Flexible abrasive stars for tubing
- April 10, 2016
PFERD has developed a new product in its line of flexible abrasive stars for work on hard-to-reach inner surfaces of bores and pipes.
PoliStar-Tube is a multi-stage tubing system. To prevent corrosion on stainless steel pipes, the new abrasive star is manufactured using stainless steel rivets exclusively.
The flexible abrasive stars are well suited for small diameter bores and pipes in the ¼ - 1 ½ in. diameter 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. It 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.
This multi-stage internal fine-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.
