New Digital Micrometer for China

[jdrichard]

Just recieved my 0.001 accuracy digital micrometer from Aliexpress.com and it works like a charm.

I think their product quality improved over the years, I just ordered one timegrapher by the brand weishi from Taobao.com too..

Nice piece of kit Jd  I am in the process of acquiring some measuring gear of my own. That digital micrometer would complement my recent digital calipers purchase nicely. I am also looking to purchase a Fientaster (spelling) since the calipers are a bit crude for fine measurement. Mine are brand name and made to a DIN 862 specification as well as the company specs. The problem with made in china is when they deviate from the manufacturing standards imposed by the large corporations that use them to produce goods at price point. China is capable of producing some very nice stuff. Too bad the majority of its goods are on par with made in India...

While lacking the resolution of Jd's micrometer I am happy at .01mm with excellent repeatability.

And before I get flamed for measuring a pivot with calipers, rest assured this was a broken staff and I was curious as to the calipers ability and accuracy.

The build quality of the micrometer certainly looks to be excellent from the video, and the price is right...

There was one thing you forget to mention on your video JD.  

When you are machining a shaft to a specific diameter or machining a plate to a thickness, set the size on the micrometer first then zero the micrometer at that size.  When you do this and take measurements, you can read directly the plus or minus relative to the size you want.  It save you doing a wee calculation to get the correct amount of metal to remove.  Also when used as I gave described it makes a great comparator for checking the sizes of batches of things.

Great advice. I actually did not think of this, being an electronic guy by degree.

I also have a .01 micrometer and I found it really good for crystals and staff length but now accurate enough for pivots. Thoughts?

Sorry, had written a post but tried to delete it as I misread a previous post.

It's all good ☺
