Milling of electrical insulants and other materials

Thanks to the high versatility of our CNC machines, we can also mill many special materials. Most often these are electrical insulants, mica materials, but also for example materials for playground construction and we can also mill rubber. The working area of our two CNC milling machines is 3100 x 2100 mm and we can produce really large parts.

What we can solve:

Our modern CNC milling machines can handle a wide range of materials. In principle, we can mill (or cut) all materials from soft ones (foams, microporous materials), through industrial engineering plastics, wood to non-ferrous metals. We can handle a wide range of special materials. These include electrical insulants, mica materials, sandwich boards, composites and many other materials. Thanks to our production capacity, we can produce prototypes and small batches, but we can also cope with large series production. With laser engraving technology we can also engrave any graphic motif or make part markings as required. If necessary, we can also use our optical measuring instrument for product inspection, which guarantees the quality with a measuring protocol.

Materials

How is CNC milling of electrical insulants and other materials performed?

Inquire CNC milling of electrical insulators
01
Determination of requirements, assessment of technical drawing
On the basis of a technical drawing, or by measuring a sample, we will assess the manufacturability of the part and prepare a non-binding quotation.
02
Production preparation
Our CNC machine operators will prepare the production technology according to the specific part. Here, the specific milling requirements of each material must be taken into account. We therefore use dedicated milling tools with the appropriate geometry for the selected material.
03
Production of milled parts from electrical insulators
Then comes the production itself. Thanks to our modern CNC milling machines, the machining of electrical insulators and many other materials is precise, fast and efficient. Again, however, specific processing requirements must be taken into account and the production process adapted accordingly. Other material processing operations may follow.
04
Part inspection, measurement
The finished milled part is finally cleaned, inspected, measured and prepared for safe dispatch. We use integrated measuring probes to measure the parts, which we also use for precise alignment of the product on the machine. For checking dimensional tolerances, we can also use our optical measuring device, which measures the part really accurately and prepares a measurement report, thanks to which we can guarantee that the required tolerances are met.

Frequently Asked Questions

CNC milling is suitable for a wide range of electrical insulation materials such as pertinax, texite, glass-textile, G10/G11, hardened composites, engineering plastics or epoxy and fibreglass insulation boards.

These parts are mainly used in electrical engineering, power engineering, mechanical engineering and automation. Typical applications are insulating pads, carrier plates, spacers, covers, switchgear components or parts of electrical equipment.

CNC technology enables the production of very precise parts with high repeatability. The advantage is the possibility of machining complex shapes, holes, grooves and thin-walled components while maintaining good electrical insulation properties of the material.

For example, composite materials, carbon, sandwich boards, technical ceramics, rubber materials, foam boards or special industrial laminates can also be CNC milled.

Some materials contain abrasive components, such as glass fibres or carbon fibres, which increase tool wear. Therefore, the correct choice of cutters, cutting cooling parameters and effective dust extraction during machining are important.

When milling electrical insulants, it is important to minimize the formation of burrs, delamination or overheating of the material. Properly set cutting conditions help to maintain the mechanical and electrical properties of the final part.
