Machining centers

In 1961, the turret type machining center "TAB-5" with automatic tool change was introduced, and since then, a series of highly versatile machining centers have been released. For mass production of powertrain parts in the automotive industry, we have contributed to 24-hour production by incorporating line-oriented machining centers that match every requirement into transfer machines and FMS lines. The DNA cultivated in the harsh work environment has been passed down to each machine in a continuous line.

Komatsu NTC technology

Komatsu NTC has delivered many fully automated lines for the production of pallet train parts in the automotive industry. Many of the ideas we have developed in the course of this experience have been put into shape and taken to a higher dimension in each elemental technology.

Durable and quality stable structure

Structure and durability to maintain stable quality and precision in 24-hour operation

Automation line support

Structure and control to minimize human movement, such as automatic jig change, automatic tool change, etc.

User-friendly

User-friendly equipment layout, size, and operability to minimize non-machining time
