Holland Vertical Miller
USA


Seldom found, the Holland vertical milling machine was manufactured in Fitchburg, MA, probably during the 1930s and into the 1940s. A useful-looking machine, the entire, rather massive head assembly complete with motor and drive system, was arranged to swivel 90 each side of vertical - the clamping arrangement being four closely-spaced bolts at the front. The usual Brown & Sharpe No.7 taper was used in the 2.5-inch diameter quill, this being extended under the control of a lever through a range of around 2.75" - there was no fine-feed handwheel fitted. The maximum clearance between the spindle nose and the top of the table was 11.25" and the minimum 2.25". Unusually, the head was elevated by a vertically-disposed screw thread, the controlling handwheel being set vertically at the top of the column. 
Speeds were all V-belt driven and arranged in two sets, the upper giving four speeds direct from the 1/3 h.p. motor and the lower the option of three more. The result was a range of twelve very useful speeds arranged in geometrical progression: 200, 300, 400, 600, 900, 1200, 1500, 1650, 2450, 3300 and 4375 r.p.m.
Heavily constructed,  the 8" x 26" table carried three T-slots and had 14.5" of longitudinal travel and 8" in traverse. Rather fine, bevelled-faced micrometer dials were fitted and a single balanced handwheel at the left-hand end.
Did the Holland company make other machine tools? If a reader can help on this point the writer would be delighted to hear from you..
