“Nothing is impossible at Ohori Grinding Company” This philosophy bought the company to become an industry leader in the industrial grinding field. Ohori can guaranty ground materials to a precision of one micrometer. Ohori holds itself to the highest standards in the industry by testing all of its custom ordered products at its in house laboratory, where every product is tested innumerable ways before being sent out to customers. All innovations in grinding technology are also subjected to the most rigorous tests in order to ensure that they are on the cutting edge of applied technology and that they are constantly innovating new approaches to the field to keep themselves ultra-competitive in the fields of medical and aerospace manufacturing.
Ohori at One Micrometer – A New Milestone.
Ohori Grinding is located in the town of Kakamigahara, known as the heart for Japanese aircraft industry. Ohori factory houses fifty precision machines that can grind cylinders, interior surfaces, and machine parts. One thing that all visitors to the factory notice is how silent the factory is, despite of all of the high-tech grinding. This quiet grinding factory nestled in the Japanese countryside may go unnoticed, but its craftsmanship is highly sought out by a diverse number of industries worldwide.
In 2013, Ohori received a call from European F1 racing world, inquired whether they could grind a very fine elongated object. “I was literally trembling when I looked at the mechanical drawing,” said Ohori’s top engineer. He covered his mouth in embarrassment saying, “I voiced my doubts to the CEO, recommending not to take the project.”
Mr. Ohori, CEO of Ohori Grinding, explains, “I was aware of the challenges but I wanted to give it a try.” Mr. Ohori wanted to work with the power of possible. The team looked into the impossible and worked on the project for over a year and a half. They faced the challenge of having to grind interior cylindrical surfaces and complex three dimensional designs, without sacrificing highly specialized functionality. They were challenged to grind a surface down to a functional space of one micrometer. And they were able to accomplish more than what they were set out to do, and wound up doing what was thought to be impossible.
Breaking the Boundaries of High Precision Grinding
Some metals such as aluminum, stainless steel and inconel have long been considered unsuitable for high precision grinding because of their particular properties. But these metals have an advantage of being both light weight and sturdy. Ohori made simple changes to their bearings settings to be able to grind process light weight metals such as aluminum. And through bracing techniques, Ohori was able to grind an iconel tube with a diameter of 570 mm and a length of 2000mm with high precision. They challenge the impossible and broaden the potential within the grinding industry. “We will take on any complex designs and find an appropriate grinding solution for all”.
Carbon fiber reinforced plastic (CFRP) is a particularly interesting material in that it is many times stronger than steel and much lighter than aluminum, making it useful for a wide number of industrial applications, from medical equipment, X-ray technology to aerospace engineering. Because of its hardness and vulnerability, it has been labeled as an unsuitable material for grinding. But at Ohori, again, nothing is impossible. Ohori’s research team wrestled with the idea of working with CFRP.
Grinding Without Borders: Moving Beyond Traditional Partner Industries
Exciting partnerships are springing up around Ohori. In 2008, Ohori was honored to be invited to participate in an Aerospace Industrial Research Summit sponsored by the local Gifu county government. In 2010, the company was named a JISQ9100 licensed factory for the aerospace defense industry. In 2011, Ohori was named a certified medical manufacturing facility by the most recognized Japanese certification granting authority.
Ohori has devoted a significant portion of their second facility to a distinctive thermostatic laboratory. Ohori is also making innovations with customizable large cylindrical objects that can be as large as 600 mm in diameter by 900 mm long. The company receives many exciting inquiries that many other companies would turn down because of the complexity and the cost. “ It doesn’t matter how big or small the inquiry is. Because we are not looking at maximizing our profits, we strive to serve the needs of our customers and humanity” Mr. Ohori passionately continues, “we do not see customers as consumers, we see them as partners.” Mr. Ohori’s attitude is refreshing in today’s profit driven world. “At the end of the day, I personally live by the power of possible. Partnerships we build with our customers are long lasting and based on mutual trust.”
