BIG-PLUS OVERVIEW

FIT
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 • 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
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. THE BIG-PLUS SPINDLE SYSTEM IS AN ORIGINAL DEVELOPMENT OF BIG DAISHOWA SEIKI CO., LTD.

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 spindles have been adopted by licensed machine or 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.

BIG-PLUS OVERVIEW
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 With BIG-PLUS simultaneous contact, machining rigidity is greatly enhanced due to the larger contact diameter of the tool holder flange face. This larger face contact, combined with the taper contact, works together to resist deflection. With less deflection, greater machining accuracy and superior finish can be achieved.

DRIVE KEY FORM HSK Shanks according to Form A are designed to carry out torque transmission by the round shaped key-way at the end of the taper. Because of the importance of this round shaped geometry, BIG provides finishing of this feature after heat treatment.
IMPORTANT TOOL RETENTION FEATURE Internal clamping of HSK tools is defined by the location of highly concentrated forces from the machine tool. Accuracy and position of this form will affect the rigidity, repeatability and precision of tool holders. BIG provides finish machining of this area after heat treatment.

CK/CKB/CKN TOOLING SYSTEM OVERVIEW
CK, CKB & CKN VARIOUS CONNECTIONS — ONE SYSTEM Based on a cylindrical connection with radial locking screw, the world-famous modular precision tool system by BIG KAISER has continuously been improved over the years, and has adapted to customer’s needs and the increases in machine tool performance. Compatibility to existing tools has always been a requirement for newer designs. This means that all BIG KAISER connections are almost 100% compatible, and all the components are in stock.
Recess for the CKB Floating Cross-Bolt
CK Screw
CKB Floating Cross-Bolt
CKB CONNECTION: HIGHLY EFFICIENT AND EASY TO HANDLE The modular components are clamped with the lateral locking screw (CK-screw). The floating cross bolt is automatically centered in the trapezoid-shaped recesses in the mating part and ensures an absolutely uniform distribution of the torque forces. • Simple, efficient operation -no special equipment or tools needed • Maximum rigidity due to high preloading forces and large contact surfaces
• Precise cutting edge location even when using several adapters • High interchange accuracy, maximum radial change error is .0001"

CK/CKB/CKN TOOLING SYSTEM OVERVIEW
CKN CONNECTION: FOR LIGHTWEIGHT AND HIGH PERFORMANCE TOOLS Based on a 3-screw connection and a male pilot with 3 partial slits, the CKN connection is designed for lightweight and high performance tools. The main components for the program are double connector couplings made of steel and extension tubes made of aluminium. The high performance program for enhanced radial stiffness is entirely made of steel components.

Double Connector Coupling
Connector with Partial Slits
Extension Tube Aluminium
CKN CONNECTION: THE STRONGEST TOOL CONNECTION FOR LIGHTWEIGHT TOOLS The double connector coupling enables the use of aluminium extension tubes which result in a considerable weight reduction for larger tools. The torque transmission from the aluminium tube to the connector made of steel over three screws guarantees no reduction of cutting performance in comparison to tool combinations made of steel only.

SIMPLE, EASY HANDLING WITH SECURE CLAMPING 1. Place the exclusive Key Grip into the Weldon flat of the end mill shank.
2. Insert the end mill with the Key Grip in alignment with one of the three Key Grip grooves inside the milling chuck. 3. Rotate the end mill approximately 20º clockwise until the Key Grip stops securely against the stopper pin. 4. Finish clamping the tool until the clamping nut contacts the positive stop of the chuck body.
NON-PULLOUT MECHANISM The Key Grip engages in the groove of the chuck body to ensure no tool pullout.
COMPLETE FIT OF NUT AND BODY Tightening the nut achieves dual contact between the nut and body for rigidity close to that of an integral cutter.

HYDRAULIC CHUCK OVERVIEW
HYDRAULIC CHUCKS FOR SWISS-TYPE AUTOMATIC LATHES Hydraulic chuck system provides high accuracy and easy tool changes.
Improved Accuracy and Rigidity The lathe type hydraulic chuck was developed from decades of knowledge accumulated on milling machines. In addition to high accuracy and rigidity, the slim design helps avoid interference with adjacent tools.
Safe and Quick Operation The ability to change cutting tools with a single T-wrench drastically reduces the time required for tool changes. It also reduces the need to work in extremely limited spaces and improves operator safety.
±1μm Repeatability Even changing the tool, the repeatability at 4D is stable at ±1μm or less. In addition, the tightening is completed when the clamping screw hits the bottom, controlling tightening torque is not needed.
No Change in Tool Length Since the tool projection length does not change after the clamping, it is easy to control the tool projection length in the machine.
