Supports all types of precision machining! We process various materials!
At Riso Precision Co., Ltd., our high-precision and high-detail processing goes beyond merely pursuing accuracy; we accommodate all types of fine processing. We handle large and long-length machining for various industries, including aircraft parts, coating equipment, resin forming nozzles, and LCD-related devices. In addition, for difficult-to-cut materials and complex shapes, we can process any material using machining, lathes, and grinding. We work with a variety of materials such as Hastelloy, Inconel, Invar, molybdenum, MMC, CFRP, pure carbon, SiC, and titanium, so please consult us if you have any issues. Furthermore, in lathe processing, we are committed to achieving extremely small outer and inner diameters, and we can turn large workpieces up to 750 mm in diameter. We are open to discussing larger diameters as well. We excel in processing complex shapes and difficult-to-cut materials, turning various forms. For more details, please contact us or refer to our catalog.

Detailed information
-
High-precision machining Material: CFRP, machining requires a high level of hole tolerance, roundness, and surface roughness. Surface roughness Ra0.5μm (polished) for CFRP.
-
Difficult shape machining Material: S45C, aircraft fixtures, machined products containing many three-dimensional elements
-
Difficult-to-machine materials Material: SiC (silicon carbide) is a hard and brittle material. The fixture for this product is made of carbon and machined with diamond tools. Silicon carbide is the third hardest material on Earth, and even slight cracks during processing are unacceptable.

Company information
Humans have devised something to live. They tried breaking a round stone by the roadside. Then, a sharp piece emerged as a fragment. It was just right for cutting, so they sharpened that fragment. It turned out to have quite good cutting ability. Even things that seemed good quickly became boring, new tools were created, and new uses were born. Through this repetition, technology has evolved and continues into the future. For us in the manufacturing industry, "creating" is a means of survival. We strive to refine ourselves, seek a better way to live, and contribute to further evolution. There are processes that cannot be done even with equipment and programs; they can only be created through human effort. Contributing to society with the high productivity that arises from this is our company's mission.
