How much is the gas pressure in the processing center?
The pressure of compressed air required by machining centers is usually set between 0.5 and 0.7 megapascals (MPa), a range that can meet the operating requirements of most equipment. Specifically:
Core functional requirements
When the machine tool performs key operations such as tool changing and workpiece clamping, the air pressure needs to be stable at 0.6 to 0.7 MPa. If the air pressure is lower than 0.5 MPa, it may cause low pressure alarm or action failure, for example, the tool change mechanism cannot work normally.
Auxiliary function requirements
Auxiliary operations such as cleaning iron filings require lower air pressure, but still need to maintain more than 0.5 MPa to ensure cleaning effect.
pressure stability assurance
In order to avoid air pressure fluctuations affecting equipment operation, the following measures are recommended:
- Equipped with air storage tank: Buffers air pressure fluctuations to ensure continuous and stable gas supply.
- Set pressure margin: Considering the transmission loss of air from the air compressor to the equipment, it is recommended to set the output pressure of the air compressor to 1.1 to 1.2 times the required pressure of the equipment. For example, when the equipment requires 0.6 MPa, the air compressor output pressure can be set to 0.7 to 0.8 MPa.
actual application scenarios
The air pressure requirements of different equipment or functional modules may differ. For example:
- Some high-load clamping mechanisms may require air pressure close to 0.7 MPa.
- Precision machining scenarios may require a smaller range of air pressure fluctuations and need to be controlled by precision pressure regulating valves.
It is recommended to set the air pressure according to the equipment manual or manufacturer’s recommendations, and regularly check the stability of the air pressure to ensure efficient and safe operation of the machining center.
