Workshop Services



There are an infinite number of situations which might require precision turning. Most commonly, our turning services are required for the reclamation or re-manufacture of bespoke items.

Line Boring

Our purpose built workshop facility in Milford Haven allows us to accommodate very large/heavy components. The 10,000 sq ft of space also allows us to operate and maintain some state of the art line boring equipment.


The advantage of having a large, purpose built workshop facility at our disposal is the ability it gives us to install and maintain the best machinery for the job. We have five main workshop milling machines.


Precision grinding requires a controlled workshop environment, the right tools and highly skilled machinists. We offer a range of grinding services and operate and maintain three different grinding machines.

CNC Manufacture

We have two Computer Numerically Controlled (CNC) crafting machines here at M&A Engineering.  These innovative manufacturing centres greatly speed up the process of batch or production machining.


We operate two precision drilling machines, which allows us to complete all drilling tasks with the greatest level of efficiency, accuracy and control.


We have the slotting equipment to undertake most internal keyway requirements.

The details of our slotting equipment can be found by clicking More Information.


Our bandsaw can handle metals up to Ø355mm (or Ø14”).

On Site Services



There are circumstances when it’s either inappropriate or impossible to solve an engineering problem in the controlled environment of a workshop. For these situations we have a range of on-site machining and engineering services and equipment.

Line Boring

Sometimes the situation doesn't allow for a job to be carried out in the controlled environment of a workshop. For these situations we have a range of on-site line boring equipment and teams of highly trained mobile technicians.


There are many situations when it’s either impossible or impractical to extract a component for milling in the workshop. For these situations we have a range of onsite milling solutions.

Flange Facing

In order to provide a hassle free solution we have a range of mobile flange facing machines which can be operated on-site. When these machines are operated by one of our highly trained machinists the results are equal to those you’d expect in a workshop environment. Doing it this way saves you time, money and inconvenience.

Hydraulic Bolt Tensioning and Torquing

Our experience has shown us that hydraulic bolt tensioning and torquing is one of the most common requirements in all the major industry sectors. To help meet this demand we have developed a comprehensive, one-stop solution to pressurised joint integrity.

Skilled Engineer Supply

M&A Engineering offer a skilled engineers supply service of on-site machining (line boring, milling, turning/facing) and hydraulic bolting engineers who will travel worldwide for whatever your requirements may be.
