Industrial threehead grinder Color Machine Overview This industrial threehead grinder solves slow singlehead grinding and frequent tool changes by combining three grinding heads for coarse grinding, fine grinding, and polishing. The threeaxis design delivers a wide 8 inch diameter grinding area, higher output and better corner access so one machine can complete many jobs that previously required multiple passes or tools. Key benefits productivity: Three simultaneous heads cover an 8 inch diameter area, increasing grinding throughput and reducing job time. Versatile finishing: Use coarse discs for fast material removal, finer discs for smoothing, and diamond or water discs for polishing. Cleaner worksite: Builtin external vacuum port connects to a vacuum cleaner for dust control during operation. True edge and corner access: Removable enables 90 degree wall and edge grinding without blind spots. Easy to adjust: Sixspeed control from 800 to 2800 RPM adapts to different concrete conditions and disc types. Portable and ergonomic: Lightweight aluminum alloy and plastic construction with an adjustable extension pole for reaching or low areas. Main features Threeaxis efficiency grinding that covers an 8 inch diameter area per pass. 3800 W brushed pure copper motor for stable continuous power and long service life under heavy loads. Six gear speed adjustment, range 800 to 2800 RPM, for applications from rough grinding to polishing. Removable protective for vertical wall grinding and tight corner work, enabling 90 degree planing without blind spots. External vacuum cleaner port for connection to standard vacuums to reduce airborne dust. Adjustable extension pole from 113 to 168 cm to reach floors, walls and ceilings comfortably. Compact machine head length of 22 cm for access to corners and confined spaces. Lightweight net weight 7.41 kg for easier handling on site.
