Which jog key activates the Through Spindle Coolant system in MDI mode?

• A. AUX CLNT
• B. FEED HOLD
• C. RAPID
• D. POWER

Answer: (A)

The jog key that activates the Through Spindle Coolant system in MDI mode is the AUX CLNT. This key is specifically designed to control additional auxiliary functions within the CNC machine, including coolant systems. When using the AUX CLNT command, operators can initiate and manage the flow of coolant through the spindle during machining. This is crucial for maintaining tool life, enhancing machining efficiency, and achieving better surface finish on the workpiece. Other jog keys serve different purposes: the FEED HOLD key is used to pause the machine during operation for safety or to make adjustments, the RAPID key allows the machine to move at its maximum speed but does not control auxiliary functions, and the POWER key is generally associated with turning the machine on or off rather than controlling specific features like coolant systems. Each of these keys has its own distinct function that does not pertain to activating the Through Spindle Coolant system.
