Eckold Kraftformer KF 675 Magnum is the largest and most powerful servo-driven machine in the entire Kraftformer series. This equipment is designed for processing exceptionally large and thick components used in heavy industry. Thanks to its massive construction and servo-control, the KF 675 ensures perfect precision (0.1 mm) and repeatability of results, which is critical for meeting aerospace, shipbuilding, and railway standards.
Purpose: Universal cold forming (shrinking, stretching, straightening, drawing, planishing) of large and extremely thick sheet metals and profiles.
Field of Application: Aircraft factories, shipyards, and railway carriage manufacturing where maximum throat depth and power are required.
Class: Flagship, high-precision, servo-driven Kraftformer with maximum reach.
Advantages and Features
Maximum Power Parameters: The KF 675 Magnum is capable of processing steel (400 N/mm2) and aluminum (250 N/mm2) up to 6.0 mm thick, as well as stainless steel (600 N/mm2) up to 4.0 mm. This makes it the most powerful in the series.
Largest Working Space:
Horizontal Reach (Throat Depth): 675 mm.
Vertical Working Height: 450 mm. These dimensions allow for the processing of oversized panels and components.
Servo Drive with Programmable Precision:
Program Memory: Ability to store up to 25 processing programs, guaranteeing high repeatability in serial production.
Speed Control: Free selection of stroke speed ranging from 150 to 600 strokes/min, allowing for precise control of material deformation.
Adjustment Accuracy: Repeatability of results down to 0.1 mm.
Motorized Upper Ram Adjustment: An adjustment range of 80 mm (with 0.1 mm precision) allows for rapid setup of the machine for any tool or material thickness.
Advanced Diagnostics: Includes electronic fault diagnostics, tool checks (Tool Check), and maintenance interval indicators.
Standard Equipment
Massive, Rigid C-frame: Designed to absorb maximum vibrations and heavy loads.
Servo Drive (6.0 kW): A powerful and precise motor.
Electronic Control Panel: Features a display at eye level for convenient parameter monitoring, program selection, and diagnostics.
Motorized Upper Ram Height Adjustment: Controlled by a servo motor, providing fast and accurate setup.
Quick-Change Tool System: Standard Kraftformer mounting for inserts.
Electronic Stroke Control: Includes an Adjustable Return Position feature.
Options
"Magnum" Full Tool Set: Reinforced and enlarged tools for all types of forming, specifically adapted for thick materials.
Specialized Profile Tools: For complex profiling of beams, tubes, and other structural elements.
Deep Drawing Tools (Doming/Embossing): Specialized tools for creating significant curvature and embossing.
Mobile Control Unit: An additional or remote control block for the operator.
Power Options: Choice of voltage (e.g., 200–240 V or 380–500 V, 3-Phase).
