Coolant Type Specifications and Cutting Conditions

This document provides detailed specifications and guidelines for coolant types, cutting conditions, and tooling options for machining applications, focusing on fixed and flexible types of tapping attachments and endmills.

1. Coolant Types and Feeding Methods

• Fixed Type: Supports internal coolant supply directly. Center-through coolant feeding can be enabled by adding a coolant unit and coolant collet. This type offers higher rigidity compared to flexible types.
• Flexible Type: Allows setting any tilt angle between 0° and 90°, enabling machining from different angles without a tilt table, reducing setup and plant investment costs.
• Internal Coolant: Enables through-the-tool coolant feeding, providing precise coolant delivery to the cutting zone.
• External Coolant: Traditional coolant supply method.

2. Cutting Conditions and Examples

Guidelines for cutting conditions are provided for 2-flute HSS endmills of 10mm and 20mm diameters, including parameters such as depth of cut, rotational speed, cutting speed, feed, and feed per rotation. Examples include machining of materials like S55C, FC250, and A2017 with specified speeds and feeds.

3. Tooling Types and Specifications

• Tapping Attachments: Available in fixed and flexible types with maximum rotational speeds up to 6000 min-1 (depending on size), chucking capacities ranging from φ0.5 to φ25, and tapping capacities from M3 to M22.
• Adapters and Collets: Various sizes and types (e.g., AH, AH-OH, AHS, AHL) are listed with corresponding chucking and tapping capacities, axial compensation, and tilt angles.
• Quick-Change Tapping Attachments: Designed for compression and tension tapping with specific tool and work material compatibility.

4. Design Features and Benefits

• Fixed type offers higher rigidity and supports internal coolant supply for improved machining performance.
• Flexible type allows machining at various tilt angles without additional equipment, enhancing versatility.
• Standardized internal coolant system enables pinpoint coolant delivery, improving tool life and machining quality.
• Center-thru coolant types are available upon request for BT40 and BT50 tool holders.

5. Ordering and Accessories

• Ordering examples are provided for various tool holders and adapters, including CAT40, CAT50, BT30, BT40, and BT50 types.
• Collets and spanner wrenches are sold separately, with references to specific pages for ordering details.
• Positioning blocks (A dimension) are used for accurate setup and are referenced in the ordering examples.

6. Dimensional Data and Part Numbers

The document includes extensive dimensional data for different tool holders, adapters, and coolant units, specifying parameters such as lengths (L1, L3, L4), diameters (d, D, D1, D2), and angles (±90°, 0°-90°, 10°, 45°, 90°). Part numbers are systematically listed for easy identification and ordering.
