CNC Turning

Precision CNC turning of rotating parts to ±0.01 mm tolerance for industry.

Material properties

Advanced CNC turning for demanding applications

Modern CNC turning is a key manufacturing process for producing rotating parts with strict geometric requirements. We use high-end turning centres that combine high rigidity with dynamic drives. These machines handle not only conventional external and internal metal turning but, thanks to driven tools, also milling operations in a single setup. The result is reduced non-cutting time and the elimination of errors caused by re-clamping.

Our machine park includes multi-axis CNC lathes with counter-spindles and automatic bar feeders. This configuration is ideal for uninterrupted series production where maximum efficiency is required. For automotive and aerospace buyers it means a guarantee that deadlines will be met. We calibrate our machines to DIN standards for repeatable production. Key technological advantages include:

  • Multi-axis machining: Y-axis integration for complete machining of complex parts.
  • Driven tools: Drilling and thread cutting performed directly on the lathe.
  • Automation: Bar feeders for continuous operation and reduced costs.

Precision metal machining and material options

Industrial production accepts no compromises, which is why our precision metal machining is designed for tolerances within ±0.01 mm. This level is essential for fitted components and bearing seats. We achieve it thanks to premium cutting tools and optimised cutting conditions. High-pressure coolant systems ensure perfect chip evacuation.

We process a broad range of materials, from structural steels to difficult-to-machine alloys. We turn 304 and 316L stainless steels for the chemical industry. For the aerospace sector we machine titanium and duralumin, where the strength-to-weight ratio is critical. Every material requires a specific strategy defined in our CAM systems. Surface and geometry parameters:

  • Surface roughness: We routinely achieve Ra values from 0.4 µm.
  • Roundness: Strict adherence to form tolerances per ISO 2768-fH.
  • Hardened parts: Hard turning of materials up to 60 HRC.

Parts manufactured to drawing

Our custom manufacturing of parts to drawing covers the requirements of demanding industries. For the automotive industry we supply shafts, pins and pulleys that withstand extreme loads. In hydraulics we turn piston rods and valves that must be absolutely leak-tight. Every project starts with a thorough analysis of the customer's 3D models.

Production preparation includes toolpath simulation, which optimises machine time. This approach lets us handle both high-volume orders and prototype production efficiently. Design engineers receive physical parts for testing within a short time. Flexibility means a fast response to design changes. Most frequently manufactured components:

  • Shafts: Drive elements with precise keyways and involute splines.
  • Flanges: Components for safe torque transmission in machinery.
  • Bushings: Wear-resistant parts for joints and mechanism seats.

Quality control and logistics across the EU

The quality of machined parts requires a comprehensive measurement system. In our climate-controlled laboratory we use 3D coordinate measuring machines (CMM) to verify critical dimensions. We use digital profilometers for roughness checks and optical instruments for complex contours. Every batch passes multi-stage inspection, from first-article approval through to final inspection.

Our quality management system complies with ISO 9001:2015, which guarantees process traceability. Our plant is located in Ladce, Slovakia, in the heart of Central Europe, so we ship finished parts throughout the European Union. For B2B partners we guarantee:

  • Material certificates: 3.1 certificates to EN 10204 supplied with deliveries.
  • Buffer stock: Safety stock maintained directly in our warehouses.
  • Secure transport: Parts fixed in protective netting to prevent damage.

How CNC machining works for CNC Turning

01
Enquiry and drawing review

We receive your 2D/3D drawing, assess manufacturability, propose the optimal material and send you an accurate quotation.

02
CAM programming and production setup

Our engineers in Ladce create the CNC program, set cutting parameters and prepare the tooling for maximum efficiency.

03
First article production and fine-tuning

We turn a first-article part that undergoes strict dimensional inspection. Once approved, series production starts.

04
Precision CNC turning

Production on modern lathes, holding tight tolerances down to ±0.01 mm and the specified surface roughness.

05
Final inspection and dispatch

Every part goes through final inspection. The parts are then securely packed and shipped directly to you.

Frequently asked questions about CNC machining CNC Turning

What tolerances can you achieve in CNC turning?
At Metal One we routinely achieve tolerances of ±0.01 mm, depending on the material type and part geometry.
Which materials do you turn most often?
We machine a wide range of materials including structural and stainless steel, aluminium, brass, copper and engineering plastics (POM, PTFE).
What is your minimum order quantity for CNC turning?
We focus on small and medium batch production. We commonly handle orders from tens up to thousands of pieces.
What are your standard lead times?
Standard lead time is 2 to 4 weeks from drawing approval, depending on current capacity utilisation at our Ladce plant and material availability.
How do you calculate the price of a turned part?
The price depends on material cost, programming complexity, machine time and batch size. Send us a 3D model or 2D drawing and we will prepare an exact quotation.
Do you also arrange surface finishing for turned parts?
Yes. Working with our verified partners we can arrange anodising, zinc plating, hardening or black oxide finishing of completed parts.
