At JR Gilbert Engineering, we specialise in manufacturing high-precision bespoke components for the machine-building industry. With over 40 years of experience, we understand the unique challenges of bespoke machine manufacturing, where large orders often consist of a wide variety of different components, each requiring exceptional accuracy, consistency, and on-time delivery to prevent delays in the build process.
As a trusted machined parts manufacturer, we provide high-quality CNC milling and CNC turning services for automation, robotics, production equipment, and heavy machinery. Operating from our modern 40,000 sq. ft. facility in Oakdale, Blackwood, we offer a comprehensive in-house machining service, reducing lead times and ensuring complete quality control. Whether you need one-off prototypes, small-batch production, or large-scale manufacturing, we have the expertise and capacity to support even the most complex machine-building projects.

Why Choose JR Gilbert Engineering For Bespoke Machine Parts?
On-Time Delivery to Keep Machine Builds on Schedule
In the bespoke machine-building industry, a delayed part can hold up an entire project. We recognise the importance of on-time delivery and operate a shift-based production system to maximise efficiency and meet tight deadlines. Our experience handling large, multi-component orders means we can coordinate production schedules to ensure all parts arrive when needed, keeping your machine build on track.
A One-Stop Supplier For All Machined & Fabricated Parts
Bespoke machine building requires a diverse range of components, from large fabrications to small precision-machined parts, often made from different materials. Managing multiple suppliers can be time-consuming and complex. JR Gilbert Engineering simplifies this by offering a full range of services in-house, so you can rely on one trusted supplier to handle all your component needs, including:
Large fabrications – Custom frames, brackets, and welded assemblies.Precision CNC parts – Machined housings, fixtures, and mechanical components.
Turned components – Shafts, bushings, rollers, and precision fittings.
Surface-ground components – Precision-ground bed plates and mounting surfaces.

Machining A Wide Range Of Materials
Bespoke machinery manufacturers often require parts made from a variety of materials, each chosen for its unique properties. We have extensive experience working with:
Mild steel & stainless steel – Ideal for machine frames, support structures, and high-strength components.Aluminium – Lightweight and corrosion-resistant, commonly used for machine enclosures and precision parts.
Plastics (PEEK, Acetal, PTFE, Nylon) – Essential for electrical insulation, wear-resistant components, and low-friction applications.
Hardened & heat-treated alloys – Used for high-wear components such as gears, shafts, and bearings.
Industrial Spare Parts & Large Order Management
We also support businesses as industrial spare parts suppliers, providing high-precision replacements for worn or obsolete machine components. Our ability to manufacture large, mixed-component orders ensures that every part is delivered on time and to exact specifications, whether for new machine builds or equipment maintenance.
Complete Finishing Services – Ready-to-Use Components
In addition to manufacturing, we streamline the supply chain by offering in-house finishing services, ensuring that all parts arrive fully finished and ready for assembly. Our finishing capabilities include:
Anodising – Corrosion-resistant finishes for aluminium parts.Hardening & heat treatment – Strengthening high-wear components.
Powder coating & wet painting – Protective coatings for machine enclosures and fabricated parts.
Zinc plating & galvanising – Corrosion resistance for steel components.
ISO 9001-Certified Quality & Reliability
As an ISO 9001-certified company, quality is at the core of everything we do. Whether producing industrial spare parts, large-scale machined assemblies, or high-precision turned components, we ensure that every component meets the highest industry standards for accuracy, durability, and performance.
