1,098,056. Milling. H. DECKEL, and F. W. DECKEL. Aug. 27, 1965 [Aug. 28, 1964], No. 37059/65. Headings B3B and B3K. A machine tool comprises a displaceable tool spindle 26 and a work-table 38 rotatable about a first axis A-A inclined to the table surface and about a second axis B-B inclined to the first axis, the point of intersection R being above the table at a distance of about one-half of the total spindle displacement. Hand wheels 14, 28, 30 control cross-movement of a slide 12, adjustment of a column 20 and vertical adjustment of a spindle head 24. The circular, square or rectangular table 34 is indexed by a device 42 about the axis B-B and clamped by a lever 40 to a plate 32 rotatable about the axis A-A. When four sides of a workpiece have been machined by indexing about the axis B-B, rotation about the axis A-A brings the fifth workpiece side into the same position as the others occupied. In a modification, a table 34, Fig. 2, is rotatable about an axis C on a plate 32 rotatable about the first axis A on a carrier 12 rotatable about a second axis B. |
