CNC Milling and Turning – CNC Machining of Metal

Are you looking for a reliable partner for CNC machining?

We manufacture precise CNC milled and turned metal parts to drawing and CAD data – from prototypes through single parts and small batches to series production. Depending on the component geometry, we use CNC milling, 5-axis milling, CNC turning, long-turning or a combination of several machining processes. Materials processed include steel, stainless steel, aluminium, brass, copper, bronze and other machinable materials.Do you need a CNC component to drawing? Send us your drawing or CAD data, material, quantity and required tolerances. We will assess the suitable manufacturing route and provide you with a tailored quotation.

CNC milling or CNC turning – which process is suitable?

CNC milling and CNC turning are both part of machining metal, but differ fundamentally in the movement of the workpiece and the tool.

At the CNC milling rotates the cutting tool. The workpiece is usually clamped securely and moved relative to the tool on several axes. This makes it possible to produce, for example, flat surfaces, pockets, grooves, holes and complex three-dimensional contours.

At the CNC turning rotates the workpiece mainly instead. This process is therefore particularly suitable for rotationally symmetrical components such as shafts, axles, pins, bushes, sleeves and rings.

Many modern components require both processes. A turned basic body can, for example, also include additional cross-drilled holes, grooves or milled surfaces.

CNC Milling of Metal

In CNC milling, we manufacture individual metal parts to your technical documents.

Typical applications are:

Housings
Brackets and fixtures
Mechanical engineering components
Plates
Flanges
Fixture parts
Components with pockets and grooves
complex contours
components with multiple machining sides

For demanding geometries, we also offer 5-axis milling This allows multiple sides and complex three-dimensional contours to be machined efficiently and reduces the number of set-ups required.

CNC turning of metal

CNC turning is particularly suitable for workpieces with a rotationally symmetrical basic geometry.

Typical turned parts are:

Shafts
Axles
Pins
Sleeves
Bushings
Rings
Spacers
Threaded parts
Valve and machine components

With modern CNC turning centres, in addition to conventional turning operations, drilling, tapping and milling operations can also be carried out.

For small and slender precision parts made from bar material, the technology of long turning is also available.

CNC machining to drawing

The basis for reliable production is as much complete technical data as possible.

For an enquiry, ideally we need:

technical drawing as PDF
3D model, for example STEP
material or material number
Quantity
dimensional tolerances
form and positional tolerances
fits
threads
surface requirements
required post-processing
delivery date

The more precisely the functionally relevant features are defined, the more reliably production, inspection and costing can be planned.

Which metals do we machine?

Depending on component geometry, material condition and requirements, we machine, among other things:

Steel

Structural steels, free-cutting steels and various alloy steels for mechanical engineering, construction and industrial applications.

Stainless steel

Stainless steel for components with higher requirements for corrosion resistance, strength or surface finish.

Aluminium

Aluminium is particularly suitable for housings, fixtures, machine components and lightweight constructions thanks to its good machinability and low density.

Brass, bronze and copper

Non-ferrous metals are used, among other things, for machine, electrical, valve and precision components.

Other materials

Cast materials, titanium and other machinable materials are also possible depending on the specific project.

From single parts to series production

Our CNC machining is suitable for different production volumes.

Prototypes and single parts

For development, experimental construction, spare parts or new designs, individual components can be manufactured to drawing.

Small series

For recurring components, CNC programmes, tools and clamping concepts can be optimised.

Series production

For larger and recurring batch sizes, automated processes and optimised machining strategies enable economical production with reproducible results.

CNC milling and turning with modern machine technology

Various CNC machining centres and lathes are available for machining.

The machine park includes, among other things:

HAAS VF-2SSYT-EU CNC milling centre
FANUC ROBODRILL α-D28LiB5 ADV Plus Y500
Nakamura-Tome SC-100X² CNC turning centre
Tornos Swiss DT 26 long-turning automatic lathe

By combining different machines, machining can be adapted to the component geometry, dimensions, material and batch size.

Complete production of metal parts

CNC milled or turned parts are often part of larger assemblies.

In addition to machining, BlechProfis offers further metalworking processes, including:

Laser cutting
Bending and press braking
Punching
Welding
Spot welding
Deburring
Powder coating
Metal construction

This makes it possible, for suitable projects, to coordinate several production steps and realise complete components or assemblies.

Tolerances for CNC components

The achievable accuracy does not depend on the CNC machine alone. The key factors include:

Component size and geometry
Material
Clamping concept
Wall thicknesses
Number of setups
Tool accessibility
Temperature
Required surface quality

Function-critical dimensions and geometric requirements should therefore be clearly specified in the drawing.

For general dimensional tolerances, ISO 2768, for example, may be relevant; form, orientation, location and run-out tolerances are described in the GPS system, among others by ISO 1101.

What affects the price of CNC machining?

Manufacturing costs depend in particular on the following factors:

Raw material
Material dimensions
Component geometry
Machining volume
Number of machined sides
Number of setups
Machining time
Tool requirements
Tolerances
surface requirements
Inspection effort
Quantity
additional post-processing

Very tight tolerances should, where possible, be limited to features that are actually critical to function. This often makes a component significantly more economical to produce.

Enquire about CNC milled and turned parts

For a quick technical review, please send us, where possible:

Drawing + CAD data + material + quantity + tolerances + required post-processing + delivery date.

We will then check whether milling, turning, 5-axis machining, long-turning or a combination of the processes is suitable for your component.

Frequently asked questions about CNC milling and turning

What is the difference between CNC milling and CNC turning?

In CNC milling, the tool mainly rotates, whereas in CNC turning the workpiece rotates. Milling is particularly suitable for prismatic and complex contoured components, turning for rotationally symmetrical parts.

Can milling and turning be combined?

Yes. Many modern turning centres enable additional milling, drilling and thread-cutting operations. For more complex components, several machines and finishing processes can also be combined with one another.

Which materials can be CNC machined?

Among others, steel, stainless steel, aluminium, brass, bronze and copper. Other materials are possible depending on the alloy, geometry and requirements.

Do you also manufacture according to customer drawings?

Yes. CNC machining is carried out on the basis of your technical drawings and CAD data.

Do you manufacture prototypes and series production?

Depending on the component, both prototypes and individual parts as well as small batches and series production can be manufactured.
