The Stamtec GL2 two-point gap frame press (a.k.a. OBG, OBS, OBI or C-frame) with link motion drive technology is designed for stamping large parts or long progressive die parts that require deeper or more complex forming, at high single-stroking rates or in continuous mode, using either blanks or coil stock. The slide is guided by six-point, full-length box type gibs, providing excellent control of slide alignment and accuracy throughout the entire stroke.
With link motion, the slide velocity decreases by up to 40 percent during the working portion of the stroke so the material flows more effectively while the non-working portion of the stroke increases by an offsetting amount to maintain high production rates. The results are better quality parts produced at higher production rates. In addition, the slower speed of the working stroke reduces die impact, punch penetration, snap-through, noise and vibration, thereby increasing machine and die life.
Tonnage Range: 121-286 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 (GL2 Series)
Outperforms conventional presses performing at the same forming velocity by 20 to 40 percent.
Slide velocity slows as it approaches the tonnage rating point by 35 to 40 percent as compared to a convention crankshaft motion (see graph GL2 D-Type to the right).
If off-center loads are applied across the slide, the hydraulic overload system applies full oil pressure where required to maintain parallelism, for consistent stamping quality and longer die life.
