Performance Technology Power Accuracy

KX Large, a range of very high performance milling machines for 5-sided and 5-axes machining of complex parts. The choice of fixed portal architecture makes it possible to offer a machine with maximum rigidity for extremely accurate machining in various and hard materials.

High accuracy performance in positioning and in 5 axes contouring. Wide distance between columns for the maximal exploitation of the part volume. The modular design and the many alternatives and equipment offered make it easy to meet all customer requirements. This excellence range offers models suitable for the tooling production sectors molds, dies, models, machining of large parts for general and precision mechanics, or production of complex parts for the Aeronautics or Energy.

Structure of KX 50 Structure of KX 300 Structure of KX 100 / KX 200 Rigid and robustness Linear axes X axis: moving table on fixed bed structure Y axis: moving saddle on fixed transverse Z axis: vertical slide equipped with an adjustable milling head with 2 orthogonal axes and an electro-spindle. This design allows the cutting tool to work on high machining parameters, even with hard materials, and at high speed. Z-axis balancing cylinders. Linear guide rails with roller recirculating roller bearings allowing feedrates up to 40 m/min. Servo motors: the linear axes are driven by AC motors coupled directly to the end of the precision ball screw. Absolute measurement scales on all axes.

Rotating axes The B C axes are equipped with a direct mounting angular encoder and offer high positioning accuracy. Direct drive by torque motors for perfect synchronization with linear movements. This motorization offers the advantages of continuous high speed, high acceleration, high rigidity, absence of backlash, and wear. High clamping torque in roughing. Allows high-speed machining in 4 and 5 simultaneous axes.

Environment - Ergonomics Numerical controller Chips evacuation channel with washing device and spiral conveyors. Chips evacuation by coolant liquid. Tool magazine outside of working area. Full safeguard ensuring safety of the machine, the operator, and its environment. Connections and communication interfaces integrated and easily accessible. High memory and calculation capacities. Interactive programming. Graphic simulation before machining for optimal safety.

Maintenance Very good accessibility to all maintenance points. Grouping of fluid, pneumatic, electrical components in a common cabinet.

Large Series Fork head and standard electrospindle Accurate positioning and repeatability for complex workpieces. Angular encoders in the axis for accurate positioning and repeatability. Torque motors for dynamic movements without backlash and wear. High clamping torque for high roughing. Possibility of reaching negative angles. Axial and radial tool stiffness guaranteed. Machining of deep pockets thanks to the use of long tools. Spindle and machining secured thanks to vibration monitoring.

HURON numerical controller cycles This cycle provides automatic tool checking during machining or at tool change. If critical wear or a broken tool is detected, the system automatically triggers the replacement of the tool at the most appropriate time. It, therefore, safeguards the integrity of the workpiece and the cutting tools and optimizes tool use.

Main features:

Full use of available spindle power

Automatic feedrate modulation

Maximize material removal rate

Spindle and rotating axes overload protection during roughing

No change to the NC program

Implemented by HURON

Configurable wear and breakage detection tolerance for each tool
