Custom High Precision CNC Machined Quartz Structural Component
As the quartz glass has good thermal properties, it is usually applied in high temperature working environment as equipment components. With the help of CNC machine, our quartz structural part has high precision characteristics, which can well fitted with assembled part. The quartz component can work at 800-1000℃ for long time, which is a very ideal material for application which requires high temperature.
