Columbus McKinnon Engineered Products supplies Pfaff-silberblau motion technology for automated pipe-end finishing
With linear actuators ALS/R and MERKUR screw jacks of the Pfaff-silberblau brand, Columbus McKinnon Engineered Products ensures outstanding performance when deburring pipe ends. The user, the company Sema Systemtechnik, uses the reliable Pfaff-silberblau components to make its highly productive pipe-end finishing machines. The machines process up to six pipes per second in sizes ranging from 1/4 up to 3 inches from steel and stainless steel through to galvanised aluminium. The MERKUR worm gear screw jacks and ALS/R electromechanical screw rams combine to ensure the automated and precise positioning of the sometimes bulky workpieces.

Automated processes

A processing cycle in the pipe-end finishing section comprises all the processes from the separation and the feeding to the simultaneous external and internal deburring, two-sided thread cutting and integrated threaded socket fitting through to the ejection of the pipe. These processes are geared to high productivity and short cycle times - this also applies to the conveyor technology. The MERKUR worm gear screw jacks from Pfaff-silberblau automatically raise and manoeuvre a drilling machine table that holds the pipes into position. The movement is executed by a self-locking trapezoidal screw with a 25 kN lifting capacity.

Positioning the pipes

The Pfaff-silberblau electromechanical screw ram ALS/R size 10 is used for positioning the workpieces ready for deburring. With its rotating ball screw, this linear actuator positions the pipes vertically at high speed and precisely with a force of 12.5 kN for a 300 mm stroke with speeds of up to 10 m/min (167 mm/s), such that the tool can extend immediately and commence processing.

Sema is a leading international manufacturer of machines and systems for the semis industry and packaging technology. The processing machines from this manufacturer are easy to maintain and to operate. Thanks to the components from Columbus McKinnon Engineered Products they deliver outstanding performance and versatility for finishing pipes with a wide range of lengths diameters.
