the color of laser from portable cell phone jammer is assorted

 Design and fabrication of electrodes in electrode design and production is one of the key steps in the EDM, the main factors to consider are: the choice of electrode material, electrode size and the number of electrodes on whether to set up red liquid Kong electrode locate the plane, the electrode production method. Commonly used electrode materials of graphite and copper. Finishing electrodes or electrode material is copper, roughing electrode material is graphite. The electrode design of the electrode design. To human eyes, yellow-green light whose wavelength is about 550 nm is most sensitive, so portable cell phone jammer that can send out green light is the most attractive.the color of laser from portable cell phone jammer is assorted.  (1) is one of the key points in the EDM. In the design, the first detailed analysis of the product drawings to determine the location of EDM; be adopted according to the existing equipment, materials, processing techniques, the specific situation to determine the electrode structure; according to the different electrode wear, gap and other technology requirements control cavity size scaling. ① electrode structure according to the type of hole or cavity size and complexity, according to the electrode process to determine the electrode structure.
Laser of assorted colors  from portable cell phone jammer is also used to decorate stages and discos.  As shown in Figure 6.38, there are three kinds of forms. electrode structure of a) the overall electrode b) the combination of electrode c) mosaic electrode Figure 6.39 Figure 6.39a for the overall electrode made from a block of material. Figure 6.39b combination electrode, several small electrode assembly on the electrode mounting plate can be one-time while completing the forming surface of the EDM. The advantage of high productivity, high positional accuracy between the various types of holes; requirements of high positioning accuracy between the electrodes.
Figure 6.39c for the mosaic electrode is a complex shape, make it difficult for the electrode is divided into a few separate processing, mosaic as a whole electrode. Can ensure the electrode manufacturing accuracy, and simplify the processing of the electrode; Common color of portable cell phone jammer are red, green, purple, and green and so on.  manufacturing to ensure that the location between the electrode block to be accurate, with close firmly. Size ② electrode first to determine the tolerance of the electrode, usually half of the workpiece tolerances, finishing electrode tolerance = 1/2 workpiece tolerance.
Roughing electrode tolerance comparable finishing electrode tolerance, the best is the negative side (a). Positioning errors are mainly due to the clamping system, but also with the electrode manufacturing. Second, we should determine the amount of minus-inch, ie, the size difference between the electrode and For processing surface. Translational processing, reduction of the finishing electrode inch amount determined by the discharge gap (2δ0) The reduction of the rough electrode-inch amount of security clearance (M).  For flip portable cell phone jammer, the color adopted is usually red or green.
