A High-Quality CNC Milling Service
With over 40 years of experience, we specialise in high-precision CNC milling. Contact JR Gilbert Engineering today to get your project started.
What Is CNC Milling?
CNC milling is a precision machining process where computer-controlled machines remove material from a workpiece to create complex and accurate components. Unlike other CNC processes, milling involves a rotating cutting tool that moves along multiple axes to shape the workpiece. This method allows the creation of intricate parts with tight tolerances and complex geometries.
CNC milling is especially effective for producing components with flat surfaces, slots, holes, and even intricate 3D contours. It is widely used across industries such as aerospace, automotive, medical, and automation, as it can handle a variety of materials, including mild steel, stainless steel, aluminium, brass, and plastics as well as many others.

Benefits Of CNC Milling
Precision And Accuracy
CNC milling delivers exceptional precision and accuracy, enabling the production of components with tight tolerances. This makes it ideal for applications where even the smallest deviation can impact performance, such as in the aerospace, medical, and automotive industries.
Consistency And Repeatability
Once programmed, CNC milling machines can produce identical parts repeatedly with no loss of quality, whilst also preventing human error in altering the quality between parts. This ensures consistency across production runs, whether you're manufacturing a single prototype or thousands of components.
Versatility
CNC milling is capable of handling a wide variety of materials, including metals like steel, stainless steel, aluminium, and brass, as well as plastics and composites. This versatility allows manufacturers to cater to different industries and customise parts to meet unique requirements.
Complex Geometries
Thanks to advanced CNC milling machines and the power of our CAD/CAM programming software, intricate and complex designs can be machined with ease. Features like internal cavities, sweeping contours, and undercuts are achievable without the need for multiple setups or additional tooling.
Integration With CAD/CAM
CNC milling can be programmed directly on the CNC machine, however, this can lead to a lot of manufacturing time lost when the machine is being programmed before a part can be made. Our software, which integrates with CAD/CAM software and CNC machines, enables precise control over every aspect of the machining process and allows parts to be programmed offline (away from the CNC machine), this allows components to be programmed on a sperate computer ahead of time.
