▲ drilling process
When drilling on the drilling machine, generally, the drill should complete two movements at the same time: the main movement, i.e. the rotation movement of the drill about the axis (cutting movement); Auxiliary movement, i.e. the straight-line movement (feed movement) of the drill bit against the workpiece along the axis direction. During drilling, the machining quality is affected mainly due to the shortcomings of the drill bit structure. The machining accuracy is generally below it10 and the surface roughness is Ra12.5 μ M U.M, which belongs to rough processing.
▲ multi axis NC machining
Multi axis NC machining can control the linkage of more than four coordinate axes at the same time, and combine the functions of NC milling, NC boring and NC drilling. After the workpiece is clamped once, the machining surface can be processed in multiple processes such as milling, boring and drilling, which effectively avoids the positioning error caused by multiple installation, can shorten the production cycle and improve the machining accuracy.
▲ metal electrodeposition
The electrodeposition of metal is a process of forming a metal layer on the solid surface through the reduction reaction of metal ions on the cathode of the electrolytic cell and the electrocrystallization process. Its purpose is to change the surface properties of solid materials or to produce metal materials with specific compositions and properties.
▲ induction heating
Induction heating: the workpiece is placed in the inductor. The inductor is generally a hollow copper tube that inputs medium frequency or high-frequency alternating current (300-300000 Hz or higher). The alternating magnetic field generates induced current of the same frequency in the workpiece. The induced current is uneven in the distribution of the workpiece. It is strong on the surface, but weak in the interior, and close to zero in the center. By using this skin effect, the surface of the workpiece can be rapidly heated, and the surface temperature rises to 800-1000 ℃ within a few seconds, while the temperature in the center rises very little.
▲ welding process
The basic working principle of electric welding is that after the voltage of 220V or 380V is connected, the voltage is reduced by the pressure reducer in the electric welding machine, the current is increased, and the electric energy generates huge arc heat to melt the welding rod and the steel, and the fusion of the welding rod and the steel is higher.
