BIG-PLUS surpasses all other spindle concepts while offering interchangeability with existing machines and toolholders. Improved surface finish & dimensional accuracy Extended tool life Elimination of Z-axial movement at high speeds Prevention of fretting corrosion caused by heavy cutting Improved roundness of boring operation Basic Concept A conventional steep taper toolholder is supported on a reference diameter called the gauge face. On the contrary, a BIG-PLUS toolholder is supported on the flange face, which brings remarkable improvement to rigidity. INCREASED CONTACT DIAMETER (Example...

Improvement of ATC Repeatability The BIG-PLUS System assures the highest precision location of the toolholder in the spindle when using the ATC for loading tools, as a result of the dual contact which precisely positions the toolholder within 1 micron. TEST BAR PULLING FORCE (ZERO RUNOUT) 800kg Taper Contact (Conventional) Dual Contact (BIG-PLUS) Note: Horizontal machine (4 years old) was used for the test. Minimized Deflection For Maximum Machining Accuracy & Superior Finish With BIG-PLUS simultaneous contact, machining rigidity is greatly enhanced due to the larger contact diameter of the...

Selected materials and strict control of dimensional accuracy for the optimum quality. Wide range of standard holders to meet all production requirements. HSK form A HSK form E HSK form F Premium Material Selection Since HSK is a hollow taper shank, the material has a critical role for optimum performance. BIG uses carefully selected high grade alloy steels. Particularly, BIG uses die steel materials for HSK 40 and smaller where the cross section of shank taper is very thin. HSK Shanks according to Form A are designed to carry out torque transmission by the round shaped key-way at the end...
