Common surface treatment for precision parts processing in Shenzhen: blackening, anodizing, chromium plating, nickel plating, titanium plating, zinc plating, electropolishing, passivation, PVD film plating, Ganak, etc. The processing technology (heat treatment process) of precision parts and components, and determine the machine tool, clamping method, measurement method, machining allowance, cutting amount and man hour quota used in each process. Fill all contents in the process procedure table, which is the machining process procedure. Check whether the drawings of parts are complete and correct, and analyze whether the accuracy, surface integrity, technical requirements, etc. of the main surfaces of parts can be met under the existing production conditions.
Specify the processing content and requirements; Determine the processing scheme; Select suitable CNC machine tools; Select or design tools and fixtures; Determine a reasonable tool path and select a reasonable cutting parameters. On the NC machine tool with the graphic simulation display function, the program can be checked by displaying the tool path or simulating the cutting process of the tool to the workpiece.
For parts with complex shape and high requirements, aluminum, plastic or paraffin and other free cutting materials can also be used for test cutting to inspect the procedure. By checking the test piece, we can not only confirm whether the program is correct, but also know whether the machining accuracy meets the requirements. For workshops that often process titanium alloy parts (especially noble large aviation parts).
The 50% increase in productivity is worth his investment in purchasing special tool chucks and machine tools with high-pressure cooling systems installed. With the extensive application of high-tech materials, combined with the existing equipment and technology, the existing tool materials and new processing methods are fully used in mechanical processing.
For difficult to machine materials such as stainless steel and heat-resistant alloy, coolant or blade with good rigidity can be used. The relationship between the feed condition and the wear behind the tool occurs in a small range. But the feed rate is large, the cutting temperature rises, and the rear wear is large. The specific cutting speed has little influence on the tool.
