Function

A lathe machine is a tool that spins a block of a material and when abrasive or cutting tools are applied to the material, it can be shaped to produce an object with rotational symmetry on an axis of rotation. Lathe chucks are one of the many essential parts that are necessary for the proper functioning of lathes. Lathe chucks are adjustable and used to hold objects securely in the lathe machine.

Types

There are several different types of lathe chucks, all employed for specific uses. Some popular types of lathe chucks are scroll type lathe chucks, independent jaw chucks, combination jaw lathe chucks, draw tube actuated lathe chucks and front-mounted self-contained lathe chucks. Each type of lathe chuck offers its advantages and disadvantages.

Parts

A lathe chuck is a relatively simple device. There are only a few major parts that go into the construction of a lathe chuck. Each lathe chuck consists of a spindle and jaws. The jaws are used to grip the item to be worked on with the lathe. A lot of lathe chuck models are available with either two, three, four or six jaws depending on the manufacturer.

Features

Each type of lathe chuck has several features. Scroll type chucks are adjusted with a T-handle wrench that turns the scroll causing the jaws to adjust. Independent jaw chucks feature the ability of each jaw being able to be adjusted individually. These chucks are ideal for irregular-shaped objects. Adjusting combination jaw lathe chucks can be done by turning the spindle with a T-handle wrench or individually adjusting each jaw.

Cost

Different types of lathe chucks command different prices. Lathe chucks are generally not cheap. Lathe chucks can be found for just less than £65 to several hundred dollars. Some high-grade lathe chucks can cost well more than £650. Lathe chuck systems can be bought assembled or disassembled. The cost of a lathe chuck is heavily dependent on type and size.
