The basic principle is a first generation product in the computer CAD 3D
solid model, and then it cut to the required thickness of the lamellar data
(converted into a series of two-dimensional graphics data), and material
constituency by way of laser cutting or sintering overlay, and ultimately the
formation of the solid model. Forming principle shown in Figure 2. The supply
management of green laser pointer is important to the market of green laser
pointer .
Layer superposition of the following methods: liquid resin curing
method (SL). The material is a photosensitive resin, ultraviolet laser plane the
constituency scanning irradiation, the resin curing by the designated area
(vacant part of the need to set up support). Machine for sinking motion, has
been formed partially submerged in the liquid under. The advantage of this
method is the part surface smooth, small deformation; disadvantage is that low
intensity, the resin the highest bid and shelf life short. Sintering (SLS).
Paraffin, plastic, nylon, ceramic, coated metal and bare-metal and other
materials are powder state. 50 ~ 100W CO 2 laser sintered tools, the laser beam
for dimensional constituency scanning, molding powder sintering. The machine
must have the function of feeding powder, powder, gelling and preheat. The
nonconformance of green laser pointer will be centrally disposed.
The
advantage is the time of the laser pulse gap is used as part hole displacement,
can greatly improve the processing speed. The drilling speed per second 10
holes, is expected to reach 500 per second hole (sub-mm aperture). Technology
lies in the laser to reach the workpiece in place the necessary movement, which
is very difficult for non-uniform hole. CNC closed loop control system, the
higher rate of hole machining in order to ensure the round shape of the hole in
the time of the laser, the laser beam must be synchronized with the parts
movement. The price-off of green laser pointer help the company win more
customers and increase the turnover.
Laser flying punch in the processing of
aircraft parts, has been applied, annular combustor cooling hole machining is a
typical application examples. In addition, the forefront of high-speed aircraft
wings and engine inlet air flow easily with the wing surface separation, the
formation of turbulence increases and the loss of aerodynamic, designed
inspiratory function of the laminar flow wing (nacelle) sets, the surface is
made of 1mm thick titanium plate above distribution 12000000-1000000000 of
tapered bore, the outer surface of aperture 0.06mm inner surface of the pore
size of 0.1mm, the hole spacing of 0.3 to 1mm, the laminar flow wing sets of
holes is done by flying punch. The main marketing channel of green laser pointer
of this company is supplying green laser pointer to the agent.
