Machining centres for mass transportation equipment manufacturers

Added to MTDCNC by Asquith Butler Ltd on 14 March 2014

The Mubea Mega-Flex five-axis machining centre is a unique twin gantry machine and has a bed length of up to 60 metres and is designed for the machining of large panels, such as those found in the transport and aerospace sectors, particularly the high speed rail industry. The specially designed machine also incorporates a patented “Double X Axis System and Vertical Clamping System” which allows local clamping around the machining area and thus improving component rigidity whilst high speed machining of apertures such as window and door openings.
Mubea Systems manufacture a complete range of 4- and 5-axis CNC machining centres, specially designed for automatic setting of exceptionally long aluminium and steel profiles. With this product offering, it increasingly tailors to the needs of customers in the fast-growing mass transportation market. Looking to provide these clients with unmatched accuracy, precision and performance, Mubea Systems has found a solid solution in Siemens’ SINUMERIK 840D sl control system.

The machine can be equipped with two gantries, which each have a five-axis spindle head of up to 44 kW and a 36 position toolchanger, can operate in tandem or as separate X-axes to maximise the machine’s dynamics when machining large aluminium panels measuring up to 3500 mm wide by 1000 mm high (1500 mm option). The innovative vertical clamping system on each gantry ensures that the panel is securely clamped under the machine spindle at all times, and to ensure that the profile is machined exactly to the drawing the probing routine automatically compensates for any distortion in the panel.
The spindle heads have axis movements of +/- 110 degrees in the A-axis and +/- 225 degrees in the C-axis and is capable of handling tools up to 700 mm diameter, such as circular saw blades.  Mega-Flex also features Siemens 840D CNC control units, one at each gantry, which can operate the two gantries independently or in tandem depending on the parts being machined, for example two heads working on one large panel, or in a pendulum-type operations with the table split between different components.  The array of clamps along the machine table are positioned automatically by gantries and up to 32 clamps can be specified.
The current investment in railway infrastructure and recent announcement of a major order for roiling stock to be built in the UK for Crossrail and the potential of HS2 is welcome news. Mega-Flex was developed for the machining of large panels and the capacity of the machine means that an entire railway carriage side can be machined in one piece.

The Mubea range of machines are exclusively available in the UK and Ireland from Asquith Butler Ltd. Asquith Butler other exceptional levels of knowledge regarding large capacity machining centres and coupled with their unrivalled levels of service and support provide a unbeatable package for today’s demanding customers.
