Milling is a machining process to subtract material. Material is removed using a milling tool rotating around its axis at high speed. We use 4-axis portal milling machines to mill shaped parts from plates and to make tools. With 4-axis milling, a drill head is moved along the X-Y-Z axes to machine the workpiece. In this way, straight sheets, 3D bodies and bores can be milled. We use CAM programs for numerical control to create a milling program. This enables us to achieve a high level of precision and to manufacture automatically and repeatably. With automatic mill head changers, we can carry out various processing steps quickly.

Special Properties of Plastic, Fleece and Wood

Unlike many other companies, we generally do not process metals, but plastics, nonwovens and wood. This differs in the type of milling machines we use, but also in the milling heads and the required material knowledge.

Optimizing Milling

The basis for the best milling results is to fix the part or the board to be milled, for example using a multi-zone vacuum table. This way we can create warp-free workpieces. A milling head used for plastic is very sharp and moves extremely quickly. There are special spindles specially designed for plastics. Consistent cooling of tools and workpieces via minimum lubrication / spray cooling is necessary for plastic milling, since these can melt even at low temperatures. This requires a precise adaptation of the milling head to the material. Since plastics are very different, it is often necessary to test here to find the optimal combination of moving speed and rotation.

How milling works

Precise Coordination and Programming

Every project and every material is individual and we also map this process with us. To do this, we combine CAM-controlled programming with test trials in order to find the optimal processing.
  • CAM-Programming

    We program in 2D and 3D depending on the geometry of the part to be manufactured

  • Prototype Tests

    After the first programming, we create prototypes to identify problem areas that modeling on the computer does not show

  • Milling in Series

    With the knowledge from the first two steps, we then create the final program and save it permanently to ensure repetition security
