New Komatsu OBS Type 61 Gap Frame Large Single Pointe Mechanical Press Series Standard Features:
Frame and Bolster
Engineered quality. While most gap presses are associated with a greater level of deflection, the Komatsu series brakes the stereotype by maintaining the lowest deflection available. No matter what size of job you spec with a Komatsu, there is no compromise to the characteristics of the frame or the accessibility to the bed area. The highly rigid frame, slide and bolster combine to hold all deflection characteristics to a minimum, setting the new industry standard.
Clutch and Brake
Productivity and reliability. The wet, multiple disc clutch and brake provides higher single stroke operation rates throughput while providing quicker stopping time in all modes of operation. The unit is housed in a continuous-lube, separate oil bath from the main drive, providing superior heat dissipation capabilities. No maintenance operations are normally required, other than an annual fluid change.
Heavy-Duty Slide Construction
A heavy single-piece cast steel slide is used for increased rigidity. The slide construction is true box-type with narrow flanges and standard provisions for tooling attachment. A motorized slide adjustment with digital display is standard. The die height is displayed in metric units of 0.01mm for precise slide adjustment. The slide is guided primarily by the plunger guide mechanism along with full-length, six point gibs. The precision of the plunger guide and gibbing is a true advantage with tooling, allowing tight tolerance between the punch and die.
Hydraulic Overload Protector
Helps prevent damage to the press and dies. All Komatsu presses are equipped with a hydraulic overload protector, a feature that has been standard for decades helping to protect against damage to the press. If the rated load is exceeded, the press stops automatically. Since the hydraulic pressure can be released easily, operations can be resumed smoothly even if jamming occurs.
SIT IV – System Integrated Terminal
Advanced electronics technology provides user-friendly operation and outstanding reliability. The SIT IV electronic press control unit is designed to provide the fastest, easiest, and most reliable control available for all press functions. Included as standard equipment on the Komatsu OBS press, SIT IV incorporates all the latest thinking in press control unit design.
- All information necessary for press set-up, start-up, operation and diagnostics is available in one display, at the touch of a button.
- Language terminology and graphics are user-friendly, easily understood by the press operator in plain view in one central location on the digital display. Display also includes plain language description of fault messages.
- SIT IV has the ability to integrate with current press room equipment, such as electronic coil feeds.
- Operator “T-stand” control interface houses all switches and push-buttons required for ordinary press set-up and operation, including a button for slide adjustment.
- Die Data Recording function can store and retrieve data for 10 dies, including cam and fault detection angle as well as production performance. Also includes digital display of “stored” press speed and actual press speed, plus crank angle.
- Alpha-numeric entry of die name and memo data for easy cataloging and referencing.
- Digital Total Counters
- 1-Production, re-settable
- 1-lot (pre-set), re-settable
- 4 – Electronic rotary cams
- 1 – Pneumatic air ejector with cam
- Mode Selections: (1) Off, (2) Inch, (3) Single Stroke, (4) Continuous
- Optional Modes: (1) Automatic Single Stroke, (2) Automatic Continuous
Simple guidance. SIT IV displays operational procedure guidance for select press functions. Intuitive, user-friendly prompts guide press operators in a logical series of steps, for faster, more reliable press set up and operation.
Extensive use of electronics gives outstanding reliability.
- Solid-state control
- Integrated Circuits are used for all control circuits
- Cross-checking duplex circuits for clutch brake control are use on each stroke (patented)
- Increased safety, longer operation life and high reliability
Digital display for improved operation performance. Digital display of the crank angle and electronic angle detectors provide increased accuracy for press operations. Automatic operation setting and die set-up functions are easier an faster for press operators, with precise, reliable settings every time. To protect the integrity of all electronic systems and provide additional safety, monitor lamps indicate defects in circuits of all electronic systems, and faults are detected instantly.
New Komatsu OBS Type 61 Gap Frame Large Single Pointe Mechanical Press Series Optional Features:
- Electronic Load Monitor (2-channel) Load monitors are available to continuously monitor loads in all press operations, including blanking, bending, drawing, etc. The monitor also detects die overloads and underloads during operation. In addition, balanced die load is achieved by measuring the off-center-load, thus extending press and die life.
- Emergency Stop Receptacle
- Die Cushions
- Vibration Isolation Pad
- Slide Knockout (mechanical)
- Quick Die Change Equipment
- Hydraulic die clamps available in either lever or cylinder type.
- Hydraulic die lifters.
- Mechanical draw out rails (note: re-machining of “T” slots may be required)
- Presence-Sensing Safety Devices
- Additional set of 4 Electronic Rotary Cams
- Air Ejector with Cam
- Quick Die Change Interface

- Increased Job Storage Memory
Warning – For protection of the operator, point of use guards should be used at all times. Komatsu presses do not include O.S.H.A. recommended point of protection guards.
Note – Brake monitor and control reliability. This control meets the current requirements of O.S.H.A. Standards Section 1910.217 and ANSI B11.1.
