Lightweight tools line for large diameter boring

Product catalog summary
Overview: The document details the MACRO BOHR modular boring system designed for heavy roughing and precision finishing of large diameter bores ranging from Ø 220 mm to 1020 mm. The system utilizes high-strength aluminum plates to reduce tool weight and features interchangeable components for flexibility and efficiency.
Specifications: The system includes eight aluminum plates, each offering a 100 mm boring range. It supports finish, rough, and reverse boring, as well as outside diameter turning. The system is compatible with a variety of arbors to meet diverse user needs.
Key Features:
  • Lightweight Design: High-strength aluminum plates reduce tool weight.
  • Easy Adjustment: Boring heads and counterweights have two radial positions for maximizing the boring range.
  • Secure Assembly: Tapered screws provide high axial pressure for stability and rigidity, minimizing vibrations.
  • Reliability: Components are made from hard-coated aluminum and Nickel-Chrome alloy steel for accuracy and repeatability.
Procedures:
  • Heavy Roughing: Utilizes two cartridges with various standard insert geometries. Adjustments are made via the boring head and cartridge screws, with a safety lock provided by the locking screw and nut. Cutting angles of 75º or 90º are available.
  • Precision Finishing: Uses one cartridge with high precision adjustment through a graduated dial with 0.002 mm accuracy.
Components:
  • Finish Boring Head: Detailed on page 13.
  • Finish Cartridges: Detailed on page 13.
  • Counterweight: Detailed on page 14.
  • Aluminum Plates: Detailed on page 12.
  • Adaptor and Extensions: Optional components detailed on page 11.
  • Arbors: Available in adaptor mount and direct mount configurations, detailed on pages 9-10.
Applications:
  • Finish Boring: Overview on page 4.
  • Outside Diameter Finish Turning: Overview on page 5, with a turning range of Ø 0 ~ 724 and a maximum depth of 79 mm.
  • Reverse Finish Boring: Overview on page 6, requires entering through a previous hole.
  • Rough Boring: Overview on page 7.
  • Outside Diameter Rough Turning: Overview on page 8, with a turning range of Ø 0 ~ 724 and a maximum depth of 70 mm.
Conclusion: The MACRO BOHR system offers a versatile and reliable solution for large diameter boring, with a focus on lightweight design, secure assembly, and precision. It is suitable for a range of applications from roughing to precision finishing.
