Reason 1:
Komatsu's NEW Type 6 Gap Frame, Air Clutch Presses (that WE sell) holds the line on prices.  We all know that price increases are overdue. To give you Komatsu quality at a lower cost, Type 6 presses, from 80 to 200 ton no longer have plunger guides. This group of presses use a superior, new, front to back crankshaft design  that Komatsu has introduced in the last few years.

Komatsu Servo Hybrid Presses INCLUDE plunger guides and sealed oil lube system. Companies that own Type 3 presses have profited from the plunger guide for years.

A Servo Hybrid Press costs more than a Type 6 but you get the plunger guide system which doubles ram guiding.

Reason 2:
Komatsu Servo Hybrid Presses do not have a flywheel, clutch, brake or dual solenoid valve. ALL of these HIGH MAINTENANCE items are gone! The cost of these parts went toward the servo system. Money well spent.

Reason 3:
Komatsu Servo hybrid presses have no flywheel that causes press frame misalignment. This is the BIG flywheel problem that you never noticed. See PressTech 2006.pdf  below for our explanation and save the cost of a flywheel.

Reason 4:
Komatsu Servo hybrid presses average stopping time of 80 milliseconds. Since there is no clutch to disengage, no brake to engage and no compressed air to exhaust (or pay for) these presses stop in less than HALF the time of the best air clutch machines! Die protection systems work better, you run faster with zero die damage. Save $.

Reason 5:
Did you think Servo presses were so expensive that you could not justify the cost? The smallest servo press that we sell is the H1F-35. Maybe you could run small dies, TEST die sections and learn what the technology teaches you about your tooling. The little machine has a plunger guide, sealed oil lube system and a nice self locking power ram adjust system. Set up quicker and get SUPERIOR die life.

Reason 6:
Komatsu Servo Hybrid Presses hold dead bottom point accuracy to +/- .0004 inch, regardless of frame heat build up. Actually, the servo system runs "closed loop" on ram position. You can turn it off if you don't want active compensation. Would more uniform forms, draws and coining help your bottom line?

Reason 7:
Controlled speed at part contact allows metal to extrude rather than break out. This makes better parts with less noise and less harmful shock that beats up your die, press and floor.

Reason 8:
Have you considered a link drive press for slower forming speed? What if you bought one and found that it did NO GOOD? Komatsu Servo Hybrid Presses allow you to program a link drive speed profile that does your work the best. You can even pause on the bottom like a hydraulic press. Next, save a new job with totally different speeds. Even shorten the stroke. One servo press does the work of many different types. Versatility, blank, draw and form in the same press.

Reason 9:
Storing energy in a flywheel comes at a cost. First you have to maintain a clutch and brake system to get the energy out. Next, you can run out of stored energy and not finish forming your part! Plus, the huge chunk of inertia, roughly 1/3 the weight of the whole machine, imparts it's influence on the press frame. Our servo motor only runs when you make a part. It draws only enough (electrical) energy needed to make the part. Unlike a flywheel, it will not run out of stored energy.

Crane Production Systems Corp. set up a Komatsu H1F-60 Servo Hybrid press in our shop, in Waukesha, Wisconsin. Here is what it looks like with a Wintriss SmartPAC2, Shadow Light curtains and CWP servo feed all integrated together. Yes, Wintriss SmartPAC2 runs on servo presses.
