Price estimate
We do not have a price for the Akira Seiki SV1630 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 SV1630 puts a 15,000 rpm spindle over a 1,750 x 800 mm (69 x 31.5 in) table. Travels are 1,630 mm (64.2 in) in X, 850 mm (33.5 in) in Y and 815 mm (32 in) in Z, and the machine weighs 12,575 kg (27,723 lb).
It is the first of three large SV machines, and several things change at this size. Tool length capacity rises to 350 mm (13.8 in), which the SV1350 and the models below it, held to 250 mm (9.8 in), cannot match. The accuracy class moves to 0.015 mm (0.00059 in) positioning and ±0.005 mm (±0.00020 in) repeatability. The coolant tank grows to 640 L (169 gal).
The spindle itself is unchanged: BT40, oil chilled, 42 HP (31.3 kW) peak. So is the 36T magazine with its 1.9 s change. Rapids are 36 / 36 / 30 m/min (1,417 / 1,417 / 1,181 ipm).
Who needs high speed at this size? Makers of large aluminium parts, pattern and model shops, and mould shops finishing big cavities with small ball-nose cutters, where surface speed depends on rpm. The table is rated 2,300 kg (5,071 lb) standard and 2,760 kg (6,085 lb) maximum. Dimensions: 5,100 x 3,540 mm (201 x 139 in). Supply: 35 kVA. Chips: chain type conveyor.
