Cutting machine for cutting the control points to bear in mind!

Cutting machine as a cutting machine of current application range is very wide, in recent period of development, the cutting machine cutting technology is more and more mature, can cut things more and more, here, let us together to learn about the cutting machine for cutting the control points, hope can help you to the front of the screen. Cutting machine cutting control 1, selection of arc starting point in normal circumstances, cut into pieces of circular arc starting point should be at the edge of the sheet metal or cut the slit in the middle of the workpiece. When the distance is too big, there will be no or broken arc, arc parts, cutting by product waste or scrap. When the distance through the hours, because the short circuit between the nozzle and the workpiece, it is easy to burn out the nozzle, destroy the normal cutting process. The practice proved: the height of the nozzle is apart from the artifacts for 6 - commonly 8 mm, nozzle distance air cutting machine and water recompression arc cutting height is slightly less than 6 - 8 cm. 2. Select the correct direction should ensure that the cutting blade mostly separated from main board. If prematurely from motherboard, peripheral Angle box is not enough to resist the thermal deformation in the process of cutting stress, leading to the displacement of cutting piece, size beyond the tolerance range. 3, the choice of the cutting speed cutting speed is the cutting torch and workpiece during the process of the relative movement between speed. The appropriate cutting speed is the important condition of cutting surface roughness. Cutting speed depends on the material thickness, cutting current, gas type and flow rate, nozzle structure, the appropriate resistance, etc. Under the same power, improve the cutting speed causes a oblique cutting. Cutting, the cutting torch should be perpendicular to the surface, but in order to facilitate removal of slag, it can be slightly tilted, so in order to improve the productivity, cutting speed should be on the premise of ensuring penetration as large as possible. 4, cutting sequence influence cutting machine cutting order, cutting sequence refers to cutting the steel plate in turn on a few sets of nested components of the order. Generally should follow 'after the first, after the first small big' principle: the first cutting workpiece contour or nested within, outline of the parts, and then cut the outline; Cutting small parts first, and then cut big parts. Otherwise, in the sheet metal cutting, contour or other small parts deformation, lead to scrap processing parts.
