Gap Frame Presses

For years, Komatsu has set the industry standard for high performance, low deflection gap frame presses.
 
Available in mechanical or servo, Komatsu OBS and OBW gap frame power presses provide unmatched versatility, accuracy, and reliability.

Komatsu OBS Series - Mechanical or Servo Drive
 

Komatsu has simplified power press operation with their latest line of gap frame presses; the OBS series. Featuring the SIT-II highly integrated terminal, which reduces operator fatigue, lowers operational costs, and increases pressroom safety.

The OBS is extremely accurate with a wide range of tonnage, stroke, bedsize and speed options.
 

  • Balanced center of gravity
  • Thermal balancing between drive section and frame
  • Combination of simple operation and advanced control performance
  • Available in 27.5-220 tonnage capacities

 

Komatsu OBW Series

Komatsu OBW two point gap frame presses require less maintenance than comparable models, reducing downtime. Like the OBS Series, the OBW series is available in mechanical or servo. The OBW's high level of rigidity provides minimal deflection; less than many straight side presses.  

The Komatsu OBW series includes a hydraulic overload protection system designed to prevent damage to the press and dies. Motorized precision slide adjustments are measured in one-hundredths of a millimeter, and displayed on the pendant control panel for easy operation.

  • High quality eccentric drum with high torsion rigidity
  • Multiple-disc wet clutch and brake systems maintains optimal heat balance
  • High precision plunger guide
  • Available in 121-275 tonnage capacities
