Technical Summary of Modular Fine Machining Toolholders

1. Product Types and Descriptions

The document details various types of high-precision toolholders designed for fine machining applications, including:

• Hydraulic Toolholders - Provide highly accurate radial and axial alignment with coolant flow maintained without loss or disruption via an intermediate tube.
• High Power Collet Chucks (HPTC) - Designed for high clamping torque with precise radial and axial alignment, also featuring coolant flow through an intermediate tube.
• Shrink Fit Chucks - Offer high precision with axial damping screws for optimal concentricity, maintaining coolant flow integrity through an intermediate tube.

2. Key Specifications and Features

• Balancing Quality: G6.3 at 15,000 revolutions per minute (rpm).
• Tool Shank Tolerance: Designed for h6 tolerance.
• Cooling System: Uses an intermediate tube to ensure coolant delivery without loss or flow disruption.
• Alignment: High precision radial and axial alignment suitable for adaptors or machine spindles.
• Axial Damping: Present in shrink fit chucks to optimize concentricity.

3. Delivery Contents

• Adjustment screw for conventional cooling.
• Angular alignment set.
• Four clamping screws.
• Hexagon chuck key (for some models).
• Note: Intermediate tube must be ordered separately.

4. Options and Accessories

• Intermediate tubes are optional and must be ordered separately.
• Reduction bushes are available for other clamping diameters (referenced on page 250).
• Accessories such as conventional and notch-free nuts, and corresponding wrenches are available (referenced on page 286).

5. Availability and Dimensions

The toolholders come in various sizes with specific dimensions (D, D1, D2, L) and corresponding product codes. Examples include:

• Hydraulic Toolholders: Diameters ranging from 8 to 20 mm with lengths from 32 to 82.5 mm.
• High Power Collet Chucks: Diameter 16 mm, length 40 mm.
• Shrink Fit Chucks: Diameters from 6 to 25 mm with lengths from 21 to 44 mm.

6. Multilingual Presentation

All product descriptions, specifications, delivery contents, and options are provided in English, Spanish, and German to accommodate international users.

7. Critical Notes and Best Practices

• Ensure ordering of intermediate tubes separately to maintain coolant flow integrity.
• Use reduction bushes for tool shank diameters outside the standard range.
• Maintain tool shank tolerance at h6 for optimal performance.
• Verify balancing quality to G6.3 at 15,000 rpm to ensure machining precision.
