HOW TO USE CHART
• Identify material on chart (solid, round, square, structural/tubing)
• Select tooth pitch from chart according to material size :
eg. 250mm solid round bar = 2/3 tooth – 1.4/2.0
TUBING AND STRUCTURALS
Multiply wall thickness by 3 times the wall thickness :
eg. 25mm x 3mm pipe : 9mm ie. 10/14 or 8/12 tooth
RUNNING-IN PROCEDURE
Feed rate should be reduced by 1/3 normal rate for first 450mm3 |
