The present disclosure relates to a cutter clamp (8, 37) that comprises a first arm part (10, 39) and a second arm part (11, 40), where the arm parts (10, 11; 39, 40) are arcuate and arranged to adjustably at least partially enclose a major part of a circumference (57, 63) having a center (58, 64). The cutter clamp (8, 37) comprises at least one hollow rod (21, 22; 48, 62) arranged for receiving a mounting rod (36) for a power cutter (1, 56) in a pivoting manner. The smaller circumference the arm parts (10, 11; 39, 40) are adjusted for, the closer to the center (58, 64) said hollow rod (21, 22; 48, 62) is moved. The present disclosure also relates to a cutter clamp attachment device (68), a cutter clamp kit and a cutter clamp holding frame (76).

A plasma-torch cutting machine gantry moves in a first axis and the torch mounted through a pantograph to a drive box moves along the gantry in a second axis. The drive box rotates the torch about a third axis, and tilts the torch about a fourth axis. The drive box moves vertically in a fifth axis. The torch is mountable with tip at pantograph focal point or in an extended position. A controller firmware computes and apply offsets in the first, second and fifth axis to maintain the plasma torch tip in desired position despite the torch being mounted in extended position, rotation and tilt of the torch. In embodiments the torch is rotatable −/+90 degrees from vertical; and a laser scanner maps surfaces and edges of beams to determine movements and rotations for cutting beams.

An apparatus for volume reduction of material removed from a hazardous environment. The apparatus includes a shielded housing for receiving a workpiece therein, at least one cutting unit having a cutting head operable for contactless cutting, and a drive unit for rotating the at least one cutting unit around a main axis so the cutting head cuts the workpiece.

A cutting device capable of efficiently cutting an object with a simple configuration includes a grasp unit including a first grasper and a second grasper movable in an opening and closing directions to grasp the object, a cutting unit disposed side by side with the first and second graspers and moved in a cutting direction along the opening and closing directions to cut the object, and a position setter setting a cutting start position and a cutting end position based on respective positions of the first and second graspers that are grasping the object, respectively.

Drawing device for drawing a tool (T), comprising: a support (2), provided with rests (21), structured to be slidably arranged in contact with an inner wall of a tube, and an attachment (22) for a tool (T); a cursor (3), movable along a longitudinal direction (Y) between at least a starting position and a return position; magnetic means (4), predisposed to magnetically constrain the support (2) and the cursor (3) with respect to the displacement along the longitudinal direction (Y).

A portable device for precision plasma and oxy-fuel torch cutting is provided. Versions of an example portable cutting torch tool guide the gun of a cutting torch to make precision linear cuts or curved cuts in a metal workpiece. In an implementation, the device is a gun for a cutting torch, with an integrated rail follower and adjustable vertical and horizontal offsets from a workpiece. The cutting torch tool may use various kinds of rails for stable cuts, with optional movement damping, motorized drive, servos for vertical and horizontal offset, and remote control with user interface.

The laser processing machine includes a beam oscillation mechanism that oscillates a beam spot on a surface of a sheet metal. The control device controls the beam oscillation mechanism so as to oscillate the beam spot with an oscillation component in a direction orthogonal to a cutting direction of the sheet metal in a non-holding region, in which a holding portion of the conveyance apparatus for conveying a product is not held, when cutting the product from the sheet metal by irradiating the sheet metal with the laser beam. The non-holding region is at least a part of a periphery of a protrusion portion of the product, or at least a part of a periphery of a recess forming region in which a recess of the product is formed.

The present device is configured for mounting on and movement around the outside surface of a pipe to be processed, and comprises a clamping device and a flexible composite carriage consisting of at least two pivotally connected component parts capable of pivoting about a pin of a hinged connection lying parallel to the axis of the pipe to be processed, wherein each part comprises a group of at least two coaxial supporting rollers, the axis of which is situated at a distance from the hinged connection that is less than or equal to of the distance between the hinges of the component part and is parallel to the axis of the pipe to be processed. The component parts are connected in succession in such a way that each part bears on two groups of supporting rollers, one of which is mounted on the component part, and the other of which is mounted on an adjacent component part.
