EWE Series: Digital fine boring heads with absolute setting accuracy, designed for ultra-precise operations with high spindle speeds.
EWB Series: Features automatic precision balancing and variable length adjustment for vibration-free boring.

Smart Damper System

Incorporates a dynamic damping system to eliminate vibration, enhancing productivity and surface finish quality, available in various configurations for different applications.

Inserts and Cutting Data

BIG KAISER develops inserts that meet high demands for performance and precision, with cutting data tables available for optimal insert selection.

Angle Heads

Designed to eliminate multiple set-ups, combining vertical, horizontal, and angular operations to save time and improve accuracy, featuring compact design and innovative sealing methods.

Air Turbine Spindles

High-speed spindles improve drilling and end-milling performance by increasing spindle speed, suitable for micro-machining on standard machining centers.

Spindle and Machining Accuracy
The document emphasizes the importance of dynamic runout accuracy in micro-machining, highlighting a system that measures spindle movement during high-speed rotation to improve machining accuracy, surface finish, and tool life. Three types of air turbine spindles are mentioned: RBX5, RBX7, and RBX12, with minimal thermal displacement to prevent spindle expansion.

Air Turbine Spindle Features
The air turbine drive prevents thermal expansion, essential for high accuracy, with reinforced gear driving systems and increased rigidity through larger diameter bodies and double angular contact bearings.

Application Range
A table details the application range for different spindle types (RBX5, RBX7, RBX12) across various drill and end mill diameters, indicating optimal and acceptable uses.

Measuring Tools
Precision measuring tools like the Point Master Pro Series and Base Master Series are introduced for determining workpiece offsets and tool lengths, along with the Dyna Test and Level Master tools for machine tool maintenance and leveling.

Cutting Tools
The Fullcut Mill is highlighted for its sharpness and toughness, offering high precision comparable to solid endmills. The Speed Finisher is discussed for improved surface finish, and the C-Cutter Mini for high feed rates with a compact design.

Accessories
Various accessories are mentioned, such as the Center Boy for centering and chamfering, and the Torque Fit for controlling tightening torque in tool assembly.
