Close The Performance Gap with BIG-PLUS®
BIG-PLUS® is a spindle system that provides dual contact between the spindle face and the flange face of BIG-PLUS® tooling. Simply by switching holders, you can greatly increase tool rigidity, reduce runout and add significant productivity to your machining applications. BIG-PLUS® holders and spindles are manufactured to micron level specifications.
The unique tool holding technology increases surface contact with the tool holder, maximizing rigidity and clamping pressure. There is a significant advantage in tool life, accuracy and cutting capability when compared to standard tool holders. Because of the unique design, the system allows complete interchangeability between existing tooling and spindle systems. No shim kits or spindle face qualification is necessary.
Whether you requested it or not, your machine may have a BIG-PLUS® spindle. BIG Daishowa developed one of the world's most adopted OEM specifications in BT and CAT spindle design. As a result, BIG-PLUS® spindles are often standard equipment on machines ordered with a CAT or BT interface. While this spindle works with all CAT or BT holders, there is a distinct performance advantage when used with BIG-PLUS® tool holders.
The BIG-PLUS® spindle system is offered by many of the world's leading manufacturers of machining centers. Some of the machine and spindle builders who have produced BIG-PLUS® spindles are as follows:
