A machine for working glass slabs includes a supporting structure, a slab grinding section having grinding heads, a conveyor assembly adapted to move the glass slab, and a slab drilling section having a conveyor adjacent to the conveyor assembly. The slab grinding section has suckers for keeping the glass slab next to a working plane spaced and/or offset with respect to the advancement plane, and a computerized numeric control assembly to perform workings on the glass slab.

The present invention provides a device for removing internal blockage materials (10) from a fluid-conveying line (3), said device comprising a cutting tool (9) activated by a rotary actuator (8), in which: the cutting tool (9) is positioned at the front of the device; and the cutting tool (9) comprises a diameter that is smaller than the internal diameter of the fluid-conveying line (3).

The purpose of the present invention is to, after a through-hole is formed in a plurality of members between which a sealant is applied, rapidly and easily remove the sealant flowing into the through-hole. This through-hole forming method is provided with: a step (S2) in which a cutting tool rotates about the axis thereof, thereby forming a through-hole in a plurality of members between which a sealant is provided; and a step (S4) in which after the through-hole is formed, the cutting tool continues the rotation about the axis thereof for a predetermined time or a predetermined number of rotations, thereby removing the sealant flowing into the through-hole.

A method of assembling an aircraft assembly having a first member and a second member includes drilling at least one first opening through the first member, the at least one opening having a first diameter, and drilling at least one second opening through the second member, the at least one second opening having the first diameter. The method also includes forming a chamfer on the at least one first opening and the at least one second opening, the chamfer having a chamfer diameter, and positioning the first and second members to align the at least one first opening and the at least one second opening. The method further includes drilling the at least one first opening and the at least one second opening to a second diameter, wherein the second diameter is greater than the first diameter.

A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.

A method for deep drilling into a panel composed of compressed polyester fibers includes providing a guide system, aligning the guide system with the panel, applying a force to a face of the panel, and drilling a hole into the edge of the panel with the guide system and the drill while the force is applied to the face of the panel. The guide system supports a drill having a drill bit for movement in an axial direction. The force is applied to an area of the panel that is in axial alignment with the guide system.
