Class refers to a specific combination of pressing capacity, diameter of work, and vertical capacity listed in table 1. 3. SALIENT CHARACTERISTICS 3.1 Frame. The fiame shall be of the “C” (gap) type and shall support the r
10、am and ram operating mechanism. The fiame table shall have a slot aligned with the axis of the ram which will allow passage of the arbor. The Came shall be designed for both bench and pedestal mounting. When specified (see 7.3), a pedestal and mounting hardware shall be supplied. 3.2 Bolster date. A
11、 circular bolster plate shall be provided with not less than four equaily spaced slots of varying widihs for the passage of an arbor. The bolster plate shall be removable and shall allow the desired plate slot to be positioned below the ram. 3.3 Ram and ram oDerating mechanism. The ram shall be of t
12、he rack-and-pinion type, and shall have an operating mechanism between the lever and pinion of the type specified. The ram shall be perpendicular to the table surface to an accuracy of 0.025 inch total indicator reading (”iR) per 6 inches of ram travel. The leverage ratio shall be of the manufacture
