What advantages can YOU reasonably expect to achieve when using SPIREX Broaches?
Elimination of chatter or harmonic vibrations during the broaching cycle
This is achieved through the innovative design of a spiral tooth form similar to a course tapered thread on a wood screw. This type of tooth form provides “consistent, tooth engagement” through the entire cut. As a result, the broaching forces are consistent throughout the broach cycle, thus eliminating the “chatter” so common to conventional broaches. The spiral tooth form also acts as a “continuous reinforcement rib” creating a stronger stiffer tool that is less likely to spring or warp under broaching pressure.
Improved surface finish
Improved surface finish is primarily achieved through the “spiral shearing action” of the tooth’s cutting edge. The helix angle shears the chips off to the side, and it’s this sliding action that improves the surface finish. In addition, the above-mentioned elimination of broach “chatter” significantly enhances the part finish.
Increased production between sharpening
Increased production is achieved through the elimination of micro chipping of the cutting edge caused by chatter. This significantly extends the longevity between sharpening. Another major contributing factor is the continuous flow of coolant through the spiral “open” tooth gullets. This enhances the lubrication at the cutting edge and reduces heat build up in both the part and tool.
Most of all, you can expect to receive a greater return on investment
This improvement is achieved through an increase of parts broached between sharpening. There are also hidden benefits that will improve your ROI such as, less “wear and tear” on your broaching machine, due to the elimination of “chatter”. This translates to a reduction of “costly maintenance” and “down time”.
