Leaders in the supply of machines for the diamond tooling industry
Coborn's entry into the diamond grinding market has been an evolutionary process, based on our fundamental skills in balancing and spindle design. Coborn has a unique, global position supplying specialised, individually built, high-precision equipment to the polycrystalline diamond industry, single crystal diamond and the gemstone industries, with over 90% of machines being exported throughout the world
Coborn has a unique, global position supplying specialised, individually built, high-precision equipment to the polycrystalline diamond industry and the gemstone and natural diamond tooling industries, with over 80% of machines being exported throughout the world.
In addition to the RG machines for the PCD tooling market the other products include Planetary Grinding (PG) machines for natural diamond and single crystal diamonds, scaif spindles, high frequency milling and grinding spindles, dynamic balancing machines, lapping, polishing and edge honing machines.
For nearly 70 years, Coborn Engineering has been actively involved in many aspects of machine tool design and manufacture. Established in 1941, the company initially manufactured high precision spindle and balancing machines. In 1962 this developed into manufacturing Scaif Spindles and Planetary Grinding (PG) machines for the gem and single crystal diamond industry.
Then, with the introduction of polycrystalline diamonds in 1978, Coborn designed and manufactured the Reciprocating Grinding (RG) machines. In 2002 Coborn also introduced a laser cutting machine for PCD.
Coborn continually strive to improve their products and service. Coborn works closely with their customers – this contributes greatly to product development and performance enhancement. Coborn uses the latest machine tool technology, combining in-house hardware and software design with the best equipment available from around the world.
As a Company with an impressive history (if we do say so ourselves), we are proud of our roots but above all, proud of the progressive evolution to the business we are today. Life for us began as a humble manufacturing company with an extraordinary level of skill within our employees, allowing us to design and develop technology and techniques which challenged the status quo of precision engineering and become globally recognised as providers of precision engineering excellence.
Fast forward more than 70 years and we are still doing the same! With our strategy to progress the Company from Manufacturing to Engineering, and ultimately a Solution Provider Coborn are re-focussing our perspective on how we approach all aspects of our business with supporting our customers and fulfilling their requirements at the forefront of everything we do.
With our beginnings as a family-run organisation, we continue to recognise our people as our biggest and most valued asset. Our company strives to be true to the values which Coborn was built on and are still as relevant now, as ever before.

Coborn has a history of producing engineered solutions for industry starting with the Gyro Balancer designed by Sam Innocent which was stipulated for use in the aeronautic industry until c1960. The business evolved into making machines for the diamond industry, Coborn has been in the forefront of providing new technology and new processes for this global business since the 1960’s.
The use of diamond tools has grown steadily since the introduction of PCD in 1980 but with the use of aluminium in the automotive and smart phone market the growth has increased significantly, especially in China.
The latest development in the industry is the introduction of synthetic diamonds, which is opening up many new potential applications for the use of diamonds.
