Universal combined milling and boring machine

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The universal combined milling and boring machine shown in FIGS.
1 and 2 for multiaxial machining of workpieces includes machine column 1 standing upright on a pedestal or on the floor by means of adjustable mounting elements 2.
Cross slide 3 is guided horizontally in the X axis on the top side of column 1 by means of parallel linear guides 4 running normal to the plane of the drawing in FIG.
1.
Cross slide 3 is driven by a motor (not shown) on ball caster spindle 5.
Cross slide 3 has a continuous center part 3a and two side walls 3b which are spaced a distance apart and on which saddle carriage 6 travels in the Z axis over linear guides 7 running normal to the plane of the drawing in FIG.
2.
Saddle carriage 6 is driven by motor 8 with toothed belt 9 and spindle 10.
Saddle carriage 6 has front part 6a between two side walls 3b, with vertical spindle head 11 guided on the end face of the front part so it can travel vertically in the Y axis over guide elements 13.
Spindle head 11 includes work spindle 12.
The traversing motion of spindle head 11 is accomplished by motor 14 with toothed belt 15 and drive spindle 16.
The vertical position of work spindle 12 can be adjusted manually by hand crank 17 shown in FIG.
2 on the front face of spindle head 11.
Supporting console 18, with work table 19 thereon, is arranged on the front face of machine column 1 so that it can be pivoted about horizontal axis 21 by means of a servo drive 20 shown in FIG.
1 between a horizontal machining position (indicated with solid lines in FIG.
2) and a vertical machining position (shown with dotted lines).
Supporting console 18 has circular foot 18a, as seen in the front view in FIG.
2, and supporting projection 18b that extends parallel to the horizontal axis and supports work table 19.
The work table is formed as a rotary table on supporting surface 22.
This work table can be pivoted about axis 25 normal to swivel axis 21 by servo drive 24 operated by hand wheel 23
