Quartz Glass Cutting Solutions – Sanding-Effect Finish for Semiconductor & Optical Applications

Endless diamond wire saw is the most effective quartz glass cutting solution for fused silica and crystal quartz. The horizontal SH series machines deliver a sanding-effect surface finish with no wire marks, stable edge quality, and rotary cutting capability for tubes and cylinders. The combination of high tension (150–200N) and white mineral oil cooling prevents thermal stress and edge chipping — the two main failure modes in quartz glass cutting.

Feed speed for quartz glass cutting is 2–10 mm/min, adjusted based on the specific grade and cross-section. Semiconductor-grade fused silica typically requires 2–4 mm/min for maximum surface quality. Industrial quartz with less stringent surface requirements can be cut at higher feed rates within the range. Our engineers help optimize feed speed during the free test cut service.

Yes — this is one of the key advantages of Vimfun's quartz glass cutting solution. The SH-R series horizontal rotary wire saws rotate the quartz tube or rod while the wire cuts horizontally, producing clean flat cross-sections from cylindrical stock. This is critical for semiconductor process tubes, optical fiber preforms, and quartz crucibles, where blade-saw cuts produce chipping on the curved tube wall.

Quartz glass cut with an endless diamond wire saw produces a sanding-effect surface finish — uniform abrasive texture with no directional wire marks. This is a significant improvement over reciprocating wire saws, which leave reversal patterns, and blade saws, which leave concentric arc marks. The surface is suitable for optical-grade and semiconductor-grade quartz applications with minimal secondary polishing. This consistent, mark-free result is one of the defining advantages of Vimfun's quartz glass cutting solutions over conventional methods.

Both fused silica (amorphous) and crystal quartz (crystalline) are cut with the same parameter range, but crystal quartz is slightly more sensitive to cleavage planes during cutting. For crystal quartz, slightly more conservative feed speeds and careful orientation of the cutting direction relative to crystal axes can minimize cleavage-related fractures. Our engineers can advise on crystal orientation considerations during the test cut process.

The SH60-R handles quartz workpieces up to Ø 600 × H 400 mm. For larger applications — optical fiber preforms, industrial quartz crucibles, and large fused silica blocks — the SH150-R (up to Ø 1500mm) and SH300-R (up to Ø 3000mm) are available. For non-standard sizes, Vimfun provides custom machine configurations to match specific workpiece dimensions.
