Many machine shops lack objective criteria for making toolholder purchasing decisions & most are made by price alone. However they can improve runout significantly by using the right toolholders.
Chattering and deflection have always been the bane of machinists’ existence, so much so that the sight of a long and slender tool holder will immediately cause goosebumps. If you understand why a long tool holder behaves the way it does, you’ll know that there are ways to fight back against this bending.
After years of close observation and collaboration with manufacturing companies of all sizes, BIG DAISHOWA Seiki engineers have learned how the choice of tool holders affects production costs on the shop floor.
If you purchase cheap dual contact tooling after being told by a supplier that it will work just as good as the original you risk unsatisfactory performance.
