Abstract
Abstract A portal milling machine for machining work pieces of considerable height and length, in which the transverse beam carrying carriage means movable in the longitudinal direction of said beam and transverse thereto is displaceable on supporting means arranged on opposite sides of and at a higher level than a chucking plate at the bottom of a longitudinal pit below said beam while at least one vertical arm connected to said beam extends downwardly into said pit and has displaceably mounted thereon an additional carriage with a substantially horizontal axially displaceable spindle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
152 words
In combination with a floor having a pit therein with longitudinal chucking means connected to the bottom of said pit for chucking a work piece thereto, a portal milling machine which comprises: a transverse beam extending transverse to said chucking means and in vertically spaced relationship thereto. lateral guiding means located on opposite sides of said pit at approximately the level of said floor, two bed carriages movable on said lateral guiding means and respectively connected to the ends of said transverse beam and supporting the latter, driving means drivingly connected to said bed carriages for moving the same in unison with each other, at least one of said bed carriages having a substantially vertical arm connected thereto, and lateral carriage means vertically displaceably mounted on said substantially vertical arm, the lower end of said arm extending at least to the chucking plane of said chucking means permitting downward tool side machining.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
60 words
An arrangement in combination below the floor according to claim 1, in which said transverse beam is provided with transverse guiding means extending in the longitudinal direction of said transverse beam, and which includes transverse beam carriage means displaceably mounted on said transverse guiding means and including additional carriage means displaceable in a direction transverse to said transverse guiding means.
