How the machine works
Flexible production
The core breaker is especially useful for smaller batches and changing castings when rotation or vibration is unnecessary.
Safe operation
The casting is positioned in its fixture and the cycle starts via two-hand control. The process and equipment are described below.
Kernbrecher 605
Compact, flexible core breaking.
The casting is held between the hammering unit and the counterholder. Impacts transmitted into the component break up the sand core. Released sand and core fragments fall down through the casting openings. The open design provides easy access to the working area.

From casting to released core sand
Load and position
The casting is brought into the working area manually or by crane. The holding arrangement is adapted to the geometry and suitable contact points of the component.
Apply hammering impulses
The proven F+K hammering unit performs the decoring operation. The workpiece is held between the tool and the counterholder while the transmitted impacts break up the sand core.
Discharge sand and unload
Released sand falls down out of the casting. The component is then unloaded. The appropriate configuration is selected for the casting and the decoring task.
Features and benefits
Varying castings
Decoring down to pilot runs without changing tools, depending on component geometry and suitable contact points.
Stationary hammering unit
The machine performs the hammering instead of manual decoring. This relieves operators of vibration exposure from a handheld decoring tool and can substantially reduce decoring times.
Two-hand control
The machine is equipped with safety two-hand control. The exact equipment is adapted to the application.
Manual or crane loading
The open construction is suitable for crane loading and facilitates changes between different castings.
Stroke by configuration
The hammering unit offers up to 300 mm stroke depending on configuration. The illustrated version has a KE605 with a 200 mm stroke.
Optional sound insulation
A sound-insulated configuration is available as an option. The illustration shows the open machine.
Define your decoring task with us
Geometry, dimensions, weight, core structure and required quantities determine the configuration. Together we assess suitable contact points, loading, stroke and optional sound insulation.
