The automatic tool changer includes:

• a tool magazine
• ISO30 tool holder tapers
• ER32 collets
• a 9 kW spindle with automatic tool change
• a controller card capable of managing automatic tool change

Operation:

When a tool change is necessary, the spindle automatically positions itself above the tool magazine to deposit the current tool holder and pick up a new one. The tool holder consists of an ISO30 taper at its upper part and a chuck (ER collet) that clamps the milling cutter at its shank. The taper is held to the spindle by a valve controlled by a pneumatic system. Once the tool holder is fixed, an automatic measurement of the new tool’s length is optional: the spindle positions itself above the automatic probe to descend in Z until it touches the tip of the milling cutter. Machining can then begin.

Automatic tool change requires a pneumatic supply to allow the tapers to be held on the spindle. A compressor is necessary and requires the following minimum capacities (power: 5.5 kW (7.5 HP); volume: 1000 L; pressure: 0.8 MPa (8 bar); flow rate: 0.7 m³/min).

Rectified steel table with T-slots for high-precision machining of heavy workpieces.

The vacuum table holds workpieces by suction without the need for clamping devices.

The vacuum table includes:

• a honeycomb table
• 4 to 12 independent vacuum zones manageable by valves
• aluminum T-slots for workpiece clamping if necessary
• suction hoses under the table
• gate valves on the side of the frame to control table zones
• a manometer to measure the pressure of each pump

The vacuum pump includes:

• a vacuum pump
• a suction system
• an air filter
• a silencer
• a safety valve
• a soft starter
• a thermal safety relay
• a manual and automatic control system

The pump creates a vacuum at the vacuum table. We offer vacuum systems between 2 kW and 7 kW of power. The vacuum pump is powered in single-phase for 2 kW models or three-phase for 5 kW and 7 kW models.

The chip extraction system includes:

• a vacuum cleaner
• a collector
• a hose
• a hose support
• a manual and automatic electronic start system
• a suction nozzle with brush at the spindle (with automatic lift on machines equipped with automatic tool change)

It extracts and collects chips and dust generated during machining. An advanced version of the chip extractor uses a cyclonic system coupled with a filter to recover fine particles down to 3 µm.

To ensure the reliability of our systems, LUQUE Machines equips its CNC routers with DSP controllers or fully integrated control panels. These controllers integrate the program reader and trajectory calculators internally within the machine. In addition to improving reliability and precision, these interfaces are simpler to use.

The micro-lubrication system sprays micro-droplets onto the workpieces and tool to lubricate, cool, and capture dust during machining. You can spray water, cutting oil, or just air.

The micro-lubrication system includes:

• a cutting fluid reservoir
• an adjustable spray nozzle
• a cutting fluid flow rate adjustment system
• a spray pressure adjustment system
• a liquid collection tray can be added to the table

Pneumatic positioning stops on the vacuum table allow plates to be consistently positioned in the same place during series machining.

The 4th rotary axis includes a chuck, a tailstock, and an adapted control card capable of managing a 4th axis. It allows for milling the workpiece in rotation.

The tangential and oscillating blade includes a spindle fixed to the gantry capable of moving cutting blades. It allows for cutting flexible materials.

The loading table automatically loads panels onto the milling machine table. This system allows for complete machine autonomy on a production line.

It is also possible to add an unloading table for machined parts or a robotic arm to perform this operation.

Laser safety barriers are a safety element. This system stops the machine if a person or object enters a delimited area around the milling machine.

The complete machine enclosure isolates the milling machine to protect the environment from chip projections, dust, fumes, noise, accidents…

An emergency stop system can be added in case of door opening.
