Used Metal Lathes


Metal lathe fixing a Warco VMC turret mill.

By · Tuesday, January 12th, 2010


China meets Taiwan as the reworked and rebuilt new Chinese 13×30 metal lathe now fixes the manufacturing faults on a Taiwanese made turret milling machine. Although the mill was accurately set up, the methods used at the assembly factory to get this accuracy are very crude. Using hand held grinders and corse files to remove metal from bearing surfaces is crap by anyones standards, and what methods a worker uses on one machine, they will use on the next. So there will be many more like this …

A great refacing job.. amazing how poorly they worked it from the Factory.. the “hand grinder” is a common tool there I’m sure.. It’s about how fast they pump them out the door.. not how good the quality of the machine is.. -Rob

Hello

The feed is intentionaly very fine on this job to give an extremely smooth finish, you can see the diference between it and the origional rapid feedrate and crude hand finishing done at the factory. When the parts are mated together with a film of oil between they rotate smoothly and quietly, as if on ball bearings, instead of like rubbing two cheese graters together as supplied.

Id say the feed is a tad low for cast iron! ;) good job tho!

I keep wondering is the chinese worker has any pride in his work at all? Must be awful working a blue collar job there!?

Very well done. What brand, shape, size, and grade of carbide insert are you using?

Nice job
