BIG-PLUS DUAL CONTACT The World's Most Rigid Dual Contact Spindle System

BIG-PLUS was developed to unlock the full potential of spindle rigidity. Both the spindle and tool holder are manufactured to precise specifications, allowing the gap between the spindle face and flange to close simultaneously. This ensures consistent, reliable dual contact every time a BIG-PLUS tool holder is loaded into a BIG-PLUS spindle, delivering repeatable performance. In addition, BIG-PLUS maintains full compatibility with standard tooling, allowing conventional holders to be used in BIG-PLUS spindles when needed and vice versa. The BIG-PLUS Spindle System is an Original Development of BIG DAISHOWA Seiki Co., Ltd.

SIMULTANEOUS TAPER & FLANGE FIT BIG-PLUS surpasses all other spindle concepts while offering interchangeability with existing machines and tool holders. • Improved surface finish & dimensional accuracy • Extended tool life • Prevention of fretting corrosion caused by heavy cutting • Improvement of ATC repeatability • Elimination of Z-axial movement at high speeds • Improved roundness of boring operations

BIG-PLUS

CONVENTIONAL

Basic Concept Conventional steep taper holders are supported at the gage line diameter, while BIG-PLUS holders also contact the flange face—significantly increasing rigidity.

BENEFITS OF BIG-PLUS

High Spindle Speeds At high speeds, spindle expansion from heat and centrifugal force can pull standard tool holders inward. BIG-PLUS holders prevent this by contacting the spindle face, minimizing Z-axis projection variation (variation due to heat exists).

Perfect Interchangeability BIG-PLUS tool holders work with standard spindles, and standard holders can be used in BIG-PLUS spindles (without dual contact). Unlike other systems, BIG-PLUS requires no new accessories or machine modifications, as it’s based on a conventional steep taper.
