[Bundle Discount]2.2KW ER20 Water Cooled Spindle Kit+80mm Spindle Mount

[Versatile Control] PWM Default for Mach3/GRBL The VFD is factory-set to PWM Mode for instant integration with Mach3, GRBL, and other CNC control boards. It also supports 0-10V Analog Control (with Forward/Reverse support) and Manual Panel Control. Note: High-voltage wiring is pre-assembled for safety. To switch to Manual Panel Control, simply adjust 2 parameters on the VFD. [High-Precision 2.2kW Power] 0.005mm Runout Accuracy Designed for spindle upgrades, this Φ80mm water-cooled spindle utilizes 4x P4-grade high-precision bearings. This advanced design ensures radial runout <0.005mm and delivers 3x longer service life than standard motors. Experience 24,000 RPM of consistent torque for smooth, chatter-free cuts. [ER20 Collet System] Larger Capacity & Versatility Upgrade from standard ER11 models with this ER20 collet system, supporting a wider range of shank sizes up to 13mm (1/2"). This increased capacity allows you to use larger, more rigid tools for aggressive material removal and faster feed rates. The kit includes 21mm and 30mm wrenches for quick, secure tool changes. [Complete Water Cooling] Silence & Durability Engineered for extended operation, the water-cooling system efficiently dissipates heat to prevent overheating during long carving sessions. The kit includes a dedicated 25W submersible pump and 6 meters of PU tubing. Enjoy a significantly quieter workspace with reduced noise and vibration compared to air-cooled spindles. [Wide Material Compatibility] From Wood to Aluminum This professional CNC spindle kit is perfectly matched for desktop CNC routers (e.g.,NBS-6040,NBX-5040) and modification projects. With its high torque and stable speed control, it effortlessly handles various materials including soft metals (Aluminum 6061, Brass), Hardwood, Plywood, MDF, Acrylic, Plastics, and PVC.
