Project Description

FDG4500 Circular Mill

It is mainly uses milling processing methods,max face cutter diameter can reach 300mm, Specifically developed for the machining of large flanges, such as wind tower or large、 crane base machining

Facing Range: 79.0 – 178.0″ Clamping Range: 79.0 – 176.0″


  • Large, heavy-duty construction-grade bearing
  • 2 output hydraulic power unit
  • Milling spindle head with #50 taper spindle easily handles face mill up to 12 inches (300.0mm) in diameter

FDG4500 Circular Mills is designed for machining of large flanges, wind turbine rotor blades and wind turbine tower flanges. Crane pedestals and heavy construction and mining.

Precise Bearing & Steady Main Body

Provide the most powerful guarantee for machining using precise bearing & steady main body, equipped with adjustment leg and Jacking leg, various sizes of feet, Easy and fast to install on site.

Smooth Cutting

All feed of Milling spindle head adopt precision machined dovetail ways and adjustable Turcite-B coated gibes provide smooth accurate travel.

Rotary Joints

Solve the problem of oil hosing winding using rotary joints when the machine is rotating.

Drive Unit

The machine is driven by 4HP hydraulic motor to achieve effectively eliminates the gap of the gears and smooth cuttting. Hydraulic power unit provides the greatest possibility for cutting. It can achieve cuts up to a maximum depth of 2mm on flanges.
