The Precision Technologies Group
was prominent at this year’s EMO
Hannover with Holroyd Precision,
PTG Heavy Industries, Precision
components and PTG Customer care
in attendance on the PTG stand.

Holroyd’s new Zenith grinding
machine was on show. It uses three
grinding technologies: aluminium
oxide, diamond hard plated CBN
and vitrified CBN. The machine will
have the capability to grind some of
the largest rotors in the industry at
420mm and offers the flexibility to
use tooling from the company’s
existing range of grinding machines
and those of its competitors.
