Straight Up Precision 4th Axis Gearbox For CNC Router, Hella Tough Rotary Three Jaw 100mm Chuck With 20 To 1 Ratio, Smooth Engraving Tailstock, Sweet Upgrade For Wood And Metal Jobs

CNC Fourth Axis Rotary Table Kit With Chuck
✔️ K11 chuck, 20 to 1 ratio, 70mm tailstock, fast setup, runs smooth

This rotary indexing attachment bolts straight onto your CNC router plate to handle four sided machining workflows. It locks down cylinders and complex shapes while spinning steadily on the A axis, which makes carving spirals, turning tapered rods, or laying down even bamboo textures a breeze. You get reliable torque for routing hardwood sign blanks, shaping soft aluminum brackets, or etching sharp marks on ceramic tiles without wandering tool paths.

✅ K11 style 100mm self centering jaws grip stock tight during heavy passes
✅ 22mm center bore accepts standard arbors for consistent roundness cuts
✅ Steady 20 to 1 gear reduction pairs with the built in stepper driver
✅ Manual tailstock sits at 70mm lift height to keep long workpieces straight

💡 How do I calculate perfect pulse division for a CNC fourth axis router upgrade?
Taking care of the math ahead of time saves you from ruined prototypes and wasted scrap on the shop floor, keeping your workflow nice and handy.
- Multiply your stepper microstep driver settings by the native coil rotations to get raw output counts
- Divide those raw counts by the exact 20 to 1 transfer ratio to match your desired inch or millimeter travel
- Type the resulting number straight into Mach3 or Weaver control panels before firing up your spindle
- Verify green and red wire mappings on the four lead plug to stop backwards feed when swapping materials
