Special Formed PCD Insert with Necking Edge
PCD Brazed Cutting Edge with Necking Edge
· The use of three formed inserts enables one-pass finishing even on pre-cast hole work with large variations in machining allowance. · The introduction of a parallel adjustment mechanism maintains high squareness accuracy even when diameter height is adjusted. · Light-weight aluminum alloy body enables usage on small machining center with weight limitations.
· By brazing the PCD cutting edges directly to the body, the number of effective cutting edges is increased from 3 to 6, thus achieving higher machining efficiency.
