K Range High performance milling systems Giving shape to design

Years of investment in research and development have led to Fidia’s success in the high-speed milling sector right from the early 90s. A reduction in machining times and hand finishing is the most significant result, to which may be added the possibility of working with very hard materials, simplifying production cycles and producing parts just one set-up operation. Only specifically designed machine tools can guarantee, at the same time, high feeds, accuracy and surface quality. The K211 and K411, Fidia’s high-speed milling centres, are used in the production of moulds and dies for the...

The criteria used to determine kinematic chain are such as to grant excellent performance in terms of removal capacity, accuracy and speed. Design attention was focused on achieving a compact bi-rotary head with high removal capacity, continuous movement of the axes and powerful hydraulically operated clamping systems. Axis morphology of the KR, and Y2K make these models particularly suitable for the machining of larger pieces. A rotary table is used on the KR version integrated, as an alternative to the fixed table, with the axis of rotation positioned in the proximity of the external...

Technical solutions Fixed bed structure The choice of a fixed bed structure was determined by the following criteria: JJconstancy of the forces independently of the weight of the workpiece, allowing for optimum milling quality; JJoptimum visibility of the part being machined; JJwide range of possibilities for customization. The “high bed” version allows for a reduction in the moving masses giving superior dynamic performance. The bed is made in cast iron, while the mobile parts of the equipment of the 3 axes are made of steel in order to obtain the best mass-rigidity ratio. The fixed cast...

Tool magazine and tool presetting Chain magazines coming in different tool numbers are housed in the machine bed, suitably protected from swarf and coolant. Tool measurement, by means of a laser probe, is done while spindle is in rotation: length, diameter and tool shape are therefore checked under real operating conditions. Also available, measure and verification of special tools: ■ multiple cutting areas; ■ angular heads; ■ advanced ID Chips management. Dust suction unit An adequate cleaning system protects the machine components as well as its working area. The system efficiently...

HSK63A Continuous bi-rotary head Series K machine tools are provided with continuous, powerful, compact birotary heads. A and C axes can machine both through-high-dynamics-continuous interpolation, and through the positioning mode, with the operator interactive command. In case of heavy duty removal operations, the axes can be stiffly clamped by means of powerful hydraulic brakes. Fidia head, equipped with a built-in spindle driven through a synchro motor, is provided with servomechanisms (automatic backlash recovery), and it is able to perform 0.001° resolution positionings for any type...

The C20 numerical control The Fidia C20 numerical control takes full advantage of the potential offered by combining the performance of the Intel Core i3 and the RISC Power PC processors. It is conceived to manage the most sophisticated high speed applications running at 5 axes with RTCP. It is equipped with Windows® 7 Ultimate operating system in multitasking mode. Simple and reliable machining The C20 is equipped with a 19” TFT video and thanks to its HI-MILL 3D CAM and ISOGRAPH 2½D CAD/CAM it directly imports CAD mathematical models in IGES,VDA-FS, DXF, DWG formats, enhancing but at the...

Cinematic chains with refrigerated motors, ball-screws and bearings prevent from thermal drift anomalies.

KR199 A remarkable increase of the operating volume is obtained by integrating rotary tables guided by a NC management of the 6th and 7th axis. The coordinate systems always refer to the piece being machined in any allowed position. The 5-side access to the part to be machined, and the prearrangement for pallet systems are KR199 main advantages.

KR211 KR214 Machining of large dies and extra-dimensioned components are carried out efficiently by the KR configurations. The use of the 6th axis as rotary workpiece table guarantees max accessibility from all sides. Head and table combined rotations are automatically handled by the NC by rotating the system coordinates. In just one placement it is possible to operate on a such working area that is usually offered only by bigger gantry machines.

K711 K714 - K1011 K1014 The modular design of X axis bench allows for wide stroke extensions. K series are ideal for the machining of narrow/long size, structural components, made of light alloy, typically requested by the aerospace sector. The rack/pinion system guarantees an excellent dynamics for the X axis, whatever the length. COOLANT TANK

Y2K Fidia’s experience as a unique supplier of global solutions has made this special configuration possible. It consists in the combination of two basic systems sharing the same work-piece table. Productivity is therefore doubled compared to a traditional portal machine. Furthermore, the extremely flexible software gives excellent results when machining dies, large dimensioned single components or when directly approaching separate pieces. This is achieved thanks to the fact that the 2 NCs allow for independent and different milling part-programmes ensuring total safety for each machine’s...
