How much does the Pinnacle DU1412 cost?
Price estimate
We do not have a price for the Pinnacle DU1412 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 DU1412 is a 5-axis double column machining center that mills and turns in one setup: a 45° swiveling spindle head works over a Ø1,200 mm (Ø47.2 in) direct-drive rotary table that spins at up to 600 rpm. Linear travels are 2,200 mm (86.6 in) in X and 1,400 mm (55.1 in) in Y, with Z listed as 900 mm (35.4 in) with the head vertical and 800 mm (31.5 in) with it horizontal.
The rotary table is the unusual part. Pinnacle embeds it in a 2,200x1,200 mm (86.6x47.2 in) rectangular table with T-slots, so a long part can be clamped across the whole surface, and supports it on a hydrostatic bearing. The rectangular table takes 5,000 kg (11,023 lb); the rotary table is rated for 3,000 kg (6,614 lb). A curved-teeth clutch at the front end of the spindle fixes it for turning tools, and the taper is HSK T63.
The built-in spindle reaches 15,000 rpm with 19/23 kW (25.5/30.8 hp) and 93/113 Nm (68.6/83.3 lb-ft), continuous and S6 60% ratings. Those are finishing and semi-roughing figures for a machine of this size, better matched to aluminium structures and mould surfaces than to heavy steel roughing. The head tilts from -30° to +180° on a direct-drive A axis at 50 rpm, and both rotary axes carry encoders.
Standard equipment listed for the DU1412 includes a Heidenhain TNC640 controller, kinematic and DCM anti collision software, linear scales on 3 axes, coolant through the ballscrews and a 30T arm type ATC. The table gives magazine capacity as 30(60)/40(80) under a DISK/CHAIN heading, with tools up to 300 mm (11.8 in) long and 8 kg (18 lb). Linear positioning accuracy is listed as 0.005, in millimetres. Pinnacle's table has no rows for machine weight, floor space or power supply, so those have to be requested.

Strengths & Limitations
Strengths
- Ø1,200 mm (Ø47.2 in) direct-drive rotary table on a hydrostatic bearing, running at up to 600 rpm for turning
- 45° swiveling head with a direct-drive A axis covering -30° to +180°
- 15,000 rpm built-in spindle with 19/23 kW (25.5/30.8 hp) and an HSK T63 taper
- Rectangular 2,200x1,200 mm (86.6x47.2 in) table around the rotary table carries 5,000 kg (11,023 lb)
- Linear scales on 3 axes, rotary encoders on A and C, and DCM anti collision software are listed as standard
Limitations
- Spindle torque is 93/113 Nm (68.6/83.3 lb-ft), light for roughing steel on a machine with 2,200 mm (86.6 in) of X

Frequently Asked Questions
01
Yes, according to Pinnacle's description. The rotary table is supported by a hydrostatic bearing system and runs at up to 600 rpm, which the maker calls a turning function, and a curved-teeth clutch at the front end of the spindle fixes it for turning operations. The rotary table is Ø1,200 mm (Ø47.2 in) and rated for 3,000 kg (6,614 lb).
02
X is 2,200 mm (86.6 in) and Y is 1,400 mm (55.1 in). Z is listed as 900 mm (35.4 in) with the head vertical and 800 mm (31.5 in) with it horizontal. The spindle nose sits 150~1,050 mm (5.9~41.3 in) above the table, and the door opening is 1,400 mm (55.1 in) wide.
03
The DW1422 on the same page is the three-axis machine of the pair. The DW1422 has an ISO 50 spindle at 8,000 rpm in place of the swiveling HSK T63 head, no rotary table, and a 900 mm (35.4 in) W axis. Both share 2,200 mm (86.6 in) of X, 1,400 mm (55.1 in) of Y and the 2,200x1,200 mm (86.6x47.2 in) table.
04
Pinnacle's standard accessories list for the DU1412 names a Heidenhain TNC640 controller with an HR510 handwheel, kinematic software and DCM anti collision software. Linear scales on 3 axes, A-axis and C-axis rotary encoders and an air conditioner for the electrical cabinet are on the same list.
