Manufacturing and machining technologies

With over 69 years of know-how, extensive development expertise, and the most modern technologies, the Berger Group can manufacture everything your business desires – from individual components, to the most complex assemblies and component groups. As a worldwide manufacturer of high-precision parts, we have specialized in brass, aluminum and steel (chrome-nickel steels), non-rusting and acid-resistant steels, case-hardened and tempered steels that are ready for installation, both off the shelf and as cast or forged blanks. We are ready to assist you, whether your needs involve prototypes or yearly production volumes of more than 20 million components.

Using the very latest high-tech machines that can handle any type of application, Berger is poised to serve as a business partner that can advise customers on how to optimize production procedures that will benefit any specific need. Consider allowing Berger to be a part of your business – we are ready to offer our expertise!

• Machining
• Deburring
• PECM
• Surface treatment
• Heat treatment
• Cleaning

We use a number of different procedures to remove from components the burrs created by turning and milling. Here too Berger is excellently set up and makes use of various automated and robot-supported deburring procedures. The aim here is to fine-finish, compact and smooth surfaces so as to give a homogeneous appearance. Depending on the material, the size of the component and subsequent machining or processing, we can choose the correct procedure from among:

• Sand-blasting
• Glass bead-blasting
• CO₂-blasting
• Tumbling
  In addition to deburring and rounding off edges, tumbling is also used for smoothing and polishing, cleaning, degreasing and desoldering.
• High-pressure water jet
  In the innovative high-pressure water jet procedure water is directed at component areas where there are burrs by means of multiple rotating jets or individual lances. This deforms the burr and breaks it off from the component.
• TEM
  Thermal deburring (or Thermal Energy Machining TEM), also called explosive deburring, uses the combustion principle to remove thin protruding burrs by igniting a gas mixture at high temperatures in a so-called deburring chamber. This makes it possible to deburr places that are hard to access, such as the intersection of two drilled holes in the component.
• ECM
  Materials that are difficult to cut or complicated components with burrs that are difficult to reach can be deburred by using Electrochemical Machining (ECM). Since there is no contact between the tool and the workpiece when using this procedure, no mechanical forces are transferred either.
• Chemical deburring
• Brushing

Maximum precision to meet your needs – with this goal in mind Berger has further developed Precision Electrochemical Machining (PECM) together with machine manufacturers and customers over many years. The resulting technology that has been developed is applied worldwide by Berger in a way that is unique and allows the highest degree of precision with regards to the precision of surfaces and contours.

This means that time-consuming and cost-intensive post-processing is not required any longer thanks to a 100% burr-free geometry. Depending on the process and facility design, the removal of several millimeters of material is no problem. You as our customer profit from an extremely capable manufacturing process, which from an economic point of view provides enormous advantages compared to conventional production methods such as milling, for example.

More information

In our capacity as a specialist for precision technology, we work closely together with experienced partners and also finish surfaces to your individual specifications as part of the production process. What is understood by surface treatment is the totality of all the technologies to change the properties of surfaces. Using the procedures for surface technology, the surface can be optimized for a specific requirements profile and hence fulfill additional functions.
