フレームに上下一対の平行するガイドを架設す
ると共に、この上下ガイドに左右一対の振動体を
空気軸受を介して摺動自在に支持させ、前記左右
振動体の中間でかつ上下ガイドの中間にカム軸を
設け、このカム軸に前記左右振動体を夫々別個に
作動させる為の相反方向に等しく偏心した一対の
偏心カムを固定して該偏心カムを左右振動体の内
側面に当接させ、左右振動体の外側面にあつては
前記カム軸の中心を通りガイドと平行な線上に一
端を前記フレームに掛止させた押圧バネの他端を
弾接させ、該左右振動体にロツドに夫々工作物に
圧接させる砥石を付設した１個以上のシリンダに
よる砥石ヘツドを取付けた超仕上機に於いて、上
記ガイドを中空状に形成し、該ガイドの所定位置
にエアーノズルを設けて上記空気軸受を軸給気型
にしたことを特徴とする超仕上機。 A pair of upper and lower parallel guides is installed on the frame, and a pair of left and right vibrators are slidably supported on the upper and lower guides via air bearings, and a cam shaft is placed between the left and right vibrators and between the upper and lower guides. A pair of eccentric cams equally eccentric in opposite directions for operating the left and right vibrating bodies separately are fixed to this camshaft, and the eccentric cams are brought into contact with the inner surfaces of the left and right vibrating bodies, thereby suppressing the left and right vibrations. As for the outer surface of the body, the other end of a pressing spring whose one end is hooked to the frame is brought into elastic contact with a line passing through the center of the camshaft and parallel to the guide, and the workpiece is rod-likely attached to the left and right vibrating bodies. In a super-finishing machine equipped with a grinding wheel head consisting of one or more cylinders equipped with a grinding wheel that is pressed into contact with the grinding wheel, the guide is formed into a hollow shape, and an air nozzle is provided at a predetermined position of the guide so that the air bearing can be attached to the shaft. A super finishing machine characterized by being an air supply type.
