Precautions for the Continuity of Automatic Numerical Control Machine
Automatic CNC machine tools to solve the complex, sophisticated, small batch, multi-species of parts processing problems, is a flexible, high-performance automated machine tools, represents the modern machine tool control technology development, is a typical electromechanical Integrated products. CNC lathe processing technology and lathe processing technology is similar, but because the CNC lathe is a clamping, continuous automatic processing to complete all turning processes, so pay attention to the following aspects. In this case,
1. Reasonable choice cutting amount. In this case,
2.2. Reasonable choice of tools:
(1) roughing, the election of high strength, durability, good tool in order to meet the rough back when the knife to eat a large amount of large feed requirements. (2) fine car, to select high precision, durability, good tool to ensure the accuracy of processing requirements. In this case,
(3) in order to reduce the tool change time and facilitate the knife, try to use the machine folder and machine folder blade. In this case,
3. Reasonable choice of fixture:
(1) try to use universal fixture clamping parts, to avoid the use of special fixtures;
(2) parts positioning reference coincidence, in order to reduce the positioning error. In this case,
4 to determine the processing line: processing line refers to the CNC machine tool processing, the relative movement of the tool path and direction. (1) to ensure that the processing accuracy and surface roughness requirements;
(2) to shorten the processing route, to reduce the tool air travel time. Rotor pumps
5. Processing line and the processing margin of contact: At present, the CNC lathe has not yet reached the conditions of universal use, the general surplus on the blank too much, especially with forging, cast hard skin margin arranged in the ordinary lathe On the processing. If you must use CNC lathe processing, you need to pay attention to the flexibility of the program. In this case,
6. Fixture installation points: the current hydraulic chuck and hydraulic clamping cylinder connection is achieved by the lever, hydraulic chuck clamping points are as follows: First, remove the hydraulic cylinder with a wrench nut, remove the tube, and from the Remove the chuck by removing the chuck fixing screw.
