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.

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 cutting machine waste extraction apparatus is provided for a cutting machine that cuts a plate where the cutting machine waste extraction apparatus is supported adjacent a cutting area at a cutting table. The cutting machine produces waste at the cutting area during the cutting of the plate where the apparatus includes a ducting system having a first duct that receives the waste from the plate, and a second duct that receives the waste from the first duct. The first duct is movable along the length of the second duct and the second duct includes a lengthwise opening which is sealed by a flexible belt. The flexible belt is deformable from sealed contact with the second duct, adjacent a junction apparatus, where the junction apparatus provides a fluid connection between the first duct and the second duct.

A key cutting machine includes a housing, carriage, key clamp, and motor to drive the carriage. The key cutting machine may include a vacuum removably attached to the housing. The key cutting machine may be selected between manual, automatic, and semi-automatic user modes. Additional improvements or features of a key cutting machine are also described.

An assembly for controlling waste material during a hybrid subtractive and additive manufacturing process is disclosed, including a machining tool held in a holder, a shroud disposed around the machining tool, and one or more ports configured to create a negative pressure within the shroud. A method of constraining waste material during a hybrid subtractive and additive manufacturing process of a part includes adding an amount of material to a part being additively manufactured, transforming the amount of material that was added, manipulating a tool to machine a portion of the part being additively manufactured and generating a waste material, sealing a portion of the tool and covering a portion of the part with a shroud, and applying a negative pressure to create an airflow to prevent the waste material from exiting the shroud.

A key cutting machine includes a housing, carriage, key clamp, and motor to drive the carriage. The key cutting machine may include a vacuum removably attached to the housing. The key cutting machine may be selected between manual, automatic, and semi-automatic user modes. Additional improvements or features of a key cutting machine are also described.
