On-Site Milling

On-Site & In-Situ Milling

Nicol & Andrew’s versatile portable milling equipment includes key mills, three-axis milling machines and custom made window frame mills for fast and accurate machining of large areas.

How You Benefit By In-Situ Milling

  • Fast response
  • Downtime reduced (to as little as 24 hours)
  • Always available, 24/7 service
  • High-quality finish
  • Faster and cleaner than grinding
  • Flat, level, square faces easily achievable.

Will Our Machines Mount On Your Equipment?

Key mills clamp directly onto the shaft. Our other machines can be bolted, clamped or welded into position.

Our Milling Machine Capabilities

Typical machining operations include:

  • Machining of tube sheet division grooves
  • Levelling pump and motor base pads
  • Re-cutting previously damaged keyways on shafts
  • Orbital milling of large diameter faces

On-Site Milling Capacity

Our keyway mills will mount on shafts from 13mm–600mm diameter.

Most on-site milling work falls within our scope of works. The modular construction of our portable milling machines, the power of their hydraulic drives and our capacity to adapt them allow us to cope with most situations.

We cater for carbon steel, stainless steels and most alloys.

Typical Applications

Machining structural steelwork in situ, milling “T” slots in bedplates, restoring flatness on motor test beds, machining jib rails on dockside ship to shore cranes.

Our on-site milling services are used extensively by the power industry, marine, oil and gas, manufacturing and water utilities.
