All Cannon Bar Works chain saw bars are made from high grade, formulated, cold rolled and annealed steel. From the raw steel, each bar is laser cut. Once the steel is cut, it is heat treated and quenched. Then, the hardened bars are carefully straightened and surface ground to the ideal thickness. Surface ground bars are then milled with CNC milling machines. Different milling patterns are cut. Once a bar is milled it is then given the precision ground groove. Every bar has a true and centered groove that is accurate to within .002″ of the desired gauge. Next, is the rail hardening, the bar rails are hardened to 5 points more than the tie straps on most models and brands of chain. Bar lengths are also pressed at the heel in order to reduce vibration and prevent premature cracking from vibration. Bars are then put through a stress relieving system in order to expel tension that builds up in the bars through all of the different processes. Cannon applies gunmetal finish to most of the bars. Some longer lengths and specialty bars still have Cannon’s classic matte black painted finish.
