All others will be transported to the printing device. Description of the Almen Strip Sqe Measurement Process The laser measurement of the strips is completely independent from sae j442 production of the strips.

According the final results of the reading, the conveyer belt will transport the strips to a number of collection buckets which will receive the particular strips. Therefore the flatness of sae j442 strip is of crucial importance. This is sae j442 important since the high measurement accuracy depends on an absolutely uniform measurement condition.

So it would be possible to limit this high degree of quality control to sae j442 premium quality Almen strip only. Those strips, which do not fulfil any of PA’s tolerances, are rejected from the very sae j442. The ink used for such a purpose is supposed to fulfil special requirements. Since the strip will be peened on the side which has no print, the reading remains on the strip even after the treatment.

Flatness of both sides printed on laser measured Almen strip For any sae j442 peening facility, the Almen intensity is, besides the coverage, the most important sae j442 parameter.

After the peening of a strip, an Almen gage, which often has sae j442 resolution of 1 micron, is used to measure the arc height of the strip. One of the key parameters for Almen strips sae j442 their flatness. However, Peening Accessories made the decision to use this technology for all its strips. This was, like any manual process, not completely free of mistakes. The laser measurement of the strips is completely independent from the production of the strips.

Reaching a certain point of the conveying system, tiny air cylinders will press the strip with a defined pressure onto the measurement block. Basically all large aircraft or aero engine manufacturers have their own.

But besides the normally very strict aviation industry specifications, manufacturers in the automotive industry, spring industry, etc.

Peening Accessories j4442 convinced that it has again taken a step in the right direction to increase the quality control of the peening sae j442. However, only for Peening Accessories best quality, the AERO strip, the flatness was measured manually for each single strip.

A laser sensor will sae j442 measure out the upper surface. There are also plenty of so called manufacturer specifications. A distribution and selection system for the strips has been integrated in the measuring process.

Quality Control sae j442 Almen Strips From each lot of newly manufactured strips, samples are taken and sae j442 in terms of hardness, finish and mechanical dimensions. There sae j442 a large number of specifications which define the material, hardness, dimensions, finish and manufacturing means for Almen strips. The belt has just the width of a strip. Almen strips are used to determine or to re-confirm the peening intensity.

Furthermore it has to be resistant sqe oil and to wear of friction. After sa tests, the right ink was found.

Standard: SAE J442

Since both sides of the strip will be measured, a small robot grip will take the strip and turn it around for the second reading.

From each lot sae j442 newly manufactured strips, samples are taken and checked in terms of hardness, finish and mechanical dimensions. For any shot peening facility, the Almen intensity is, besides the coverage, sae j442 most important peening parameter. Both flatness values will be printed onto the strip side, which has the reading with the larger value.

Therefore it is not surprising that the demand for high quality Almen strips is ever increasing. sae j442

The already finished and corrosion protected strips will be charged into a vibrating bowl, which feeds the strips, one by one, to a sae j442 conveyer belt.

So depending on the reading, the robot will rotate the strip again to prepare it for the printing. There is a clear tendency that the requirements in the specifications get more and more stringent. The 3 most widely used specifications for Almen strips have the following flatness tolerances:.

The 3 most widely used specifications for Almen strips have the following saf tolerances: Naturally, measuring with such an accuracy, the sae j442 of the strips will influence the reading to a j442 extent. Conclusion Using such laser measured and marked Almen strips, the m442 is able to visually identify immediately that each strip has been manufactured according to sae j442 required flatness tolerance.

This is for good reason. Flatness of both sae j442 printed on laser measured Almen strip. Finally the laser measured strips are ready for packing. Therefore, starting fromeach and every strip, regardless of its type, will be laser measured. Using such laser sae j442 and marked Almen strips, the customer is able to visually identify immediately that each strip has been manufactured according to the required flatness tolerance.
