CNC Rotational Axis 4th Axis: Transform your CNC machine with the capability to carve from various angles and positions, effortlessly processing complex parts with curves or angular features. Featuring a K11-100mm 3-jaw chuck, this dividing head for milling machine boasts an inner through-hole diameter of 0.9'/22 mm and a center height of 2.6'/65 mm, enabling you to tackle intricate designs with ease and precision. Precision at its Best: With a 6:1 reduction ratio, our indexing dividing head lowers the motor's rotation speed, providing a broader range of indexing angles for your machining tasks. It assists in precisely positioning workpieces to achieve the desired angles, ultimately enhancing machining accuracy. Additionally, the reduction in speed ensures smoother motor operation, reducing machine vibrations and noise for a quieter and more refined workspace. Stepper Motor Excellence: Equipped with the Nema23 2-phase stepper motor, it measures a compact 2.2x2.2x2
