A debris control apparatus comprising a debris control enclosure, the enclosure further comprising a vacuum opening in the enclosure. The vacuum opening being sized, shaped and positioned to receiving a vacuum conduit, connected to a vacuum source, for extracting the debris from the enclosure. The debris control apparatus further comprising a mounting assembly for mounting the enclosure to a machine, such that, during operation, the enclosure moves along the work material as the cutting tool moves along the work material, the enclosure being mounted independent of movement of the cutting tool in and out of the work material. The mounting assembly comprises a depth adjuster for adjusting the operating depth of the enclosure. The depth of the enclosure can be adjusted such that the debris will be contained in the enclosure during operation.

An acoustic panel (200) for an aircraft nacelle (100) may comprise a perforated first skin (220), a second skin (230), and a core (210) sandwiched between them. A damaged portion of the perforated first skin may be removed. A fiberglass ply (510) may be coupled to the acoustic panel. A pressure differential may cause the fiberglass ply to form dimples (515) within the perforations (325) of the first skin. The fiberglass ply may be used as a template to drill holes in a replacement patch (400).

A rim drilling and milling machine has a base (10), a column (20), a turret (30), a saddle (40), a table (50), and a fixture unit (60). The fixture unit (60) has a foundation (61) and four clamping seats defined as two first clamping seats (63A) and two second clamping seats (63B). The first clamping seats (63A) are slidably mounted on the foundation (61) along a first radial direction, and are disposed at positions diametrically opposite in the first radial direction. The second clamping seats (63B) are slidably mounted on the foundation (61) along a second radial direction perpendicular to the first radial direction, and are disposed at positions diametrically opposite in the second radial direction. The four clamping seats can clamp at four equiangular points of a wheel rim.

A machining center for machining profiles may include: a base having a longitudinal axis, the base defining a work surface extending with first and second ends along the longitudinal axis, wherein the base is configured to receive a profile manually laid along the longitudinal axis of the base by an operator or by a specially-designed automatic feeder; a plurality of support and lock members for supporting and locking the profile on the base, wherein each of the support and lock members can be placed on respective profiled guides which extend parallel to the longitudinal extent of the base between the first and second ends, and wherein each of the support and lock members is displaceable independently along the longitudinal extent of the base; a pair of vertical columns, each of the columns supporting at least one first motorized spindle; and/or a portal structure, comprising an upper beam, above the base.

A machining center for performing a plurality of machining operations, such as drilling, milling, cutting, using rotating tools, on metal profiles having a longitudinal extent greater than their cross-section dimension, particularly but not exclusively made of aluminum. The machining center comprises a base defining a work surface extending longitudinally with first and second ends, upon which the profile is manually laid by an operator or by a specially-designed automatic feeder. The base has a plurality of members thereon for supporting and locking the profile, as well as a pair of vertical columns for supporting motorized spindles, each column being located next to said base and being configured to being displaced in either direction, parallel to the longitudinal extent of the base along respective slide guides located next to said base. Each vertical column is equipped with a first carriage configured to vertically sliding in either direction along its respective column and with a second carriage mounted to the first carriage, and configured to sliding in either direction perpendicular to its respective column. The center also comprises a portal structure whose upper beam above said base is equipped with a motorized spindle for rotating tools, mounted to a support body configured to angular displacements around a pivot for rotating about a first axis parallel to the longitudinal extent of the base.
