Must-see for those struggling with Carvic couplings! [Includes special materials]

For those seeking processing of custom-made items and catalog items.

Ogjik has over 70 years of experience in manufacturing gears. We have received numerous inquiries regarding gears, such as "I want to reduce the noise of the spindle gear in machine tools..." and "I would like to have custom gears manufactured..." and have provided solutions to various challenges. Among these, we particularly encourage those who are struggling with curvic couplings to consult with Ogjik. If you are facing issues like "I can't find a manufacturer for special specifications of curvic couplings..." or "I want high-precision curvic couplings," this is a must-see. In fact, we have received many such inquiries. One of our features is that we can handle prototype production to mass production of around 1,000 units, which is often difficult for large gear manufacturers or trading companies that sell standard products. We consistently design and manufacture products with special specifications, such as 0.5-degree and 2.5-degree indexing, as well as improving the precision of off-the-shelf products. Our technical site, [Custom Gear Manufacturing.com], showcases numerous production achievements and technical proposal examples, so please take a look!
