Inspecting lathe turning tools with a digital microscope (Andonstar ADSM302)

let’s find out what’s in the Andonstar box that I got from Banggood for their 13th birthday. instructions of
digital microscope. User manual. Foam to make that island of waste in the ocean
even bigger. Here’s the interesting bit. A USB microscope.
I guess that is not really correct. it’s more like a stand-alone
microscope with an USB connector and what else, some cables and a remote control all that’s it. Nothing in the bottom of the box. Let me reframe this a little
bit. Now I’m not going to do a review video about this. Not now. That will come
later when I actually know a little bit about this machine. For now I just want to find the on switch and have a look at those lathe tool bits that I use in the
previous video. So I will be right back when I got this thing working well it seems to work. I’m using this old
laptop as a power supply. And I also stole some batteries for this remote
control. Luckily I don’t like watching TV. And I liberated a micro USB card. And I
already wrote down a few things to complain about in my review. but just
check out a beautiful picture that’s the important bit. I’ll bring the camera
closer. Let’s hope this video comes out looking okay. I set the camera to manual
focus. Otherwise it would pick up all the pixels, and you would get funky moire
effects. let’s start with the TCMT insert that I use for most of the
turning in the previous video. I must say this focus ring is a very smooth. And as you can see, it is pretty much damaged although it was cutting still fine. I
believe the technical name for this is cratering. That’s the background. Kind of
a funky, cool effect. let’s look at a new tip to compare
things. There seems to be a very slight edge. The same might be here…interesting. That will probably break off when you start using the insert. I must say the depth of field with his microscope is a lot better than with my regular camera
and a macro lens. That’s the closest I can get. Let’s take a picture. And as you
could see, it is shooting pictures in four by three format. Now let’s start
recording a video. And I will edit this in. Okay moving on to the second tool bit.
This is the CCMT insert that I used before I switched to the 4way tool post.
That looks almost undamaged, but there seems to be a little bit of cratering or
damage on the front of the cutting corner Let’s also look at a unused tip. That’s a
lot bluer. most of the blue color on this side has
worn off, or rubbed off. Not sure what kind of coating this is. Maybe it’s just
a lick of paint, I don’t know. let’s take out the insert and have a look at the
front corner. I’m using a little glue clamp to hold the insert vertical. And
there you can see the little crater. Don’t think I can get it any better.
Maybe if I move the lights a little. And I think this little bit of damage was
causing the insert to misbehave. And it might have already been there from the
start from new. Let’s also have a look at the new corner That’s the unused side. This looks a bit like a egg tooth, a little bit of a raised edge on the very tip of the corner.
Interesting I wonder if they are all like this. Alright moving on. This is the
piece of high speed steel that I used to try and get a better surface finish And it is looking pretty nasty on camera, or on microscope. And there seems to be a little bit of damage on the corner. And
there are also a few chunks missing on the cutting edge. It was a still cutting
fine but it might have performed performed better with some more honing
and stoning. This is the side looks okay. And last but not least the parting
tool. And as you can already see one of the corners is missing. Actually both of
the corners are a little bit damaged. I really should have resharpened this tool
bit before I use it But it was working before when I used it
in the 4way tool post. So I saw no need. Actually you can see this corner missing
with your naked eye. But I must have missed it. Okay one more, this is the blue
nano insert that I was using on the vintage lathe. And it pretty much still
looks intact. Although the very edge might be a little dull. But most of these
inserts have a rather large radius. And here’s the unused side. The radius might
look a little bit better on this side. But it was still cutting fine. Although most
of the color is gone, just like with the other insert. Pretty… Pretty ugly. Alright
that’s it for this short look at some tool bits. I had fun playing with this
Andonstar digital microscope. And I thought it was very useful, insightful
and even educational for me. And I do hope you liked it as well. You will
definitely see this again in one of my upcoming videos. And in about a month
time I should have made some sort of boring review video. but it certainly
won’t contain any unboxing footage, I’ve done that already.
now Banggood has asked me to inform you about their birthday party that should
be starting around this time and will be lasting for about a month or so. They
actually sent me a five page long boring and complicated document detailing all
kinds of bonuses, discounts and stages and some cash backs from new and
existing users. To be honest I did not really study it. But the most important
thing; You should buy your shit through my affiliate links. So I will make some
more of these videos. That’s it till next time. And I’m going to take a dump now.

  1. I was waiting for you to hook up the Allen Bradley to it, so we could hear that wonderful sound every time you went in and out front focus.
