我们革新了球轴颈以及各种球面的加工方法(如附图),工件1用顶尖装在车床上,由拨盘带动旋转(转速n=15转/分)。在车床横拖板上装一小电动机,电动机上装一刀盘3,车刀2装于刀盘上由电动机带动旋转。刀具作圆周运动,工件作与刀具运动平面相垂直的旋转运动,故车出球面。 We have revolutionized the ball journals and various spherical processing methods (see attached drawings). The workpiece 1 is top-mounted on a lathe and rotated by a dial (speed n = 15 rpm). In the lathe transverse carriage mounted a small motor, the motor tops a knife plate 3, the knife mounted on the cutter 2 driven by the motor rotation. Tool for circular motion, the workpiece for the tool and the plane of motion perpendicular to the rotation, so the car out of the ball.
