Waltham, MA, May 12, 1998. Bird Precision orifices meet the stringent control requirements for orifice design found in medical ventilators and breathing apparatus.
Medically controlled oxygen flow requires orifices made of non-combustible materials which are burr free and accurate as well as extremely clean. Common machining methods such as drilling, EDM or laser do not produce the sharp edged, burr free, lapped surfaces needed for today’s medical gas delivery systems.
Bird’s ruby orifices are wire lapped in a high production method ensuring accurate, burr free surfaces with 2 micro inch finishes, both on the I.D. and faces. Accurate holes also insure predictable delivery quantities and guarantee that each orifice will be repeatable even in high volume applications.
Bird Precision of Waltham, MA has been creating precise jewel bearings and orifices since 1913. Their orifices range in size from .0008” to .0350”, and can be produced in high volume with extreme accuracy. These orifices have been used in a variety of applications and industries in need of flow restriction, including medical equipment and instruments, OEM applications, aerospace equipment, transportation engines and parts, and many others.
