Available in the UK and Ireland from official importer, sales distributor and sales agent TDT Technology, the Fidia D321 boasts a large working envelope of 3,000 by 2,200 by 1 100mm in the X, Y and Z axes and a compact footprint of just 6,000 by 6 000 mm. In addition, the wide-opening front door is ideal for loading large and heavy workpieces, while offering high visibility.
Configured as an ‘upper gantry’ type machine with a moving cross beam, this design is proven to be the most qualified for stiffness and dynamic accuracy. A 3,000 by 2,000 mm cast iron, T-slot table is fastened to the floor and can accommodate loads of up to 20 tonne.
Fidia’s M5B/22 bi-rotary indexing head is equipped with a 2 2kW, 30,000 rpm HSK50E spindle that is ideal for the semi-finishing and finishing of plastic injection moulds, as it combines compactness with high rigidity. Moreover, the use of a Hirth coupling with 3° step/pitch on the B and C axes allows for high precision, even when using long tools to access difficult-to-reach mould features. B-axis travel extends from +24 to -102°, with C-axis travel from +180 to -177°.
Fidia’s M5C/35 milling head is a 35 kW, 20,000 rpm HSK63A grease-lubricated spindle. This fork-type unit is tough and adaptable to a wide range of materials, including steel, aluminium, foams and composites. High resolution direct encoders on the A and C axes grant accuracy even for the most delicate and demanding operations. The Fidia NC control supports continuous 5-axis interpolation and compensates tool centre position, according to the spindle inclination. A-axis travel extends from +95 to -110°, with ±200° in the C-axis.
Fidia’s D321 offers 24 m/min axis speeds and 3 m/s² acceleration in the linear axes, along with a 20- or 42-station automatic toolchanger. Tool lubrication and cooling takes place through an air-oil system using a minimum quantity of non-toxic vegetable oil. Air blow from the outside of the spindle can also be deployed. Grease lubrication is applied automatically to the recirculating ballscrews, guides and slideways.
Among the many options available are tool life management software, probing, automatic laser tool pre-setting, chip conveyors and various environmental accessories such as mist collectors and dust extraction devices.
