What Does It Mean to Be a Factory Authorized Big Plus Spindle Rebuilder?
The ability to rebuild a BIG PLUS spindle is a specialty few spindle repair companies possess. In fact, BIG PLUS spindle rebuilds are such a rare attribute that only nine operations in North America are licensed and authorized as “BIG PLUS spindle rebuilders.”
The reason so few operations possess these credentials is because working on BIG PLUS tooling requires special care and attention, in addition to extreme accuracy and precision.
But what is a BIG PLUS spindle, and what does it really mean to be a licensed and factory-authorized BIG PLUS spindle rebuilder? Let’s have a look:
BIG PLUS is a spindle system that provides dual contact between a spindle face and a flange face of BIG PLUS tooling. (For more information on spindle related terminology, click here). This unique tool holding technology increases surface contact with a tool holder, thereby maximizing rigidity and clamping pressure.
“There is a significant advantage in tool life, accuracy and cutting capability when compared to standard tool holders.”
In order for a shop to be granted a BIG PLUS license, it must demonstrate that special care and attention will be given to the tooling interface, drawbar, bearing journals and balance. A BIG PLUS spindle rebuilder must also ensure that they provide the extreme accuracy required of all factory-authorized BIG PLUS rebuilders.
