CNC – cost-effective and flexible?

Customers often ask: "Can you supply low-cost CNC-machined parts?"

The answer is clearly yes! This is because thanks to our flexibility, quality standards and high degree of in-house production we are able to beat any competitor when it comes to cost-effective manufacturing.
Using an array of highly modern machines with flexible organisation and consistently applied CAD/CAM technology we are in a position to supply top quality turned and milled parts with astonishing speed ranging from prototypes to series with 20,000 parts.

We process parts in aluminium, steel, stainless steel and titanium and are also able to manufacture extremely complex part geometries.

Speed and quality 

The two characteristics of speed and quality are sometimes difficult to reconcile – but not with us. We achieve astonishingly short delivery times through our human resources, flexible organisation and ingenious solutions with in-house manufactured fixtures. If required, we can also produce in three shifts. Apart from that, we anodise aluminium parts in-house and have excellent contacts to electroplating companies. As a result, it is not uncommon for us to produce a small series of turned or milled parts in two weeks, starting with the design drawing up to electroplating, anodising or heat treatment, with the highest precision and without having to compromise.

We do not produce in the millions

A production series of 20,000 parts is routine for us. The same is true for special solutions, small series and prototypes. We are not geared to high volumes with hundreds of thousands of parts. Our strength is in the manufacture of turned and milled parts which are particularly demanding. In the process, our priority is to fine-tune the production process for the application in question.

Strenge Qualitätsicherung

The quality assurance is managed solely by us. We set the highest standards and inspect each separate production process for compliance.

We are certified according to DIN EN ISO 9001 and 14001.

CNC water jet cutting

Those familiar with modern production technology will already be aware of the advantages of water jet cutting. The most important of these advantages are:

5-Achsen Wasserstrahlanlage

Our water jet cutting machine

Perndorfer WSS cantilever

  • Movement range:  4,000 x 2,000 mm
  • 60° cutting head for taper-free cuts
  • Bevels to prepare for welds: angle up to 60° possible
  • Workpiece weight: up to 1,000 kg/m2
  • 5 quality grades
  • Cutting tolerance: +/- 0.1 mm

Flexibility

Thanks to vector-controlled cutting, the cutting head is able to move in 5 axes. This opens up a host of cost-cutting features:

  • Bevel cuts up to an angle of 60°
  • Drilled holes and cut-outs
  • Bevel parts, welding preparations, counterbores
  • Produce and mark: cutting and engraving in a single operation

5 quality grades

Depending on the requirements, a number of quality steps are available which can be clearly calculated and differentiated:

1. Fine cut

Highest dimensional accuracy, fine surface

2. Quality cut

High dimensional accuracy, grooves hardly visible

3. Standard cut

Smooth cutting surface, path of the jet is visible

4. Production cut

Visible grooves. Ideal for semi-finished products, welding parts

5. Separation cut

Rough cut to separate material

Anodising

Parts anodised in our own company

This is an unbeatable advantage when it comes CNC parts in aluminium.
There are hardly any producers of CNC-machined parts who are also able to anodise the parts in their own company. This is because this highly specialised surface treatment technology is difficult to master. But not for Olejnik. Our roots are in the area of technical equipment used for surface finishing. For many years we have maintained close professional contact to electroplating and anodising companies. The next logical step was to have our own anodising plant. This addition quickly paid for itself. Our customers benefit from numerous advantages:
The complete process is under our control and therefore we are able to agree to binding delivery dates.

Our processes:

Standard anodising (5 – 25 microns)
Hard-anodising (up to 100 microns)
Decorative and technical anodising
A wide range of colourings is available
