MPCNC Needle Cutter

This is a needle cutter for an MPCNC Machine. This has 3mm holes in the face for 4 guide bearings. The brushless motor mounting pattern fits standard 16/19 self centering bolt patterns. The flywheel uses M3 screws and nuts to secure to a 3.17mm motor shaft. The holes in the face of the flywheel are 3mm that the threads of M3 screws will bite into. Both the flywheel face and the frame face have a 1mm extrusion to space the roller bearings. The Motor mount to face spacing accommodates 2212 brushless motors. The models are available in the Sketchup 3D warehouse for easy import and modification.

There is a balance between wire length, speed of the rotation and stiffness of the wire that you have to play with to get the best results. On the shorte
