What Type of Saw Blade Is Needed for Cutting UHPC Panels? Precision Machining and Qinglong Group Tool Specifications

Cutting UHPC panels requires "diamond saw blades" specialized for high-strength brittle materials; their core parameters — "diamond concentration, bond hardness, water cooling method, and cutting speed" — must match the hardness of UHPC (Mohs hardness 6-7). Qinglong Group's process standards specify: for dry cutting, use sintered diamond saw blades (diameter ≤350mm, concentration 35-40%); for wet cutting, use electroplated diamond saw blades (diameter ≤500mm, requiring continuous water cooling). At our Nanning production base, we use Italian-made professional bridge cutting machines (rotation speed 2800rpm) fitted with 350mm diameter diamond saw blades (segment width 3.5mm). When cutting 30mm thick UHPC panels, the feed speed is controlled at 0.5-1.0m/min, achieving cut straightness error ≤0.5mm with no edge chipping. Professional cutting is the foundation for ensuring installation precision and aesthetics.

Blade Selection Based on Material Characteristics

UHPC contains hard aggregates (quartz sand, Mohs hardness 7), which cause ordinary saw blades to wear extremely fast. Diamond saw blades grind with diamond particles, offering long life and clean cuts. We select the tooth pattern according to panel thickness: continuous rim for thin panels (<20mm), segmented teeth for thick panels.

Cutting Process Control Is Key to Quality

Water cooling is essential to prevent heat damage to the UHPC matrix (strength decreases above 60℃). Feed speed must be uniform — too fast causes edge chipping, too slow reduces efficiency. We train dedicated cutting operators who work with certification.

Safety and Environmental Measures Are Indispensable

Cutting generates large amounts of silica-containing dust, requiring a dust removal system (removal efficiency ≥99%). Operators wear protective goggles and masks. Wastewater is settled and recycled, achieving zero discharge.

To do a good job, one must first sharpen one's tools. Through standardized operations, Qinglong Group makes cutting no longer a challenge.
