Services
Machining, project management, assembly and repair
From one shop and one quality system, a large part can go from drawing to finished, assembled unit without changing supplier.
Engineering project management
Turnkey delivery of heavy engineered parts: fabrication, machining, 3D scanning, assembly and inspection, managed by one team from drawing to dispatch.
Read more →Fitting and assembly
Bench fitting and assembly of machined parts, from sub-assemblies to complete units, checked as one before they leave the shop.
Read more →Reverse engineering, repair and refurbishment
Legacy parts reverse engineered, worn parts re-machined or rebuilt, so plant goes back into service without waiting for a new casting.

Process 01
Large CNC horizontal boring and milling
Boring, milling, drilling and facing on large castings and fabrications in a single setting, cutting handling and keeping features true to one another.
- Doosan DB-130CX, full 5-axis; X 3,000 · Y 2,000 · Z 1,600 mm
- Union BFT130/7; X 2,785 · Y 2,400 · Z 2,345 mm
- Cogsdill facing head; 40-station tool changer
Process 02
CNC vertical boring and turning
Large diameter rings, flanges, housings and discs turned on vertical borers, where heavy parts sit stable on the table.
- 6 ft CNC vertical borer; Ø2,134 mm × 1,120 mm high
- Three 4 ft CNC vertical lathes (two standard, one S type with extra height); Ø1,829 mm, up to 1,650 mm high
Process 03
Large CNC milling
Vertical machining centres for plates, blocks and medium components that need accurate faces, pockets and drilled patterns.
- AWEA double-column VMC; X 2,000 · Y 1,200 · Z 760 mm
- Hurco VMX64Ti XP; X 1,625 · Y 864 · Z 762 mm
Process 04
Manual machining
Conventional boring for work that suits a skilled manual setup: one-offs, deep bores and awkward parts.

- Quick set-ups with no programming lead time
Process 05
Inspection
FARO portable arm inspection on and off the machine, with full dimensional reports available.
- FARO portable 6-axis measuring arm
- Checks on the machine, mid-job and at final inspection
- Full dimensional reports on request

Lifting capacity
Lifting capacity
Heavy parts move from lorry to machine without waiting for outside lifting.
Parts up to 10 tonnes are lifted, turned over and set on our machines by a 10 tonne and a 5 tonne overhead crane covering the shop floor. Heavy castings, fabrications and assemblies are handled in-house from arrival to dispatch.
Outside, two LPG forklift trucks unload deliveries and load finished work for collection, so incoming material moves straight from the lorry into the shop.
