Description
Frosted Quartz Ring
Product description:
Frosted Quartz Ring is widely used in high temperature resistant machine or other field. With the help of CNC machine tools and according to customer drawings, Laseri factory can produce customized high temperature resistant quartz glass parts of various sizes and shapes to meet the requirements of different customers. Because depending on the use, the machining accuracy can be achieved from ±0.5mm to ±0.02mm. By changing different CNC tools, different shapes can be processed. For more questions, please send email to me.
