HOW TO CHOOSE MANUAL LATHE FOR YOUR WORKING

How to choose Manual Lathe to have best your working!!!!!!

A lathe is basically a machine that cuts by placing a cutting tool (bite) on a rotating cylindrical workpiece. It will be easier to understand if you imagine the process of making a kokeshi doll. Thread cutting is also done on a lathe. When selecting a lathe, there are two specifications that you must check: "center distance" and "bed swing."
Center Distance: This indicates
The maximum length of a workpiece that can be attached to a lathe and machined..

For example, when machining a round bar, a machine with a 350mm center distance can physically handle workpieces up to 350mm long.
In actual lathe work, a three-jaw or four-jaw chuck is used, and a live center or drill chuck is also attached to the tailstock, so the length of the workpiece that can be handled is considerably shorter than 350mm. Also, while it is possible to machine a 350mm round bar on a lathe with a 350mm center distance, there are doubts about whether this can be done comfortably. Ultimately, it is safer to think of a workpiece that is about 60% the center distance as the range in which it can be machined comfortably. With a 350mm center distance, the maximum length would be around 200-250mm.
Bed swing: This indicates
The maximum diameter of a workpiece that can be attached to a lathe and rotated
. As with the distance between centers, machining a workpiece with a diameter the same size as the bed swing often results in difficulty. However, thin objects such as wheels can be machined relatively well even if the workpiece diameter is large. Another thing to note is that many operations use three-jaw or four-jaw chucks, so even if the bed swing is 150 mm, if the diameter of the three-jaw or four-jaw chuck used is 80 mm, then only workpieces up to 80 mm in diameter can be machined using that chuck.
In any case, both "distance between centers" and "bed swing" simply represent the maximum length and maximum diameter, and it is extremely difficult to machine workpieces with both the maximum length and maximum diameter . There are many other values ​​listed in the specifications table, but first, you should focus on "distance between centers" and "bed swing" . Also, when selecting a model, please keep in mind that it is safer to choose a model that is somewhat larger.
