It is to guide the production of the new type of green laser pointer

Warm-up can reduce the temperature gradient of the welding region, thereby reducing the thermal fracture. But the warm-up will also reduce the mechanical properties of the parent material, and can not be applied in the parent material is fixed. Using the appropriate form of joint compatibility better fill the alloy can reduce the thermal fracture appears. Aluminum alloy surface should be cleaned before welding, to remove oxides, grease and loose impurities. The surface cleaning is very important, because the welding of the aluminum alloy, the excess hydrogen will cause a bubble, too much oxygen in the formation of scum. Welding underwater welding under extreme environment to work in factories and repair shops can control the environment, some of the welding process can be carried out in a variety of environments such as outdoors, underwater, (such as space) vacuum. The technical personnel shall provide more advices of  green laser pointer .
Dedicated lathe the processability ф1000m length 14m less than the parts. All structural parts using CNC cutting cutting edge milling machine to be assembled structures reinforcement to the underside of the knife check to increase the contact surface of the assembled parts to ensure a degree of parallelism, an increase of the rigidity and strength of the overall structure. Hydraulic support structure used in all our company developed a special six-axis boring machine and four-axis gantry boring machine for the overall processing and reliable way to ensure the structural hole between the position requirements and consistency of the structure size to solve the hole axial and position tolerance requirements of the problem, ensure R0.5 and R1mm, concentricity requirements, completely solved the structure of the assembly quality and interchangeability requirements. It is to guide the production of the new type of green laser pointer .
