What is special purpose machine

A special purpose machine (SPM) is a machine that is designed and built to perform a specific task or operation that cannot be performed by a standard or general-purpose machine.
These machines are highly customized and are designed to optimize efficiency and productivity for a particular process, such as manufacturing or assembly.
Special purpose machines are used in a wide range of industries, including automotive, aerospace, electronics, and manufacturing. They are typically designed to perform a repetitive task or series of tasks with high precision and accuracy.
Special purpose machines can be very complex or fairly simple, depending on the specific requirements of the task at hand.
