BIG-PLUS Spindle System is a standard product of BIG Daishowa Seiki Co., Ltd.
Although, holders of other companies with ground end faces exist on the market, please be aware that the dual contact is not possible on those systems.

The BIG-PLUS Spindle System offers simultaneous dual contact between the machine spindle face and toolholder flange face, as well as the machine spindle taper and long toolholder taper shank. This system is based on the most currently available standards for JIS-BT, DIN69871 and CAT-V Flange tooling.

AXIAL MOVEMENT IS IMPORTANT FOR FACE CONTACT

The numerous merits of BIG-PLUS:

  • Rigidity improvement thanks to an increased fit diameter
  • Drastic improvement of the ATC repeatability
  • Prevention of displacement in the Z-axis
  • Improvement of the life of the cutting tool
  • Prevention of fretting corrosion
  • Improvement and stability of the machining accuracy and machined surface

ULTRA HIGH TOLERANCE GAUGE CONTROLS GUARANTEE FULL INTERCHANGEABILITY

No, there is no problem. The BIG-PLUS Spindle System strictly dictates the dimensions of the spindle face of a machine and the flange face of a toolholder. These dimensions are controlled by exclusive high tolerance gauges and measuring equipment, so dual contact of the taper and face is guaranteed. Full interchangeability therefore exists between all BIG-PLUS machine spindles and BIG-PLUS toolholders.

Adopted by the major national and international machine tools and spindle manufacturers. Numerous results that attest the "True" dual contact system
