Pressure Capacity: Pressure capacity refers to the maximum pressure the compressor can deliver, measured in PSI (pounds per square inch). A CNC machine typically requires a range of 90 to 120 PSI for effective operation. Higher pressure allows for more precise control and operation of pneumatic tools attached to the CNC machine. According to a study by McLean (2021), a compressor with adequate pressure capacity can improve the overall performance of CNC machining by reducing tool wear.
-
Airflow Rate: The airflow rate indicates how much air the compressor can deliver in a specific time, measured in CFM (cubic feet per minute). CNC machines frequently require a consistent airflow to operate smoothly. For example, if a CNC router needs 10 CFM for operation, an air compressor that can provide this rate will ensure the machine runs efficiently without interruptions. In a paper by Jenkins (2022), it was found that compressors with higher CFM ratings can boost productivity in manufacturing settings.
-
Tank Size: Tank size, measured in gallons, determines how much compressed air the system can store. A larger tank provides a buffer for air supply, ensuring that the CNC operates continuously without the compressor needing to cycle on and off frequently. For instance, a 30-gallon tank may be beneficial for larger CNC setups that require substantial air volume. The Ideal Compressor Brand Report (2023) suggests that optimal tank sizes vary based on application and machine demands.
-
Noise Level: Noise level, measured in decibels (dB), can affect workplace comfort. Most CNC shops benefit from quieter operations.
