The tolerance of honed id tubing
Honed ID Tubing also called honed cylinder tube or honed cylinder barrel.The honing process involves using abrasive polishing stones and abrasive paper to remove small amounts of material, to produce extremely precise ID dimensions and improved finishes. Honed tubing is ready to use for hydraulic cylinder applications without further ID processing. Honed ID cylinder tube processing: Raw Materia - Acid cleaning - Parkerizing - Cold-drawn - stress relieving - leveling - Saw off reject parts - Honing - Anti oil coating - Packing.
