Material processing line

This line is where sheet steel is cut, formed, and machined as necessary to make parts that are subsequently sent to the different manufacturing lines. A CO₂ laser machining center with a state-of-the-art 4.5-kW CO₂ laser head was installed in May, 2015, and is capable of handling up to ten sheets of steel as thick as 25 mm and as large as 3.0 × 1.5 mm in size during long-term automated operation. Also, each press brake is connected via a LAN to our integrated production system, which synchronizes production and optimizes delivery of more than 1,000 different parts to the manufacturing lines.

Large structure welding line (300kg – 2.5t)

This line is where we manufacture large steel structures known as deck frames, on which the cabin, engine, and a variety of hydraulic devices are mounted. It includes a large welding table, big enough for assembling structures as large as 5m x 3m, as well as two one-ton, triple-axis positioners and two dual-axis positioners. This line is used for the precision assembly of large, complex structures and permits downhand welding of all weld points. It is also equipped with automated guided vehicles (AGV), which minimize material handling losses, thereby achieving low-cost, high-productivity manufacturing.

Thick joint welding and horizontal boring line (20kg – 500kg)

This line is primarily used for the welding and machining of stress mechanism parts for construction equipment. Many of the products manufactured on this line are “critical safety parts.” Failure of these parts during operation of the equipment could cause personal injury, which means that they require especially high levels of welding quality and dimensional accuracy during machining. We also have in-house facilities for painting as well as magnetic particle, ultrasonic, and other types of non-destructive testing, and our quality control system provides the traceability necessary to meet all customer requirements for quality.

Bushing line

The bushing line is where a wide variety of bearings are produced for use in the arms, booms, buckets, and other movable parts of power shovels. These parts require a high level of precision and are produced under the strictest standards of our quality control system. Final inspection of completed parts is performed in an inspection facility with 24-hour temperature control, using precision inspection equipment per our quality assurance system based in statistical methods.

Stamping line

The stamping line is where metal sheets are formed into parts. Many of the parts made here are used in small functional components. We manufacture in close proximity to the customer to ensure optimal manufacturing and optimal supply.

Crimping and assembly line

This line is where hinges, door locks, and other small functional components are produced. We manufacture in close proximity to the customer to ensure optimal manufacturing and optimal supply.

Inspection equipment

Advanced inspection equipment is essential to the assurance of consistent levels of quality. At Kanehiro, we utilize a wide range of advanced inspection equipment, starting with our gantry-type 3D measurement device that is used for precision measurements in a temperature-controlled environment and including devices such as a portable 3D measurement device that can be used for highly accurate, on-site measurements of large steel structures, a profile measurement device, and a projector.

3D CAD

3D computer-assisted design is indispensable to the support of our manufacturing processes and is used for 3D design, stress analysis, and other forms of numerical analysis. Our development departments also are equipped with the devices necessary for fracture or durability testing. These are used in the development of the small functional components needed when we make proposals for mechanical parts with custom-designed mechanisms. These activities are how we stay abreast of our customers’ design needs from the very start of development, as we frontload in order to respond more accurately to customer needs.
