COUPLINGS..

Modified couplings prove their

worth in diamond polishing

When a UK diamond toolmaking machine manufacturer needed a custom coupling

for use on its line of new extreme material finishing machines, it turned to Huco for
a precision solution. Huco was able to meet the requirements by modifying a
membrane-type coupling with special bore sizes and keyways, and ship it to the
OEM cost-effectively in the relatively small quantities required.

equipment to the polycrystalline
diamond industry and to the single

industry. With customers across the
globe, the company exports over
90% of its machines, meeting the
needs of users who need to precision
polish, grind and shape some of the
world’s hardest and most extreme
materials.
One of the company’s key
product ranges is its planetary scaife
benches, used to polish facets on
single crystal diamond tools or for
gem diamond polishing. These benches combine flat. In addition, the motion results in a constantly
