What is a CNC Milling Service?
A CNC milling service uses computer-controlled milling machines to remove material from a workpiece using a rotating cutting tool, producing flat surfaces, pockets, slots, bores and complex contoured profiles. Unlike our CNC turning services — where the workpiece rotates — milling holds the component stationary (or repositions it between operations) while the cutting tool itself rotates and moves across the surface in multiple axes.
Our CNC milling service at Elmax Engineering Ltd uses modern vertical and horizontal milling machine CNC equipment to produce components from a wide range of metals and plastics. Whether you need a single prototype or a full production batch, our milling capability covers everything from simple flat-faced brackets to complex multi-feature housings machined in a single setup.
A milling machine CNC centre follows a digital program — generated from your CAD drawing — that controls the exact movement of the spindle and table, removing material in carefully sequenced passes to achieve the required dimensions, features and surface finish. This level of computer control delivers consistency and accuracy that manual milling simply cannot match.
Based in Stockport, our CNC milling service supports CNC machining in Manchester and across the North West, complementing our CNC turning services to provide a complete in-house machining solution for our customers.
How Our CNC Milling Service Works
Every job that comes through our CNC milling service follows a structured process designed to deliver accurate, repeatable components on time. It starts with your drawing or CAD model and ends with a fully inspected, finished part ready for despatch.
Programming
Our programmers convert your drawing into a CNC program using CAM software, selecting the correct cutters, speeds, feeds and tool paths for the material and feature set required by the component.
Workholding & Setup
The raw material is clamped securely on the milling machine CNC table using a vice, clamps or a custom fixture. Accurate workholding is essential to prevent movement and vibration during cutting.
Roughing & Finishing
Roughing passes remove the bulk of the material quickly, followed by finishing passes that achieve the final dimensions, feature accuracy and surface finish specified on your drawing.
Inspection
Every component produced by our CNC milling service is checked using calibrated measuring equipment before despatch, confirming it meets your specification and drawing tolerances.
What Our CNC Milling Service Produces
Our milling machine CNC centres are capable of producing a wide variety of features and component types as part of our CNC milling service:
Plates, Blocks & Housings
Flat-faced components machined to precise thickness and flatness, with features added on multiple faces in a single setup where required.
Pockets & Profiled Features
Internal pockets, recesses and contoured profiles machined to tight tolerances, including curved and complex geometric shapes.
Bolt Hole Patterns
Accurately positioned hole patterns for mounting and fixing, drilled and tapped on the same milling machine CNC setup as the surrounding features.
Keyways & Slots
Slotted features machined directly into a component during milling. For deeper or specialist internal keyways, see our dedicated keyway slotting service.
Complex Multi-Face Parts
Components requiring features on several faces, machined using multiple setups or multi-axis milling machine CNC equipment to maintain accuracy throughout.
Finished & Ground Components
Milled components that require a finer finish or tighter tolerance on cylindrical features can be passed to our cylindrical grinding service for final finishing.
Materials We Mill
Our CNC milling service works with a wide range of materials including mild steel, stainless steel (grades 303, 304 and 316), aluminium alloys, brass, copper and tool steels, as well as engineering plastics such as Nylon, PEEK, Acetal and PTFE. The right milling machine CNC strategy — cutter selection, speeds and feeds — varies significantly depending on material, and our team selects the optimal approach for every job. For more detail on materials used across our wider Manchester precision engineering services, see our dedicated materials guide.

Frequently Asked Questions — CNC Milling Service
A milling machine CNC holds the workpiece stationary while a rotating cutting tool machines the surface — ideal for flat faces, pockets, slots and complex profiles. A CNC lathe rotates the workpiece while a stationary tool removes material, producing cylindrical parts. Many components need both — see our CNC turning services page for more on how the two processes compare.
Our CNC milling service routinely achieves tolerances of ±0.01mm to ±0.025mm depending on the material, feature size and component geometry. Where tighter tolerances are required on cylindrical features, our cylindrical grinding service can achieve ±0.005mm or better.
Yes, our milling machine CNC equipment can produce keyways, slots and pockets directly. For deeper internal keyways, splines or specialist slot geometries, we also offer a dedicated keyway slotting service using purpose-built slotting machines.
We mill mild steel, stainless steel, aluminium, brass, copper, tool steels and engineering plastics including Nylon, PEEK, Acetal and PTFE. Our team can advise on the most suitable material for your application as part of our wider Manchester precision engineering service.
