Nakanishi Straight type spindle (7902) NR-4040 1 unit

Catalog number: NR-4040 Features: ●The E4000 series is the strongest spindle in the φ40mm class, achieving a maximum output of 1200W and a maximum torque of 100cN・m. ●High-precision machining is possible with a spindle runout accuracy of within 1μm, and the tool life is extended. ●Ceramic bearings are used, which are approximately twice as durable as steel bearings. ●A brushless motor is used, eliminating the need to replace carbon brushes and preventing carbon brush dust from entering the bearings, extending the tool life. ●The spindle and motor can be freely combined, allowing you to select the model that best suits your machining needs. ●An air-driven catching system is used, allowing for quick and easy replacement of the collet holder.
