What function does the auxiliary M code M88 serve?

• A. Turns coolant off
• B. Turns on high-pressure coolant
• C. Stops the spindle
• D. Changes cutting tools

Answer: (B)

The auxiliary M code M88 is used to turn on high-pressure coolant in CNC machining operations. High-pressure coolant improves the cooling of the tool and workpiece, enhances chip removal, and helps maintain a consistent cutting temperature, which can result in longer tool life and improved surface finishes on the machined part. This capability is especially important in machining operations using harder materials or when performing processes that generate significant heat. By utilizing M88, operators can ensure that the coolant system operates effectively during machining, leading to better overall efficiency and productivity.
