Key Differences
Tailstock is a component found at the opposite end of the lathe bed from the headstock, primarily used to support the end of the workpiece through the center. It can hold tools for drilling, reaming, and threading operations. Whereas the headstock is located at the left end of the lathe bed, serving as the main driving force for the workpiece. It contains the spindle, motor, and gear mechanisms to rotate the workpiece at various speeds.
The tailstock can be adjusted and moved along the lathe bed to accommodate workpieces of different lengths, providing flexibility in the machining process. On the other hand, the headstock is usually fixed in position, establishing the primary rotational speed and power for the machining operation.
While the tailstock supports and aligns with the workpiece, ensuring precision in operations like drilling, the headstock's role is to hold the workpiece securely and impart the necessary rotation for machining.
In terms of functionality, the tailstock is essential for supporting the workpiece against lateral pressures from cutting operations, enhancing the stability and accuracy of the machining process. The headstock, however, is critical for the primary rotation and speed control of the workpiece, making it a key component in determining the lathe's operational capabilities.
The tailstock and headstock serve different purposes, they are complementary components of a lathe, each contributing significantly to the machine's overall functionality and precision in metalworking and woodworking operations.

Tailstock
A tailstock, also known as a foot stock, is a device often used as part of an engineering lathe, wood-turning lathe, or used in conjunction with a rotary table on a milling machine. It is usually used to apply support to the longitudinal rotary axis of a workpiece being machined.
Headstock
A headstock or peghead is part of a guitar or similar stringed instruments such as a lute, mandolin, banjo, ukulele and others of the lute lineage. The main function of a headstock is to house the pegs or mechanism that holds the strings at the "head" of the instrument.
Tailstock
A sliding carriage on a lathe that holds the center, the pointed part on which one end of the piece being worked spins.
Headstock
A nonmoving part of a machine or power tool that supports a revolving part, such as the spindle of a lathe.
Tailstock
The part of a lathe that supports the object being worked along its rotatory axis.
Headstock
The part of a stringed instrument adjoined to the end of the neck, where the strings are wound.Also called tuning head.
Tailstock
Support consisting of the movable part of a lathe that slides along the bed in alignment with the headstock and is locked into position to support the free end of the workpiece
Headstock
(mining) A headframe.
Headstock
A part of a machine (such as a lathe or drill) that supports a rotating part
Headstock
A beam that supports a bell.
Headstock
A clamp that restrains a cow by the neck.
Headstock
The part of a lute-type string instrument, such as a guitar, that holds the tuning pegs or tensioning screws of the strings.
Headstock
(rail) A transverse structural member at the extreme end of a rail vehicle's underframe, also used on some bogies.
Headstock
A part (usually separate from the bed or frame) for supporting some of the principal working parts of a machine
