G996  High performance milling systems

Technological development The G996 is the result of Fidia’s long experience in the field of high performance milling. After years spent satisfying the need for improvement in the quality and accuracy of complex machining, since the launching onto the market of machine tools designed for finishing, Fidia has responded to a new challenge in which the rationalization of the production cycle has become an absolute priority. Combining high dynamics with stability, stock removal with high precision finishing and modular design: the G996 has achieved a new level of performance. The result is a system...

Machine tool structure The large cast iron bed provides a stable support for the moving parts, while the open front ensures wide visibility. The moving components, also made of cast iron, have been designed for high acceleration with no dynamic deformation. At the same time, they ensure the damping capacity required in order to take full advantage of the high spindle torque. The use of spheroidal graphite cast iron and a system of guides with 6 support points for each axis has made this difficult compromise possible. No Foundation Its self-supporting structure allows installing the machine directly...

Dynamics and thermal stability control The kinematics chain is based on rotating nut and fixed ball screw technology on all linear axes. This solution has numerous advantages: JJlarger diameter ball screws; JJreduction of moment of inertia; JJextreme rigidity in motion transmission; JJheat control with coolant flow through hollow ball screws. All the parts generating heat, such as axis motors, nut supports, electrospindles are monitored and cooled by means of a central conditioning system. Furthermore, dedicated sensors measure the ambient and structural temperatures providing an overall monitoring...

The fixed worktable can be replaced by different roto-tilting (RT version) tables (trunnion type), each being particularly well dimensioned for the machining of complex geometrical forms, that are equipped with torque motors bringing the technical characteristics of these solutions to the highest levels of performance. The maximum benefits deriving from the increased capabilities of programming systems on 5 continuous axes are also guaranteed. Interfacing with standardized and modular automatic pallet systems, such as WPM and MP (Multi pallet), reduces down time and allows for full automation...

FMS Flexible Manufacturing System The new FMS system designed by Fidia is equipped with a sophisticated software that optimizes and exalts its operative characteristics. This system is the Fidia answer to the more and more pressing request of increasing the workshop automation level, and integrates a powerful and versatile pallet system shared between more than one G996 machine. The FMS platform serves independent working islands of minimum 2 machines each, and allows for the complete machining of complex components in 3 or 5 axes, starting from the rough part. This system is the ideal solution...

The powerful dedicated software automatically manages and optimizes the production flow without intervention of the machine operator. Such a way of functioning pursues the following goals: JJreduction of waiting times; JJsimplification of programming; JJoptimization of tool wear-out; JJfull monitoring of production flow; JJreduction of human error risks; JJnever-ending 7/7 & 24/24 production. Each machine can be also used in a standalone way, nonetheless granting the normal functioning of the FMS system with the other machines.

Coolant and Chip conveyor Systems Minimum spray mist lubrication for tools is standard, and a swarf collection bin with a large drawer is incorporated in the machine tool bed. Other systems are available as options: JJexternal low pressure lubrication / cooling; JJair blow through the tool centre; JJhigh pressure coolant through the tool centre. Each of these options is provided of suitable chip conveyor and collection system with tanks and filters of various sizes. Dust and mist collection units Machine tool components and the machining environment can be protected by optional dust and mist...

HMS Check and compensate each positioning geometrical error in 5 axis RTCP within the machine working envelope. It consists of a simple and powerful instrument to grant the highest level of accuracy without complex maintenance interventions. The C20 numerical control The Fidia C20 numerical control takes full advantage of the potential offered by combining the performance of the Intel Core i7 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 10 Enterprise 64 bit operating system in...
