How much does the Pinnacle BX900T cost?
Price estimate
We do not have a price for the Pinnacle BX900T 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 Pinnacle BX900T is the mill-turn version of the BX900 platform. The Ø800 mm (Ø31.5 in) table is listed at 50(Mill) / 800(Turn) rpm and the built-in spindle takes HSK63T tooling.
Compared with the BX700T, the turning speed is lower, 800 against 1,200, as expected of a larger table, and the linear envelope is bigger: 1,500 mm (59.1 in) of X, 900 mm (35.4 in) of Y and Z of Vertical 1,000 / Horizontal 1,100 mm. Large rings, casings and discs that need turned diameters plus milled or drilled features are the obvious work.
Table load is 800(Mill) / 500(Turn) kg. That figure is lower than the 1,200 kg (2,646 lb) of the milling-only BX900, so heavy 5-axis milling jobs belong on the other variants.
The spindle is rated 19/23 kW (25.5/30.8 hp) and 93/239 Nm (68.6/176.3 lb-ft) at up to 15,000 rpm, with an 1,800±100 kgf draw bar. The spindle centre is 970 mm (38.2 in) from the column. Both rotary axes are direct drive, and rotary accuracy is 10"/10". Rapids are 20/20/16 m/min. The machine weighs 15,000 kg (33,069 lb) and occupies 4,450x4,340 mm (175.2x170.9 in).
