Product catalog summary

Overview

This document provides comprehensive technical specifications, model details, accessory information, and operational guidelines for the MEGA series and related toolholders, collets, chucks, angle heads, and spindle components used in high-precision, high-speed machining applications. It emphasizes compliance with DIN 69893-1 and ISO 12164 standards, coolant integration, and compatibility across various machining environments.

1. Product Range and Types

MEGA Series Toolholders: Includes Micro Chuck, New Baby Chuck, E Chuck, Double Power Chuck, ER Grip, Hydraulic, Shrink, and Mold Chucks designed for a wide range of tool diameters and machining needs.
Additional Components: Face Mill Arbors, Synchro Tapping Holders, Angle Heads (AG90, AG45, AGU types), Air Turbine Spindles, and DYNA TEST equipment for performance verification.
Collet Variants: NBC series, MPS series, and MICRO COLLET G2, covering clamping ranges from 0.25 mm to 42 mm.

2. Design Features and Standards

Taper-off Design: Minimizes interference and maximizes rigidity for improved machining accuracy.
High-Speed Capability: Models support rotational speeds up to 35,000 min-1, with air turbine spindles reaching up to 80,000 min-1.
Clamping Ranges: From ultra-small diameters (0.25 mm) to large sizes (42 mm), accommodating diverse tooling.
Standards Compliance: All components conform to DIN 69893-1, DIN 69893-5, DIN 69893-6, and ISO 12164 Form A standards, ensuring interchangeability and quality.
Coolant Integration: Coolant-through holes and grooves are featured in many models; coolant pipes are optional and must be ordered separately.
Adjusting Screws: Optional for controlling tool insertion depth on compatible models; some models explicitly do not support them.

3. Model Specifications and Parameters

Detailed dimensional data including clamping ranges, maximum rotational speeds, lengths, diameters, heights, and weights are provided for each model.
Examples include HSK-A40, HSK-A50, HSK-A63, HSK-A100 MEGA series, NBC collets, and various angle heads.
Maximum speeds vary by model and size, ranging from 1,500 min-1 (face mill angle heads) to 80,000 min-1 (air turbine spindles).

4. Accessories and Spare Parts

MEGA Nuts, sealing nuts, adjusting screws, wrenches (MEGA WRENCH, C-SPANNER), protective cases, and taper cleaners support assembly, maintenance, and operation.
Coolant pipes (various models such as C1, C3, C7, C9, C11, C13, C15, C16, C19, C21, C22, C25, C27, C38, C40, C42, C44, C45, C46, C47, C48, C50, C51) are optional and model-specific.
Exclusive stop blocks are mandatory for certain angle heads and spindle types to ensure proper positioning and coolant supply.

5. Special Features and Recommendations

High Rigidity and Precision: Integral rigidity close to solid toolholders with flange contacting nuts for maximum stability.
Micro Diameter Design: Optimized for high-speed applications in confined spaces.
Compatibility Notes: Users must verify compatibility of collets, adjusting screws, and coolant pipes before ordering; mixing components from different manufacturers is discouraged.
Coolant and Threading: Some models lack internal threads; coolant pipes must be ordered separately to enable coolant-through functionality.
Usage Guidelines: Use cutting tools with shank tolerances within h5 or h6; avoid roughing endmills or flat shank tools with hydraulic chucks; always insert tools beyond minimum clamping length; do not tighten clamping screws without tool insertion.

6. Technical Tables and Data Highlights

Extensive tables provide critical data such as:

Model numbers with corresponding clamping ranges, maximum insertion lengths, weights, and coolant supply methods.
Dimensional parameters including lengths (L, L1, L2), diameters (øD, ød), heights (H, H1, H2), and adjustment lengths (H).
Accessory compatibility and special notes on coolant pipe ordering and adjusting screw usage.

Examples from tables include:

Model	Clamping Range (mm)	Max Speed (min-1)	Weight (kg)	Coolant Supply
HSK-A40-SRC	6 - 12	Up to 35,000	0.32 - 0.46	Through bore
MEGA 6E	3 - 8	30,000	0.8 - 0.9	Coolant-through hole
AG90 Compact	Various	5,000	1.0 - 7.9	Through locating pin

7. Standards and Compliance

All products comply with DIN 69893-1 and ISO 12164 Form A standards, ensuring interchangeability and quality assurance.
Collet chucks conform to DIN V 69893-6 Form F for high concentricity and rigidity.
Users are advised to consult operation manuals for compatibility with heating/cooling equipment and machine tool functions such as rigid tapping.

8. Operational Recommendations and Limitations

Use carbide cutters with specified tolerances (h5 or h6) for optimal clamping accuracy and tool life.
Coolant pipes and accessories must be ordered separately; dry running of coolant-dependent components is prohibited.
Cleaning clamping bores with wiper or TK cleaners is essential for maintaining precision.
Adjusting screws are not compatible with certain marked models; verify before use.
Do not mix components from different manufacturers to avoid accuracy loss.
Stop blocks are mandatory for certain angle heads and spindle types to ensure proper coolant supply and positioning.

Conclusion

This document serves as a detailed technical reference for engineers and technicians selecting and operating MEGA series toolholders, collets, chucks, angle heads, and spindle components. It highlights critical specifications, accessory options, and operational best practices to ensure high-speed, high-precision machining performance compliant with international standards. Proper component compatibility, coolant integration, and adherence to usage guidelines are essential for optimal tool life and machining accuracy.
