Key Differences
A spindle is a crucial component of various machines, designed to rotate and often hold another element. Whereas a mandrel is a type of spindle, but it is specifically designed to hold workpieces during processes like machining or metalworking.
Spindles are used in a wide range of applications, from woodworking to automotive manufacturing, to facilitate the rotation necessary for various machining tasks. On the other hand, mandrels are used more specifically to secure or support workpieces inside a machine, ensuring precise operations during manufacturing.
The design of a spindle can vary widely depending on its application, incorporating different features for speed, power, and torque. Whereas mandrels are generally simpler in design, focusing mainly on strength and accuracy to support the workpiece without adding additional functionality.
Spindles often connect directly to the power source of a machine, enabling them to drive the machine’s operations. On the other hand, mandrels may not directly interact with the power source but are crucial for the alignment and support of the workpiece.
In maintenance and operational contexts, spindles require regular checks and servicing to ensure optimal performance and safety. On the other hand, mandrels, while also needing maintenance, tend to have fewer mechanical components and therefore might require less frequent servicing.
