MEGAMILL: Giant milling machine tackles large-format production with power, precision and automation
Designed to handle exceptionally large machining operations with maximum flexibility and precision, Mecof's Megamill milling machine offers not only power and accuracy, but also a level of automation and digitalization perfectly in line with the principles of Industry 4.0.
Like all Mecof models, Megamill can be customized to meet customer requirements. A recently built machine for the aerospace sector is characterized by its impressive axis strokes: up to 42,500 mm in X, with a double crossbeam of 36,000 mm, 8,000 mm in Y for each slide carriage and 2,500 mm in Z for each of the slides. A structure designed to machine large components without compromising stability, rigidity and precision.
Everything is managed by the Siemens Sinumerik ONE numerical control, which ensures maximum reliability and a modern interface, ready to communicate with factory management systems.
Multi-head for every machining requirement
One of the strengths of the Megamill is its versatility in terms of milling heads, which make it a machine that is extremely adaptable to different industrial sectors. Specifically, the machine referenced above has:
- Universal bi-rotary heads with millesimal positioning, 38 kW of power and up to 6000 rpm, perfect for high torque machining. ISO 50 tool attachment.
- Vertical head with offset spindle, ideal for heavy-duty machining, with 2000 Nm torque. ISO 50 tool attachment.
- Milling heads with torque motor and E55 electric spindle, capable of reaching 24,000 rpm and ensuring high-speed machining with HSK 63-A connection.
The package is completed by sliding head magazines, which allow quick and safe changes, and automatic tool changers with 48 positions each, consisting of two overlapping chains with 24 positions and a sliding stroke (tool connection: 28x ISO 50 and 20x HSK 63-A), for uninterrupted operational autonomy.
Automation and digitalization
Mecof's Megamill guarantees Industry 4.0 connectivity for integrated process monitoring and management.
In fact, the optional package with 'Siemens Integrate Access My Machine OPC/UA' allows direct connection to factory systems, facilitating real-time process monitoring. Added to this is the Siemens Omative Adaptive control and monitoring software, which dynamically adapts machining parameters, reducing cycle times and optimising tool wear.
Integrated precision and safety
Laser measuring systems and radio probes for tool and workpiece control, an anti-collision device between the crossbars and automatic top closure, in addition to guide pressurization systems to protect the machine and keep the working environment clean, are all features of the model above.
Cooling and suction: designed for productivity
The dual-delivery cooling system (IRDD40) and 2000-liter filter tanks ensure continuity even during the heaviest machining operations.
On the environmental front, the Megamill is equipped with powerful extraction systems for composite materials such as glass fiber and reinforced carbon fiber, both on the spindle side and on the flat side, ensuring a healthy and efficient working area.
The Megamill is not simply a high-gantry milling machine: it is an advanced machining platform designed for those who need to tackle large-format production without compromise, with the certainty of being able to count on power, precision, automation and connectivity, reducing time and maximizing productivity, according to the company.
