FIT

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 • Improvement of ATC repeatability • Elimination of Z-axial movement at high speeds • Improved roundness of boring operations

SPACE

BASIC CONCEPT The BIG-PLUS Spindle System is based on the most current available standards in ASME B5.50, JIS B6339 and DIN 69871. A conventional steep taper tool holder is supported on a reference diameter called the gage line. On the contrary, a BIG-PLUS tool holder is supported on the flange face, which brings remarkable improvement to rigidity.

PERFECT INTERCHANGEABILITY BIG-PLUS tool holders can be used on existing standard machine spindles. Existing standard tool holders can also be used on BIG-PLUS spindles. In this case, however, simultaneous contact cannot be attained. Although other simultaneous contact systems require exclusive new accessories, BIG-PLUS tooling uses existing accessories such as a tool presetter and tool holder fixture as it is based on a conventional steep taper shank. Further, it is not necessary to modify tool magazines and ATC devices of existing machines.

BIG-PLUS OVERVIEW

THE BIG-PLUS SPINDLE SYSTEM IS AN ORIGINAL DEVELOPMENT OF BIG DAISHOWA SEIKI CO., LTD. BIG-PLUS spindles have been adopted by licensed machine and spindle builders around the world under strictly controlled dimensions using BIG’s master gage. In order to protect the spindle or prevent possible accident, only use tool holders with the BIG-PLUS trademark. IMPROVEMENT OF ATC REPEATABILITY The BIG-PLUS Spindle System ensures the highest precision location of the tool holder in the spindle when using the ATC for loading tools as a result of the dual contact, which precisely positions the tool holder within 1 micron.

MINIMIZED DEFLECTION FOR MAXIMUM MACHINING ACCURACY & SUPERIOR FINISH BIG-PLUS simultaneous contact enhances machining rigidity with the larger contact diameter of the tool holder flange face, reducing deflection and improving accuracy and finish.

STRICT GAGE CONTROL BIG-PLUS spindles produced by the licensed machine and spindle builders are strictly controlled in dimensions by the original BIG master gage. Only BIG-PLUS trademarked tool holders can achieve the optimal performance fully and safely.

• Wrench must be ordered separately • Please note that the practical spindle speed may be considerably influenced by the machine rigidity and tool balance, when using, slowly ramp up to the appropriate speed starting from slow speeds • MEGA16DS requires the hex socket head screw (M8) for axial adjustment, however, please contact us if using for center-through applications • “H” indicates the adjustment length with an adjusting screw • DS types have jet-through coolant supply, thus tools with holes cannot be used

• Wrench and axial adjusting screw must be ordered separately • When using center-through coolant: - Set screw with sealing compound applied (standard accessory) should be used to plug an air bleed hole

- Oil hole type should be chosen when straight collet is required • “H” indicates the adjustment length with an adjusting screw • When using center-through coolant, insert tool shank into E 1 or more • HMC16S requires the hex socket head screw (M8) for axial adjustment, however, please contact us if using for center-through applications; models marked v

• “H” indicates the adjustment length with an adjusting screw • Adjusting screws cannot be used with models marked v • Straight collets cannot be used with models marked u • In case the projection length needs to be adjusted from the shank side, add the letter “W” to adjusting screw model number for hexagon sockets on both sides (ex: HDA6-05020W), adjusting screw with l indication is not available in W type

Use only cutting tools that have a shank tolerance of h6 (see table pg. 26). Do not use with cutting tools made with a flat on the shank (ie: Weldon type shank). Roughing end mills are not recommended for use with hydraulic chucks. Do not tighten the clamping screw without first inserting a cutting tool into the tool holder. Always insert the cutting tool into the hydraulic tool holder beyond min. clamping length “E”.
