Therefore, the current domestic mold industry is generally the first EDM and semi-finishing, the final polishing using ultrasonic finishing. Characteristics apply to the processing of hard brittle materials (especially the non-conductive hard and brittle materials), such as glass, quartz, ceramics, precious stones, diamonds, a variety of semiconductor materials, hardened steel, alloy steel and so on. Can be made the tool of complex shape than workpiece soft materials. Removal of the allowance is to rely on abrasive instantaneous local impact of the tool on the workpiece surface macro forces small, heat-affected small and does not cause deformation and burn, and therefore suitable for thin wall parts and the narrow groove of the workpiece, holes. The technology of green laser pointer will be discussed during the meeting.
The basic principles of rapid prototyping technology. Rapid prototyping technology is a general term for the principle of discrete layered production prototype, the principle is: the accumulation of raw materials → 3D CAD models → layered discrete → discrete plane geometry layer by layer processing to generate a solid model. The technology of computer technology, laser processing technology, new materials technology, relying on the CAD software in the computer to create a three-dimensional solid model, and cut into a series of plane geometry, in order to control the laser beam scanning direction and speed, means of using bonding, sintering, polymerization or chemical reaction layer selective processing of raw materials, to rapid accumulation of production of the product solid model. Modulation of laser beam of usa green laser pointer can be achieved to get the expected picture. The production requirement of green laser pointer should be strictly obeyed.
Processing characteristics of rapid prototyping technology. Rapid prototyping technology breakthrough in the traditional parts of the rough → cutting → product "processing mode, and create the parts do not have the tool to make the first of its kind, is a thin layer of an unprecedented superposition processing method. Compared to traditional machining methods, rapid prototyping process has the following advantages: You can quickly create a free surface and a more complex form part of new products such as parts of the groove, the shroud and the hollow part of the greatly reduced development costs and development cycle. Is a non-contact processing, no machine cutting tools and fixtures necessary, no tool wear and cutting force of impact. The quality feedback of green laser pointer will be help the engineer with improving the quality of green laser pointer .
No vibration, noise, and cutting waste. Can be realized fully automated production at night. Processing efficiency, and can quickly create a solid model and mold.

The lifetime of green laser pointer will be longer if green laser pointer is used properly.
Plasma arc cutting is the use of high-temperature plasma arc heat the metal of the workpiece incision partial melting (and evaporation), and by high-speed plasma momentum to rule out a processing method for the molten metal to form the incision. Plasma cutting is developed to now can be the working gas (working gas plasma arc conductive medium, but also to bring a hot body, but also exclude the incision in the molten metal) on the plasma arc cutting features and cutting quality, the speed has significant impact. The plasma arc working gas of argon, hydrogen, nitrogen, oxygen, air, water vapor and gas mixture. The specific requirement of green laser pointer should be carefully obeyed.
