Automatic milling and drilling machine

A machining apparatus comprising:

• a lower part;
• an upper part having a lower side directed downward toward the lower part;
• a plurality of support posts fixed to the upper part and to the lower parts and holding the upper part fixedly at a spacing above the lower part;
• a tool holder mounted on the lower side of the upper housing part so as to be displaceable parallel to a horizontal tool axis;
• a chuck carried on the tool holder, rotatable about the tool axis, and adapted to hold a machining tool;
• a supply station on the lower part offset horizontally perpendicular to the tool axis from the tool holder and adapted to hold a workpiece;
• a workpiece chuck;
• and
• means including a cross slide mounted and movable on the upper part and carrying the workpiece chuck for displacement of the workpiece chuck in a horizontal direction perpendicular to the tool axis and in a vertical direction for displacing a workpiece between the supply station and a position aligned on the tool axis with the tool chuck.
