Six issues that need attention in the processing of hydraulic parts

Count the problems that should be paid attention to in the processing of turning skills: the processing skills of CNC lathes are similar to those of general lathes, but because the CNC lathe is a clamping, the hydraulic parts are automatically processed in succession to complete all the turning processes, so you should pay attention to the following Aspects.

1. Reasonably select cutting amount.

2. Reasonable selection of tools:

(1) When roughing, choose high-strength and durable tools to meet the requirements of large-back tooling and large feed when roughing.

(2) When finishing turning, choose high-precision and durable tools to ensure the requirements of machining accuracy.

(3) In order to reduce the time for tool change and facilitate tool setting, machine clamped knives and machine clamped blades should be used as much as possible.

3. Reasonable selection of fixtures:

(1) Try to use general fixtures to clamp the workpiece, and prevent the use of special fixtures for hydraulic motor accessories;

(2) The positioning datums of the parts overlap to reduce positioning errors.

4. Determine the processing path: The processing path is the movement track and direction of the tool relative to the part during the processing of the index-controlled machine tool.

(1) It should be able to ensure the processing accuracy and surface roughness requirements;

(2) The machining path should be shortened as much as possible to reduce the time when the tool is empty. Rotor pump

5. The connection between the processing route and the machining allowance: At present, for the parts of rotary drilling rigs, when the CNC lathe has not yet reached the popular use, it is generally necessary to put too much allowance on the blank, especially for those rich in forging and casting hard skin. The remaining tissue is processed on a general lathe. If you must use a CNC lathe to process, you need to pay attention to the sensitive organization of the program.

6. The key points of the fixture device: Now the connection between the hydraulic chuck and the hydraulic clamping cylinder is completed by a tie rod, as shown in Figure 1. The key points of hydraulic chuck clamping are as follows: first use a moving hand to remove the nut on the hydraulic cylinder, rotate the excavator parts to remove the pull tube, and pull it out from the back of the main shaft, and then use the moving hand to remove the chuck fixing screw to unload. Lower the chuck.
