How much does the Akira Seiki V4XP cost?
Price estimate
We do not have a price for the Akira Seiki V4XP 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
Akira Seiki's V4XP is the one-metre machine of the V series, with 1,050 mm (41.3 in) of X travel and 560 mm (22 in) of Z above a 1,200 x 480 mm (47.2 x 19 in) table. One caution up front: the maker's page prints the Y travel of this model with millimetre and inch figures that do not agree, so that row is left out of the table here. Confirm Y with Akira Seiki before sizing a fixture.
The spindle is the series' 30 HP class unit. In the V version it is 30 HP (22.4 kW) peak at 10,000 rpm, in the XP version 35 HP (26.1 kW) at 12,000 rpm, with an 8,000 rpm spindle as an option. All are BT40.
A table this long is normally bought for multiple fixtures. Standard loading is 980 kg (2,160 lb) and maximum 1,176 kg (2,592 lb), spread over five 18 mm T-slots. The 28T magazine means one tool list can serve several different parts on the table at once, and each change takes 2.2 s.
Services are 30 kVA and 0.5 MPa (72.5 psi). Accuracy is listed as 0.01 mm (0.00039 in) positioning with ±0.003 mm (±0.00012 in) repeatability. The spindle centre stands 550 mm (21.7 in) from the column cover.
