About Us

Creativity and Advancement, Addressing our Customer's Need

Achieve thorough quality control and rationality, and respond to customer's various orders under a complete system.

Our business is formed of two pillars: metal cutting blade manufacturing division and large diameter circular saw blade manufacturing division (saw blade). The metal shearing blade is manufactured and regenerated at the Osaka plant and the saw blade is manufactured at the Nara plant.
In addition, in Soka City, we have opened the Tokyo plant as a processing plant dedicated to regrinding and wire cutting in the East Japan area.

  • Osaka Factory
  • Nara Factory
  • Tokyo factory

Among metal cutting blades, there are shear blades (straight blades), rotary knives (round blades), special blades for hot cutting, and various cutters for recycling and industrial waste processing machines. Saw blades are hot saws and cold saws, and are φ1000 to 2500 mm circular saw blades used in blast furnace and electric furnace rolling processes.

We meet the customer's work content, select the best material, consider the shape and heat treatment in-house, and suggest the best possible product to the customer. To that end, machining, wire cutting, CAD and CAM are regularly updated, and we are constantly working to build products with the latest equipment. In addition, our staff has always made an effort of "ingenuity" with five goals of "improvement of ability", "improvement of technology", "improvement of accuracy", "improvement of productivity" and "reduction of cost". Products produced and delivered in this way are highly praised by customers in Japan and around the world. And even after the product is delivered, we value the relationship with our customers and constantly exchange information to help improve product quality.

Manufacturing Process

  • Consultation

    •  Consultation

      We first consult our clients to decide the appropriate course and materials for the target project. Materials selection is based on customer needs and intended use of the tool (post-production). After an initial consultation our sales and manufacturing divisions develop a plan best suited for the customer.

  • Determine Technical Specifications

    •  Determine Technical Specifications

      Resolve the steel type, grade, and hardness to be used for the project. Our sales representatives and technicians are always available to visit location for a more detailed consultation.

  • Material Selection

    • Material Selection

      Selected materials are cut and delivered to our mills for processing.

      We designate a reliable steel composition for the manufacturing of all blades. Including a various assortment of special select steels we have a wide variety of steels in stock.

      The material is specially forged when there is no appropriately sized material in stock. We employ this forging method when crafting blades for larger tools.

  • Shaping

    • Shaping

      Blades are molded, shaped and cut to measurements and order specifications.

      During this step all materials are checked for warping, bending, and other irregularities.

      All blades are shaped from original materials using the most recent in machining and NC Processing.

  • Heat Treatment

    •  Heat Treatment

      Heat treatment is the most crucial step in the process of turning a mass of steel into an edged tool.
      We employ multiple furnaces for heat treatment depending on the size, and hardness specifications.

  • Grinding

    • Grinding

      In polishing, the final process of processing, products are "finished".
      The removal of distortion with a hammer and the curved surface finishing with sandpaper are also achieved by our superior polisher's excellent skill.

  • Inspection

    • Inspection

      A highly skilled metals inspector inspects every blade.
