Lathe is a process that pemakanan workpiece sayatannya done by rotating the workpiece and then imposed on the chisel driven by translation parallel to the axis of rotation of the workpiece. Swivel movement of the workpiece is cut relative motion and move the translational motion of the chisel called bait.

By setting the ratio of the workpiece rotational speed and the speed of translational chisels to get some kind of screw with different sizes ranging. This can be done by way switch gear that connects the axis translation spindel the screw axis.

Exchanger gears provided specifically to meet the needs of manufacturing the screw. The number of teeth on each cog swapper size varies from the amount of up to 15 maximum number of 127 teeth. Exchanger gears with the number 127 has a specificity that is used for conversion from metric to a threaded screw inches.

Spindel axis of the workpiece will rotate through the carrier plate so that the gears rotate on its axis spindel. Through liaison gears, rotation will be communicated to the screw shaft gear. By clamp threaded, screw shaft rotation is converted into translational motion on the sled that carries a chisel. As a result the workpiece will be screw-shaped incision.

[edit] The parts of a lathe

Lathe machine consists of a table and his head still. At the head still have the wheels spin gear changers who will play spindel axis. Axis spindel will menmutar workpiece through gallant. Main sledge will move along the table with a sledge and sleigh on the latitude and chisel holder. The main source of all those moving from an electric motor to rotate through belt PULLEY.
