CNC Milling

Precision 3-axis and 5-axis CNC milling of metals to ±0.01 mm tolerance

Material properties

The technology behind precision CNC milling

Machining complex geometric shapes calls for high-end machining centres that combine rigidity with dynamic performance. Our machine park is built around modern 3-axis and 5-axis milling centres, which allow continuous machining in several planes at once. This reduces the number of setups, directly minimising form and position deviations. We deliver precision metal machining with a guaranteed tolerance of ±0.01 mm, meeting the strict requirements of design engineers in the automotive and aerospace industries.

Continuous five-axis metal milling opens up the production of impellers, turbine blades and complex moulds. Spindles running at up to 18,000 rpm with through-tool internal coolant ensure optimal chip evacuation and extend insert life. This delivers not only excellent dimensional stability but also shorter machine times while maintaining the required surface quality.

Every process route is optimised in advanced CAM software. Programmers simulate toolpaths before the cycle starts, eliminating collision risk and optimising the cutting process. The result is efficient production that meets the technical specifications defined in ISO 2768-mK and stricter standards.

Metal machining and logistics across Europe

Our production facility sits in a strategic location that enables fast, flexible distribution of finished parts. Our plant in Ladce, Slovakia, is an ideal hub for deliveries within Slovakia and for export to European Union countries. Proximity to major transport corridors reduces logistics costs and shortens lead times for our B2B partners.

We ensure a steady supply for industrial companies across the surrounding engineering region, home to numerous machinery and automotive subcontractors. Shipping components to any other region according to the client's purchasing requirements is a matter of course.

The logistics process is fully integrated with our ERP system, guaranteeing accurate order tracking from material receipt through to final dispatch. Packing of machined parts follows strict internal procedures to prevent mechanical damage or corrosion in transit. We use special anti-corrosion films and custom-designed fixtures for geometrically complex components.

Parts manufactured to drawing

Successful cooperation with design offices rests on strict adherence to the specified parameters. Parts are manufactured to drawing from supplied 2D drawings and 3D models in STEP or IGES format. Our engineers analyse the requirements for material, heat treatment and surface finishing in order to propose the most efficient production route.

We process a broad range of technical materials, from common structural steels to difficult-to-machine alloys. The most frequently milled materials include:

  • Tool and heat-treated steels: for moulds, punches and highly loaded machine assemblies.
  • Aerospace aluminium (EN AW 7075): for components requiring low weight and high strength.
  • Stainless steels (AISI 304, 316L): for the food and chemical industries.
  • Titanium alloys and brass: for specific applications in medical technology and electrical engineering.

For each material we select a specific cutting tool geometry and set of cutting conditions. This approach minimises residual stress induced in the workpiece and prevents subsequent distortion once it is released from the fixture.

Metrology and quality control of machined parts

Precision CNC milling is impossible without rigorous inspection of dimensions and geometric tolerances. In our climate-controlled metrology laboratory we use 3D coordinate measuring machines (CMM) to verify that the manufactured part conforms to the CAD model. Every production batch undergoes in-process and final inspection in accordance with ISO 9001:2015.

Alongside dimensional accuracy we place strong emphasis on machined surface quality. Roughness testers are used to evaluate Ra and Rz parameters, and we routinely achieve surface roughness from 0.4 µm. To achieve a mirror finish or a specific texture we apply finishing operations such as fine milling with coated solid carbide cutters.

Measurement reports and 3.1 material certificates to EN 10204 are issued automatically with delivered components. These documents give buyers and engineers confidence that the supplied parts meet all the mechanical and chemical properties defined in the original specification.

Industrial applications and delivery flexibility

Our capacity is adapted to varied market requirements, from functional prototypes through to medium-sized batches of thousands of pieces. For the automotive industry we supply clamping fixtures, welding jigs and components for assembly lines. In the aerospace sector we focus on structural elements for interiors and fuel systems, where weight and absolute reliability are critical.

Production flexibility is supported by pallet changers and automated blank loading. These systems enable unattended operation during night shifts, significantly increasing overall productivity and reducing the unit cost per part. Customers benefit from an excellent price-performance ratio while retaining top quality.

We invest continuously in renewing our machine park and training our programmers. This allows us to respond to the most demanding technological challenges and to provide comprehensive machining services. We are a stable partner for companies looking for reliability, precision and an innovative approach to manufacturing metal components.

How CNC machining works for CNC Milling

01
Enquiry and document review

We receive your 3D model and 2D drawing. Our engineers in Ladce assess manufacturability and propose the optimal milling strategy.

02
Quotation and CAM programming

We prepare an accurate quotation. Once approved, we create efficient toolpaths in CAM software for our CNC milling centres.

03
Setup and CNC milling

Precise clamping of the blank and the machining itself on 3-axis or 5-axis machines, with strict tolerances maintained throughout.

04
Final quality inspection

Measurement of key dimensions and geometry to ±0.01 mm accuracy. A detailed measurement report can be supplied with every order.

05
Packing and dispatch

Finished milled parts are securely packed against mechanical damage and corrosion, then shipped directly to you.

Frequently asked questions about CNC machining CNC Milling

What tolerances do you achieve in CNC milling?
At Metal One we routinely guarantee machining accuracy and tolerances of ±0.01 mm, depending on the specific material and part geometry.
Which materials can you mill on your CNC machines?
We machine a wide range of materials including structural, tool and stainless steels, aluminium alloys, brass, copper and engineering plastics (e.g. POM, PEEK).
What is your minimum order quantity for CNC milling?
We are flexible. We handle custom one-off production (prototypes) as well as small and medium batch production. We accept orders from a single piece.
What are your standard lead times for milled parts?
Standard lead time from our facility in Ladce is 2 to 4 weeks from order confirmation. The exact date depends on part complexity and material availability.
How is the price for a milled part calculated?
The price depends on the complexity of the 3D model, the machinability of the material, the required tolerances (±0.01 mm accuracy requires longer machining and inspection time) and the batch size.
In which formats should we send drawings and 3D models?
For fast, error-free processing we prefer 3D models in STEP (.stp) or IGES format and 2D drawings in PDF with clearly marked tolerances and surface roughness.
