What type of saw blade is needed for cutting UHPC panels?

UHPC panel cutting requires diamond saw blades (diamond segmented type). Core parameters: diamond grit 30/40 mesh, segment hardness HRC35-45, blade diameter 300-500mm. Qinglong uses dedicated diamond cutting blades combined with precision cutting techniques, achieving flat cut surfaces without edge chipping and tolerances ≤±1mm, meeting installation precision requirements.

1. Saw Blade Type Selection: Diamond Saw Blades Are the Core

Diamond saw blades match UHPC's high-strength characteristics. Blade type: diamond segmented blades (wet cutting) are preferred; diamond has high hardness (Mohs hardness 10) and can cut high-strength, high-density materials, preventing excessive wear of ordinary blades. Ordinary grinding wheel blades and alloy blades cannot cut UHPC and are prone to tooth chipping and burnout—Qinglong strictly prohibits the use of non-diamond blades. Blade parameters: diamond grit 30/40 mesh (coarse grit for rough cutting, fine grit for precision cutting), segment hardness HRC35-45 (matching UHPC strength), blade diameter selected according to panel thickness (300-400mm blades for 30mm thick panels). Qinglong customizes blade parameters for UHPC panels of different thicknesses, improving cutting efficiency by 30%.

2. Cutting Process and Saw Blade Usage Precautions

Standardized operation extends blade life and ensures cutting quality. Cutting method: wet cutting (water spray cooling) is adopted to prevent high temperatures during cutting from cracking UHPC panels or burning out blades. Qinglong maintains water pressure ≥0.3MPa during cutting for continuous cooling of the blade and cut surface. Cutting speed: linear speed is controlled at 30-50m/s with a feed rate of 50-100mm/min; going too fast easily causes edge chipping, while going too slow reduces efficiency. Qinglong controls speed through CNC cutting equipment, producing flat cut surfaces without burrs. Blade maintenance: check blade flatness before cutting (≤0.3mm), remove surface impurities from the blade, and promptly clean UHPC residue off the blade after cutting—Qinglong's blade maintenance extends service life by 50%. Safety protection: wear goggles and dust masks during cutting to avoid debris splatter. Qinglong installs protective guards in cutting areas, complying with safe operation standards.

3. Qinglong's Cutting Equipment and Construction Experience

Professional equipment and experience ensure cutting results. Cutting equipment: CNC cutting machines (precision ±0.1mm) paired with dedicated diamond blades; Qinglong's CNC equipment performs straight and curved cuts, meeting the requirements of shaped UHPC panels. Construction cases: for the Shanghai Astronomy Museum UHPC sculpture cutting, 400mm diamond segmented blades were used with curved cutting tolerance ≤±0.8mm; for on-site cutting of UHPC panels at the Shenzhen Yirui Biotechnology Building, 350mm diamond blades were used with cut surface perpendicularity ≤±1mm, requiring no secondary grinding. Qinglong tips: when cutting thick UHPC panels (>50mm), select blades with a diameter above 500mm and cut in multiple passes (cutting depth ≤20mm per pass) to prevent blade overload fracture, ensuring cutting safety and quality.
