Anti-Vibration Arbor (Damped Arbor)

Product catalog summary

Introduction
The document discusses the Anti-Vibration Arbor (Damped Arbor), which is engineered to minimize chattering vibrations and boost machining efficiency, particularly effective for operations with long overhangs, thereby enhancing productivity.

Specifications and Features
The Anti-Vibration Arbor may undergo specification changes for improvements. It is printed with soybean ink and distributed by Hitachi Tool Engineering across Europe, China, America, Thailand, and India.

Field Data and Performance
Case studies from companies A, B, C, and D highlight the arbor's effectiveness. Company A shifted from electro-discharge to cutting machining, while Company B achieved stable cutting, eliminating surface finishing and increasing efficiency by 57% compared to steel arbors.

Product Specifications
Details include item codes, stock availability, and dimensions for various arbor models like BT50 and HSK types. Correct AV unit usage is crucial for optimal damping effects.

Recommended Cutting Conditions
Guidelines emphasize forward rotation (M03) to prevent breakage and recommend using air blowers or coolants to avoid internal part deterioration from heat.

Maintenance and Overhaul
Annual overhauls are advised to maintain damping effects, as consumables may degrade over time.

Conclusion
The Anti-Vibration Arbor significantly enhances machining stability and efficiency, with comprehensive specifications and maintenance guidelines provided for optimal performance.

Specifications and Recommendations
1. Round insert cutters (AR shape) are recommended for face milling; high-feed machining cutters (ASR, ASRT, ASRF shapes) for die-sinking.
2. The recommended depth of cut (ap) is calculated with the width of cut (ae) being 80% of the tool diameter (Dc).
3. Consumables inside the product may deteriorate, necessitating periodic overhauls, approximately once per year.
4. For overhaul details, contact the Hitachi Tool sales office.

Cutting Conditions and Performance
1. Cutting speed (vc), feed per tooth (fz), and axial depth of cut (ap) are specified for various materials and cutter types.
2. Use air blow or coolant during cutting to prevent internal part deterioration due to heat.
3. Always use forward rotation (M03) to avoid breakage.

Graphical Data
1. Graphs compare cutting regions for AV arbor and carbide shank, and AV arbor and standard steel arbor during shoulder cutting.
2. Axial-depth of cut comparisons are provided from pocket machining test results.

Field Data and Results
1. Company A transitioned from electro-discharge machining to cutting machining.
2. Company B achieved stable cutting, eliminating the need for surface finishing.
3. Compared to steel arbors, AV arbors provided stable cutting with increased efficiency and cutting depth.

General Notes
1. Do not disassemble the AV unit to maintain damping ability.
2. Store the unit upright if not used for a long period.
3. Specifications are subject to change without notice for improvements.
