US 11,167,359 B2 · Portable machine tools, kits, and methods for machining annular and straight planar surfaces

Abstract

Methods comprise machining each of an annular planar surface and a linear planar surface of a workpiece using a combination flange facer and milling machine. Methods comprise using a machine frame of a flange facer and a rotating ring of the flange facer to mount a milling machine to a workpiece, and machining the workpiece using the milling machine when it is coupled to the rotating ring of the flange facer. Portable machining kits comprise a flange facer and a milling machine that is configured to be operatively mounted to the rotating ring of the flange facer. Portable machine tools comprise a machine frame, a rotating ring, a bridge coupled to the rotating ring, a facing tool head assembly configured to be selectively coupled to and decoupled from the bridge, and a milling tool head assembly configured to be selectively coupled to and decoupled from the bridge.

Dependent claims

A portable machine tool, comprising:

a machine frame configured to be fixedly coupled to a workpiece to operatively support the portable machine tool on the workpiece;
a rotating ring that is rotatingly coupled to the machine frame, wherein the rotating ring comprises a linear bed;
a bridge coupled to the rotating ring, wherein the bridge is configured to be selectively translated along a length of the linear bed;
a facing tool head assembly configured to be selectively coupled to and decoupled from the bridge, wherein the rotating ring is configured to be selectively rotated relative to the machine frame to rotate the facing tool head assembly to operatively machine an annular planar surface on the workpiece when the facing tool head assembly is coupled to the bridge;
and
a milling tool head assembly configured to be selectively coupled to and decoupled from the bridge, wherein the bridge is configured to selectively translate the milling tool head assembly along the bridge to operatively machine a linear planar surface on the workpiece when the milling tool head assembly is coupled to the bridge.
