High production machining device

A high production machining device comprising:

• a headstock;
• first and second spindles rotatably mounted on said headstock;
• a carriage;
• first drive means for sliding said carriage along a transverse axis of said machining device;
• first and second slides slidably mounted on said carriage for movement in a direction normal to said carriage for movement in a direction normal to said transverse axis, said first and second slides each adapted to carry a machine tool and attached to a common second drive means for moving said slides, said second drive means comprising a rotatable screw driven by a servo motor, said first and second slides being driven by said screw via first and second nuts, respectively;
• means for monitoring the positions of said first and second slides along said normal direction;
• and
• independent compensating means for adjusting the position of one of said slides relative the other slide in said normal direction, said independent compensating means being integrally connected to said second nut, said second nut being rotatably mounted on said rotatable screw and rotatably attached to said second slide, whereby said second nut can be rotated relative said rotatable screw by said independent compensating means, and whereby the position of said second slide in said normal direction is determined by the combined rotational input on said second nut by said screw and said independent compensating means such that the positions of said first and second slides in said normal direction can be effectively independently controlled.

A high production machining device comprising:

• a headstock rotatably supporting a first spindle and a second spindle, said first and second spindles mounted in axially parallel relationship;
• a carriage;
• first drive means for selectively sliding said carriage along a transverse axis of said machining device, said transverse axis being substantially parallel to said axially parallel spindles;
• first and second slides slidably mounted on said carriage for movement along an axis normal to said transverse axis, said first and second slides each adapted to carry a machine tool;
• second drive means for selectively moving said first and second slides along said normal axis;
• means for monitoring the positions of said first and second slides along said normal axis;
• independent compensating means for changing the position of one of said first and second slides along said normal axis relative the other slide, whereby the combination of said second drive means and said independent compensating means provides effective independent control of the respective positions of said first and second slides along said normal axis;
• and
• independent adjustment means for changing the axial position of one of said first and second spindles along said transverse axis relative the other spindle, whereby the relative positions of said first and second spindles in a direction parallel to said transverse axis can be effectively independently controlled.
