Dainichi are well known for their range of Universal Machine Tools of which the basis is a substantially built geared-head lathe with (varying model by model) a horizontal miller, a very-heavily built Morse taper drill press (that can be pressed into use for light milling) and a shaper.  Popular on Japanese ships, they were, according to an experienced marine engineer, frequently fitted to those built by both Kawasaki and Mitsubishi Heavy Industries; the last vessel that he saw with a Dainichi fitted, was being launched around 1985 from the Hudong Shipyard in Shanghi.
If anyone can furnish further details or pictures, catalogs or handbooks about these interesting machine tools, the writer will be pleased to hear from you.
Dainichi built their first Universal Lathe, the DL6, in 1937 - with a much modified and heavier version being introduced in 1952. By  the mid 1970s the Company was offering a range of 13 versions of their universal machine tool, 26 different conventional lathes and 9 shapers. Today, their 41,000 square metre plant in Gifu, Japan, is still busy, turning out very heavy conventional and CNC lathes and other machine tools.
