What We Do
Milling
Our XYZ LPM machining center allows us to create custom components accurately and efficiently, whether for individual pieces or small to medium batches. Programming can be done directly on the machine or offline using our dedicated CAD CAM software. This capability enables us to precisely machine components based on our customers' CAD models.
Complementing our CNC capacity is the KRV3000 manual mill, which aids in producing unique pieces and tooling essential to our operations.
Turning
Our workshop boasts the capability to manufacture components using our Leadwell CNC lathe and Harrison Alpha 330plus machines. The CNC is perfect for batch production, aided by a bar puller. While the Alpha handles one-off parts with manual precision and small batches efficiently with its dedicated CAM software.
Subcon
Assembly
With our extensive experience, we offer both component manufacturing and assembly services. This allows our clients to focus on other project aspects, saving them time and resources. Trust us to handle your project needs efficiently.

Meet The Engineering Team
Mario Mclaughlin
Director/Owner
I went straight into Engineering as an apprentice Toolmaker after school for 5 years and manufacturing/Engineering at college.
I then went onto another role in production and development as a supervisor on manual and CNC machines. Working on pharmaceutical and defence projects.
Keeping a passion for engineering after many years in engineering I decided to set up on my own along with Michelle.
Hobbies - Petrol head at heart with a love for music and a love for engineering.
Michelle McLaughlin
Director/Owner
Starting out in child care, I soon realised that there was more out there.
After moving to a local engineering company I soon started to excel in purchasing. Then moving into an international packaging company purchasing engineering components from all over the world.
After many years in packaging I went to a company that manufacturing fire pumps, which gave me more experience in engineering.
I have since had experience within the core drilling business and safety industries. My natural progression was to work together with Mario at Mario James Precision Ltd.
Hobbies - Classic cars, looking the next bargain (you can't ever take the buyer out of me) and volunteering at a local bunny charity.
