    white spots on polished, anodized parts from porous metal?

    About 6 parts in my last batch came back with white spots/pock marks as seen in the image below (clearer in the second picture). After machining, I clean the parts thoroughly, then the finisher polishes them on a grinder and type II anodizes them. The finisher said it was the result of...

    anodizer delivering late, shifting timelines

    My anodizer consistently delivers late/shifts the timelines back. Says it'll be 3 days, then 3 more days, then 4 more days. I provide pretty small batch sizes, so I understand that I'm a lower priority, but the unpredictability is challenging. What do people do with their anodizers to lock down...

    using ChatGPT and other automation solutions, custom machining chatbot?

    Wondering if people have had good experience using ChatGPT in the machining world. Been using it like crazy for programming (Javascript web-apps) and it's at least doubled my speed. Been thinking about making a custom fine tuned model with embeddings based off of scraped data from this forum...

    fretting marks on toolholders, problem? how to fix?

    I'm getting fretting marks on my toolholders. Below are some examples, it is like that on most of the tools. Those lines can be rubbed off with my fingers, mostly those bigger dots. I also attached pictures of what the inside of the spindle taper. Only one side of the taper has marks. I have...

    does bright dipping affect part thickness?

    I am bright dipping my part along with anodization, my type II anodization adds a thickness of 0.0003″ and was wondering if bright dipping affects thickness. From what I know it's a very chemically harsh process that flattens out the surface, and strips a tiny bit away, is it enough to factor...

    CNC machine monitoring camera/microphone for broken tool detection

    I am looking for a cheap camera and/or microphone system that can automatically stop/reset my CNC mill if it detects a tool breakage. I want it to be quite cheap, and does not need to have any other features. In my mind, this seems like a no-brainer product that should be quite cheap (a few...

    BEST METHOD for cleaning coolant-machined Al parts for blasting and anodization??

    I am looking for the least amount of work to provide no staining (coolant or water) on my high quality/luxury “herb” grinder. We're going for the “Apple” feel so clean, even finish is very important (you can see it here: recreation.community). Process milling 6061-T6 aluminum with flood coolant...

    CNC mill preventative maintenance inspection/checkup

    I have had my Haas MiniMill 2 for about 2 years now, has been getting pretty light use as I've been using it for prototyping and only now entering production. I have looked at the preventative maintenance checklist and run through many of them. I am planning on going through it again shortly...

    spindle speed effect on spindle life

    I have a Haas Mini Mill 2 w/ a 6000 RPM spindle. From what I've read online, the RPM limit is made with a safety factor to allow you to run it all day. Like any machine though, maxing out the performance will lead to quicker wear. I'm wondering if anybody has any data (or anecdata) about running...

    lines from side-milling

    I am getting these faint marks from side-milling. Haas Mini Mill 2 @ 6000 rpm, rough = 0.01" and finish = 0.005" both at @ 0.002 IPT (recommended by Machining Advisor Pro). Interestingly, the marks are the exact same spacing as the diameter of the end mill, 3/16". The end mill is variable...
