Answer:
In ordinary parts and precision parts, more and more people will tend to choose the precision parts,it is also as a part of the machinery, precision parts how can be so popular? What are the benefits of precision parts processing?
Parts in the process of processing, due to the influence of various factors, easy to lead to its own will have certain defects, such as the appearance is not up to standard; Limited scope of use and so on. The existence of these defects is bound to bring some problems to the use of parts, in order to overcome these problems and give play to the unique value of parts, precision machining is the best choice.
The use of precision parts processing, not only can effectively improve the quality of materials, parts precision, play its function, but also can make the durability of parts greatly improved, to improve the quality of the whole machine. Precision machining is also beneficial to improve the dimensional accuracy of parts, so the most direct effect is to make parts interchangeability, and then increase the wear resistance and service life of parts.
It is because of all the advantages above, so precision parts processing will be so popular, equipment assembly can also have a more suitable field to be adopted, so that its value gets the ultimate play. From this point of view, we must pay attention to precision parts processing links.
After a variety of different parts processing we can get more suitable for their own parts, so in order to make these products better for their own service, play its most extreme value, so many people are not without precision machining this important link.
Answer:
Any parts in the processing of time is a precision requirement, if the detection of precision parts processing accuracy is found to be poor, such products are likely to become unqualified products. So for parts, why does its processing accuracy become worse?
The poor machining accuracy of parts is largely due to the failure of dynamic feed tracking error between axes during equipment installation and adjustment. Or because the machine wear, the machine tool shaft transmission chain has changed. In this case, it can be solved by readjusting and modifying the clearance compensation amount.
When the alarm is large, check whether the servo motor speed is too high; Position detection element is good; Position feedback cable connector is in good contact; Whether the corresponding analog output latch and gain potentiometer are good; Whether the corresponding servo drive device is normal, and timely maintenance.
Of course, if the machine tool movement overshoot will also cause parts processing accuracy is not good, such as adding and decelerating time is too short, can be appropriately extended speed change time; It may also be that the connection between the servo motor and the lead screw is loose or the rigidity is too poor, and the gain of the position ring can be appropriately reduced.
In addition, when the two axes of the parts processing equipment are linked, the machining accuracy of the parts will become worse under the influence of such factors as the axial deformation of the circle and the oblique ellipse error. The deformation may be caused by mechanical adjustment; For the oblique ellipse error, the position deviation value of each axis should be checked first. If the deviation is too large, the position ring gain can be adjusted to eliminate it.
Answer:
In order to improve the oxidation resistance of parts in precision parts processing, first of all to improve the cutting performance of materials, temperature control is a very key link; The second is aging treatment, the purpose is to eliminate the pressure, so as to obtain better performance; There is also low temperature heat treatment, for thin-walled and precision machined parts, there must be a stable heat treatment process to achieve the ideal goal.
In addition to heat treatment, reasonable arrangement of processing technology can also ensure the normal use of production tools and parts quality, so as to meet the requirements of accuracy and performance.
Answer:
First of all, precision parts processing fixture device must have the appropriate clamping force, the so-called appropriate refers to both ensure that the workpiece in the whole processing process its position is stable, small vibration, but also to make the workpiece does not produce too large clamping deformation.
Secondly, its process must be better, in order to better cooperate with the completion of precision parts processing. The complexity of clamping device is required to adapt to the production program. On the premise of ensuring production efficiency, its structure should be simple and easy to manufacture and maintenance.
There is good usability, the operation of the clamping device used in the processing of precision parts should be convenient, safe and labor-saving, and provide a stable foundation for the completion of the whole processing process. Referring to the above requirements, the current use is more inclined wedge, screw, eccentric and other parts of the combination of the clamping mechanism.
This kind of precision parts processing clamping device uses the inclined wedge as a force transmission element or clamping element. In the case of the direct use of the inclined wedge clamping, when the rising Angle of the inclined wedge is less than the sum of the friction Angle between the inclined wedge and the workpiece, the inclined wedge and the clamp, the self-locking will occur.
In order to ensure the reliability of self-locking, the inclined wedge of clamping device is driven by air pressure or hydraulic pressure device. At the same time, the design is also in line with the characteristics of simple structure, large increase ratio, good self-locking performance, so it is widely used in the process of precision parts processing.
Answer:
Experts of Kreis tells you because there are many parts in machinery and equipment are injection molded parts, so the precision parts processing can also be done through precision injection, only need to strictly control the material, equipment and mold, process the four basic factors, can make precision parts processing to achieve the desired effect, parts of the size tolerance, form tolerance and surface roughness meet the relevant requirements.
When injection molding is used for precision parts processing, engineering plastic materials should be selected first. The materials that can meet the requirements of precision injection molding should be those with high mechanical properties, stable size, good creep resistance and environmental stress cracking resistance. Secondly, suitable injection molding machine should be selected according to the selected plastic materials, finished product dimensional accuracy, piece weight, quality requirements and expected mold structure.
