plain turning
There is no difference between a turning machine and a lathe. They are two names for the same kind of machine
Chuck, Collet, Faceplate, between centers
The two factors that determine the size of a lathe are the "swing" and "distance between centers". The swing of a lathe is the length measured from the center of the hollow spindle or chuck to the nearest part of the bed multiplied by two. Distance between centers is the distance measured between the chuck and tail stock.
All lathes could be considered "centre lathes." You turn "between centers." There's also a tool called a "machining center," but those are for computerized milling, normally of metal.
A blanchard lathe is a lathe for turning irregular forms after a given pattern, such as lasts, gunstocks, etc.
There are various ways for a lathe to hold its workpiece.The workpiece could be held between centers from the spindle and tail stockIt could be gripped in a chuckA faceplate could be used and the workpiece is screwed, bolted or clamped to it.
One can purchase a wood turning lathe at several locations. One can buy a lathe at a large store, like Sears, or a woodwork store or at an auction site like eBay.
The lathe (apparatus for turning wood or metal) is called "un tour" (masc.) in French.
cnc lathe
During the facing process of a workpiece over its entire face, the center is not required and is not set into the workpiece, therefore no forces are present on the center.
The lathe is Specified on the basis on the following factors: 1.Lathe swing or simply swing i.e maximum diameter of the workpiece that can be machined. 2.Maximum distance between the HEadstock and tailstock. 3.Length of the bed. then there are many kinds of lathe categorized by their specific functions or mechanisms but these are the general specifications for every lathe.
