Product Overview
This unit is part of a series of durable, heavy-duty flange facing machines, designed to combine both facing and milling capabilities.
Robust Mechanical Design
Heavy-Duty Construction: Features large, structural-grade bearings that deliver powerful, stable performance across the entire machining range, even when working over bolt hole patterns.
High-Torque Capability: An oversized gear ring withstands extreme torque, making it suitable for demanding flange repair jobs and capable of producing a schlieren surface finish.
Versatility & Flexibility
Feed Systems: Utilizes a pneumatic feed box for radial and axial feed, with manual feed options available for rapid positioning.
Remote Control & Safety: Feed rates can be adjusted remotely via a pneumatic control unit, ensuring maximum operator safety while allowing for flexibility during the machining process.
Variable Speed: Feed rates are infinitely variable from 0.002–0.035 inches (0.0508–0.889 mm) per revolution, offering high operational flexibility.
Reversible Gearbox: The reversible feed box allows for flexible installation to achieve either radial or axial feed.
Adjustable Arms: Both the rotating arm and counterweight arm are adjustable to achieve the desired swing clearance and machining range.
360° Tool Head: The cutter head rotates a full 360°, allowing for the machining of various chamfers, O-ring grooves, lens rings, and other angled surfaces as required.
Drive Options: Available with both pneumatic and hydraulic drive options.
Mounting Versatility: Features a removable chuck system for face-mounting the machine. Supports OD (Outer Diameter) mounting, ID (Inner Diameter) mounting, or surface mounting.
Milling Option: Optional milling functionality with a precision down-feed ball screw is available.
Quick & Easy Installation
Modular Design: Designed with modularity in mind; multiple machine components can be removed for easy installation and storage.
Simplified Assembly: The unique chuck system reduces the number of parts, significantly streamlining the machine setup and dismantling process.
Rapid Leveling: Quick-adjust leveling feet make the installation process fast and convenient.
