Product Introduction
Electroplated diamond edge on a high-tensile stainless steel band, supplied as welded loops sized to your saw. For quartz glass, fused silica, quartz tube and rod, where edge chipping and coolant access decide the cut more than feed rate.

Edge and band construction
The diamond edge is a single-layer electroplated deposit. Grit retention depends on plating current, deposit thickness and edge exposure, so the plating line runs in-house and each batch is checked under magnification for grit distribution and missing spots before welding. The stainless backing is selected for fatigue resistance at the joint and for corrosion resistance during wet cutting. After welding, the joint is dressed flush, the loop is tensioned, and joint straightness is measured on an image measuring instrument. A blade that runs out at the joint will mark the quartz edge on every revolution; this check is part of the final inspection, not a sample check.
Quartz cutting notes
Quartz fractures under point loading, so the diamond edge grinds rather than shears. Use a continuous edge when chipping is the rejection criterion-quartz glass plates, fused silica windows, quartz tube where the cut face is visible or goes into a further process. Use a segmented or U-gullet edge on thicker quartz sections when heat build-up and debris packing slow the cut; the open gullet gives coolant direct access to the cut zone. Wet cutting is required in both cases. Grit 35/40 suits thicker sections and faster removal; 50/60 suits thinner walls and a finer edge. Feed and coolant flow are set by section thickness, not by a single recommended speed.
Custom supply
Widths from 10 mm to 80 mm are standard; 3 mm narrow strip is quoted for tight-radius work. Loops are welded to the length you specify, including machine-specific lengths. Grit, edge pattern, joint position and packaging can be fixed per order. Laser marking for brand, grit and length identification is available on bulk orders. Sipu produces the plated edge, welds the loop and inspects the joint in-house; the same line supplies diamond blades for glass, ceramic and sapphire, so grit and edge changes can be quoted without a new tooling cycle.
FAQ
Q: Continuous or segmented edge for quartz?
A: Continuous when chipping controls acceptance-quartz glass, fused silica, visible cut faces. Segmented or U-gullet when cutting thicker quartz and coolant access or debris removal is the limit. Both run wet.
Q: Which grit should I start with?
A: 35/40 for thicker quartz and faster removal; 50/60 for thinner sections and a finer edge. Finer grit is quoted on request. Grit choice follows the finish requirement and section thickness, not the saw brand.
Q: Can you weld to my machine length and supply narrow widths?
A: Yes. Standard widths are 10–80 mm; 3 mm is quoted for tight-radius quartz cuts. Loops are welded to your specified length, dressed flush and checked for joint straightness.
Q: What is the MOQ and delivery time?
A: MOQ is 5 blades. Stock widths ship in 48 hours. Welded-to-length loops and custom grit run 7–14 working days.
Q: How is the blade protected for sea freight?
A: The stainless band is protected against rust, the diamond edge and joint are wrapped with VCI paper, and the loop is packed in a reinforced plywood case. Packaging is specified for long sea transit, not just warehouse storage.
