PwnCNC 4th Axis Rotary System for MASSO CNC – 100mm 4-Jaw Chuck

PwnCNC 4th Axis Rotary System for MASSO CNC

Add rotary carving, indexing, and cylindrical machining capability to a compatible PwnCNC or MASSO-controlled CNC.

This preassembled fourth-axis rotary system combines a 100mm four-jaw chuck, matching tailstock, and PwnCNC closed-loop 2Nm stepper motor. It is designed for plug-and-play use with supported PwnCNC machines and conversion kits, while other MASSO Touch installations may require additional power and inlet hardware.
