Industry Issue: No commercially available Polycrystalline Diamond (PCD) solution that combines the wear-resistance of a PCD tool with the feed rates and finish quality of a solid carbide tool.
PCD tooling feed rates are typically 50% lower than solid carbide tooling due to the lack of cutting geometry and the difficulty of producing a finished edge.
Goal: Develop a PCD tool the combines the long life of diamond and feeds as fast as a solid-carbide roughing tool. The tool must also produce a finished edge equal to a solid carbide compression tool.
The tool must be a commercially viable solution to the woodworking industry.
Onsrud Cutter’s QuadraMax cutter is the first ever PCD tool to combine roughing, chipbreaking, finishing and compression geometries in one tool.
The chipbreaker edges further contribute
to increased feed rates as the chip size is reduced allowing for ease of chip removal from the cutting path.
The rougher edge is key to the design of the tool as the scalloped cutting edges break up cutting forces allowing
increased feed rates and extends the life of the cutting edge over traditional PCD tools.
The finisher geometry generated as a
result of the offset chipbreakers produces
a finished surface required by today’s
demanding CNC operator.
The up and down/compression geometry
on all flutes produces a chip-free edge on
both top and bottom surfaces which is
especially important on laminated wood
