CNC machining for glass ceramics

We have specialized for decades in the processing of special materials, most notably glass ceramics.

MACOR^®

When it comes to machining glass ceramics, we trust one material above all others: Macor^®. Macor^® combines the performance of a technical ceramic material with the versatility of a high-performance polymer, making it extremely easy to work. With this material CNC turning and CNC milling using conventional tools and CNC machines can be used to manufacture even the most complex of molded parts and the smallest precision parts. If you need the performance of a technical ceramic material in pieces with a complex shape, Macor^® glass ceramics are perfect for you.

This machining process facilitates flexible, geometrically accurate manufacturing without the need for afterburning. This significantly reduces the time between development and application and cuts down on costs.

High technical standards

Our plants are designed to enable highly efficient manufacturing for Macor^® components that need to meet high standards of technical quality.

Did you know?

The working temperature of Macor^® for continuous operation is 800°C, with peaks of 1,000°C.
It can achieve machining tolerances of up to 0.01 mm and a surface quality of less than Ra 0.1.
The material has low thermal conductivity, and remains a good thermal insulator even at high temperatures.
It is an excellent electrical insulator, and has been used successfully in the electronics and semiconductor industry.
Non-porous: It does not emit any gases when thoroughly heated in the furnace, making it the perfect material for ultra-high-vacuum applications.
High strength and rigidity.
Unlike high-temperature plastics, the material does not creep or warp.
The material is radiation-resistant, which has also made it popular in nuclear and aerospace applications.
It can be metallized in thin or thick layers, brazed, and bonded using epoxy resin or frits.
It is non-wetting, has zero porosity and, unlike ductile materials, does not warp.

Photoveel N^® – The high-performance ceramic material

In addition to Macor®, we can also machine the extremely hard ceramic material Photoveel N®, which has an incredibly high bending strength, with the utmost precision. We do this using our own in-house production process and our years of expertise with the product and in this field.

Thanks to its hardness and bending strength, Photoveel N® offers enormous advantages, especially in the fields of high vacuum, aerospace and nuclear technology.
