The 5-axis CNC machining centre BRAM is designed for productive machining of
aluminium and high speed trimming of composites.
High rigidity and speed of the machine ensures precise and time-effective machining.
BRAM was designed with high emphasis on resistance to dust particles of all kinds, and,
subsequently on long life expectancy and trouble-free operation of the machine.

The milling centre BRAM can be equipped with two basic types of
heads: HB662 and HB678 with spindles of output range 12-29 kW
and torque 15-46 Nm. All spindles are cooled with liquid. Types of
tool holders, depending on spindle type - HSK A63 or HSK F63. The
HB678 milling head includes by default spindle positioning
encoder and direct measurement in A and C axes.

Chip Conveyor
For trimming and machining of dust-producing materialsit is possible to select complete ceiling covering by a rollershutter system, which eliminates dust spreading from theworking space of the machine.
For machining of parts from aluminium alloys, in particularmoulds of big dimensions and with longer machining times, itis possible to deliver the machine with a chip conveyor, whichis integrated in the concrete bed plate of the machine and isinstalled under the machine. This solution does not affect thetotal height of the machine. Chip container is placed next tothe machine to enable its convenient and quick discharging.

Probes, measurement and alignment
The machine can be delivered with a tool probe(measurement of lengthand diameter of the tool) and alignment probe(measurementand alignment of the work piece). The measuringfunctions depend on the type of the control system. Thesupports the userand assist in reducing down time. The probes standardlyoffer a lot of preset cycles for automatic setting of thework piece after its clamping, setting of the machiningorigin, reference point, tool measuring, and finalmeasurement of the finished part.
