PFERD
POLISTAR-TUBE
POLISTAR-TUBE is made up of several layers of grinding stars riveted together. POLISTAR-TUBE grinding stars are used especially for working the inside surfaces of pipes and pipe bends. The grinding stars may be used with ¼” shank drive arbors or with PFERD’s flexible shafts.
POLISTAR-TUBE is ideal for:
- step-by-step cleaning and finishing of inner surfaces and pipe bends
- rounding off pipe ends and deburring bore holes
- use in straight pipes and deep bore holes. (With this application the stars are used with drive arbors.)
Advantages
- Extremely flexible
- Very high-quality surface finishes up to Ra 0.2 µm can be achieved.
Recommendation for Use
The following pipe inner diameters can be worked using different diameters:
- 2” diameter stars for inner pipe dia. 1-3/8” - 1-5/8”
- 2-1/4” diameter stars for inner pipe dia. 1-5/8” - 1-3/4”
- 2-3/4” diameter stars for inner pipe dia. 1-3/4” - 2”
- 3-1/8” diameter stars for inner pipe dia. 2” - 2-1/4”
- 3-1/2” diameter stars for inner pipe dia. 2-1/4” - 2-3/8”
- 4” diameter stars for inner pipe dia. 2-3/8” - 2-5/8”
The different grit sizes can be used to achieve the following roughness values:
- Grit size 60 = 1.0 - 1.3 µm Ra
- Grit size 120 = 0.6 - 1.0 µm Ra
- Grit size 180 = 0.4 - 0.6 µm Ra
- Grit size 240 = 0.3 - 0.4 µm Ra
- Grit size 320 = 0.2 - 0.3 µm Ra
To prevent corrosion forming on stainless steel (INOX) pipes, POLISTAR-TUBE is made using stainless steel rivets.
