DavyMarkham offers a diverse range of CNC machining services and capabilities which range from
mid size batch work, including components weighing a few tonne, to those one off bespoke
components of a maximum of 300 tonne.
The machining facility is broken into two very different areas.
In the light to medium machine shop there are a range of machines capable machining to
exacting tolerances on components up to 125 tonne:
Centre Lathes
Vertical Borers
Table Borers
Elgamill
Gantry Milling
The largest machine bay (5 Bay, pictured above) comprises of a machine
bed which covers half of the entire bay (34.5m x 14.7m). This
unique facility enables very large castings and fabrications to be
machined with minimal set-up time.
The huge bed plate is surrounded by CNC ram borers machining to exacting tolerances, all large work
pieces can therefore be machined with precision and are governed only by
the weight limits of the overhead cranes.
