Many engineers and buyers quickly discover that machining fused quartz is very different from machining metals or ceramics. If you’re searching for a professional guide that explains how CNC machining quartz works and how to choose a reliable manufacturer, this article will help you understand the process, materials, equipment, and capabilities offered by companies like FGQuartz.
Understanding CNC Machining Quartz for High-Precision Applications
CNC machining quartz requires unique tools and processes because fused quartz is extremely hard, brittle, and sensitive to micro-cracks.
Why Fused Quartz Is Difficult to Machine
Fused quartz has a Mohs hardness of 6–7, low thermal expansion, and high purity. While these properties make it ideal for semiconductor and optical applications, they also create challenges during milling or drilling.
The Importance of Diamond Tools in Quartz Machining
Quartz can only be machined with diamond grinding tools. Standard milling cutters cannot withstand the hardness and brittle structure of fused silica.
Coolant and Feed Rate Requirements
To avoid cracks, CNC machines use slow feed rates, plenty of coolant, and multi-step grinding passes.
High-Purity Quartz Materials Used in CNC Machining
When selecting a quartz machining supplier, material purity is crucial. Semiconductor-grade fused quartz must contain extremely low metallic impurities.
Types of Quartz Suitable for CNC Machining
-
Fused quartz
-
Fused silica
-
Synthetic quartz
-
UV-grade optical quartz
These materials support applications in high-temperature, optical, and semiconductor environments.
Why Purity Matters in Semiconductor Components
Any metallic contamination can affect wafer processing, so high-purity quartz is preferred for diffusion, etching, and cleaning equipment.
