Why Go Rigid?

During internal machining operations, the primary determinant impacting CNC turning centers or multi-task machines is frequently the rigidity of the boring bar, or rather, its lack thereof. It’s crucial to recognize that a carbide shank boasts nearly triple the rigidity compared to its conventional steel counterpart. While in the midst of machining, the steel shank tends to deflect or “push off,” especially when extended beyond a 3:1 length-to-diameter (L/D) ratio, or when engaging in threading, machining challenging materials, or facing interrupted cuts. This tendency often results in undesirable outcomes such as subpar surface finishes, dimensional variations, diminished tool lifespan, and decreased machine efficiency.

A rigid shank effectively mitigates vibration and has the potential to eradicate chatter altogether. Consequently, tool longevity is prolonged, necessitating fewer adjustments to offsets and insert changes. Enhanced rigidity affords the flexibility to fine-tune machining parameters, including cutting speeds and feeds, thereby optimizing cycle times. In a nutshell, your investment in a sturdy shank will continually yield returns, day in and day out. This includes reduced setup times, courtesy of chatter elimination, superior quality components, reduced scrap production, extended machining durations, heightened machine efficiency, and, ultimately, increased financial gains in your pocket at the close of each workday.
