End milling machines Graule AKF 1, AKF 4/200, AKF 6/250, and AKF 6-S for transom profiles

The AKF end milling machinery is tailored for machining transom ends on aluminum architectural profiles. Double-ended ball bearing spindle supports eliminate radial deflection during cutter contact, ensuring clean surface matching across structural window junctions.

Milling cutter arbor mounted on dual precision ball bearings ensuring vibration-free profile milling
Eight-position revolving turret depth stop allowing rapid reset across various profile series
Quick-change tool arbor holding shaped cutter head stacks with diameters reaching 250 and 300 mm
Pneumatic horizontal and vertical profile clamping cylinders preventing workpiece distortion

Dual-blade notching saws Graule AS 450, AS-U 450, and AS-P 550 for curtain wall framing

Graule AS notching saw systems feature vertical and horizontal saw blade heads to cut stepped notches into structural profiles. The machines are essential for manufacturing architectural facades, winter gardens, pyramid roof skylights, and complex polygonal joinery.

Independent depth adjustment mechanisms for both horizontal and vertical circular saw blades
Stepped notch cutting inside structural curtain wall mullions and transoms at customized angles
Rigid swiveling fence bars and vernier measurement scales ensuring accurate setup angles
Manual balanced feed motion or optional hydropneumatic power traverse across working strokes

Modular roller conveyors Graule RO, RLK, RLH, and electronic length stop systems RLE

Graule modular roller conveyors are built in standard configurations for light profiles and heavy ST-60 variants for wide structural beams. The RLE electronic positioning stop with digital readout allows rapid adjustment of workpiece cut lengths without manual tape measuring.

Modular conveyor sections spanning multiple meters equipped with leveling floor support stands
Durable polymer or galvanized steel rollers supported by sealed ball bearings for heavy loading
RLE electronic digital stop incorporating magnetic linear tape scales and precision sensor heads
Flip-away mechanical stop flag allowing continuous feeding of lengthy aluminum and wood beams

Tool carriage assemblies, hydraulic dampers, drive belts, and tooling for Graule machines

Maintaining factory precision across Graule machinery requires regular replacement of wear-prone kinematic components. We assist with selecting linear ball bushings, feed damping hydraulic cylinders, carriage return springs, and spindle drive belts using the machine nameplate data.

Linear motion ball bushings and protective wiper seals running along ground tool carriage rods
Hydraulic feed control brake cylinders featuring stepless speed throttling across sawing strokes
V-belts and ribbed drive belts engineered with elevated tensile stability against operational heat
Protective clear safety shields, rotary stop arms, pneumatic directional valves, and arbors

Machine building background and engineering principles of Graule equipment

German machinery manufacturer GRAULE Maschinenbau GmbH in Aalen has dedicated decades to developing and manufacturing industrial equipment for machining aluminum, timber, and structural polymer profiles.

A primary engineering foundation across Graule machines is the deployment of heavy iron alloy machine beds engineered to relieve internal stress naturally.

This rigid foundation absorbs cutting vibrations during heavy profile processing and preserves tool guide alignment through years of continuous multi-shift fabrication cycles.

Kinematics and precision guide rods of ZS radial arm cross-cut saws

The ZS series radial arm pull saws including models ZS 85, ZS 135 N, ZS 170 N, and ZS 200 N/NF rely on a precision linear traverse assembly.

The tool carriage travels along two induction-hardened, precision-ground cylindrical steel guide rods supported by recirculating ball bushings with integrated dust seals.

This configuration ensures parallel blade travel and enables compound miter cuts up to 25 degrees horizontally and 45 degrees vertically with smooth hydraulic feed braking.

AKF series end milling machinery for precision transom and mullion jointing

Milling transom ends and facade mullion joints demands high cut accuracy to ensure tight profile connections without gaps.

On Graule AKF end milling machines, the cutter spindle arbor is supported by paired precision ball bearing journals, eliminating runout when shaped cutter heads enter thick-walled aluminum extrusions.

A quick-change spindle arbor accommodates multi-step cutter stacks up to 250 and 300 mm in diameter, while an eight-position turret stop accelerates profile changeovers.

Notching technology for structural curtain wall framing on AS dual-blade saws

Fabricating glazed curtain wall facades, skylights, and bespoke architectural conservatories requires stepped notches at compound angles. Graule AS series notching saws feature two interconnected circular saw blade assemblies arranged in vertical and horizontal orientations.

The operator adjusts cutting depth and stroke independently using graduated scales, while pneumatic clamps secure the workpiece to form precise corner joints in structural mullions and transoms.

Modular roller conveyor systems and RLE digital electronic positioning stops

Workshop throughput in profile preparation relies on material handling mechanization around primary saws. Graule roller conveyors span standard RO and RLK versions with polymer or galvanized steel rollers alongside heavy RLH and RO-ST60 models built for large structural beams.

The RLE electronic positioning stop utilizes a magnetic measurement tape and digital display sensor, while a flip-up stop finger enables feeding long sections without manual measurement errors.

Maintenance guidelines and replacement component selection for Graule machinery

Maintaining factory cut tolerances and preventing workshop downtime requires scheduled servicing of Graule machinery.

Key focus areas include cleaning tool carriage guide shafts, monitoring ball bushing seals against metal chips, inspecting drive belt tension, and checking hydraulic brake fluid levels.

Our technical team assists with selecting replacement bearings, clamping cylinders, protective shields, and return springs matched to the machine nameplate for dependable plant operation.
