FFG Italo-Taiwanese partnership yields jointly-developed VMCs
FFG Europe has introduced the two lines of vertical machining centres that are said to be the result of the first common industrial project between Italy’s Sigma Technology and Feeler, a unit of Tiawan’s Fair Friend Group (FFG).
The machines will be produced at the new Feeler plant in Taichung, Sigma said, adding that the units combine both Feeler’s experience in large-scale production and Sigma’s expertise in the manufacturing of high-performance vertical machining centres.

The partnership’s Alliance range of 3-axis VMCs is said to be designed for the automotive, mould-making and general engineering sectors. The range includes two models (S and M), both with a monolithic cast-iron structure, X-axis travels of 800 and 1,000mm, a Y-axis travel of 520mm and a Z-axis travel of 505 mm, with integrated box-type tracks for rapid speeds of up to 30 m/min.
The supplied spindle is said to guarantee torque of up to 95Nm and power of up to 15kW, with a rotation speed of 12,000 rpm. The disc tool magazine is available with a capacity of 24 standard pockets (a 30-pocket model is an option), with random tool selection and a double gripper exchange arm, Sigma explained.
The company noted that the partnership’s Typhoon 5A 5-axis continuous VMC features a single-arm tilting joint (A-axis) and support of the integrated rotary table with a diameter of 600mm (C-axis). According to the supplier, the machine is available with X-, Y- and Z-travels of 460, 520 and 400mm for rapid speeds of up to 30m/min. The spindles work with a torque of up to 108Nm and power of up to 17kW and 15,000 rpm.
According to Sigma, the machining centre is especially appropriate for the production of moulds and dies, prototypes and for applications in the general engineering sector.
In addition, the A- and C-rotary axes are operated by water-cooled torque motors. The units also feature pressurised optical scales on all of the linear axes as well as absolute rotary encoders on the two rotary axes to ensure precision, the manufacturer reported.
