Custom Machined Quartz Glass High Precision Components/Parts

Quartz glass CNC machining is a specialized manufacturing process that utilizes computer-controlled tools to fabricate high-performance components from fused silica. This technique is essential for producing intricate, high-precision parts that meet rigorous specifications across demanding industries. The exceptional properties of fused silica—including extreme thermal stability, high purity, superior optical clarity, and excellent chemical resistance—make it indispensable for advanced applications.

The process excels at creating complex geometries through precise quartz drilling and cutting, enabling the production of tight tolerance quartz parts with exceptional accuracy. These capabilities are critical for manufacturing semiconductor quartz parts, such as wafer carriers, etch shields, and process tubes, where contamination-free surfaces and dimensional perfection are mandatory.

Beyond semiconductors, CNC machined quartz components are vital in optical systems for lenses, windows, and mirrors requiring precise light transmission. Similarly, in the laboratory sector, the process fabricates custom fixtures, cuvettes, and reactor parts that must withstand corrosive environments and high temperatures. By combining advanced machinery with expert craftsmanship, manufacturers deliver robust, reliable precision components that meet the most challenging technical requirements.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
