CME's grinding cup is specially designed for use in CME grinding machines. The Super Diaroc HD grinding cup has been developed using premium grade materials, innovative design, longtime global experience, and the latest manufacturing techniques to ensure optimized grinding results and long service life.

Conventional grinding cups are limited as they are unable to maintain their profile insert over its life and eventually flattens the face of the grinding cup. As a result, the carbide profile flattens and protrusion of the carbide insert is reduced which affects the bit's ability to penetrate the rock effectively. This means diminished productivity and increased costs during drilling because the re-sharpened carbide inserts are unable to crush rock efficiently.

Two main factors contribute to good drilling performance and minimized costs associated with maintenance of all drilling equipment, including the bit. The proper button protrusion and the proper button profile of each carbide are the key elements to maintaining the bit's capacity to crush rock effectively. CME's patented technology restores button protrusion over the face and gauge of the bit to "new-like" condition. The net effect during drilling is constant, maximized penetration rate and increased bit life by as much as 60%.

CME offers a wide variety of blasting and mining accessories, including blasting wire, blast mats, grinding wheels and a complete line of hoses.
