cnc acme thread with parting tool site www.practicalmachinist.com Acme threading will work best with a 2:1 length to diameter ratio. This means the most unsupported stick out you should have is 0.322”. You may have to center drill the part . Weather resistant electrical boxes are designed to protect electrical connections and devices from harsh outdoor elements such as rain, snow, and extreme temperatures. These boxes are made of durable materials like PVC or metal and have a tight seal to prevent water and debris from entering.

1) You can use a 5 pitch insert, but you may need to grind a little relief in it to get the depth. But it will have less tool pressure as the end is only .0689" wide or 20% or so less. . Ideally, the cut should be on one surface only, so it might be possible to cut an acme thread by using a 29.5 degree cutting tool to the desired depth, and then advancing the .

i have to cut a 4.750 stub acme internal thread. its 1 tpi and 6 leads so each thread is 6 inches in one revolution. im testing this out in a big haas tl lathe and it accepts fanuc style . 1) You can use a 5 pitch insert, but you may need to grind a little relief in it to get the depth. But it will have less tool pressure as the end is only .0689" wide or 20% or so less. 2) You can use a narrow grooving tool and pick out the thread bit by bit, then surface the thread using the radiused corners of the inserts. I was thinking about using a cutoff tool to cut the external block threads with, and then a grooving tool to do the internal threads, but it's hard to find a cutoff tool that narrow that would also work for me as a regular parting off tool. For cutting steep threads (acme or other) I've made a simple tool that holds carbide bits that can be adjusted to any helix angle. In fact I use this tool for most of my threading on the lathe. The one shown here is 5/8 dimeter using 1/8 inserts (ground from .
Ideally, the cut should be on one surface only, so it might be possible to cut an acme thread by using a 29.5 degree cutting tool to the desired depth, and then advancing the cut along the axis until the proper form is created. You would need a very skinny tool shank (almost certainly a custom tool), and be very limited in depth if you tried to threadmill this. I would buy some threaded rod from the source below and then file/grind some cutting edges into it to make a tap. To get a real handle on the specs of the Internal Thread: 1. Ensure there are no burs and hangups on the Internal Thread. 2. Plug the through hole up to the bottom of the Thread with Plasticine. 3. apply a good release agent to the Internal Thread and cast a mating Male Thread using Epoxy Resin, say Devcon. 4.
Acme threading will work best with a 2:1 length to diameter ratio. This means the most unsupported stick out you should have is 0.322”. You may have to center drill the part and use a live center, or chuck closer to the threading area to reduce part deflection.
