New Servo Presses for Sale • Komatsu Servo Stamping Presses

New Komatsu Servo Presses

A servo press is a mechanical stamping press driven by a servo motor instead of a flywheel and clutch. Because the motor controls the slide directly, you can program its speed and position through every stroke: slow it down through the forming zone, hold it at the bottom, or run short partial strokes for shallow parts. We sell new Komatsu servo presses alongside about 850 used presses, so you can compare a new servo press with a used OBI or straight side press in one quote.

S, L and H in the model names are versions of the same press with different specs; each listing shows its full stroke, shut height, bed size and speed.

Servo Press vs. Flywheel Press

Why Choose a Servo Press?

• Better parts in hard materials. Slowing the slide through the draw helps high-strength steel, stainless and aluminum form without splitting or springback problems.
• Less die wear and noise. A slower approach and impact means less shock on the die and a quieter press.
• Faster changeovers and tryout. Save a motion profile for each die and call it up at setup; inch through a new die at any speed.
• One press for more jobs. Run blanking at full speed and forming at a slow, controlled speed on the same press.
• Energy. With no flywheel to keep spinning, the press uses power mainly when the slide is moving.

How to Choose a Servo Press

• Gap frame or straight side. The H1F gap frame series is open on three sides for easy die setting; the H2W straight side series has two points for long progressive dies and off-center loads.
• Tonnage. Add up every operation in the die plus a safety margin of about 20% to 30%.
• Stroke and shut height. Enough stroke for part lift and draw depth. On the H2W, the S version has the longer stroke for deeper draws and the H version a shorter, faster stroke for shallow parts.
• Bed size. Right-to-left and front-to-back room for your die and clamping.
• Feed line. Pair the press with a servo feed that keeps up with the press speed.

Servo Press FAQ

What is a servo press?

A mechanical press driven by a servo motor. The motor replaces the flywheel and clutch, so the slide speed and position can be programmed through the whole stroke.

Is a servo press a mechanical press or a hydraulic press?

A mechanical press. It still uses a crank or linkage to move the slide, like a stamping press, but with a servo motor in place of the flywheel. It gives some of the motion control of a hydraulic press at mechanical press speeds.

What is a servo press used for?

Forming and drawing, high-strength steel and aluminum parts, progressive dies that need different speeds for different jobs, and parts with tight tolerances.

What does pendulum or partial stroke mean?

The slide moves back and forth through only the part of the stroke it needs instead of making a full rotation, which raises strokes per minute on shallow parts.

Are these presses in stock?

Some are in stock and some are made to order. Each listing shows its status; your salesperson can confirm lead time and options.

Do you sell used presses too?

Yes. We keep about 850 used presses in stock, including Komatsu presses, so you can compare new and used.
