Cylinders are I he heavy-duty, non-binding guides of a K-Series maintain mounted to large, keyed backing plates which, in turn, are maximum contact with extra long, hardened-steel slideways interlocked to the side housings to provide true centerline throughout the stroke range. Ground slide surfaces are loading. Tapered, pre-loaded, wedge-type keys are set in designed for high-pressure grease lubrication with cast iron place with the press under full load to ensure "zero clearance" guides or a non-metallic (Turcite@) lining, depending on between these major components and to prevent any model, size and/or application. Clearances can be readily movement during operation. Forces are transferred by adjusted externally. means of keys and interlocks through parent metal to deep T side housings.

When the ram is tilted, spherical pressure eliminate high stress concentrations and provide maximum discs transmit the force of the piston concentrically above bearing surfaces for downward, as well as upward, or the pivot point, while the gibs remain in perfect vertical stripping loads. alignment.

Clearance around the lower studs permit a vastly increased by the more than ample distance between ram tilt of 1" in 10 feet in either direction with absolutely no the side housings. This area is often a critical factor when binding of the slideways. working with long material, but with a K-Series the greater ratio of distance between housings to overall length is a real advantage not always available on many press brakes. 3 -< Pacif ic The Industry's Most Advanced Press & Shear COM PACT, H I G H -S P E ED HYDRAU LI C SYSTEM Tn" t"t"rt and most advanced hydraulic technology is reflected in the functional design of every K-Series power unit.

CYLINDER AND PISTON DESIGN Tne cylinOers on a PACIFIC@ K-Series are heavy, cast, single-piece, domed-head cylinders which eliminate high stresses and potential oil leakage areas on the high pressure side of the cylinder. Bores are honed and polished to 16 micro inches. The cylinders are double-acting, with an extra large area under the piston to provide additional ram support capability. P,rron, and rods are one-piece, wear-resistant, class 40 castings, honed and polished to 16 micro inches. Rods are either non-metallic or bronze guided, depending on press model, to insure long life with minimum packing wear. The oil retaining rod surfaces are an aid to proper lubrication. MODULAR STACKED VALVES B.."r." the valve system of a hydraulic is the heart of the press, all valves on a K-Series are designed and built by PACIFIC@ to assure their operating characteristics of being completely compatible with the press brake itself. PACIFIC@ valves, unlike most commercial, "off-the-shelf" valves, provide improved accuracy and the special pressure and directional control characteristics necessary for two- cylinder hydraulic press design. Poa,a,at-built, heavy duty valves are specially designed for long, rugged service with a minimum of maintenance. They are "stacked" in modular form to eliminate inter- connecting piping and to avoid the necessity of a massive, heat producing, manifold block. 4 And Dependable Hydraulic System AUTOMATI C D ECOM P RESS I O N SYSTE M Controtled Power Release is a standard feature of all K-Series Press Brakes. lt is a feature that provides decompression of the oil in the main cylinders belore the ram starts its return stroke. This reduces the high-velocity, uncontrolled return shock when working on jobs having a large build-up of stored energy typical of high strength steels with a considerable amount of spring back. TEMP ERATU RE COM PENSATED AM PLI FI ER LEVEL CONTROL Pacitic's Amplifier Level Control System provides the fastest and most accurate ram levelling response of any press brake available. This advanced system is responsible for the great repeatability of the K-Series Press Brakes. lt senses and automatically corrects variations in ram level as small as .001" with resulting overall machine level accuracies measured in thousandths of an inch. T I he system incorporates two amplifier valves, a level controlvalve, and a steel leveltape.
