Flexible Abrasive Stars aid small diameter inner deburring.

Press Release Summary:

POLISTAR flexible abrasive stars are designed for work on hard-to-reach inner surfaces of small-diameter bores and pipes in ¼–1 ½ in. dia range, and POLISTAR-TUBE multi-stage tubing system, manufactured using only stainless steel rivets, prevents corrosion on stainless steel pipes. Available in range of diameters and grit sizes, products can be stacked in several layers and aligned at offset from one another for optimal effect. Multi-stage internal fin-grinding system optimizes efficacy.

POLISTAR and POLISTAR-TUBE from PFERD Bring New Levels of Ease and Efficiency to a Range of Small Diameter Tube and Pipe Inner Deburring Applications

Cleaning, fine grinding and light deburring of hard to reach small diameter bore and pipe interiors are now more efficient

Milwaukee, WI – POLISTAR, the line of flexible abrasive stars from PFERD INC. that has been developed for work on the hard-to-reach inner surfaces of bores and pipes, has just gotten even more effective with the introduction of POLISTAR-TUBE. POLISTAR-TUBE is a multi-stage tubing system that highlights the effectiveness of POLISTAR on even more hard to reach bore and pipe interiors. To prevent corrosion on stainless steel pipes, POLISTAR-TUBE is manufactured using stainless steel rivets exclusively.

POLISTAR flexible abrasive stars are particularly well suited for small diameter bores and pipes in the ¼ - 1 ½” dia. range, performing an array of tasks such a cleaning, fine grinding and very fine grinding of bores; removal of heat discoloration in stainless steel after welding; inlet and outlet radiusing of bores; light deburring; and deburring in cross bores. POLISTAR can be stacked in several layers, aligned at an offset from one another so that the abrasive has the optimal effect. It reduces setup times significantly as pads can be changed without removing the arbor from the collet.

POLISTAR-TUBE brings POLISTAR inherent flexibility to the next level. This multi-stage internal fin-grinding system, used with the appropriate flexible shaft and motor drive, allows the POLISTAR concept to be effective on the most difficult-to-access inner surfaces of pipes, pipe bends and deep bores. Available in a range of diameters and grit sizes, POLISTAR-TUBE is ideal for applications from rough cleaning and deburring up to very fine grinding, with surface finishes up to 8µ” Ra.

In terms of improving working comfort levels, always a key consideration with PFERD, POLISTAR and POLISTAR-TUBE reduce vibration and noise levels during these operations, in a cost effective manner.

PFERD INC. is the U.S. subsidiary of August Rüggeberg GmbH & Co. of Marienheide, Germany.  As a global manufacturer and distributor of abrasives, brushes and power tools, PFERD offers a comprehensive line of products and services for metal cutting and surface conditioning.  With over 200 years of experience in developing innovative products that optimize productivity, achieve economic efficiencies and improve operator health and safety –customers around the world TRUST BLUE.
