Machining Precautions

Machining Precautions

Machining currently developing more and more rapidly, then we know Precautions machining non-standard parts processing What do? Following on from the Notes tell your machining:

1, during the time of machining must be accurate positioning, can not have vibration, to prevent operator error;
2, machine construction must be reasonable, arranged handle, hand wheel, the button according to regulations. Start button to be installed in the chassis to prevent accidental touches, you can add a grommet. To prevent the hand wheel, turn the handle with the shaft moving wounding Ball check, you need to install the automatic prolapse means;
3, in order to avoid operating member incoordination and multiplayer operating uncoordinated happens, you should install interlock;
4, to facilitate the operation, to reduce back and forth, eliminating bending, toes and other necessary actions;
5, the direction of movement of the operating member shall comply with the requirements, and marked with the symbol.
What is the precision machinery testing it?
Precision mechanical testing is an important precision machinery inside a non-standard parts processing technology currently mainly of European and American technology, for example in Germany and the United States AMT VDI like. But no matter what technology is the same principle too, their measurement methods and techniques more similar. Determination of test machine tool positioning accuracy, there are two common standards: · Germany VDI / DGQ3441 standard (machine running precision and positioning precision approach count). · AMT American Standard (American Association for the development of machinery production technology). Two standard pack survey values are appropriate and that the use of mathematical and statistical approach. That is a direction parallel to the axis of the axis of a survey targeting select several arbitrary points (general 5 to 15), and then repeatedly positioned (general 5 to 13 times) for each point repeat positioning purposes. Unidirectional approach can locate the point to be approached from two directions goodbye, then for the purposes of the survey the numerical count disposal, find mathematics uniform value. Continue to move forward uniformly determined deviation, standard deviation, degree of scatter. Representative repeat positioning precision of spreading it evenly, and together constitute a positioning accuracy deviation, sum of the two is possible when positioned between two arbitrary achieve maximum positioning error.
To sum up: Precision mechanical testing in precision machining which is one important step, only do precision machinery inspection work in order to make better and more sophisticated precision parts.
On the technical precision parts processing machinery
Learn the technology is promising, like precision components processing machinery, as in high-end manufacturing such a respected under it is a very promising work, but it has higher requirements of the operator, precision machinery parts processing the operator is required to make a smaller error and mechanical machinery.
It is important to note that the default precision machinery, in other words higher than the preset objects precision mechanical system, the default article also is used in high-precision spectrograph precise mechanical technology professional foster Objective: Cultivation master the basic theory and professional knowledge and precision machinery spectrograph, something precise spectrograph with mechanical preset production, as well as surveying and curb high-level protection and management of technical facilities and specialized customer only. Obviously precision parts processing machinery to better development requires high-quality personnel, and high-precision mechanical equipment, precision machining parts to make more sophisticated machinery.
Details CNC machining of precision parts
CNC Precision Machining center equipment from lightweight machine body, high density AC servo motor, high-precision magnetic encoder, servo unit and motion control system 5 major components. Its notable feature is to have compact size, with in addition to the automatic tool performance and full functionality of conventional CNC machining centers.
When CNC Precision Machining center power can not be turned on if the power indicator (green) does not light; fuses F1 power unit, F2 has blown; this is because high input voltage causes, the power supply unit itself or damaged components ; there are two lights, one is the power indicator is green power supply unit CNC machining centers; one is the power warning light is red, here said power supply unit includes a power input unit and the power supply control section;
CNC Precision Machining center input voltage is low. Check the power supply unit into the voltage, the voltage value of allowable AC 200V + 10%, bad 50HZ ± 1HZ, power supply unit, there are dollars damage, power indicator light, non-standard parts processing warning lights disappeared, but the power does not come on , then because the power is turned on (ON) the condition is not satisfied.

CNC precision machining parts in order to improve cutting performance, at home and abroad have developed a special EDM copper wire, which is plenty of brass wire inside and outside plated zinc alloy lower melting point, in the discharge of fire have a greater vaporization explosion force, higher cutting speed wire cutting, specifications for (0.10 ~ 0.30) mm; Similarly, in the cutting slot or require subtle rounded small, tungsten or molybdenum wire can be used, the smallest diameter of up to 0.02 ~ 0.06mm
