The item pictured right here (which you guys nailed nearly instantly) is called a boring bar [insert drinking pun here], which is used on a metallic lathe to chop the within of a component. I exploit this software much less ceaselessly than most of my different lathe tooling, however it’s nonetheless indispensable. Extra about what to do with this sucker after the leap.
The boring bar is used on a metallic lathe, a machine software that spins a component whereas transferring a slicing software to take away materials from the half, to enlarge the within diameter of a piece piece and, probably, to chop that dimension to a good tolerance. Sometimes, drill bits are used to machine smaller diameter holes within the heart of labor items, however when you’ve received a 2-inch gap to make in a bit of metal, you’re reaching for the boring bar.
The massive block on the correct attaches it to the software holder. The bar on the left is the place the motion occurs, holding the slicing software out away from the software submit, which permits it to be inserted into the middle of a rotating work piece (assuming you’ve already received a gap in it sufficiently big for the boring bar to slot in and, properly, start boring).
Making considered one of these is an inexpensive challenge for the house machinist, and a helpful one. Simply don’t speak an excessive amount of about it or individuals could discover you … uninteresting.
Congrats to PopSci consumer “1177”, who guessed this software straight away!
