First, surface smoothness: stainless steel precision tubes used in furniture and bathroom have high requirements for surface smoothness, using mechanical polishing or electrochemical polishing method, surface scratches, rust and sand holes, high precision needs to achieve 6K mirror effect, finish Ra value of about 0.8μm, and can not be polished excessively resulting in uneven wall thickness. Weld residual high is more difficult to deal with, in addition to testing polishing technology, welding molding between steel strip and steel strip coincidence precision directly affects the weld residual high, precision stainless steel welded pipe in the process of welding molding using high-end equipment, plus later precision polishing, weld almost zero touch.
Second, perpendicularity: The electronic and electrical shell has certain requirements on the verticality of the welded pipe. The straightening and correcting control parameters are given by the computer according to the bending test data of the pipe and processed by the measurement and control system. Then the servo speed regulating motor is controlled by PLC to drive the rotating center, so that the maximum bending point of the workpiece is vertically upward. Complete the alignment cycle.
In addition to the straightening process, the cutting process will also affect the verticality. When the hardness of the stainless steel workpiece is low and the wall thickness is small, it is easy to bend and tilt the pipe during the cutting process. Our Gang manufacturers will choose the appropriate hardness of the material, and the use of laser cutting process, the operation of the workpiece zero contact, to ensure the verticality of precision stainless steel pipe.
Third, ellipticity: some special components of mechanical equipment need to be punched, drilled or slotted on the pipe body, which is easy to cause the pipe body depression and pipe mouth deformation. The laser process can avoid the impact force caused by deformation of the pipe mouth, and when punching processing, the mold through precision customization, no matter the shape or size are worn, to ensure the high consistency of the stainless steel pipe and the mold, to ensure that the ellipse is controlled at a very low value.
