TKE  944

Mobile gantry 4-axis CNC machining centre for drilling, milling and tapping, at any angle from -90° to +90°, on profiles and plates with a thickness up to 10 mm if made of aluminium, lightweight alloys and PVC and up to 2 mm if made of steel. The moving part of the machine consists of a gantry with precision rack and pinion drive. The 8,5 kW electrically-driven spindle with ISO 30 tool holder allows machining operations, including heavy-duty work, with optimum results in terms of speed and accuracy. The machine can be used in double mode (7000 model) so as to minimize machine downtime, as it is possible to change the workpiece (load/ unload) and the automatic setting of the vices in "concealed" time. It is also possible to load and consequently machine different workpieces between the two work areas. The automatic tool magazine for 4.000 mm version is available in a fixed solution on board the machine with 4/8 places, recommended for single place machining. Otherwise a 12-place automatic magazine on board the carriage, ideal to allow a faster tool change and useful for the double mode machining, is available. The 7.000 version is supplied with the 12-place automatic magazine on board the carriage. The gantry is provided with a guard which, besides protecting the operator, also reduces the noise impact on the environment.

12-place tool magazine
The machine can be equipped with a 12-place automatic magazine installed on board the carriage moving on the X-axis. This configuration replaces or supplements the 4/8-place fixed magazines on the left-hand side of the machine. This solution, required to perform machining in double operation mode, considerably reduces the tool change times and consequently increases the machine productivity and efficiency.

Vices

The vice unit can ensure the correct and safe clamping of large aluminium, steel and light alloy profiles. The vice size and the long Y stroke of the electrospindle allow machining large profiles for all kinds of civil and industrial applications. Each unit slides on special linear guides on machine surface. The positioning is managed by the X axis. Counterblocks can be mounted quickly and accurately, making the machine extremely versatile. The vice unit is available optionally in double hold-down device version to machine two profiles in parallel.

Electric head
8.5 kW S1 high torque electrospindle allows heavy duty machining. The electrospindle movement along C axis allows performing rotations s from - 90° to + 90°and working on 3 sides of the profile with no need to reposition it. It can be used both with some types of extruded steel and with aluminium profiles, thanks to the lubrication system with oil emulsion spray mist or, as an option, with minimal diffusion oil.

Profile positioning

The machine is equipped with two sturdy and precise pneumatic reference stops, used to machine one or two profiles in multi-piece or double operation mode (model 7,000 only). A laser system is available for accurately positioning the workpieces on the work surface; it reads each profile and sets the reference without the need for mechanical stops.

Additional vices (Optional)

If necessary, it is possible to install additional vices beyond the standard machine equipment. In this way, it is possible to ensure perfect clamping of bars or bar sections even in complex cases in terms of number, size or types of profiles to be machined. Moreover, the additional vices allow greater versatility in vice position depending on the length of the workpieces and the machining to be performed.

Dimensional profile measurer (Optional)

The machine can be optionally equipped with an electronic device that automatically corrects workpiece dimensional errors in length, width and height. In this way, the accuracy of the machine is not influenced by the differences between theoretic and actual workpiece dimensions during machining. This device accurately probes the rough workpiece in several positions, correcting the machining along its whole length, even with deformed or warped profiles.
