Lovejoy Tool Co. Inc. offers PCD chip control geometry inserts. The inserts break chips, increase production and improve employee safety by eliminating the removal of a nest of stringy chips when machining aluminum and copper alloys, according to the company. They are used in turning and boring, especially on screw machines. PCD Chip Control Geometry inserts are targeted to the customer that requires a chipbreaker at the actual cuttingpoint. Conventional flat face PCD inserts in continuous contact machining, like boring or turning, can experience hard to handle continuous chips, which can cause lost production time or result in poor surface finish. Lovejoy's chip control geometries put the chip control at the cutting point resulting in better control with a short chip. The inserts are offered in two chip breaker geometries: for finishing or general-purpose machining. The inserts reportedly produce less cutting pressures and heat expansion of the parts being machined, allowing a 20 to 30 percent increase in tool life and finer surface finishes.
