Modular Components

Our modular components are based on a cylindrical connection with radial locking screw. The BIG KAISER CK modular precision tool system 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 components are available from stock.

The World's Most Versatile Tooling System

BIG KAISER's modular CK system is fully compatible with all machine tool interfaces and allows the possibility to create tool assemblies specifically designed to satisfy your demands. Optional features such as anti-vibration, balance compensation, digital readout, and aluminum construction are all available from stock. The versatility of BIG KAISER tools leaves nothing to be desired.

Shanks

Shanks

BIG KAISER's tool shank program contains more than 150 different types of shanks, allowing you to pick the perfect shank for your machine tool spindles.

Reductions & Extensions

Reduction

Reductions & extensions make connections between different CK sizes within the system allowing for a large variety of tool combinations.

Solid Bars

Carbide Solid Bar

Carbide and heavy metal solid bars have a dense structure providing optimum rigidity and reducing vibrations in extremely long bores.

Damping Bars

Anti-Vibration Boring Bars, also known as Damping Bars, are tool shanks with integrated damping system for highly efficient deep hole finish boring.

ER Collet Adapters

ER Collet Adapter

ER Collet adapters enable the use of BIG KAISER boring heads in ER collet chucks for driven-tool applications in turning centers.

Coolant Inducers

Hi-Jet Holder

Hi-Jet Holder coolant inducers introduce coolant capabilities to machine tools without coolant-through spindles.

Frequently Asked Questions

What are some benefits of adding a modular cutting tool system to my operations?

Modular tooling allows for the possibility to create tool assemblies specifically designed to satisfy your demands. They add versatility not only to the tooling that can be used but also to the work that can be performed. That versatility, along with quick and easy changeouts, saves a lot of set-up and engineering time, delivering ROI faster than less modular tooling options.

What makes BIG DAISHOWA modular components unique?

BIG KAISER’s modular CK system is the most versatile in the world and all components are available from stock. The system works with all machine tool interfaces and compatibility with existing tools has always been a requirement. A simple lateral locking screw (CK-screw) is all that’s needed to secure the components together quickly and precisely. Here are a few other things that set our modular system apart:

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"
Double connector coupling made of steel and aluminum extensions for the transmission of high torques
Weight reductions up to 50% and equal cutting performance, compared to tool combinations made of steel
Reduced weight allows easier handling and eliminates manual tool change in many cases
Maximum rigidity of the tool connection due to high clamping force and expansion of the slotted tool connector
Vibration damping due to the use of different materials

How many modular components can be used in a boring setup?

Every boring assembly should be kept as short as possible. We recommend components should be limited to four or five, not including boring head insert holders.
