A new traveling planetary cutter (M-TPC) from Conair (Cranberry Township, PA), which had its debut at PLASTEC East this week in New York, NY, features a fully-programmable, servo-driven cutting head that cuts small-diameter medical plastic tubing so precisely that the need for secondary, off-line finishing operations are virtually eliminated. “The elimination of secondary processing can save customers as much as 60%,” Bob Yore, Product Manager, Downstream Extrusion, told PlasticsToday from the show floor.
Unlike other cutters that can leave behind particulates, the M-TPC cleanly splits apart the tubing via displacement, without any material loss. The planetary knife spins around the circumference of tubing, never blocking airflow through the center of the tube. Consequently, tube sizing and ovality are not affected. The programmable cutting head enables complete and precise control of cutter speed (surface speed), rate of cutter penetration (feed speed) and final depth of the cut. The system is suitable for tubing with outer diameters measuring between 0.080 and 1 inch.
The equipment’s three-axis servo movement is patented. “We filed the patent application just one week before bringing the M-TPC here to the show,” said Yore.
