The FDG3500 can be configured for single-point machining, face milling, or both functions together. Hydraulic, pneumatic, and electric drive options are available, allowing users to select a configuration suited to their operating conditions and machining requirements.

Key Features and Benefits

1. Combined Single-Point Machining and Face Milling

The FDG3500 integrates single-point machining and face milling functions in one versatile system. Users can select single-point machining only, face milling only, or a combined configuration to suit different flange repair and surface machining tasks.

2. Large-Diameter Flange Machining

With a facing range of 45–138 inches, the FDG3500 is designed to handle large flange sealing surfaces in demanding industrial maintenance and repair applications.

3. Heavy-Duty Precision Bearings

Large, heavy-duty bearings provide load-bearing support for stable machine operation during high-load machining. This robust design is intended to support consistent performance during demanding on-site work.

4. Face Milling Spindle with #40 Taper

The milling spindle head features a #40 taper spindle and can accommodate a face mill up to 6 inches (160 mm) in diameter, according to the supplied specifications. This capability expands the machine’s versatility for face milling applications.

5. Standard Two-Output Hydraulic Power Unit

The FDG3500 features a standard two-output hydraulic power unit, supporting its hydraulic drive configuration and the machine’s machining functions.

6. Multiple Drive Options

Hydraulic, pneumatic, and electric drive options are available. This flexibility allows users to choose a drive system based on site conditions, available power sources, and machining requirements.

7. Optional Grinding Capability

The FDG3500 can be equipped with a grinding unit for applications requiring precision grinding of flange surfaces, extending its potential use beyond conventional flange facing.
