Which device is used to spray air and remove chips from a CNC machine?

The Air Nozzle is the correct device for spraying air to remove chips from a CNC machine. It is designed specifically to direct a stream of compressed air towards the work area, effectively blowing away the chips and debris generated during the machining process. This is essential for maintaining visibility of the cutting area and ensuring that the machine operates efficiently without interference from leftover material.

Using an Air Nozzle helps to prevent any build-up of chips, which can lead to problems such as tool wear or degradation of workpiece finish. It also aids in cooling the cutting area, thereby helping to prolong tool life and improve precision.

The other devices serve different purposes: a Chip Auger is designed to transport and remove chips from the machine's interior; a Vacuum Table is used for workholding and does not spray air; and a Coolant Pump circulates coolant to reduce heat during machining but does not specifically focus on chip removal. Thus, while all these devices have their roles, the Air Nozzle is the most effective for the specific task of spraying air to clear chips.
