本発明は、ベーンの製造方法に関し、特にべ−ン型圧縮
機に用いられる杆量なベーンの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field in Icheon) The present invention relates to a method for manufacturing a vane, and more particularly to a method for manufacturing a strong vane used in a vane type compressor.
（従来の技術）

急激に増大するため、回転数の上昇に作ってベーン先端
とシリンダ内周而との摩擦抵抗が増大してベーンの変形
、ベーンの摩粍（ＰＶ値）が大きくなってしまう。(Prior Art) Generally, in a vane type compressor, the tips of the vanes are pressed against the inner periphery of the cylinder by the force of the seedling 11 and the centrifugal force. Therefore, the vanes of conventional vane type compressors are made of a light alloy such as aluminum, such as a high-silicon aluminum alloy with excellent abrasiveness, in order to reduce the weight and improve wear resistance. However, recent vane type compressors tend to have a higher quadrupling speed, and as the rotation speed increases, the back pressure gradually decreases, but the centrifugal force increases rapidly, so the rotation speed increases. If the vane is made in the same manner, the frictional resistance between the tip of the vane and the inner periphery of the cylinder will increase, resulting in deformation of the vane and an increase in wear (PV value) of the vane.
そこで、高回転時における遠心力を小さくして前記摩擦
抵抗を小さくすることによりベーン型圧縮機の高回転化
を可能にするには、ベーン自体を軽量な形状にする必要
がある。Therefore, in order to enable the vane compressor to rotate at high speeds by reducing the centrifugal force at high speeds and reducing the frictional resistance, the vanes themselves need to be made lightweight.
ベーン自体を？１ｆｆｉな形状にする方法としては、例
