How much does the Akira Seiki 5AX-BC650 cost?
Price estimate
We do not have a price for the Akira Seiki 5AX-BC650 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
On the 5AX-BC650, Akira Seiki tilts the table about a B axis and rotates it on C. B swings -50° ~ +110° and C turns a full 360°, with indexing of 0.001°. The table is ∅650 mm (∅25.6 in) and takes 300 kg (661 lb), a larger and stronger table than the one on the 5AX-AC650.
The linear axes are shorter in exchange: 620 mm (24.4 in) in X, 520 mm (20.4 in) in Y and 460 mm (18.1 in) in Z, on roller-type linear guides. All three rapid at 36 / 36 / 36 m/min (1,417 / 1,417 / 1,417 ipm), and the cutting feed rate is given as 20 m/min (787 ipm). Tilting and rotary axis speeds are 25 rpm / 25 rpm.
Spindle drive is where this model differs most from its sibling. It is in-line direct, with a built-in spindle listed as an option, where the 5AX-AC650 uses a belt. The taper is BBT40, the dual-contact form, which helps tool stiffness at the long reaches five-axis work often needs. Peak power is 22.8 HP (17.0 kW) at 12,000 rpm.
The changer is an arm type with 32T and a 2.2 s tool change. Machine dimensions are 3,145 x 3,890 x 2,930 mm (123.8 x 153.1 x 115.4 in), and weight is 10,360 kg (22,840 lb). The maker's page marks coolant tank capacity as to be announced and gives no power requirement.
