About This Product
The drawbar in the spindle pulls the arbor in firmly, the machine brackets support it through the bearing bushes, and spacers set each cutter where it is needed. Shorter arbors are advised wherever the brackets allow, and the end thread should run against spindle rotation – LH threads for clockwise (RH) rotation, RH threads for anticlockwise (LH) – so the arbor does not loosen. To order, state the taper, length and threading. Colleges and TVET centres in Paraguay, Burkina Faso, Bangladesh, Malaysia, Solomon Islands and Mali can source the Long Milling Arbors from Educational Lab Equipments.
