Overview
Precision facing on very large flanges
The LDFM is made for precision flange facing on large-scale jobs. It offers both rotary milling and single-point tooling, and it handles diameters up to 229 in.
Flexible segmented legs fit interior diameters from 55 in to 185 in closely, which speeds setup. The adjustable rotary hub moves independently of the mounting legs to produce flat, accurate surfaces, and a rigid tubular beam reduces vibration for smoother results.
With milling, the cutting range is 55 in to 205 in, or up to 229 in with the extension bracket. With single-point tooling, the range is 55 in to 204 in, or up to 224 in with the bracket. The head travels 59.5 in on the X axis and 7 in on the Z axis.
Applications
Where the LDFM is used
The LDFM brings flange machining to parts too large to move to a shop.
Large flange facing
Milling flange faces flat and accurate on diameters up to 229 in.
Single-point finishing
Single-point tooling on faces from 55 in to 224 in with the extension bracket.
Large-scale facing jobs
Long 59.5 in X-axis travel covers wide sealing faces in one setup.
