Role of Pneumatic Tubing in Machine Tools

Pneumatic systems in machine tools can be used for workpiece clamping and positioning, pneumatic actuators, door opening and closing, and air blow cleaning of workpieces and machining areas. The compressed air required for these functions is supplied through pneumatic tubing from the air source and control components to different points of use.

Common Pneumatic Piping Applications in Machine Tools

Pneumatic Piping Inside Machine Tools

Pneumatic cylinders, pneumatic clamps, positioning mechanisms, automatic doors, and other pneumatic components inside machine tools require compressed air supplied through pneumatic tubing. As installation space and tubing layout vary within the machine, tubing selection should consider working pressure, operating temperature, and bending requirements.

PU tubing provides high flexibility and good elasticity. Nylon 6 and Nylon 12 tubing can be selected according to their material properties and actual piping conditions.

These tubing types can be used with One-Touch Fittings based on the required connection method.

Pneumatic Piping Around Machine Tools

Blow guns around machine tools are commonly connected with PU coiled tubing for air blow cleaning of workpieces, workholding fixtures, or machining areas. The tubing can be pulled out as needed and retracts after use for easier storage.

When selecting PU coiled tubing, operating distance, working pressure, and fitting specifications should be considered.
