The processing process of Special Machine for Servo Gate Valve is similar to that of ordinary lathe, but because the Special Machine for Servo Gate Valve is a one-time clamping, continuous automatic processing to complete all turning processes. Therefore, attention should be paid to the following aspects:
one Reasonable selection of cutting parameters
The selection of cutting parameters (ap, f, v) is reasonable, which plays a very important role in giving full play to the potential of the machine tool and the cutting performance of the tool, and achieving high quality, high yield, low cost and safe operation.
Rough turning, first consider choosing a as large as possible back cutting amount ap, followed by choosing a larger feed amount f, 朂 to determine a suitable cutting speed v. Increasing the amount of back cutting ap can reduce the number of cutting times, increasing the amount of feed f is conducive to chip breaking, so according to the above principles to choose the rough cutting amount to improve production efficiency, reduce tool consumption, reduce processing costs is beneficial.
When finishing, the processing accuracy and surface roughness requirements are high, and the processing allowance is small and uniform, so when selecting the cutting amount of finishing, we should focus on how to ensure the processing quality, and on this basis, improve the productivity as much as possible. Therefore, small (but not too small) back cutting amount ap and feed amount f should be selected when fine turning, and tool materials with high cutting performance and reasonable geometric parameters should be selected to increase the cutting speed v as much as possible. 2. Reasonable choice of tool
1) When rough, it is necessary to choose a tool with high strength and good durability in order to meet the requirements of large back cutting quantity and large feed quantity when rough turning;
2) When finishing, it is necessary to choose a tool with high precision and good durability to ensure the requirements of processing accuracy. ;
3) In order to reduce the tool change time and facilitate the tool, the machine clamp knife and the machine clamp blade should be used as far as possible.
3. Reasonable selection of fixture
1) Try to use general fixture to clamp the workpiece, avoid using special fixture;
2) The positioning reference of the parts is overlapped to reduce positioning errors.
4. Determine the processing route
The processing route is the movement path and direction of the tool relative to the part during the processing of the exponential control machine tool:
1) Should be able to ensure the processing accuracy and surface roughness requirements;
2) The processing route should be shortened as much as possible to reduce the empty travel time of the tool.
5. The connection between the processing route and the processing allowance
At present, under the condition that the Special Machine for Servo Gate Valve has not yet reached popular use, the excess margin on the blank should generally be arranged on the ordinary lathe processing, especially the margin containing forging and casting hard skin. If Special Machine for Servo Gate Valve must be used for processing, it is necessary to pay attention to the flexible arrangement of the program.
6. Fixture installation points
At present, the connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by the pull rod. The key points of the hydraulic chuck clamp are as follows: First remove the nut on the hydraulic cylinder with the lift hand, remove the pull pipe, and pull out from the rear end of the spindle, and then remove the chuck fixing screw with the lift hand, you can remove the chuck.
