4.5KW 220V 3.94 * 11.8in CNC Water-cooled Spindle, With ER20 Collet And 4 Bearings, Speed 24000RPM 400HZ, For Woodworking DIY Wood Engraving

• Specifications of woodworking CNC water-cooled spindle: φ3.94 x 11.8 in (diameter: 100mm x length: 300mm). power: 4.5 KW. voltage: 220V. current: 16A. chuck size: ER20Ø1~Ø13. bearings: 4 bearings (2*7005C/P4, 2*7003C/P4). frequency: 400 Hz. speed: 24000 R/min. runout: less than 0.005 mm. CNC spindle motors are mainly used in engraving machines or used with frequency converters. ER20 collet: CNC spindle collet is quenched with manganese steel, with a runout of less than 0.005mm, high precision, not easy to break, and increased stability of the working process. Material: The housing of the CNC spindle motor is made of high-quality stainless steel and equipped with a pure copper rotor. The upgraded 4-hole aviation plug ensures the stability and safety of the input power, and the rear dust cover prevents dust from entering the fuselage. 4-bearing design: The water-cooled spindle motor uses 4 P4-grade bearings (2*7005C/P4, 2*7003C/P4), with high precision, high density, high hardness, good stability and excellent anti-rust performance. High speed of 24000R/min can effectively increase work efficiency. Note: The spindle must be stopped for maintenance after 4 hours of continuous use! Main use: used for wood, stone, bamboo, ordinary PCB, PVC, PMMA, plastic, bamboo, two-tone board (ABS) and other non-metallic carving.
