Machines | Heavy Metal Machining Part 1
videos | at work | information | view | construction
This video is the first of new series involving the machining of a new gearbox shaft. The material is 9 1/2" 4140 by 62" Long. To start with, I have to press the old shaft out of the gear. You'll see me set up on the press for some heating and press work first, then the removal of the second bearing. Later we'll move to the boring mill and lathe to start the machine work on the new material. Follow along as we turn a raw piece of shafting into a functional part that will be used in heavy industry.

I'm amazed that just that small engagement of the live center when you first started turning supported all that weight.

Old School work!
-
What about the case hardening on that gear?
Wont the torch aneal the metal? -
when we will sea the second part of the hydraulic class. thank you Erick 12/30/2016 6.34 pm

id it just me or is this relaxing.
-
How long would take for the steady to make a groove into a work piece that big and heavy?
-
I am interested to know what material the work piece is and what cutting inserts you are using since I notice you are not using any coolant and the RPM's are rather high for that diameter. I was surprised not to see any "sparking" coming off the cutter tip at that speed.

4 jaw real machinist chuck luv it. is that a ole swasey..case hardened grind bearing surface?
-
All the best for Christmas and the new year. Keep it up.....

Hi Adam. Please tell about speed feed of all operations in your videos for newbies like me.
-
whats the rpm?

Are gears always held on the shaft axially by a press fit and nothing else?
-
Hey bro awesome work
I'm loving the videos you do
I would love to get my hands on a nice chunk of that 4140 to make a bladesmithing anvil out of.
Even some of those roller bearing would make a really nice blade as they are usually made out of 52100
Anyway keep up the good work brother and have a good one. -
Will that gear need to be heat treated after hitting it with the torches?
-
skilled engineer great to watch
-
Dam you do some heavy work!

love it. I've built shafts that size. the one I built was a gear box shaft for a beet elevator. Basically big steel baskets capable of holding up to 100 gallons of beets and around 150-200 of them. they'd crush em for the sugar I think. all I know was it was a huge gear box. We'll over 10K pounds. I admire watching anyone machine. I like to see what we do different. not much tho. maybe a few things I would've done differently, but the end result is everyone's goal. good job. wish I made video of some of the shit I've built.
