How much does the Campro CNV-850 cost?
Price estimate
We do not have a price for the Campro CNV-850 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Campro CNV-850 is the general-purpose size in the CNV series of linear-guide vertical machining centers. It travels 850 mm (33.4 in) in X and 520 mm (20.4 in) in both Y and Z, over a 950 × 520 mm (37.4 in x 20.4 in) table that carries 500 kg (1,102 lb).
This is where the series moves to a heavier casting. The machine weighs 5,000 kg (11,023 lb), against 3,300 kg (7,245 lb) for the CNV-750. T-slots change to 18 mm, five of them, and the arm type magazine goes to 24 tools with 20 as the alternative. The spindle center is 630 mm (24.8 in) from the column.
What stays light is the drive train. Campro states that all axes have precision linear guide ways and direct drive servo motors with couplings, and that Z has no counter-balance. Rapids are 30 m/min in all three axes. The spindle is an 8,000 rpm No.40 taper unit with 7.5 / 11 kW (15 HP), and higher speeds of 10,000, 12,000 and 15,000 rpm are options.
Campro also builds a box-way machine with this X travel. The CPV-850B weighs 6,000 kg (13,227 lb), carries 800 kg (1,763 lb) and has an 11 / 15 kW (20 HP) motor, but its rapids are 20 m/min. The CNV-850 is the quicker and lighter of the two, and the better fit when parts are small-to-medium and cycle time matters more than depth of cut.
It needs 15 kVA and a 2,930 × 2,260 mm (115 in x 88 in) floor plan. The spindle nose range is 110~630 mm; the inch figures Campro prints for that row are inconsistent and are left out.
