The machine is of modern design and incorporates most improvements which
HOLROYD developed, such as: "possibility to use conventional high-speed
steel cutting tooling, as well as Tungsten-Carbide indexing-tip inserted
blade cutters in the climb-milling mode."
"Automatic backlash take-up" is provided. The cutter-head is of extra rugged
construction. The cutter spindle is rigidly supported in opposed taper
roller bearings and thru the use of a flywheel, a damping effect and smooth
cut are imparted to the mounted cutters. Maximum effect has been exercised
in making changes in settings and adjustments easy and effortless, without
disturbing alignments and/or accuracy. Most of the function controls are
duplicated on the machine, in front, and in the rear, for maximum operator
convenience.
