Union Tool is a company that manufactures and sells industrial cutting tools. Its primary product, ultra-hard drills for printed circuit boards (hereinafter referred to as PCB drills), holds the largest market share both domestically and internationally.
Since the inception of PCB drill manufacturing and sales in Japan in 1963, the company has established itself as a leader in the industry, leveraging its technological expertise and quality advantages. In 1998, it was listed on the first section of the Tokyo Stock Exchange.
Printed circuit board (PCB) drills are essential tools in the manufacturing process of printed circuit boards used in electronic products, such as computers and mobile phones.
To accommodate the processing of multifunctional and miniaturized electronic products, PCB drills also need to develop finer drills. Union Tool Group can now mass-produce drills as thin as hair, and such demands will continue to increase.
The high quality produced by its ultra-precision machinery has resulted in a larger market share.
The drills produced by Union Tools are manufactured using independently developed, specialized equipment. Both the manufacturing and inspection processes, as well as the packaging, are conducted with dedicated machinery to ensure a high standard of quality in production.
In response to the significant increase in demand for minimal diameter processing, our company has established a clear direction from an early stage. We have developed image processing inspection devices and specialized re-sharpening machines for minimal diameter drills to ensure a swift response to market changes.
The independent development of specialized machines reduces equipment investment, resulting in lower costs. This approach allows our company to secure a larger market share both domestically and internationally.
Union Tools offers a comprehensive support system that includes peripheral measurement, grinding, and ring mounting equipment, enabling the more effective and rational use of cutting tools.
The cutting tool is made from cemented carbide, with tungsten carbide as its primary component.This material is extremely hard, yet it is also quite brittle. Therefore, it must always be handled with great care. Even a slight contact between the drill bits can cause he cutting edge to break.
Using a drill bit with a nick can result in a rough inner wall of the board, accompanied by resin sludge and burrs. To ensure the quality, precision, and longevity of your cutting tools, be sure to use the non-contact instruments produced by Union Tools.
The UNIMAX ultra-hard vertical milling cutter series has a rich product line, offering products ranging from a diameter of φ0.06mm to φ20mm for different purposes.
Made of cemented carbide, carbide vertical milling cutters are affirmed by customers in terms of performance, quality, and product line, especially for specifications requiring higher precision below φ12mm.
The UNIMAX series uses independently developed production equipment and measuring instruments to ensure good dimensional accuracy of the products.
By independently developing grinding programs, unique blade shapes are designed, and coatings developed for various processing materials enable the processing of cemented carbides that could not be machined directly before.
Linear guides are installed on the load body, ensuring smooth motion with high precision, exceptional rigidity, and extended durability.
It is primarily utilized in automated machinery and semiconductor manufacturing equipment. To prevent wear caused by friction as the load body slides back and forth, our company has developed high-performance bearings utilizing proprietary technology.
PCB drill production and research and development (R&D) utilize stable grinding processes to manufacture linear guides that exhibit high rigidity and precision. It was the first to be listed in Japan and holds a significant market share in the country.
Linear guides featuring nearly mirror-like sliding surfaces (SF grade), which are not produced by other companies, are extensively utilized in mechanical structures that demand higher precision, such as optical measuring instruments and medical equipment.
As a high-precision measuring instrument essential for stringent quality control of PCB drills, the company has successfully developed and commenced production.
The diameter of the company's PCB drills ranges from 0.1 to 0.3 mm.
The allowable tolerance is limited to just a few micrometers (1 micrometer = 1/1000 mm), and shipments will not be permitted without this stringent inspection.
Turning tools produced through grinding technology have attained consistent high-precision processing, whether they are gear shaping cutters or hobs.
Our company specializes in the manufacturing and processing of products such as worm gears, splines, lead screws, ball screws, and various types of screws. In addition to traditional gear-shaping cutters and hobs, we also manufacture and sell press tools, including screws. Tools produced using independently developed precision grinding equipment, along with subsequent material modifications or surface treatments, have resulted in extended tool life.
Make full use of the experience in transforming product manufacturing for unique tool design, enabling the production of items with high precision and a brilliant finish. Equipped with turning equipment, trial turning processes can be conducted.
