The performance of green laser pointer has been accepted by the quality group.
Laser quenching is rapid heating, since the shock cooling no furnace insulation and cooling liquid quenching, a non-polluting green heat treatment process can be easy to implement uniform hardening of the large surface of the mold. Fast laser heating, the heat affected zone is small, the surface scan heating quenching, ie, instantaneous local heating quenching deformation is small, so the mold processing. As the laser beam divergence angle is small, has a good point, accurate local quenching by the optical system of the mold surface. Laser surface hardening depth of hardened layer is generally 0.3 ~ 0.7mm, its application is subject to certain restrictions. The choice of process parameters affecting the quality of laser hardening process parameters is multifaceted. The expert has confirmed the performance of green laser pointer .Every three-in-one green laser pointer with wireless microphone is used in different classrooms
Laser power, scan speed, spot size, beam energy distribution, the light absorbing coating type and thickness. The key indicators to measure the quality of laser hardening the surface roughness of the hardened layer depth, width, hardness and hardened layer. The key relationships between the following points: laser unit time in the mold of the power density, will determine the effect of laser hardening. The workshop plans to perform the lean production for the new type of green laser pointer .
Within the range of 102 ~ 104W/cm2 s increased power density, scanning speed decreases, will allow the mold hardened layer depth, hardness and surface roughness of the hardened layer increases. If the power is too large, the scanning speed is too slow, that is too much power, exceeding the above range will cause the surface melting, burning; the contrary, the hardness and the depth of hardened layer will reach the technical requirements. Laser hardened layer width is determined by the spot size. Quenching of a large area must be multi-channel scanning. Broadband scanning narrowband scanning efficiency. The beam energy distribution of the hardened layer depth, width and organizations uniformity. It is determined by the beam pattern and the optical system. Typically, according to the actual situation of the equipment should be adjusted to the best state, in order to ensure the uniformity of the hardened layer.
