Surface finishing to perfection
Aachener Quarzglas offers its customers a manufacturing depth that covers all processing steps along the production process of complex components made from quartz glass, technical glass, and glass ceramics. The polishing of glass and glass ceramic components completes the manufacturing portfolio at the Aachen production site.
Quartz glass and technical glass ceramics are high-tech materials whose further processing requires years of experience and mastery of various key technologies. For the production of optical glasses, we use modern single- and double-sided polishing machines. Additionally, high precision is also achievable through hand polishing, laser polishing, and flame polishing.
The polishing techniques available are optimally tailored to the individual quartz glass and glass ceramic components, allowing almost all desired contours and contour combinations to be polished. This ensures that Aachener Quarzglas provides you with precise and process-optimized surface finishing for one-off and series products made from optical quartz glass, borosilicate glass, float glass, ceramics, and other optical materials.
