Akira Seiki RMV250RT

Q: How much does the Akira Seiki RMV250RT cost?

The price estimate for the Akira Seiki RMV250RT is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/akira-seiki-rmv250rt#price; the request is passed to Akira Seiki or an authorised dealer.

Overview

A ∅250 mm (∅9.8 in) tilting rotary table and a BT40 spindle make the Akira Seiki RMV250RT the larger of the maker's two multi-face production machines. The table rotates 360° on C, swings +30 / -120 on B and carries 60 kg (132.28 lb).

Travels are 500 mm (19.69 in) in X, 250 mm (9.84 in) in Y and 400 mm (15.75 in) in Z, and the spindle nose stands 125~525 mm (4.92~20.67 in) from the table surface. Against the RMV160RT, every axis is longer and the table takes three times the load.

The move to BT40 widens the tool range to 75 mm (2.95 in) in diameter, 200 mm (7.87 in) in length and 4.5 kg (9.92 lb). HSK63 is optional. A servo 24T+1 magazine is standard and 40T+1 can be ordered. Expect a slower change than on the small machine: 1.9 s tool to tool, 3.4 s chip to chip.

Spindle power is 12 HP (8.9 kW), or 15 HP (11.2 kW) in acceleration, and the speed row on this model's page reads 15,000 rpm as an option. Rapid feed is 48 / 60 / 72 m/min (1,889 / 2,362 / 2,834 ipm). Listed accuracy is 0.012 mm (0.00047 in) positioning and ±0.005 mm (±0.0002 in) repeatability. The machine weighs 5,000 kg (11,023 lb), measures 1,900 x 2,677 mm (74.8 x 105.39 in) and requires 25 kVA.
