Definition. A spindle is a rotating shaft with a fixture for holding a tool (in the case of a milling, grinding, or drilling spindle) or a workpiece (in the case of a turning spindle). The spindle shaft serves as a support, a positioner, and a rotary drive for the tool or workpiece.
Is spindle and shaft same?
The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it (chuck, etc.).
What are spindles used for?
a rounded rod, usually of wood, tapering toward each end, used in hand-spinning to twist into thread the fibers drawn from the mass on the distaff, and on which the thread is wound as it is spun.
What is shaft axle and spindle?
Traditional nomenclature includes • Axle : A rotating member in rear axle assembly of the vehicles. • Shaft : A rotating member supporting attached elements. • Spindle : A short shaft or axle.
What is the function of the shaft?
Shaft form the important element of machines. They support rotating parts like gears and pulleys and are themselves supported by bearings resting in the rigid machine housing. The shafts perform the function of transmitting power from one rotating member to another supported by it or connected to it.
How many types of spindles are there?
Modern hand spindles fall into three basic categories: suspended spindles, supported spindles and grasped spindles.
What is spindle shape?
Definitions of spindle-shaped. adjective. tapering at each end. synonyms: cigar-shaped, fusiform pointed. having a point.
What is motor spindle?
A motor spindle has an integrated electric motor. By contrast, a separately driven spindle, such as, for example, a belt driven spindle, is driven by a belt pulley. Weiss Spindeltechnologie GmbH is a leading supplier around tool machine spindles.
What is difference between shaft and axle?
The shaft is a rotating element, circular in cross-section that supports transmission elements like gears, pulley, and transmits the power while the axel is a supporting rotating element like wheels, and is fitted to the housing by means of bearing.
What are the different types of axles?
Axles are essential components of any vehicle and come in three main types: front, rear, and stub.
What is the function of bearing?
Bearings perform the function of preventing damage from being done by this force to the part that supports the rotation, and also of maintaining the correct position of the rotating shaft. This function of bearings is what allows us to use our machines over and over again for an extended period of time.
What is spindle bearing?
Spindle bearings are single row angular contact ball bearings which support thrust loads in one direction. and are often used in machine tool spindles . At very high speeds, spindle bearings can simultaneously. absorb high radial forces and single direction axial forces . Spindle bearings have one open shoulder on.
What is CNC spindle?
What is a CNC Spindle? CNC spindle often refers to the shaft at the center of the rotating axis of the machine tools, sometimes spindle is used to refer to the entire rotary unit, including not only the shaft itself but its bearings and anything attached to it.
What is difference between shaft and axle?
The shaft is a rotating element, circular in cross-section that supports transmission elements like gears, pulley, and transmits the power while the axel is a supporting rotating element like wheels, and is fitted to the housing by means of bearing.
What is shaft design?
Shaft Design. • A shaft is the component of a mechanical device that transmits rotational motion and power. • It is integral to any mechanical system in which power is transmitted from a prime mover, such as an electric motor or an engine, to other rotating parts of the system.
What is Lineshaft drive?
What is the function of bearing?
Bearings perform the function of preventing damage from being done by this force to the part that supports the rotation, and also of maintaining the correct position of the rotating shaft. This function of bearings is what allows us to use our machines over and over again for an extended period of time.
Is spindle and shaft same?

What is shaft and example?
The definition of a shaft is a long, narrow handle or a long narrow part of something, a sudden bolt of light or a sudden flash of some feeling. The long narrow handle of a golf club is an example of a shaft. A long narrow mine shaft or a vertical elevator shaft are both examples of a shaft.
What is called bearing?
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.
What is main shaft?
main shaft in American English noun. Machinery. the principal shaft of a motor, transmission, etc. ( distinguished from jackshaft)
What is a shaft in a motor?
The shaft in a motor is a cylindrical component that extrudes out from the motor and its housing. The purpose of the shaft is to convert energy from the motor into the end use application. Precision pins and shafts operate as a function of speed vs torque.
