The new planetary cutters from Conair process PVC and polyolefin pipes in diameters ranging from 0.630 to 24.9 inches.

New PipeMaster planetary cutters from Conair are designed to produce continuous, distortion-free cuts in extruded PVC and polyolefin pipe in diameters from 0.630 to 24.9 inches and at line speeds reaching 82 feet per minute. The cutters are available in six sizes; the smaller MDT series cutters handle pipes up to 4.3 inches with the larger MTT series handling the rest. 

All of the PipeMaster cutters are equipped with a servo-driven, traveling cutting carriage whose speed is synchronized with the line speed of the master extrusion control. The traveling carriage carries an automatic clamping system and planetary cutting head. As extruded pipe enters the machine, the automatic clamping system locks the cutting head onto the moving pipe and the planetary cutting head rotates a cutting disk rapidly around the pipe to complete the cut. Finished pipes then move down the cutter’s support tray for off-loading.

Users can set up and operate the cutter with a 7-inch color touchscreen HMI that makes it simple to enter and manage speed controls, alarm capabilities, and new and existing production recipes. It also manages communications with upstream extruder controls or downstream measuring equipment. Other key equipment positioning and adjustments are motorized for operator ease and convenience. The cutter also provides full guarding for operator safety, including safety tunnels and interlocks on all opening doors.  

“The MDT and MTT planetary cutters combine rugged reliability, cost-efficient performance, and simple, well-engineered controls,” said Ernie Preiato, Conair Vice President, Extrusion. “They’re part of a larger PipeMaster line that enables pipe production of up to 24.9 in. (630 mm) in size, backed by Conair global service and support.” 

Preiato adds that planetary cutting technology is preferred, especially for larger diameter extruded plastic pipes, because it ensures continuous, square, distortion-free cuts. Since the process creates no chips or waste, pipe yields are optimized and no secondary cleaning or cutting operations are required.
