A spindle motor is a small, high-precision, high-reliability electric motor that is used to rotate the shaft, or spindle, on which the platters are mounted in a hard disk drive (HDD).
How does a spindle work?
How Do Spindles Work? Machining spindles are often powered by electricity, but they can also be powered by compressed air. They’re available in a wide range of sizes to meet many different needs. A spindle is devised of a motor, a taper for holding tools, and a shaft that holds together all the separate components.
Which motor is used in spindle?
In the latter model, known as a variable-reluctance stepper motor, the spindle can achieve higher speeds than it could with a permanent magnet in the rotor. Stepper motors are the less popular and less powerful of the two motors most common to spindles.
What is spindle motor in CNC?
The spindle motor is what puts the “router” in “CNC router”. Usually mounted on a gantry, the spindle motor spins the cutting bit – the part that does all the work. … There are many different sizes and types of spindle motors to choose from, and they all meet different needs.
What is spindle movement?
The spindle movement of one division of thimble with spindle thread of 0.5 mm pitch is 0.01 mm. Explanation: … It is also used to measure the diameter of the pitch of a thread up to an accuracy of 0.01 mm.
Why is spindle used?
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.
What is the purpose of a spindle in an engine lathe?
A lathe spindle rotates the workpiece to be cut against a stationary rigid cutting tool, therefore removing material through the contact edge.
Which type of motor is not used in axis of spindle?
It is used in lifts, cranes, driving lathe machines, crushers but not used in axis or Spindle drive CNC machine tools.
Which motors are used in CNC?
The two motors most often used in CNC machine tools are stepper motors and servo motors. Both work to convert a non-linear input from the control into linear movement at the spindle shaft and table by turning a screw-like shaft to move the load.
Which motor is used in machine tools?
The great majority of machine tools are driven by alternating-current three-phase induction motors. These motors are simple, reliable and inexpensive. Direct-current motors are not so common and are used mainly to drive heavy, machine tools.

Which type of motor is used in spindle of CNC machine tool?
Stepper motors is used in axial or spindle drives of CNC machine tools.
What is the material of spindle?
Spindles are made of a wide range of standard materials, including high-carbon chromium bearing steel, Martensitic stainless steel, steel alloys and carbon steel for tools and machinery, aluminum chrome molybdenum steel and more.
What are the types of spindle drives?
Both types, the belt-driven and the integral motor spindles, have advantages and disadvantages according to their design.
How do you rotate spindles?
All spindles spin clockwise, some counter clockwise as well. You determine which way to cut out a part, not the machine, so whichever way around it you want to go. From contributor B: Spindles can spin both CW and CCW.
