Aluminium profile CNC machining centre: multi-axis milling, drilling and tapping of long extrusions
Long-bed profile machining centres · 3 to 4 axes, tool magazine, 18,000–24,000 rpm spindles, 4 to 7 m X travel, shuttle zones
An aluminium profile CNC machining centre is a long-bed machine that holds an extrusion in pneumatic or servo vices and works it with a spindle that changes tools from a magazine and, on 4-axis machines, swings to machine faces at an angle. Before asking for prices, fix the longest bar and largest section, the faces and angles that need machining in one clamping, and how loading is overlapped with cutting.
CNC machining centres with tool magazines for milling, drilling, tapping, notching and sawing aluminium and thin-walled profiles, in 3- and 4-axis versions with long beds and multi-vice clamping. Dedicated drilling machines with fixed drill units are covered on the Aluminium profile drilling machine page; double-head mitre saws, end-milling machines and copy routers are outside this page.

Three published machines show the range: DEMAC's CNC aluminium profile machining centre has 4000 mm X, 510 mm Y and 400 mm Z travel with a 0° to 180° A axis [1]; Bluetek's 4-axis GS4Z-CNC-7000 has process ranges of 7000 mm X, 1200 mm Y and 300 mm Z [2]; Onustec's C640 is a gantry design whose beam is driven by a linear motor. [3]
DEMAC lists axis speeds of 80 m/min in X, 60 m/min in Y and 30 m/min in Z, an A-axis speed of 130°/s and positioning accuracy of ±0.05 mm in X, ±0.03 mm in Y and ±0.02 mm in Z. [1] Bluetek lists 60, 40 and 30 m/min for X, Y and Z, a machine size of 11,350 × 2400 × 2550 mm and a weight of 4500 kg. [2]
Editorial calculation: at the stated X speeds, a full X stroke takes about 3 s on DEMAC's machine (4000 mm at 80 m/min) and 7 s on Bluetek's (7000 mm at 60 m/min); on a bar with features at both ends, ask for a cycle time on your part rather than comparing rapid rates alone. [1][2]
Bluetek's machine has double worktables so two profiles can be loaded and machined alternately without interfering, and Onustec offers two separate working zones for shuttle operation as an option. [2][3]
Give the supplier the alloy and temper, longest bar, section envelope (width, height), wall thickness, every feature with its face and angle, batch size, and whether you need shuttle loading.

Plan the angles, tool magazine and clamping
Onustec describes its 4-axis C640 as performing routing, drilling, tapping, thread milling, notching and sawing while the profile bar stays stationary, with all tools at angles continuously adjustable from -95° to +95°, and an optional angle head for machining from below so that five sides can be reached in one clamping. [3]
The C640 carries a 12 kW spindle at 24,000 rpm and an 8-position tool magazine that can hold a 150 mm T-slot saw blade for end milling transom profiles; an automatic tool sensor reads tool length, and an auto clamp avoidance system moves the vices when they conflict with the tool path. [3] DEMAC's machine has a 9 kW spindle at 18,000 to 24,000 rpm, a 6-tool magazine and six clamps, each driven by its own servo motor. [1] Bluetek lists a 7.5 kW spindle at 18,000 r/min within 13 kW total power. [2]
Editorial note: the number of vices, how they are repositioned and whether the program avoids them automatically decide how much of a long bar can be machined without re-clamping; ask the supplier to show the clamp layout for your longest part.

Buyer questions
How long a profile can these machines take?
DEMAC lists 4000 mm of X travel and Bluetek's GS4Z-CNC-7000 lists 7000 mm. [1][2]
What does the fourth axis do?
It angles the spindle: DEMAC lists an A axis of 0° to 180° and Onustec tilts all tools from -95° to +95°. [1][3]
What spindle do profile machining centres use?
The reviewed machines list 7.5 to 12 kW spindles at 18,000 to 24,000 rpm. [2][1][3]
