Lathe jaws hold the material being turned and can be clamped individually or automatically. Fragile workpieces cannot be clamped due to extreme pressure. Proper clamping is necessary for accurate rotation. Lathes are sized based on chuck diameter and some jaws are designed for hollow pieces. Clothing should not contact the lathe jaws while in motion to prevent injury.
Lathe jaws are the components found on a lathe that hold the material being turned or machined. Commonly found in metal lathe construction, the jaws of the lathe can be individually clamped or automatically clamped to center the workpiece by turning a single set screw. More typical in a three- or four-jaw configuration, lathe jaws are made of hardened steel and have a smooth gripping surface that holds the workpiece in place by pressure instead of physically biting into the material, much like the chuck on a lathe motor. an electric drill. Due to the extreme pressure exerted on the workpiece by the lathe jaws, fragile workpieces cannot be clamped in the jaws and must use an alternative actuation method.
In order for an object to be turned into a perfectly centered workpiece, it must be properly clamped in the jaws of the lathe. If you don’t make sure the object is centered, it will wobble during rotation, preventing it from being rotated accurately to center. However, an out-of-round or off-center object can be turned. This will require more material to be pulled off one side of the piece than the other and will leave an out-of-round stock piece on the end that has been jammed in the jaws that need to be removed. This is very costly, as the amount of material that is removed is too much and turned into waste.
Lathes are typically sized based on the diameter of their chuck or the size material that can be safely turned in their jaws. Most lathes have replaceable chucks that allow you to change the size and style of the chuck to fit a particular project. Many times, you need to change chucks to provide three or four lathe jaws. Some jaws are designed to be used within the diameter of an open piece of metal. In this application, the jaws are inserted into the workpiece and opened to clamp against the inside walls of the hollow pipe or workpiece.
The spindle of a lathe is driven by a very powerful motor. It is very important that no clothing contact the lathe jaws while they are in motion, as serious injury or death could result. One of the most common injuries to lathe operators comes from failure to remove the adjustment key from the lathe jaws. This tool can fly out of the spindle at very high speed, causing serious injury.
