Focus on researching,Elaborately making, seeking high quality development.
When the main surface of parts with complex structure and shape is composed of complex curves and surfaces, multi-coordinate linkage processing is needed, which is difficult or impossible to complete on ordinary machine tools. NC machining equipment is the most effective equipment for processing such parts. Common typical parts are cam type, integral impeller type and die type.
What are the main processing objects of computer gong processing? Let***9;s get to know with Huacheng below.
1、When the main surface of parts with complex structure and shape is composed of complex curves and surfaces, multi-coordinate linkage processing is needed, which is difficult or impossible to complete on ordinary machine tools. NC machining equipment is the most effective equipment for processing such parts. Common typical parts are cam type, integral impeller type and die type.
1) Cam parts have various curved disc cams, cylindrical cams, conical cams and end cams. According to the complexity of the cam surface, a three-axis, four-axis or five-axis machining center can be selected.
2) Integral impeller is commonly used in compressor of aeroengine, air compressor, underwater propeller of ship and so on. It not only has the characteristics of general surface processing, but also has many special processing difficulties, such as narrow passage, easy tool to bend with the machined surface and adjacent curves.
2. The NC center of parts with both plane and hole system has automatic tool changing device. In one installation, milling of the upper plane of parts, drilling, boring, reaming, milling and tapping of threads can be completed. The parts processed can be on one plane or on different planes. Pentahedral Machining Center can be installed at one time to complete the processing of five surfaces except the clamping surface. Therefore, the parts with both plane and hole system are the preferred processing objects of computer gongs, such parts as box parts and plate, sleeve and plate parts are common.
1) Disc, sleeve and plate. There are planes, curved surfaces and holes on the end surface of the parts, and some radial holes are often distributed in the radial direction. Vertical processing equipment should be selected for plate, sleeve and plate parts whose processing parts are concentrated on a single end face. Horizontal processing equipment should be selected for parts whose processing parts are not located on the same direction surface.
2) Box-type parts are several common box-type parts. Box-type parts generally need multi-position hole system and plane processing, which requires high accuracy, especially the shape accuracy and position accuracy. Usually, it needs more cutting tools after milling, drilling, expanding, boring, reaming, countersunk, tapping threads, and so on. It is difficult to process on ordinary machine tools, with more tooling sets, multiple fixtures and alignment, more manual measurements and less accuracy. Guarantee. The last installation in the center can complete 60%-95% of the process content of ordinary machine tools. The parts have good consistency in accuracy, stable quality and short production cycle.
