One of my viewers sent me this job to do for him. This is a hardened precision ball screw for the product line he sells parts for. He asked me to film the job for all of my viewers, and hopes we can get some younger people interested in the trades.
First to do this job, I must anneal the machined area. The Monarch 18CU Lathe with Hardinge 2J collet chuck are the perfect setup for this work.

Well done Josh. recently I just had a job I needed to anneal a hard end like that and that's exactly what I decided to try, I figured I had nothing to lose. I heated it till it was just blue and let it cool. Worked the treat, the part that needed to stay hard stayed hard too. I have a hardened BT-30 tool shank I need to make a custom deal on the end and will try the same thing. It's knowing those little tricks and when you can use them that make things so fun and less frustrating.

@bostedtap8399 10 ай бұрын

Josh was tempering the part, not annealing , just bring down the previously hardened and tempered shaft to a lower hardness value. Guessing from 50 to 58 hardness Rockwell C (HRC), to 30 to 35 HRC.

@jeffreywhitmoyer860 Ай бұрын

@@bostedtap8399 I was going to make the same comment. The process is actually a temper. Heating to a blue like that probably puts it into the 700-900f range. In this case the light blue would suggest closer to 700, at 900 the color would be more violet. Not much higher than 900 you would start developing a light scale. 700-900 can be a dangerous range for some alloys as something known as temper embrittlement can occur. It's most common in 410 & 420 martensitic stainless steels.

@frankkent8046 10 ай бұрын

Great video! Question, I watch CEE along with watching you and Kurtis, when doing induction hardened chrome bar, uses a ceramic insert to cut away the hardened area before switching back to carbide inserts and doing whatever is needed. Could you have used a ceramic insert to do this job, that way you didn't have to anneal the rod, and potentially causing a failure due to lack of hardness on the ends? Thanks

@TopperMachineLLC 10 ай бұрын

Ceramic would not work in this instance. It would break in the interrupted cut of the thread. The screw was only hardened for the balls to roll in. Just a surface hardness. Annealing it will not affect the shaft long term. My customer said they wear out the screw, never break one. I have in the past turned induction hardened shafts with standard carbide. I just hand grind them to take the cut.

@mikeb1520 10 ай бұрын

I used to work for Schaeffler Group (FAG, INA bearings), when they needed to machine the ball screws they made, they were chucked in the lathe, coolant was put at the point they wanted it to remain hard, and then used a flame like you did to anneal it. I don’t recall what temperature they heated it to.

heating to blue is tempering, not annealing. annealing involves heating to critical temp, approx 1500 F and coooling slowly over several hours. Obviously, the tempering you have done is adequate softening for your turning but not completely softened. annealing would make it as soft as the steel can get.

@TopperMachineLLC 10 ай бұрын

It did soften it enough to not be a problem for machining. Guess my terminology is wrong.

That's a better job for grinding the splines. Those shafts are so hard, I don't think they would even anneal well. Years ago I swapped wheel hubs on a tandem axle truck.
