Business introduction

We are constantly delivering new products to customers around the world with our unique, high-value-added technologies.

We are aware that Komatsu NTC's engineering is the best in the world.
We aim for innovative originality as a supplier of the world's leading total engineering, which we have built up through constant and friendly competition at the cutting edge of engineering with the automotive industry at its core.

True technology is the fruit of philosophy. Wisdom is the driving force of corporate development.

Based on the "sensibility of a leading supplier" driven by these two, we will continue to steadily move forward at the forefront of the global stage.

Main fields in which we operate

Battery Manufacturing Field

Automotive battery manufacturing equipment with higher quality and higher productivity is required for automotive batteries, which are in high demand and are subject to higher loads as a result of the shift to EVs.

Komatsu NTC's original on-board battery manufacturing equipment, such as tab forming machines, lid welding machines, can sealing welding machines, and press machines, have been highly evaluated by our customers, the manufacturers of on-board batteries,

In recent years, Komatsu NTC has taken the first step as a line builder in the automotive battery market by integrating high-speed conveyors and image inspection systems, and commercializing highly difficult stacking machines, winding machines, and module assembling machines.

Komatsu NTC, as a Japanese manufacturing company, aims to be a partner company that can help automakers and automotive battery manufacturers with any problems they may face.

Semiconductor Manufacturing Field

Capable of processing silicon ingots and other materials such as quartz and crystal, we have supplied numerous wafer manufacturing equipment to the semiconductor, solar cell, and LCD industries.

Our multi-wire saws ensure high rigidity and static accuracy, and minimize wafer waviness by utilizing tension control and thermal displacement control technologies that we have developed over many years.

In addition to reducing the burden on post-processing by achieving stable, high-precision processing, our technology for reducing material loss during processing and increasing wire speeds through the use of finer wire brings high productivity to our customers.

Automotive Industry

SMART-FTL
By incorporating the latest IoT technologies into our FTLs, or Flexible Transfer Lines, we help customers achieve labor savings and high productivity on the shop floor. Drawing on decades of expertise in machine tool design and manufacturing engineering, we combine dedicated machining equipment and transfer systems with Komtas, Komatsu NTC’s proprietary machining monitoring system, to provide customers with ideal production solutions.

Machining Centers
The shift toward electric vehicles is rapidly changing the types of workpieces processed and the level of machining accuracy required of machining centers. Komatsu NTC offers a lineup of machining centers based on machines renowned for their exceptional quality and durability, proven on the demanding production lines of automotive manufacturers.
The CX500, our latest horizontal 5-axis machining center, combines our accumulated manufacturing expertise with advanced IoT technologies to serve a wide range of applications, including electric vehicles, construction machinery, and aerospace.

Grinding Machines
Since launching the CGA cylindrical grinding machine in 1940, we have supplied a wide range of grinding machines to the automotive industry and various other sectors for over 80 years. We remain committed to delivering highly reliable grinding solutions tailored to customers’ production environments, with a focus on quality, productivity, and automation.

Crankshaft Processing Machines
Komatsu NTC offers a broad lineup of crankshaft milling machines, ranging from models for small crankshafts used in motorcycles, compact generators, and automobiles to machines for large crankshafts used in trucks, construction machinery, and marine engines. Their highly rigid design enables efficient rough machining of cast crankshafts.

Crankshaft and Camshaft Measuring Instruments
The GDBV-2 Series can measure both crankshafts and camshafts on a single machine and can accommodate multiple workpiece types through simple program changes.
The DD Series balancing machines measure the geometry of crankshaft forgings and calculate their dynamic centers of balance during rotation. The calculated center coordinates are transferred directly to a machining center, enabling optimal center-hole machining. Based on a concept fundamentally different from that of conventional balancing machines, the DD Series provides innovative solutions for crankshaft machining lines.
