Very high performance 5-axis machining centres

KX Five (5-axis) machining centres enjoy the benefits of Huron�s expertise in the design and manufacturing of high-speed milling machines. This range of very high performance machines is suited to roughing and finishing work in five simultaneous axes and on five faces and meets all the technical and economic challenges facing engineering companies in the Aeronautics, Automotive, Medical and Energy sectors with regard to reducing process times and cutting manufacturing costs. Performance levels in roughing, finishing and precision work enable the toughest productivity targets to be met in terms of machining complex parts, such as injection moulds, aeronautical components or parts used in precision mechanics. The architecture of the K3X 8 Five high-speed 5-axis milling centre consists of a fixed gantry and bed and a 500 mm diameter table that rotates (C-axis, 360°) and tilts (A-axis, -30°/+180°) and can take up to 250 kg. It is therefore capable of machining in five continuous axes on five faces. As the table on this new generation “8 Five” is inclined in a 55° plane (instead of 45°), negative machining angles of up to -20° can be reached. Consequently, the angle of the spindle axis in relation to the table ranges from 0 to 110° compared with 90° for the previous generation. The combination of dynamics and precision on this machine results in the production of very high quality surface finishes. With its standard spindle reaching a speed of 24,000 rpm with a torque of 40 Nm for 25 kW, it has a high maximum chip-forming capacity. This milling centre also offers the advantage of great accessibility with good visibility of the work area. Heavy workpieces can easily be lowered from above the machine thanks to the generous openings in the enclosure.

Power, Speed and Precision... for more than one application! To fulfil the expectations of the most demanding customers, Huron has developed the MX line of multifunctional milling centres. These highly flexible centres can, in a single setup, perform the most complex machining operations in five axes and on five faces, from roughing to finishing, by milling or turning. The MX series is available in several versions. Essential criteria such as excellence in performance, reduced production times, the most compact machine footstep, full machine automation, and optimization of the customer�s investment by providing an �All-in-One� machine make this line a �must-have� in terms of cutting-edge technology. Its high-spec cast-iron moving column structure increases machine rigidity and dampens the vibrations produced by cutting forces in the toughest materials. Rigidity and geometric stability are reinforced by the equal-load ground anchor points. The linear axes are equipped with ballscrews with an expansion compensation system. Low-friction roller bearing shoes are provided for the guideways. Automatic greasing of the ballscrews and shoes reduces cutting fluid contamination considerably. The table is equipped with a torque motor. High locking and holding torque and the rigidity of the design mean that high power can be used for roughing work. The torque motor-powered head is mounted on a 45° plane enabling it to be tilted from -45° to +180°. Excellent spindle characteristics (torque, power and speed) ensure maximum chip-forming capacity on roughing, and outstanding precision and machining quality on finishing contours and profiles. The machining vibration monitor ensures safe work for the machine components and the tool. The MX is equipped with a 48-slot tool magazine as standard. This is installed outside the work zone. The machine has a full enclosure for complete protection of the machining zone, the operator and its environment. The door opening provides comfortable access to the table and workpiece. Furthermore the optional palletizer helps reduce idle time by loading/unloading workpieces as a background task. The model shown is the MX 10 MT. This is a milling/turning version which can machine parts weighing up to 2000 kg, with 1200 x 1200 x 1000 mm strokes and a two-position palletizing system with a 1000 mm diameter turning pallet. The table rotates at a speed of 500 rpm with a design offering very high acceleration rates. The milling head is a �fork� type (optional) with a single axis of rotation. The B-axis, parallel to the Y-axis, can be used to tilt the spindle around a horizontal axis. The axis comprises a torque motor linked directly to the rotating parts to ensure play-free travel and highly accurate positioning.

For quick and easy milling! Years of High Speed Machining experience have resulted in the creation of the SX series – small machines dedicated to the fast machining of mass-produced small parts. The bed/gantry structure with a cross saddle travelling along the three linear axes guarantees a high level of precision and dynamics by limiting the masses in movement which lie outside the work zone. This configuration is perfectly suited to the small and medium-scale production of precision components. Rigidity is ensured even at high speed by the roller guideways on all axes. The sloping wall bed design helps discharge swarf effectively to the conveyor at the rear of the machine. The SX 6 axes travel 500, 400 and 400 mm. A perfectly integrated automatic workpiece changer rotates the work zone in four seconds. The changer has two 650 x 400 mm tables with a dimensional capacity of 375 (D) x 500 (L) x 450 (H) mm and a load capacity of 300 kg for the workpiece. The changer is activated by hydraulic devices for rotation and locking. A Hirth gear coupling guarantees excellent rotational positioning accuracy. This design helps meet productivity requirements by eliminating idle times on workpiece loading and unloading. It can be mounted on a production line or in a machining cell. It can be combined with a workpiece loading/unloading robot interface for continuous, fully automated operation without supervision. The standard version of the SX is equipped with a 16-slot disc-type tool changer with very fast tool change times of the order of 1.5 seconds. The basic 12,000 rpm electrospindle with its 50A HSK attachment is the heart of the machine. The thermal stability of the spindle is perfectly controlled by cooling equipment. Due to its outstanding acceleration, maximum speed is reached within one second, helping to reduce machining time. Space availability is no longer an issue thanks to the small footprint of these machines, making the SX 6 an ideal model for small production shops.
