Several close to the lathe turning technology processing should pay attention to the problem: CNC lathe processing technology and ordinary lathe processing technology is similar, but because the CNC lathe is a clamping, hydraulic parts continuous automatic processing to complete all the turning process, and should pay attention to the following aspects.
1. Reasonable selection of cutting parameters.2. Reasonable tool selection:(1) thick car, to choose high strength, durability of good tool, in order to meet the thick car when the large back feed, large feed requirements.(2) when finishing the car, choose the tool with high precision and good durability to ensure the machining accuracy.(3) to reduce the time of tool change and facilitate tool alignment, machine clamping knives and machine clamping blades should be used as far as possible.3. Reasonable selection of fixtures:(1) try to choose general fixture to clamping workpiece, hydraulic motor parts to avoid the use of special fixture;(2) the positioning datum of parts overlaps to reduce positioning error.4. Determine the machining path: the machining path is the track and direction of the cutter relative to the parts in the process of exponentially controlled machine tool machining.(1) the machining accuracy and rough surface requirements shall be guaranteed;(2) the machining road should be shortened as far as possible to reduce the empty travel time of the tool. Rotor pump5. The connection between machining road and machining allowance: at present, under the condition that the accessories of rotary drilling machine have not been widely used by CNC lathe, the excessive allowance on the blank, especially the allowance rich in forging and casting hard cortex, should be arranged to be processed on the general lathe. If you must use CNC lathe processing, you need to pay attention to the flexible arrangement of the program.6. Key to fixture installation: at present, the connection between hydraulic chuck and hydraulic clamping cylinder is realized by pulling rod
