Heavy Duty 4th Axis Rotary Indexing Head With Nema 34 Stepper Motor 100mm Chuck Top Shelf Specs Built Like A Tank For Smooth Cnc Milling And Shop Rigs

Single Heavy Duty 4th Axis Rotary Indexer For CNC Machining
✔️ NEMA 34 stepper powers 3:1 gear ratio for steady spindle control

A single heavy duty rotary indexer mounts straight onto your milling table to spin cylindrical blanks while you cut, carve, or drill complete circles. Shop hands grip steel tubes, hardwood dowels, or round aluminum rods on the four jaw mounting and run continuous shaping jobs with zero guesswork.

✅ 3:1 deceleration ratio cuts vibration during tight curves
✅ 0.6 degree stepping accuracy locks positions every revolution
✅ One hundred millimeter chuck opens wide to grip thick stock fast
✅ Sixty five millimeter center height lifts heavy blanks safely high

💡 How does a low backlash index head improve repeatable drilling angles? This setup removes rotational play so every angular cut hits the exact same mark again and again. - A heavy torque motor combined with a planetary gear set eliminates slack between operations so your hole alignment stays dead on mile after mile. - The solid mounting base absorbs cutting forces and keeps the shaft locked under heavy side loads without slipping out of position. - Quick swap chucks let you flip between concentric and offset patterns without pulling tools off the bench making it handy for production runs.
