DavyMarkham - Services - Machining
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.


Key statistics for machining facilities:
Machine typeNumber of machinesCapacity (max)
Plano milling35.1m x 4.5m x 13.2m
Gantry Mill14.8m x 2.2m x 14.0m
Ram Borers85.0 x 1.5m x 14.0m
Horizontal Borers72.0m x 1.0m x 6.0m
Vertical Borers612.9m swing x 3.9m height
Large Centre Lathes62.0m dia. x 14m long

To facilitate the machining of such large components DavyMarkham is capable of single or beam linked crane lifts.
