BRAXL


The 5-axis gantry-type machining centre for themanufacture of big patterns, moulds, cutting of plasticpressings from vacuum presses, etc. The machinedmaterials include alloys of aluminium, non-ferrous metals,composites, plastics, epoxy etc.

Dimensional variants of machine travel in X,Y,Z

axes:

Travel (mm)

X-axis 3000 - 50000

Y-axis 2000 – 6000

Z-axis 1000 – 3000

DESIGN

After welding, all parts of the frame from thick plates areannealed and then machined on 5-axis machining centresand checked by a measuring device. This guaranteesdimensional accuracy and geometric fidelity of individualparts and thus of the whole machine. The frame structurehas been optimized by finite element method for thecalculation of dynamic load, and the drives have beendesigned accordingly.

The 5-axis machine (5 NC axes: X, Y, Z, A, C) is equipped with a precision automatic swivelhead HB 710. The head is standardly equipped with an electromagnetic locking system forfixing of the A and C axes, which is used in particular in the indexed machining of Al alloys.Per order it is possible to deliver the head with HEIDENHAIN absolute measurement.

Types of work tables

Work table from hardened KARTIT

Universal work tablefrom hardened KARTITwith M10 threadsin raster 100 x 100 mmis particularly suitablefor machining plastics,composites and woodpatterns. Universalclamps are mostly usedfor the clamping.

CAST IRON work table

Universal work tablefrom cast iron with crossT-slots for standard T-nutssuitable in particular formachining materialsfrom aluminium alloys. Inaddition, it enables quickand precise clamping ofvarious clamping devices,machine vices, indexingheads, turntables, etc.After rough machining, itscasting is subject tostabilizing annealing andfinishing. This guaranteesits straightness, precisionand long-time shapestability.

Vacuum table -KARTIT

Vacuum work table canbe used wherevermachining of platematerial which can beclamped by means ofsuction devices orshaped templatesprevails. Work top withintegrated distribution ofvacuum, square grid forvacuum fixtures,mounting threads M8 forclamping special fixtures- this all enables for theuser to resolve clampingof any work piece.

ALUMINIUM work table

Universal ALUMINIUMwork table with threadsM10 in raster 100 x 100mm is particularlysuitable for machiningplastics, compositesand aluminium alloys.

Tools can be changed in two ways. Manual toolchange is suitable for manufacture, wherein thetools are changed in longer time intervals.Automatic change is suitable in all other cases.The tool changer also includes the TOOLMANAGER program options according to the typeand possibilities of the control system.

The machine is standardlydelivered with theHEIDENHAIN iTNC530HSCI or SIEMENSSINUMERIK 840D SL controlsystem. The choice of thesystem depends on thequalification of the machineoperators and their usualpractice.

Innovations

Master-SlaveThe machine constructionallows using so-called"double gantry" on X and Yaxes (Z-axis - preloadedball-screw – absence ofplay). Those are electricallypreloaded pinions on therack, one against another.This provides forelimination of play betweenthe rack and the pinionduring machine reversing.

Integrated AET (Air Exhaust Turbine)It exhausts hazardous dust and chips which arise in machining compositesdirectly from the tool.

Linear guide coversLinear guides of X, Y, Z axes are covered by bellows fromvarious materials according to the production nature. Thebellows ensure protection against penetration of dust andchips onto linear guide, including carriage. The Z-axisguides are equipped with both-side dust wiping.

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.The supports the userand assist in reducing down time. The probesstandardly offer a lot of preset cycles for automaticsetting of the work piece after its clamping, setting ofthe machining origin, reference point, tool measuring,and final measurement of the finished part.

Machining of composites

For composite machining the machine with HS 710 head canbe equipped with integrated AET for exhaust directly fromthe cut. The exhaust capacity is supported by an axialexhaust turbine, which has sufficient suction power forexhausting chips directly from the cut. The exhaust nozzleterminal must be adapted to the tool length and diameter.The following figure shows the exhaust principle.
