Finishing router cutter downcut with right-hand Z3

Machines:
Nesting and CNC overhead routing machines.

Materials:
Softwood, hardwood and wood-based panels.

Applications:
Sizing, plunging and grooving.

Technical information:
Solid carbide bit with negative helix designed for CNC routing for high feed rate applications.
• Suitable for: sizing, ramp plunging and grooving with a perfect finish.
• Downcut helix, helps the clamping of the workpiece, downward chip removal for the best finish on the upper side of the panel.

Working parameters
To find suggested feed speeds see the tables below and apply the following correction factors. Materials:
Hardwood: 0,9 MDF, Chipboard: 1,1 Depth of cut:
From 1 x D to 2 x D : 0,75 From 2 x D to 3 x D : 0,5 Over 3 x D : 0,4
Rotation speed:
Suggested speeds are proportional to RPM. Examples:
Factor for 12.000 RPM: 12.000/18.000 = 0,66
Factor for 24.000 RPM: 24.000/18.000 =1,33
To maximise the tool life, always set the maximum speed that delivers the needed quality of cut.
Suggested speeds for softwood: 18.000 RPM. Depth of cut equal to cutting diameter.
