MDL Series

Advanced high-speed machining centers ideal for the automotive and aerospace industries.

Belotti MDL 5-axis cnc centers are used with great versatility for milling
patterns and moulds in light alloys and can be utilized for trimming large-size structural parts in composite materials.


The MDL Series is an advanced high-speed 5-axis CNC machining center that ensures maximum productivity in milling models and prototypes and finishing large-scale moulds and aluminium/composite parts for the aerospace industry.
The adoption of 5-axis heads equipped with torque motors, optical lines on linear axes and structures with very high rigidity enhance the precision characteristics and finishing quality of the machining.
The options available to ensure optimal cleaning conditions and safety of the working environment include:

  • total enclosures
  • vision cameras in the spindle housing for checking the work cycle and monitoring unattended machining
  • suction system with motorized hood
  • lubricating-coolant system with chip evacuator

Fork head up to 50kW

Belotti patented 5-axis head for very high precision during machining operations. This model is provided with an electrospindle up to 50kW and allows the tool orientation in any direction. It is equipped with a scale inductive type measuring system which grant high dynamic and accurate performances.
The head is also equipped with a hydraulic rotary axis locking system, which allows a higher machining rigidity when interpolation is not required.

Total enclosure with moving roof

The total enclosure, made of sound-absorbing panels, is designed to guarantee compliance to the current European noise rules for machining centers.
The automatic upper doors have a suitable opening for loading of parts through bridge crane.
Manual lower doors have a wide opening to enable loading of pieces according to the machine strokes.

Upper rolling shutter

Motorized rolling shutter that limits the escape of chips from the workstation area, making the opening and closing task easy and quick and allowing the overhead travelling crane loading.
The special translucent fabric guarantees ample light in the work area, already artificially illuminated.

Cooling liquid system with chip conveyor

Coolant system complete with chip conveyor, liquid collection tank with mechanical filter fabric purifier and high- and low-pressure pumps.

Double bridge

The second independent bridge is the ideal solution to increase the cnc center productivity and flexibility.
It can be equipped with the same spindle as the first head or with a different one.

Vision cameras

Dedicated cameras set on the spindle housing to verify the working cycle and monitor unattended machining
