Gantry laser cutting machine is characterized by the beginning not move relativ

Trapezoid slit sieve is mainly used CNC laser processing machine, the first cantilever and gantry there are two ways. Characterized cantilever machine processing, all the screen does not move, along a laser incision into the workpiece to move in the axial direction for high-speed, high-efficiency cutting. Cantilever machine for the aluminum plate welded into the frame structure, strength and stiffness, can be used to prevent excessive movement speed when moving, spot drift and other defects. Gantry laser cutting machine is characterized by the beginning not move relative to the laser-cut screen Begin the turn with indexing and movement in the axial direction. All good machine rigidity, stable laser output. Because the screen long Suppliers heavy, slow displacement speed, handling more difficult as well. Composite slotted screen processing machine tool commonly used is the cantilever.
Slotted screen laser processing machine and practices plate CNC laser cutting machine to compare the maximum that it is not the same clamping indexing organizations, support screen and dragging equipment. Rotary indexing clamping tissue and peripheral end of the primary process to screen position, screen support, and drag the end of the primary device screen and drag the screen to avoid overhanging deformation, generally need to use CNC laser processing machine for processing.
Cloth pipe joints in the axial direction, each must be slotted in the axial direction from the uniform on the screen the same bus, constitute a seam, the whole screen uniform root dozens of columns slotted. Pipe laser cut with conventional machining with a relatively high efficiency, high precision machining, processing a wide scale advantages.
The tubular body mounted on a bracket, one end fixed by the rotation of the support, the other end is clamped NC rotary back, make sure the machine parallel to the tube axis and the x-axis; tangential beginning to move in the machine Z, the focal position is located on a punch, and adjust the cutting nozzle and the beginning of the appearance of the screen interval to a preset value: adjust the laser cut at the beginning, so cut at the beginning of the optical axis located in a vertical plane through the tube axis, and cut at the beginning of the gas nozzle located the highest point of the tubular body Office; using pulsed light in the slotted end punch will penetrate the screen, and then, by a laser pulse into a series, the focus changes to the cut position, cut at the beginning of the axial direction along the screen cut, sew a ladder processed trapezoidal side: the screen is rotated counterclockwise angle of a trapezoid is equal to a seam taper I / 2), so that a trapezoidal side slit in a vertical orientation, the beginning of the cut pan left δ = (D / 2) Sina- △ ( D is the outside diameter, △ is a technical adjustment value, and screen wall thickness, the laser output power and so on), make sure to cut the head of the nozzle to adhere to the same screen appearance intervals: after a long slit cut into the planning. Clockwise rotation of the sleeve 2a angle cut at the beginning of pan left 2δ, then return along the ladder stitch cut out another ladder screen surface, a machining end intact trapezoidal joints: In accordance with the same operation, the circumferential re-start, you can end the entire root screen processing.
