tool life through groove machining (intermittent cutting) of high hardness material with a hardness of 55 HRC. The customer's challenges included poor efficiency with the current tool at a low feed rate of Vf=60, the need for tool replacement after two passes leading to short tool life, and chipping occurring due to intermittent machining of the hole sections. In response, we realized improved machining efficiency and extended insert life with the "Shoulder 6 EXSIX type." We achieved more than three times the machining efficiency of the current products even for groove machining of high hardness materials. [Case Overview (Partial)] ■ Workpiece: Test piece (intermittent machining) ■ Material: Hardened steel (HRC55) ■ Challenges - Poor efficiency with the current tool at a low feed rate of Vf=60 - Tool replacement after two passes leading to short tool life - Chipping occurring due to intermittent machining of the hole sections *For more details, please refer to the related links or feel free to contact us.

Company information
Since our founding in 1938, we have recognized the potential of cemented carbide in industry and have independently pioneered innovations in cemented carbide tools and the evolution of processing. Based on the powder metallurgy technology cultivated in cemented carbide manufacturing, we have successively introduced innovative technologies to the market, including the world's first practical application of conventional cermet chips, the development of ball end mills and drills with spiral cutting edges, and end mills with twisted cutting edges. In recent years, we have created highly original new technologies in various fields, such as diamond and cemented carbide integrated sintered products, cemented carbide for irregular gear forming molds, and tool materials made from rare metal-reduced alloys, which we sell worldwide. In addition to developing materials and products, we consistently conduct in-house production from the preparation of raw powders, ensuring stable high-quality products, which we believe has earned us the trust of our customers. Today, there are very few products in the world that do not undergo machining processes such as cutting or plastic processing. Even in the realm of advanced science, the advancement of processing technology is essential for practical application and industrialization. In this era of global competition, we will challenge new fields without being bound by convention, adhering to the philosophy that "management is creation" and "richly creative technology development" to contribute to the world.
