Structure − Structure with fixed portal in ribbed cast iron

with stiffness walls attenuate the torsional stresses

− Cast iron with a high mechanical performance which maximizes structure rigidity and allows optimum harmonic stability and maximum damping during demanding cutting conditions

− Machine secured on foundation with weight equally distributed over fixing points enabling extreme rigidity and a very high geometrical stability

− Modular design allows maximum flexibility in machine configurations to adapt to the technical requirements of the customer

Linear axes − Preloaded ballscrews − Preloaded bearings to remove inversion

backlash and axial stress on ballscrews enabling a high quality of surfacing

− Roller guideways on the X, Y and Z permitting high travel speeds, and excellent stability of the movement

− Automatic grease lubrication of ballscrews and bearings minimising the pollution of coolant and the consumption

Table − Swivelling rotary table fixed on cradle and moving

along the X axis for higher rigidity − Excellent approach to the workpiece on its 5

faces thanks to the swivelling of the table − Travels are optimized to offer an important

distance under the spindle nose − Direct measurement on each rotating axes with

absolute encoder

Spindel − Powerful spindle with high torque allowing high

metal removal rates − Direct coupling of the motor on spindle for a

better transmission of the forces − Spindle body designed to facilitate accessibility to

the workpiece during the 5-axis machining

Environment - Ergonomics − Evacuation channels for chips equipped with

washing device − Complete safeguard ensuring safety of the

machine, the operator and environment − Accessibility to the machining area from top and

side of the machine and possibility to load with crane

− Opening of the panels is simplified for an easy maintenance

− Operator panel

The Umill range is a 5-axis machining centres with a portal structure and a swivelling rotary table on cradle.

Its modern design and compact size are optimized to guarantee a minimal footprint without compromising the fundamental characteristics of the HURON machines : enhanced rigidity for high performance and quality machining.

This range is ideally suited for complex parts in 3 or 5 axes, from roughing to finishing, for various sectors such as high precision mechanical parts, automotive, rail, energy, machining of 3D forms, or aerospace.

Spindle speed 10.000 rpm Power (S1/S6) 12 / 26,2 kW Torque (S1/S6) 115 / 250 Nm Characteristic speed 1.000 rpm − Direct drive for higher positioning accuracy and less

maintenance. − Guiding by ceramic roller bearings to reinforce rigidity and

increase spindle life ; less vibrations and decrease of functioning temperature.

− Lubrication of bearings with grease which do not require any maintenance.
