SKY Series

Series of simultaneous 5-axis machining centers ideal for machining patterns and moulds, especially in aluminium.

Belotti SKY cnc centres are particularly suitable for milling light alloys patterns and moulds, resin prototypes for design centers and for trimming structural components in composite materials.


The Belotti SKY Series is the ideal solution for the production of moulds and patterns in aluminum and composite materials, designed to respond above all to specific applications in the automotive and aeronautical sectors.
Belotti SKY cnc machining centers have a monolithic structure, complete with internal ribs and thermally stabilized to increase machining precision and stability over time. The Belotti patented fork head, compact and rigid, is equipped with torque motors and hydraulic locking brakes on the rotary axes, which guarantee a higher degree of surface finish during the simultaneous machining of the linear axes interpolated with rotary axes A and C. The total protection enclosures, the vision cameras in the spindle housing for the verification of the work cycle and the monitoring of unattended machining, the suction system with motorized hood and the cooling liquid system with filters and chip conveyor for the processing of high volumes of aluminum (also available in the special version for composite materials), are optional elements that contribute to the maximum cleanliness and safety of the working environment.
