Flexible customization for
customer requirements

Our products can be customized based on standard models to meet each customer’s specific requirements. In many manufacturing environments, floor space is limited, and compact layouts are essential. We offer flexible solutions for material loading, chip removal, and overall workflow design to fit the movement and space constraints of each factory.

When higher productivity is required, we can propose automation options—such as gantry loaders—that allow multiple processes to be completed without manual changeover. These solutions help significantly improve overall efficiency.

With more than 20 years of experience in customization, we have developed a wide range of modular units and accumulated extensive know-how. By combining optional custom units with various transfer and handling options, we can fully tailor both the machine configuration and external equipment to meet your exact specifications.

Stable high-precision machining and high-rigidity

We perform precision hand scraping on lathe guideways to ensure smooth and accurate sliding motion. The design of our company logo is actually inspired by the unique patterns formed through the hand scraping process.

We provide both gang-type and turret-type tool configurations for NC lathes; our core expertise especially lies in high-precision gang-type systems. Turret mechanisms, while versatile for multi-station machining, inherently generate indexing and repeatability errors due to rotational positioning, clamping variation, and accumulated mechanical tolerances within the indexing structure.

In contrast, the gang-type layout fixes each tool rigidly on a common base aligned with the machine’s primary datum. Because the tool geometry, tool center height, and cutting edge position are all referenced to the same structural foundation as the workpiece, positional deviation is minimized to the micron level. This architecture eliminates indexing errors entirely and significantly reduces stack-up tolerances, enabling superior repeatability in finishing operations, tight-tolerance turning, and applications requiring stable tool engagement.

Through extensive development of fixed-base tooling systems, we have optimized structural rigidity, thermal stability, and geometric accuracy, allowing our gang-type lathes to deliver consistent high-precision performance in demanding production environments.

To achieve even higher machining accuracy, our machines are designed to minimize thermal effects. In addition to coolant circulation, we use linear scales to maintain positioning accuracy and a ball-screw cooling system to suppress thermal displacement at its source.

At the same time, our machines are engineered for exceptional rigidity. While many modern machines prioritize high-speed machining and tend to have lower rigidity than older models, we adopt a robust structure for the bed and slideways to withstand heavy cutting. The castings used in our machines are specially designed for high rigidity and are manufactured domestically. By incorporating these high-quality components, we deliver machines that customers can rely on with confidence.

Overwhelming durability and
easy maintenance

There are two types of slideway mechanisms used in CNC lathes: sliding guides and linear-motion (rolling) guides. Rolling guides are generally known for their smooth movement, but our advanced hand-scraping techniques compensate for the sliding guide’s weakness in extremely fine motion. As a result, our machines retain the advantages of sliding guides—stability, rigidity, and long-term durability.

The difference is most evident in service life. A rolling guide may begin to wear after around five years and require replacement of the entire guide unit, whereas a sliding guide can maintain accuracy for twenty years or more with periodic adjustment. Some of our customers have operated their machines for nearly forty years.

Maintenance also favors the sliding guide. If accuracy declines on a rolling guide, the guide unit must be removed and replaced, which requires disassembling the machine. With a sliding guide, accuracy can typically be restored by adjusting the gib. Even if the gib has worn after long service and adjustment is no longer sufficient, the gib alone can be replaced.
