For accurate nondestructive tests on tube and bar stock, a calibration procedure is used to establish an acceptable quality level for a given lot of material. An artificial defect on a sample of the material to be inspected is machined or drilled. This defect has to be carefully calculated and machined to correspond to a minimum acceptable quality level.
To cut precision EC calibration notches in pipe and bar stock:
Saw operates dry; do not use cutting oil.
• Strap MicroBite securely to pipe or bar stock measuring 1” to 24” in outer diameter.
• Zero blade against pipe surface.
• Adjust blade speed knob using knob.
• With blade spinning, turn depth screw until integral micrometer shows desired depth.
• Advance blade with hand crank.
