About GCH Machinery


“We are open-minded and creative. Our customers believe in us 100%.
We have accomplished a great thing.”

— Dan Geddes, President, GCH Machinery

GCH Machinery has both the experience and know-how to take your older grinding machinery (centerless grinders, surface grinders, double disc grindersID grinders, OD/cylindrical grinders, microcentric grinders) and turn it into a world-class automatic grinding machine production center. We’ve been working with grinders and other machine tools for more than 50 years.


GCH Machinery’s roots go back to 1960, when Grinders Clearinghouse (GCH) was founded in Detroit, Michigan. Grinders Clearinghouse focused on the purchase and sale of grinding machines, eventually branching out into other machine tools. While the company originally targeted the U.S. market, GCH soon began to receive inquiries from companies located outside the U.S. and from foreign affiliates of current U.S. customers. The company became known as “the place to go for grinders.” GCH grew rapidly, moving to larger and larger facilities, increasing headcount, and establishing itself as the leader in the remanufactured grinding machine market worldwide. As the customer base grew, GCH would go on to set up complementary sister companies that would offer spare parts and components, service, control retrofits, new equipment, asset appraisals and liquidation services. Over time, GCH Machinery’s focus migrated toward the design, engineering and build of turnkey grinding solutions, while Grinders Clearinghouse remains the largest stocking dealer of pre-owned precision and tool room grinders in the world.


GCH Machinery works with customers all over the world and has created many long term, profitable partnerships. Our employees come from diverse manufacturing companies, with a focus on grinding machine operations. As a client of GCH Machinery, you’ll partner with grinding machinery experts who have more than 150 years of combined experience in grinding machine rebuilding and remanufacturing.  From design specialists to electrical engineers and beyond, our team will handle all aspects of your job, from application assist to final install.  Known for our innovation and passion, our team will take your grinding solutions concept and turn it into reality. We’d be happy to speak to you about our machine innovations, including our patented two-axis CNC dresser, our state-of-the-art servo infeed system and our servo drive transmission.


GCH Machinery is housed in a 40,000-sq.-ft manufacturing facility in Warren, Michigan (suburban Detroit). The facility houses a state-of-the-art metrology laboratory equipped with over $1 million dollars of Carl Zeiss testing equipment. Our investment in an unrivaled metrology laboratory gives a clear indication of our unwavering quality standards.
