Thread: CNC Machine

That is what a five axis mill is for. However this sort of operation is for high priced low volume items. Production rate is low and material cost high due to waste. Another thing to look at is the grain flow of the metal in a billet as opposed to a casting or a forging. Imagine how many 5 axis machines would have been needed to make Chev. small blocks from billets at their production peak of 10,000 per day? I saw, in 1972, at Detroit Diesel Indianapolis, a machine called simply a "transfer machine" which took desanded and fettled cylinder block castings and performed progressively all machining, drilling, and tapping operations needed to produce a finished block. This took 43 separate operations, passing the casting around in the machine from operation to operation. Hence the name "transfer machine" as it transferred castings from station to station. It also maintained the castings at 200 degrees F., an engine's operating temperature. This machine was a major forward step in production machining as it had only one operator who basically was a monitor and tool changer. Nowadays the operator would be gone. The machine was the size of a medium house and contained 43 block castings at any time, one at each tool station.

That was as neat as!

Wonder how much one of them would cost for the shed?

frapt anyone?

I have seen CNC machining centres sell at auction from $10000 up. Tooling is a major cost. Need lots of end mills and slot drills mainly, plus other types of cutter, specialised insert tool holders for turning and threading operations plus mega lots of inserts. Programming skills needed as well as experience and good understanding of machining operations.

These machines are cool. Thats how Sainty's the drag racers also make their engines.

moose thats good

but you need to get a life go to work for a change turn that putey off and wipe your favourite site(im bored)

try going bush and go camping

I always wanted to turn a V8 into a coffee table
Somthing like this but a bit nicer. Seen one before where the cylinders were used for wine bottle holders. The last one i saw did not have the pistons as legs and looked better than this one

I like that coffee table, I wonder if the interior designer would?
