The color of portable cell phone jammer is classified according to the wavelength

In most cases, the shape of the base surface line cutting machining prior to the processing of already ready.
 The choice of processing methods to determine the processing method according to the processing object, accuracy and surface roughness requirements and machine performance. EDM machining methods of processing usually have the following. Electrode forming method (1) single tool electrode forming method of a single tool with a tool electrode to complete the mold cavity roughing, processing and finishing. Single-electrode level processing of the dynamic method, the tool electrode a single fixture positioning.
The colors of portable cell phone jammer include red, green and purple and so on.   to avoid positioning errors due to repeated clamping. For the angular high cavity, machining accuracy is not guaranteed. (2) multi-electrode replacement electrode replacement method using several different sizes of the tool electrode to complete a cavity of the coarse, medium and finishing. First used in the processing of the rough electrode erosion in addition to a lot of metal, and then replace the electrode in, finishing; for high precision machining of the cavity, and often require more electrodes to the intensive cavity.
This method has the advantage of profiling accuracy, especially at sharp corners, narrow multi-cavity mold processing. The disadvantage is the need to create multiple electrode repeat manufacturing precision electrode requirements, and to consider the repeated positioning accuracy when the electrode replacement. The color of portable cell phone jammer is classified according to the wavelength.  (3) decomposition of the electrode machining method to decompose the electrode machining method is based on the cavity geometry, the electrode broken down into main cavity electrode and vice-cavity electrode, namely manufacturing.
 First electrode machining of the main cavity of the main cavity, electrode machining Vice cavity with sharp corners, narrow parts of the sub cavity. The advantages of this method according to the Lord, vice cavity different processing conditions, different processing criteria, help to improve the processing speed and improve the quality of the machined surface, but can also simplify the electrode manufacture, easy electrode dressing. The disadvantage is that precise positioning of the main cavity and vice cavity is more difficult to solve.
and access to high-frequency pulse power on the electrode and the workpiece, the processing of continuous and periodic spark discharge galvanic corrosion of the workpiece. 1 - electrode; 2 - spindle head; 3 - Block the spindle head; 4 - pulse power; 5 - storage tanks; - oil cup; 7 - workpiece; 8 - oil pump; 9 - tank; 10 - filter; - pipeline; - return line in Figure 6.35 spark molding machine is generally the first forming tool electrode forming process schematic spark,  If the color of an object and the laser of a portable cell phone jammer is the same, the absorption of energy is very low.
