What is a spindle?

A spindle is a rotating mechanical component that is primarily used in machine tools and machinery to hold and rotate workpieces or tools. Spindles are essential in CNC (Computer Numerical Control) machines, milling machines, lathes, and drilling machines, providing precise rotation for various machining operations.

Spindles perform several key functions:
・Rotation: They rotate tools or workpieces.
・Holding: They secure the tools or workpieces in position for precise machining.
・Power Transmission: They transmit power from the motor to the tool or workpiece.
Spindles come in different types, including main spindles (used in larger machines) and precision spindles (used for high-precision machining). Precision spindles are specifically designed for high-speed and high-accuracy applications.
Features:
・High Rotation Speed: Spindles can operate at very high speeds, making them ideal for precision machining.
・High Precision: Spindles provide precise rotation, essential for accurate machining.
・Durability: Spindles are designed for long-lasting durability, even under heavy use.
・Cooling: Some spindles come with integrated cooling systems to manage heat during extended use.

Application of spindle
