How much does the Akira Seiki SV550 cost?
Price estimate
We do not have a price for the Akira Seiki SV550 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 Akira Seiki SV550 is the entry point to the SV series, the maker's high-speed line. Its BT40 spindle runs to 15,000 rpm with oil chilling and 25 HP (18.6 kW) of peak power, and the axes rapid at 48 / 48 / 36 m/min (1,890 / 1,890 / 1,417 ipm).
Travels are 550 mm (21.7 in) in X, 445 mm (17.5 in) in Y and 520 mm (20.5 in) in Z over a 700 x 400 mm (27.6 x 15.8 in) table. That is the same envelope as the V2XP. The SV550 differs in speed: the V2XP stops at 12,000 rpm in its XP version, and its tool change is 2.2 s where the SV550 takes 1.9 s.
Cutting feed is listed at 24 / 24 / 24 m/min (945 / 945 / 945 ipm), the highest in the SV range and well above the larger SV models. For small aluminium parts, electrodes and light die work, feed and spindle speed together set the cycle time, and this is the SV machine built around them.
The magazine holds 28T. A chain type chip conveyor is listed, with a 250 L (66 gal) coolant tank. The machine weighs 4,099 kg (9,037 lb), stands on 2,845 x 2,200 mm (112 x 87 in) and needs 20 kVA and 0.5 MPa (72.5 psi) air. Control is the AKIRA Mi:845.

Frequently Asked Questions
01
15,000 rpm, on a BT40 taper with oil chilling. Peak power is 25 HP (18.6 kW). The table gives no torque figure, so check the motor curve if the work includes heavy cuts at low speed.
02
Rapid feed is 48 / 48 / 36 m/min (1,890 / 1,890 / 1,417 ipm) in X / Y / Z, and cutting feed is 24 / 24 / 24 m/min (945 / 945 / 945 ipm). Tool change time is 1.9 s.
03
The SV760 is the same machine with 760 mm (30 in) of X travel and a 910 x 400 mm (35.8 x 15.8 in) table. The SV760 weighs 5,189 kg (11,440 lb) against 4,099 kg (9,037 lb) for the SV550. Spindle, feeds and magazine are the same.
04
Dimensions are 2,845 x 2,200 mm (112 x 87 in) and weight is 4,099 kg (9,037 lb). The power requirement is 20 kVA and the air pressure requirement 0.5 MPa (72.5 psi).
