BIG-PLUS TOOLING SYSTEM Simultaneous Taper & Flange Fit
BIG CAPTO TOOLING SYSTEM , ISO 26623-1 Polygon tapered dual-contact system (1:20 taper) where the face and taper of a machine spindle and tool holder are in contact. This modular tooling system strengthens the performance of milling and turning operations for MTCs. The trademark Capto is licensed from Sandvik Coromant.
HSK TOOLING SYSTEM Dual-contact system featuring a 1:10 taper in accordance to ISO & DIN standards. Since HSK is a hollow taper shank, the material plays a critical role for optimum performance. We use carefully selected high-grade alloy steels, and all critical features are finished after heat treatment.
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 • Elimination of Z-axial movement at high speeds

The BIG-PLUS spindle system is based on the most current available standards in ASME B5.50, JIS B6339 and DIN 69871.
Variety A wide variety of rotary tool holders such as the high-precision MEGA CHUCK series are available, as well as a modular turning tool system for MTCs. Excellent Repeatability The perfect fit of the polygon taper to drive spindle rotation ensures high repeatability. Excellent Runout Accuracy The combination of a self-centering 1:20 taper and the long taper edge ensures stable runout accuracy.

TOOLING SYSTEMS OVERVIEW
N/C LATHE TOOLING SYSTEM Improving The Efficiency of NC Lathes and Supporting Productivity Through Reliable Technology
CK/CKB TOOLING SYSTEM
Based on a cylindrical connection with radial locking screw, the world-famous modular precision tool system by 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 KAISER connections are almost 100% compatible, and all the components are in stock.
BIG DAISHOWA’s N/C Lathe Tooling series integrates high-precision holders and damping technologies to optimize turning, tapping, and centering tasks. Featuring innovations like the MEGA ER GRIP for repeatable accuracy and the SMART DAMPER BORING BAR for vibration control, these solutions support increased tool life, reduced cycle times, and improved surface finishes.

Simple and Positive Clamping Type F uses two clamping bolts that press the cartridge onto the basic holder. The torque is transmitted by an interlocking drive slot.
Secure and Rigid Clamping Type S Cartridges are mounted in the basic holder using a precision-ground pilot and two opposing 15º tapered radial screws. A slight socket offset ensures high face-to-face clamping force. A locating pin ensures precise positioning and torque transfer.

The Simplest Modular Boring Clamping System Secure Contact Using a Single Wrench The CK modular system is a simple method for securely and powerfully clamping multiple components with a single wrench. Moreover, even if the same boring head is repeatedly attached and removed, the cutting edge position does not vary by 2 microns (.00008"). This accurate clamping allows boring diameter setup to be done with a boring head only, increasing the machine utilization and drastically reducing labor.
