A method for welding profiled elements in plastic material, includes the steps of: preparing two profiled elements, arranged with respective zones to be facing one another; making a groove in correspondence to at least one zone, by a removal operation on a peripheral edge of at least one profiled element; heating the zones to be welded; coupling the zones to be welded to one another, pressing the profiled elements one against the other so as to keep the zones to be welded in reciprocal contact. The coupling step includes: melting the zones to be welded into one another in order to define a welding bead; making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

A method for welding profiled elements in plastic material includes: preparing two profiled elements, arranged with respective weld zones facing one another; making a groove corresponding to at least one weld zone of the profiled elements, the grooving performed by a removal operation on a peripheral edge of at least one profiled element; heating the weld zones; coupling the zones to be welded to one another, pressing the profiled elements together to keep the zones to be welded in reciprocal contact. The coupling step includes: a sub-step of melting the zones to be welded into one another in order to define a welding bead; a sub-step of making a containing compartment defined by the groove, the welding bead being made internally of the containing compartment; and the step of arranging a containing presser in correspondence to the containing compartment for preventing exit of the welding bead from the compartment itself.

A drilling apparatus comprising: at least one bit; a vacuum shroud, including a compressible boot, disposed around a longitudinal axis of the apparatus and configured to be in operative communication with a vacuum attachment port; and at least one magnetic element disposed near a distal end of the apparatus and configured to attract metallic debris resulting from drilling apparatus operation.

A machine tool includes a spindle to which a tool is attached, and a table configured to support a workpiece, and machines the workpiece by the tool by moving the spindle and the table relative to each other. The machine tool includes a box-shaped cover member placed on the table and configured to be open on the spindle side, and a lid member attached to a column configured to support the spindle, the lid member being configured to cover the spindle side of the cover member, the lid member including an insertion hole formed therein through which the tool can be inserted. Following the relative movement between the spindle and the table, the lid member and the cover member move relative to each other as viewed in a plane intersecting with the axial direction of the spindle.

A machine tool includes: an exterior cover covering a machining area where a workpiece on a worktable is machined by a machining tool; an articulated robot arranged inside the exterior cover and configured to replace the workpiece; a controller configured to control the posture of the articulated robot and the coordinate point at which a hand of the articulated robot is positioned; and a protective cover arranged inside the exterior cover and configured to protect at least the hand from scattered matter arising due to machining of the workpiece when the articulated robot is set at a predetermined posture or when the hand is moved to a predetermined coordinate point.

A debris collecting rotary tool attachment for collecting debris during rotary tool use includes a shell that comprises a wall. The wall extends from a top to a bottom of the shell and has an inner face. The inner face is tackified, such that the inner face is configured to sequester debris on the inner face of the shell. The top and the bottom are open, defining respective perimeters. A fastener is coupled to the bottom and extends around the perimeter of the bottom. The fastener is configured to sealably couple the shell to a chuck end of a rotary tool. The shell is positioned around a cutting tool secured in the chuck of the rotary tool. The inner face is tackified to sequester debris generated during operation of the rotary tool.

A device for welding profiled elements in plastic material includes: a base frame supporting retaining members of respective profiled elements, to engage the profiled elements with corresponding zones to be welded facing one another; a heater for heating the weld zones of the profiled elements; a unit to move the retaining members, to shift the profiled elements between a first reciprocal away direction and a second reciprocal closer direction wherein the zones to be welded are coupled together; and a removal unit utilizing milling The removal unit includes: a supporting frame positioned in correspondence to the retaining members; at least one machining tool; a motor part associated with the tool; and a movement member of the tool, to move it between a first idle condition and a second working condition wherein it is placed between the profiled elements.
