Eckold Kraftformer KF 340 belongs to the medium series of motorized forming machines. Its primary difference from the KF 324 lies in its significantly increased power and, most importantly, the infinitely variable (stepless) adjustment of the working speed (strokes per minute). This ensures optimal working conditions for any material or process—from slow, precise correction to rapid curvature forming.
Purpose: Universal cold forming of sheet metal and profiles, including shrinking, stretching, correcting, straightening, planishing (smoothing), and drawing.
Field of Application: Aerospace and automotive (especially restoration), railway carriage construction, shipbuilding, and high-precision metalworking shops requiring maximum flexibility with various material thicknesses.
Class: Motorized universal machine with medium reach and adjustable speed.
Advantages and Features
Infinitely Variable Stroke Speed (220–600 strokes/min): This key advantage provides unsurpassed versatility:
Low Speed (220 strokes/min): Ideal for forming thicker materials (e.g., 3.0 mm steel), for straightening, leveling, or precision finishing.
High Speed (600 strokes/min): Accelerates stretching, doming (curving), and planishing processes, increasing productivity.
Increased Forming Power: The KF 340 offers up to 50% more power compared to the KF 324, allowing for work with steel up to 3.0 mm thick (compared to 2.0 mm for the KF 324).
Optimal Working Space:
Horizontal Reach: 340 mm.
Vertical Height: 245 mm. These dimensions ensure comfortable work with medium-sized parts, the standard for most bodywork.
Universal "All-rounder": Due to its compatibility with a wide range of Eckold tools (for shrinking, stretching, planishing, profiling, etc.), the KF 340 is the ideal workshop machine capable of performing nearly all operations.
Electromechanical Drive: A reliable and powerful motor that ensures constant forming force.
Pedal/Handwheel Control: A combination of foot control (to activate the stroke) and a handwheel (for precise tool position adjustment).
Standard Equipment
KF 340 Machine: Stationary, massive C-frame with electric drive.
Speed Control System: Intuitive interface for infinitely variable stroke frequency adjustment.
Ram Position Adjustment: System for precise adjustment of the ram height.
Stand/Cabinet: Robust floor stand providing stability during work with thick materials.
Quick-Change Tool System: Mounting for rapid replacement of Kraftformer tools.
Options
Full Tool Set: For shrinking, stretching, doming, leveling, punching, and notching.
Specialized "No-Mar" Tools: Featuring inserts made of soft materials for working with sensitive surfaces.
Optional Foot Pedal: For controlling the work cycle.
