The engineer will revise the technical report of cell phone jammer
The radio frequency technology of cell phone jammer is commonly used in the market. No stamping device for laser cutting machine, there are two basic methods of perforation: blast hole: (Blast drilling), materials by continuous laser irradiation to form a pit in the center, then the laser beam coaxial with the oxygen flow soon remove the molten material to form a hole. Generally the size and thickness of the hole, blasting perforation thickness of half the average diameter, so the thicker the plate the larger diameter hole blasting, and not round, not in the higher parts to use (such as oil sieve tube seam ), can only be used on waste. Furthermore, since the oxygen pressure used in piercing and cutting the same time, a large splash. Pulse perforation: (Pulse drilling) use of high peak power pulsed laser to melt or vaporize a small amount of material, commonly used as an auxiliary air or nitrogen gas to reduce oxidation of the hole due to heat expansion, the gas pressure when the oxygen pressure than cutting small. The paragraph will state the difference between technology and RF technology of cell phone jammer .
Each laser pulse produced only a small spray particles, gradually in-depth, so the plate perforation takes a few seconds. Once the piercing done, immediately replace the oxygen assist gas for cutting. This smaller diameter hole, the hole quality is better than blasting perforation. This not only to be used in lasers with higher output power; more importantly, when time and space characteristics of the beam, it is generally transverse flow CO2 laser cutting laser can not meet the requirements. In addition, the pulse must have perforated more reliable pneumatic control systems, in order to achieve gas species, gas pressure control switch and perforation. In the case of pulsed perforated, in order to obtain high-quality cut, the rest from the workpiece to the workpiece constant pulse perforated continuous cutting technology should be to focus attention on the transition. In theory, usually to change the acceleration section of the cutting conditions: such as focal length, nozzle position, gas pressure, but in fact because of the time is too short to change the above conditions is unlikely. The emitter of cell phone jammer should stay aligned with the receiver of cell phone jammer .
