Imagine, total control of slide velocity, multiple stroke depth positions and dwell—all without loss of energy and accuracy in microns. The Komatsu H1F servo press delivers nearly 3 times more working energy than a conventional mechanical press – but consumes over 30% less electrical energy! The H1F series is also available in solid frame design (“O” frame) for applications where angular deflection is critical. In capacities from 39 to 220 tons, the H1F presses are in stock and ready for immediate delivery. Schedule a die tryout today!

The H1F Servo -driven Press

Designed for Superior Flexibility and Accuracy

Ideal for progressive, transfer or manual die operations

Incorporates modern, state of the art A.C. servo technology into mechanical stamping press designs

Ability to control slide velocity throughout the stamping work being done-optimal slide motion can be set for any application

Maintains constant working energy throughout stroke regardless of slide velocity

Provides ability to dwell at position to allow timing of secondary work within the press cycle time

Improved part quality

Increased die life

Ability to program multiple motion paths before returning to top dead center

Automatically maintain and adjust slide position to assure consistent die height

Elimination of high maintenance mechanical components like the clutch-brake unit

Reduces importance of die or part lubrication

Reduces die tryout time and expense

Saves energy cost by reducing electricity consumption

Komatsu offers a complete line of straight side presses from 121 tons to 4000 tons, with slide connections from single point to multi-point and multi-side. Frame designs from solid, 1 piece unitized body to full tie rod construction, all with wide windows to utilize the full width of the bolster for maximum flexibility. Every Komatsu straight side press features a plunger guided slide for a guaranteed minimum 30% longer die life, “keyless” splined power shaft connections, hydraulic slide lock to eliminate slide “creeping”– causing die height changes in heavy blanking operations, and force-cooled hydraulic clutch & brake for virtually maintenance free operation and the highest single stroke rating in the industry. Press drives are available in eccentric or link motions, with precision helical gearing hardened and ground running in oil. Rounding out this press system is Komatsu’s own SIT-II press control with 100-job memory and “built-in” automation features as automatic single stroke operation mode, programmable die protection, 2-channel electronic load monitor, and interfaces for both light curtains and for coil line.

At Komatsu, high performance should not be optional.

The economical straight side with no compromise on performance. For jobs requiring larger beds for tooling, but lighter tonnage. Solid frame construction.
