Causes and solutions of parts deformation and corner of laser cutting machine

2021-07-26

Why does the numerical control laser cutter cut a part to be able to deform sometimes? First, let's check to see if it's caused by the dimming. The second is to analyze which raw materials are used to cut, raw materials reflective characteristics and metal characteristics may affect the cutting effect. If the cutting metal plate, laser cutting belongs to thermal cutting, thermal cutting will certainly deformation. Compared to flame cutters and plasma cutting, the distortion is relatively small. But it's still deformed. The deformation is closely related to the cutting material, the shape of the part, the cutting thickness and the laser processing technology. The shape of the part largely determines the size of the deformation. For example, if you cut a square, the thermal deformation will not be too large. But if you cut a long, narrow rectangle (10 * 2000 mm) , the distortion will be very large. The reason for the deformation is uneven heating, leading to thermal expansion and cold contraction, leading to switch changes. Laser cutting machine why there is corner how to deal with? Because my laser cutter is servo control Motor, motor control Screw. In this case, the MEC Laser Cutting Machine manufacturers believe that the end point and the starting point can not return to the same position, this may be a drawing problem, may also be a machine structure. There are three ways to do this. 1. Turn acceleration and power should be adjusted well 2. The graphics are guaranteed to be round. 3. Check that your mechanical structure is accurate enough. 22083085
