    MT3 vs R8 spindle taper

    Yes absolutely that’s a good way to go as well…should get you within 20-40um/.001-.002”. I think a slightly safer approach with this method is to bring the spindle down lower than the block then raise until the block barely slides under it. The tool setter I was referring to for more...

    MT3 vs R8 spindle taper

    You can also rig up a dial indicator and a 123 block to do the same. Feel free to PM if you need detailed help.

    MT3 vs R8 spindle taper

    Do you have a dial or digital tool setter? The process would be to set the probe against the reference ground surfaces of the setter and then move the quill to and down on to the “plunger” of the setter until it reads zero. The tool setter is obviously zeroed relative to the reference ground...

    MT3 vs R8 spindle taper

    Very nice. That would be the plan for the mill. I’ll use my Haimer in a probe TTS holder to set Z, then have all my tool heights programmed in linuxcnc. With my routers I do the same but because I’m using er20, I have to set each tool height against a tool setter before each op which is still...

    MT3 vs R8 spindle taper

    Based on the information I found on both the tormach and LMS sites, TTS require modified Collets for both spindle tapers: R8 flat like you said and a slightly shorter collet in the case of MT3 so the collets are not interfering with what the TTS needs to do. I also think the groove in the TTS...

    MT3 vs R8 spindle taper

    Oh I see what you are saying now. I found this picture from a 2015 article of someone who got a mill with the MT3(https://longezproject.blogspot.com/2015/03/cnc-mill-conversion-part-23.html?m=1). So if I understand the concept of TTS, it has to register against the quill otherwise it’s not...

    MT3 vs R8 spindle taper

    Thank you so much for taking the time to take pictures and provide additional information. Just to make sure I’m tracking: holder #3 from above is TTS in R8 while the er32 collet is in an MT3? I’m still not sure I understand the advantage of R8 over MT3 in terms od Z height. This is actually a...

    MT3 vs R8 spindle taper

    Yeah this probably true but given the price point I doubt the difference is anything but the end of the spindle shaft…I cant see an Asian budget manufacturer machining the same castings in two different ways for larger bearings or shaft…of-course I could be totally wrong. But I think I’m going...

    MT3 vs R8 spindle taper

    Wow I really appreciate the detailed explanation! I’m not sure I understand why the MT3 collets would extrude any further than the R8. Say for examples using something like this: https://littlemachineshop.com/products/product_view.php?ProductID=2023&category= With a “quick release” sort of...

    MT3 vs R8 spindle taper

    Very good to know and I appreciate the confirmation. I really do appreciate everyone’s advice and I totally understand that R8 is more popular in North America where as MT is more common in Europe. From a bit of research and from all the comments here I don’t think it will make that much...
