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.

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

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.

HSK OVERVIEW

HSK TOOLING SYSTEM ISO 12164/DIN 69893/ASME B5.62

Selected materials and strict control of dimensional accuracy for the optimum quality. Wide range of standard holders to meet all production requirements.

AVAILABLE IN HSK TYPE A/E/F HSK SIZES 25/32/40/50/63/80/100/125

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 HSK40 and smaller where the cross section of shank taper is very thin.

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.

NON-SLIP MECHANISM The Key Grip maintains contact with the stopper pin to prevent any slip under high torque.
