Dongguan precision electronic technology co. , LTD. , founded in 2008, is located in dongguan city, guangdong province shatian mori chau village culture around the team after the ferry road, is a precision stamping parts processing.
Professional production and processing precision shrapnel, hardware terminal, all kinds of hardware components.
The company has all kinds of advanced automated machinery equipment and product testing equipment, technical strength thick, male in the production of hardware small precision parts production has a solid strength.
Today the author to reveal precision stamping aperture, stamping factory is how to measure!
Aperture pass check gauge measuring way of is minimum, so we do with calipers measurement record general can record the minimum (
Rule out a small value, for example the error of the measurement error)
，（
Do not rule out in special circumstances)
Record the maximum and average no practical significance, for measuring the size of the aperture in every direction difference, should be recorded into the form tolerance of roundness, rather than the aperture.
If is surveying and mapping, and in the absence of any size can be reference, we should be subject to the section, not only by the average, for example, we measured the minimum may be the result of the punch somewhere wear, cross section of light with minimal at this time, so it is no meaning to the minimum.
In general the punch wear is caused by punching smaller (
Special-shaped hole should be concrete analysis)
So at the time of surveying and mapping is the maximum, cross section quality and don't forget, because made in punch time is a basic size of aperture + deviation within the allowed maximum value multiplied by zero.
5 to 0.
, 75, in order to leave wear after a period of time the use of punching smaller, but as long as the cross section quality will get by, then its value in the tolerance range, still take the maximum is correct at this time.
（
With should be ruled out too much value on the thickness direction deformation factors such as tilted hole, especially sheet)
。
Precision metal stamping parts supply, will pass strict quality control testing, make the product quality guaranteed.
Win the trust of customers!
