All kinds of mechanical processing, do not understand machinery can also understand!

▲ Drilling process

When drilling on the drilling machine, generally, the drill should complete two movements at the same time: the main movement, that is, the rotary movement of the drill around the axis (cutting movement); Auxiliary movement, that is, the drill moves straightly towards the workpiece along the axis direction (feed movement). When drilling, the processing quality is affected mainly due to the shortcomings of the drill structure. The processing accuracy is generally below IT10, and the surface roughness is Ra12.5 μ M, belonging to rough processing.

▲ Multi axis CNC machining

Multi axis NC machining can simultaneously control the linkage of more than 4 coordinate axes, and combine the functions of NC milling, NC boring, NC drilling, etc. After the workpiece is clamped once, it can perform multiple processes such as milling, boring, and drilling on the machining surface, effectively avoiding the positioning error caused by multiple installations, shortening the production cycle, and improving the processing 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 electro crystallization process. Its purpose is to change the surface properties of solid materials or make metal materials with specific composition and properties.

▲ Induction heating

Induction heating: the workpiece is placed in the inductor, which is generally a hollow copper tube that inputs medium frequency or high frequency alternating current (300-300000Hz or higher). The alternating magnetic field generates the induction current of the same frequency in the workpiece. The distribution of this induction current in the workpiece is uneven. It is strong on the surface, but weak inside, and close to zero at the center. With this skin effect, the workpiece surface can be heated rapidly. The surface temperature rises to 800-1000 ℃ within a few seconds, while the center temperature rises very little.

▲ Welding process

The basic working principle of electric welding is that after the 220V or 380V voltage is switched on, the voltage is reduced through 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 steel, while the welding rod melting makes the fusion between steel and steel higher.
