【Key Machine Features & Advantages】
  • Precision blade re-sharpening machine engineered for tungsten carbide circular blades, supporting both dry and wet grinding modes.
  • Eliminates production downtime from outsourcing sharpening, saving turnaround time and extending blade life.
  • Adjustable cutting bevel angle from 17° to 22° (standard preset angle is 18°).
  • High-precision spindle operating at 3,000 RPM, equipped with a diamond grinding wheel (125D-6W-2X-35T-14E-31.75H).
  • Fast grinding cycle: takes only approx. 20 minutes per blade; recommended sharpening every 1~2 days under standard 8-hr/day production.
  • Closed-loop coolant system: features an internal recirculation tank and splash enclosure to preserve wheel life and maintain a clean shop floor.
  • Five core modules: heavy-duty main frame, electric control system, coolant system, precision grinding assembly, and micro-feed mechanism.
