I want to understand if the tool change is working correctly. It seems to me that the chuck is pushing the feed plate too far.

I couldn't buy it, though, as the seller was asking too much for it, but I did get a photo of it.

The tool changer for the HSK63-f chuck is acting strangely. Sometimes it simply opens the collet and the ejector gently nudges it to release the chuck, but more often than not, it simply ejects it! What I did: carefully cleaned the inside with isopropyl alcohol, dried it with a paper towel, and lubricated it. But the ejection effect persisted. It was there from the very beginning, when I bought the machine; I just hadn't used the automatic tool changer until now. Now it's time to adjust it, and I noticed this behavior. Incidentally, one of the 10 HSK63-f chucks ejects only a little. I noticed that when clamping the tool, the ejector reaches the bottom of the chuck, resulting in a 0.9mm overhang from the spindle flange to the chuck. This ejector likely ejects it before the collet releases it. I'll attach a few photos with the changes. Please ignore the fact that the photos are sometimes taken with the tool positioned poorly for measuring. It's just hard to measure and take pictures with one hand. I don't know why, but I couldn't attach an additional video to this post.

To this day, fragments of a once great empire can be found at Sunday flea markets.

Although my HSD ES-325 spindle is factory-configured for liquid cooling, it was likely reconfigured for air cooling for font work. Luckily, out of curiosity, without a schematic, I started tinkering with the pneumatics. It turned out the pressure regulator was missing an adjustment screw, meaning I wasn't getting any air for cooling. Since the original screw wasn't in the machine, I found a suitable one and adjusted the pressure to 4 atmospheres, according to the manual! Hooray! Cooling started working! But you know what I was thinking? I still want to install water cooling! Can anyone recommend this system? Although I'm familiar with HVAC. I'm more concerned about whether the fluid might accidentally leak into the motor cavity. I think this is because there are NBR seals in there, and with age, they tend to dry out and shrink.

I ordered the clock board on AliExpress. The clock has such a gorgeous lamp; any lamp lover should have one!

Currently, I'm using a single-cutting-edge aluminum milling cutter with a DLC coating. I tried to keep the feed rate and the cutting depth low. If I've made any mistakes, please help me figure it out! I'd appreciate your expert comments.

According to the documentation I have for this spindle, it clearly states that it is liquid-cooled! But my machine doesn't have any additional devices for this. The seller claimed it was air-cooled. I used it for a while, and the spindle was cold, barely warm. But I'd like to be sure that nothing will happen to it if I continue to use it as it is currently connected to the machine. If you have had experience with this spindle and can advise me on how to properly operate it, I would be very grateful.

Hi! Since I have a CNC machine, it's impossible to work on it without a reference book or a calculator for calculating machining modes for different materials. I've had a good HP calculator lying around for ages, so it would be a shame to build a machinist's calculator using it! I'm not a programmer at all; neural networks and a strong desire to make my work easier and more accurate help me with coding. Perhaps someone has already tried this, and I'd be happy to share my experience and accept yours.

This is the future milliohmmeter.
