CNC Milling

Complex milled components with high dimensional accuracy

CNC milling is essential for parts that require complex geometries, precise contours, or multiple operations on different faces. At Atlas MBD, our milling equipment handles everything from simple flat plates to intricate mechanical components with demanding tolerance requirements.

Milling Capabilities

Our CNC milling equipment can produce:

  • Flat and contoured surfaces with precision finishing
  • Pockets and cavities of various depths and shapes
  • Blind and through-holes with tight positional tolerances
  • Threaded holes and special thread profiles
  • Angled and inclined surfaces
  • Complex geometries and undercuts
  • High surface finish suitable for assembly and functional requirements

We use advanced CAM programming to optimise cutting strategies, reduce tool wear, and ensure consistent results across batches.

Materials

We mill a comprehensive range of materials:

Steel and Alloys

  • Carbon steel (S235, S355, C45)
  • Alloy steel (42CrMo4, 34CrMo4)
  • Stainless steel (1.4301, 1.4404)
  • Tool steel

Non-Ferrous Materials

  • Aluminium alloys (2024, 6061, 7075)
  • Brass and copper
  • Titanium alloys
  • Engineering plastics

Typical Applications

Milled parts are used across numerous industries:

  • Housings and enclosures for electrical and electronic equipment
  • Mounting plates, brackets and structural components
  • Jigs, fixtures and tooling
  • Prototype parts for design validation and testing
  • Series production of mechanical components
  • Aerospace and defence components
  • Medical device housings and assemblies

Why Choose Atlas MBD for CNC Milling

Multi-Axis Capability

Our modern CNC mills handle complex parts that would require multiple setups on older equipment, reducing lead times and improving accuracy.

Prototype to Production

From a single prototype to series production, we maintain the same quality standards. Your parts are inspected to specification every time.

Advanced Programming

Our CAM programming optimises each part for efficiency, minimises tool wear, and ensures consistent results. We take the time to get it right.

Responsive Service

Direct contact with our team means fast communication, quick responses to specification changes, and full transparency about your project timeline.

Frequently Asked Questions

FAQ

What tolerances can you achieve in CNC milling?
We achieve tolerances of IT7 to IT8 on standard milled surfaces and IT6 to IT7 on critical dimensions. Tighter tolerances (IT5 and finer) can be achieved through secondary operations such as grinding. The specific tolerance depends on part geometry, material, and surface finish requirements.
What part sizes can you mill?
Our milling equipment accommodates parts up to approximately 400 x 300 x 250 mm. Larger components can sometimes be accommodated by breaking them into sections or through special fixturing. Please discuss your size requirements when submitting an enquiry.
Can you mill complex geometries and pockets?
Yes, our multi-axis CNC milling equipment is well-suited to complex geometries, deep pockets, angled surfaces, and intricate details. We use advanced CAM programming and modern tools to achieve accurate and efficient results on difficult parts.
Which materials are suitable for CNC milling?
We mill steel, stainless steel, aluminium alloys, brass, copper, titanium, and engineering plastics. Different materials require different cutting strategies and tool selection, which we optimise for each project to ensure quality and cost efficiency.
What is the typical lead time for milled parts?
For prototypes, typical lead times are 2-3 weeks depending on complexity. Series production lead times are 3-6 weeks for most batch sizes. We provide a confirmed delivery date with every quotation, and we treat delivery schedules as commitments.
