The Stamtec G2 series two-point gap frame press (a.k.a. OBG, OBS, OBI, or C-frame) is designed for stamping relatively long, narrow parts at high single-stroking rates or in continuous mode, using either blanks or coil stock. The G2 series provides a large die area at a very economical price and can run progressive dies that need the longer bed area. The slide is guided by six-point, full-length box type gibs, providing excellent control of slide alignment and accuracy throughout the entire stroke.
Tonnage Range: 121-275 Delivery Time: 18-20 weeks
Stamtec presses can be customized to meet a wider range of SPM, stroke, rating point (BDC), bed and other specifications and dimensions.
Parallelism: Slide to Bolster - .001" per foot or less
Deflection: .0015" per foot or less R to L & F to B with 2/3 of the bed symmetrically loaded.

Press Advantages:
Press Advantages - 2-Point Gap Frame Press (G2 Series)
Extra-long, box-type centered gibs guide the slide during the working portion of the stroke. This design provides full control of left-to-right and front-to-back slide alignment.
Heavy, one-piece welded steel frame is fully stress relieved and designed to resist deflection, providing more accurate stampings and longer die life.
Fast-response hydraulic overload relieves the pressure of a tonnage overload in milliseconds, stopping the press immediately and protecting press and dies from damage.
