CNC Lathe Motors Mounted

July 24th, 2014

Send Out the Dancing Girls

Should have appended this to my last post.

Yesterday I stuck the motors on my CNC lathe. The plans called for 10-32 screws, which seems like a bad idea on a metric lathe. I followed the plans, and I ended up with threaded holes bigger than the holes on the motors. In order to pass a 10-32 screw without a lot of slop, you need a hole drilled by a #10 bit, pretty much. That’s the size I chose. I put the motors on the mill with a stop in the vise, and I lined the holes up with the drill chuck as well as possible, and I opened the holes up using my one of my lovely new Harbor Freight HSS drill bits.

The motors screwed right onto the mounts. No problems. Like they grew there.

The lathe is virtually done. I have to put a lead screw on it, which is a nothing job, and I also have to install a sensor and two couplers. The knurled knobs need to be opened up a little, and I need to put set screws in them, but that’s very easy.

I did a fine job modifying the lathe, and I even improved a couple of things. Now I’m just waiting for a few parts, including the power supply. I think I’ll start my Meshcam trial on Monday.

If I were starting fresh, I’d use metric stuff for as many items as possible, but it won’t matter.

I am wondering what else can be done with a lathe. What if I had a milling attachment? That could be used for things like broaching. What if I CNC’d the spindle motor? It seems to me that a lathe could do a lot of milly things if it were set up right. I just have to go slow and see what works.

    Time for you to get a subscription to Digital Machinist magazine,

    Something I should have thought of already.
