Hi, everyone. I am in the market for a low-speed, high-torque spindle to use with my inbound Onefinity Journeyman on steel. I have read a few extremely helpful threads on this forum about machining steel and high-torque spindles. One thread linked to an Austrian spindle manufacturer; I found a de…

Thanks for this. I took a look at the Hitachi WJ200; it looks very nice and costs a bit more than some of the other options–what attracted you to that unit specifically? Does it have to do with the upgrades you plan in the future?

Hi, @349iq2345 , I’ve inquired with Mechatron re: HFPM-8022-24-ER20. It is neither BT30 nor HSK, but should get me going with the ability to mill steel as well as other softer materials. I asked if it is available with HSK toolholder, but I expect the answer will be “no”. Interesting Mechatron of…

To be honest it came well recommended and supported (manual, videos, forums, etc), which for me with absolutely no CNC experience, was important. It also was feature rich, as many are, so I felt it would be a one-time purchase knowing it should have me covered. Some discussions I had had warned that…

Hi @U007D As a complete beginner to CNC and VFDs, I went with the Hitachi too for same reason @TMToronto mentioned - apparently the manual is much better than what comes with the cheaper Asian versions. I’ve been able to (slowly) read through parts that seem relevant and mostly be able to make sens…

I have a Mechatron spindle HFS-8022-24-ER20. It is water cooled for better low rpm performance. It is driven with a Hitachi WJ200 VFD. My spindle was bought with the power supply cable as an extra. The quality of the cable and connector Mechatron provided is excellent. Their cooling water conne…

I didn’t know Daniel can provide 4-pole spindles. I guess this is a bit of an experiment for us to figure out how effective this solution might be. So I wouldn’t say he’s officially offering them yet, but he may in the near future if these experiments work out. Did you get a datasheet or some …

Hey Brad, [image] U007D: Did you get a datasheet or some information about it? I would not buy a spindle, especially for such a demanding application, without having seen the speed/torque diagram, in order to see that the “constant torque” horizontal line really reaches down to 3,000 or less r…

[image] 349iq2345: I hope you report on it when you have it! I intend to, yes! [image] 349iq2345: What additional information this 202 page manual provides? I photographed the complete ToC of the manual. It does appear to cover every VFD setting and value, with explanation, among oth…

I wanted to update everyone on my steel-cutting adventure with the Onefinity Journeyman. Tl;dr: If you are patient (i.e. can tolerate slow feeds), you CAN cut steel! First, the bad news: I have used small 2mm and 6mm carbide endmills to keep surface speeds lower (and broke them). While I still h…
