Processing center gas consumption how many cubic meters

2026-04-15Views:

The gas consumption of the processing center varies depending on the equipment model, functional configuration and usage scenario, it is about 0.4 cubic meters/minute during standby, and the gas supply of more than 0.9 cubic meters/minute shall be guaranteed during operation. The specific analysis is as follows:

core Scenario and Demand of Gas Consumption in Machining Center

the gas demand for machining centers is divided into two main categories:

  1. gas for core functions of machine tools: Including CNC tool change, automatic machine tool action, etc., need to maintain a stable pressure of 0.7MPa. Insufficient air pressure (e. g. less than 0.5MPa) may trigger a low pressure alarm or equipment abnormality.
  2. Auxiliary function gas: For example, blowing iron chips and cleaning workpiece, the air pressure above 0.5MPa is required to ensure the effect. If the air pressure is too low, insufficient cleaning force may affect the machining accuracy.

Typical Gas Consumption Data Reference

  • standby state: It takes about 400L/min (I .e. 0.4 cubic meters/minute), and the equipment only maintains the basic function operation at this time.
  • Running status: It is necessary to ensure a gas supply of at least 900L/min (I. e. 0.9 cubic meters/min) to support high-load operations such as tool change and blowing. If the equipment is equipped with special functions such as spindle siphon, the air consumption may increase by more than 100L/min.

Special configuration and optimization recommendations

  • gas tank configuration: It is recommended to install an air storage tank to stabilize the air pressure and avoid equipment failure due to air pressure fluctuations. The capacity of the gas tank can be calculated according to the peak gas consumption and continuous demand of the equipment, for example:
    V=P1 −P2 Q×t
    (Where V is the volume of the gas storage tank, Q is the compressor flow rate, T is the gas consumption time, P1 & minus;P2 is the pressure difference)
  • selection of air compressor: Take a single processing center as an example. If 0.9 cubic meters/minute of air supply is required for operation, considering the fluctuation and loss of air consumption, it is recommended to select an air compressor with a displacement of more than 1.2 cubic meters/minute and reserve a redundancy coefficient of 20%.
  • Multi-device collaboration: If multiple machining centers are deployed in the workshop, the gas supply scheme shall be adjusted according to the simultaneous utilization rate. For example, if 40 sets of equipment are not running at full load at the same time, a 3 cubic meter/minute air compressor (with 1.5 cubic meter air storage tank) can meet the demand.

Energy saving and efficiency optimization

  • air pressure management: The air pressure is precisely controlled within the range of 0.5-0.7MPa through the pressure regulating valve to avoid energy waste caused by excessive pressure.
  • Staggering time: Time mismatch for high air consumption operations (e. g. centralized blowing) to reduce instantaneous peak demand and reduce tank capacity and pipeline diameter pressure.
  • Equipment Upgrade: The selection of new energy-saving machining centers (such as equipment using Blue Technology) can reduce air consumption by about 70% and improve performance at the same time.
