Relative to the ordinary lathe, CNC machining CNC milling machine with constant line speed drilling effect, whether for the interior hole or not straight through the inner hole can be processed with the same angular speed, that is, to ensure that the surface surface roughness value is common and relatively small. And the ordinary lathe is stable speed ratio, straight cutting parameters are not the same. Under the condition that the raw materials, finishing capacity and the Angle of view of the CNC blade are certain, the roughness of the outer surface depends on the cutting dosage and the cutting speed.
When CNC machining surfaces with different surface roughness, small super speed is used for those with small surface roughness, while large knife rate is used for those with large surface roughness. The plasticity is very good, which cannot be guaranteed by ordinary lathes. Wheel gallery posture jumbled parts.
Random plane curve can use parallel line or arc to close, CNC machining with arc tool radius compensation effect, can process a variety of miscellaneous wheel gallery parts. The use of CNC machining is necessary for operators to use carefully.
Metal parts processing key to fine turning, fine boring, fine milling, fine polishing and grinding and other processing technology.
1, CNC turning and fine boring: most of the high precision light aluminum alloy (aluminum or magnesium, etc.) parts of quadcopter are processed by this method. Generally, pure natural polysilicon diamond stone, the arc half meridian of the edge is less than 0.1μm. The precision of 1μm and the roughness of the surface with the mean aspect ratio less than 0.2μm can be obtained by the edge machining of a high-precision lathe, and the coordinate accuracy reaches +2μm.
2, finishing milling: used for precision machining posture jumbled aluminum or beryllium aluminum alloy parts. High accuracy of mutual parts can be obtained by the precision of slide rail and spindle bearing of CNC lathe. Precision mirror glass can be obtained by high-speed milling with a carefully milled stone knife.
3, CNC throwing: used to process shaft or hole parts. Most of these parts are made of hardened steel and have very high strength. Most high precision grinding machine spindle adopts negative pressure or dynamic pressure liquid rolling bearings to ensure high stability. The cutting limit accuracy is not only affected by the bending stiffness of lathe spindle and bed body, but also related to the selection and balance of sand wheel and the precision machining accuracy of the central hole of steel parts. A standard accuracy of 1μm and a irroundness of 0.5 μm can be obtained by fine casting.
4. CNC Milling: the basic principle of mutual grinding of matching parts is used to select and process the protruding position of the arc on the processed surface. The direct warp, cutting speed and drilling heat can be precisely controlled, so it is a machining method to obtain Z multi precision in fine machining technology. The hydraulic press or pneumatic mating parts of the high precision servo motor components of the quadcopter, and the rolling bearing parts of the dynamic pressure yo-yo motor are processed by this method to achieve the precision of 0. 1 to 001um and the external economic unsmoothness of 0.005μm.
Asset Metal technology focuses on metal process solutions, which are widely used in toys, electronics, intelligent components, unmanned aircraft and vehicles.
