We can provide a 4th axis system for all our CNC routers. The 4th axis system shown here is a stepper motor driven knife mounted instead of the spindle. The knife is driven and can be controlled such that the knife remains tangential to the cutting path.
We will soon have examples of where a 4th axis system is bolted to the bed of the machine for tuning type operations.
