BIG-PLUS Improved stability with BIG-PLUS

​BIG-PLUS® spindle system* is adopted by a large number of machining centres and many machine-tool builders have recognized this system for its excellent performance.  BIG-PLUS is a dual-contact system that provides  taper and flange contact when tool holders are clamped into the spindle.

The BIG-PLUS  solid holder assortment consists of  Machine interface adaptor, Face mill, Combi Weldon/ISO9766 holders , CoroChuck™ 930 and ER collet chucks. Choose solid holders when there is a small need for flexibility in high batch production.
