Inspection method for machining of precision mechanical parts

When testing the processing of precision machinery parts in Changzhou, it is necessary to know the inspection system of the processing of precision machinery parts, as well as the detection skills of the processing of precision machinery parts. What are the detection skills of precision machinery parts Woolen cloth?

1. Measurement techniques for outer diameter

When measuring the outer diameter, it is necessary to measure and record at two parts in the circumferential direction. When the length of the part with the same diameter is greater than 50 mm, the straightness inspection should be carried out, and the working surface of the knife edge ruler should be in contact with the outer diameter busbar to observe the width of the building, and then use the standard optical gap to make judgments.

2. Measurement techniques for inner diameter

When measuring the inner diameter of a part, it is only necessary to measure three parts in the circumferential direction and make a record at the same time. When the length of the same diameter is greater than 40 mm, the cylindricity inspection should be carried out, and within the limits of the length direction of the same diameter, two positions with larger partitions are obtained for measurement. Calculate the cylindricity error.

3. Measurement techniques for outer rib

The middle diameter of outer rib is measured with a rib ring gauge or three needles, and the small diameter is measured with a rib ring gauge (general gauge).

4. Measurement skills of inner rib

The outer diameter of inner rib is detected by rib plug gauge (general gauge), and the middle diameter is detected by rib plug gauge.

5. Detection of surface roughness

The relative method of sample block is used for relative judgment.

6. Test of flatness

Using the punching method to test, three adjustable supports are placed on the flat plate, the measuring surface of the part is placed on the support point, and the support point is adjusted , let the three points have the same height, and the peak-to-valley value measured by the meter is the flatness error of the plane.

Professional quality inspection knowledge and relevant work experience are required, and various requirements for inspection work of advanced products must be met.

Applied testing and measurement equipment needs to be judged and qualified by a professional testing department and within the specified verification period.

Detect product production requirements, familiarize yourself with the relevant drawings and technical documents of the product, and inquire about the key points of the relationship between the dimensions of the processing of precision mechanical parts and the device.

The parts are judged strictly according to the requirements of drawings and related technical documents.

Service-based companies as Dongguan Yifeng Metal Co., Ltd. are increasingly becoming more popular internationally.
Energetic, optimistic entrepreneurs often tend to believe that sales growth will take care of everything, that Dongguan Yifeng Metal Co., Ltd. will be able to fund our own growth by generating profits.
The sheet metal manufacturing custom metal parts has significantly numerous benefits over other custom metal works systems, which makes it first choice for sheet metal manufacturing.
custom metal works custom metal parts is slower than sheet metal manufacturing but has a number of special applications, such as for custom metal works.
