Efficiency in sawing, with quick set-up Ieatures.Speedy in production, it operates with precision and unusualeconomy. It is truly the outstanding beavy duty metal cuttingmachine in its field. The large 36" throat is obtained by one24Y2" drive pulley and two I8" diameter idler pulleys.

ilA Glt0D BAilr s^wThe NS-18 is a "prize winning" band saw, the easiest handling, most popularmachine on the market. Compact, rugged construction easy operation . . .
speed precision cutting and mechanical perlection combine to make thislow cost band saw a marvel in its iield. Its low cost is made possible by modernline production methods in our new, recently constructed plants, tooled for rnassproduction. The NS-18 is acclaimed by users as the finest metal cutting bandsaw on the market, because the most diflicult or intricate iob, Iarge or small, isaccurately cut with rare ease and precision. Many o{ America's largest plantshave battedes of NS-18 band saws in continuous operation. They report tremendoussavings in die costs, and hours cut lrom tormer die-cutting methods.

Under work pressure the saw blade deflectsso that it is supported on points only. A hard-ened steel guide such as a ball bearing guidecannot adjust itself and will tear and chew thesaw blade from the rear which will greatly
shorten the life ol the blade. The microscopic viewshows what happens to a saw blade when used withnon-self-seating guides
GNOB SETf.SEATING GUIDESSAVE SAW BI.AIDES
The problem to provide a large bearing sur-Iace under varying working pressure hasbeen solved with the Grob guides. After"seating" itself in the guide the back of thebale wears smooth as shown by microscopicview. Note how the surlace is actually im-
proved over new unused saw blade. Long life o{ theguides is assured by a felt oiler mounted directly abovethe upper guide.
Grob self-seating guides with the new Grob Lubricator are now recognizedas the most perfect and only satisfactory guide for contour metal sawing.The guides are made of tough hard aluminum bronze, Rockwell C-34.

Like any other cutting tool, eachsaw tooth must have sullicientback pressure to dig under thesurlace of the metal to be cutand remove a chip. Assuminga normal work pressure of 100lbs. the drawing to the left clear-ly shows what the saw blade isup against when used with aball bearing guide. It alsoproves the 7 advantages of theGrob guides listed above.
