Abstract
A CNC lathe in which a first spindle stock is secured onto a base of a slant type inclined at a down gradient on this side, a second spindle stock opposed thereto is provided movably only in the direction of the spindle, and separate turret type tool rests are arranged in deep of the spindle stocks.
A CNC device having the aforesaid construction in which both spindle stocks are respectively provided with independent spindle motors, mechanically disconnectable spindle indexing and driving devices and encoders on the spindle and indexing and driving device, a CNC lathe for rotating the index motor on the basis of a phase difference detected by the encoder to effect adjustment of phases when the spindle indexing and driving device is connected to the spindle and when the workpiece is transferred between both the spindles.
A CNC device having the aforesaid construction provided with a synchronous control device for providing output pulses of the encoders mounted on both the spindles as a unit of fine time to correct a speed command according to the magnitude relation thereof.
According to this invention, there is provided a CNC lathe in which a rigidity of the first spindle stock is high, a bar feeder having a conventional construction can be used. Work efficiency at the spindles in composite workings including indexing and work efficiency for bar working including cutting off the end of the bar can be considerably enhanced.
