Cheater bars are appropriately named, especially when it comes to tightening tool holders. We see the common pipes that are often added to the end of wrenches to achieve more torque in customers’ shops all the time. And while these makeshift wrenches may make tightening or loosening holders easier, the damage they can cause is often overlooked.
As cutting tool manufacturers increase the recommended operating conditions for their products, users achieve the desired result: shorter cycle times on existing machine tools.
When that inevitable job arises that requires higher RPM output, operators are left with the choice of replacing the machine altogether to gain higher productivity, or looking into an attachment, like a spindle speeder, to close the RPM gap.
There are three particularly sensitive areas of the tool holder assembly that can experience process-affecting wear and tear and cause a cycle to change.
