Overview

This document provides detailed technical specifications, ordering information, and dimensional data for various tool holders and live tools compatible with OKUMA machine models, including LB 2000 to LB 4000 EX series, LT series, and VDI 40 tool holders. The content covers multiple tool styles, mounting types, coolant options, gear ratios, torque ratings, and dimensional parameters.

1. Tool Holder Types and Styles

• Square Locking Drive (Radial): Used for main, opposed, and overhead spindles with square cross-section locking (e.g., 25x25 mm).
• Turning Tool Holder (Axial): Designed for axial mounting on main, opposed, and overhead spindles.
• Boring Bar Holders: Available in single and double configurations, some with internal coolant (IK/IC) options.
• Swiveling Holders: Provide angular adjustment (e.g., ±98° to ±105°) with ER collet chucks for flexible tool positioning.
• Static Holders and Collet Chucks: Including BENZ Solidfix® and CAPTO™ modular quick-change systems for efficient tool changes.

2. Technical Specifications

Each tool holder is specified with the following key parameters:

• Order Number (Bestell-Nr.): Unique identifier for ordering.
• Tool Style (Ausführung): Axial, radial, swiveling, static, etc.
• Tool Holder Type (Aufnahme): ER collet size (e.g., ER16, ER25, ER32, ER40), square locking, boring bar diameter.
• Maximum Speed (n [min-1]): Ranges typically from 4,500 to 8,000 rpm depending on tool type.
• Gear Ratio (Übersetzung): Usually 1:1 or close variants (e.g., 1:0.82, 1:0.88, 1:2).
• Torque (T [Nm]): Torque capacity varies from 30 Nm to 150 Nm depending on model.
• Coolant Options: External coolant (EK/EC) and internal coolant (IK/IC) availability indicated.
• Maximum Pressure (pmax [bar]): Typically 40 to 100 bar for coolant supply.
• Dimensions: Detailed dimensions including diameters (D, D1), lengths (L, L1, L3, L4), and other relevant measurements for mounting and tool length.

3. Compatibility and Machine Models

The tool holders and live tools are designed for compatibility with various OKUMA machine models:

• LB 2000 EX-M, EX-MW, EX-MY series
• LB 2500 EX-M, EX-MW
• LB 3000 EX-M, EX-MW, EX-MY, EX-MYW
• LB 4000 EX-M
• LT 15 M, LT 300 M, Mac Turn 250-2S, Mac Turn 350-2S
• VDI 40 tool holders for LB, LR, LU series

4. Additional Notes and Recommendations

• Accessories referenced (starting from page 103) are not included with the tool holders and must be ordered separately.
• Technical data and dimensions are subject to change without notice.
• Right-hand (R) and left-hand (L) versions are available for certain tool holders.
• Dimension A* indicates the maximum length including the clamping nut.
• Modular quick-change systems such as BENZ Solidfix® and CAPTO™ are supported for efficient tool changes.
