Campro NU 550

Q: How much does the Campro NU 550 cost?

The price estimate for the Campro NU 550 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/campro-nu-550#price; the request is passed to Campro or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the Campro NU 550 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

Campro builds the NU 550 as a monoblock column 5-axis machining center: a one-piece column and base with a tilting rotary table of Ø550 mm (21.6 in). Travels are 940 mm (37 in) in X, 800 mm (31.4 in) in Y and 550 mm (21.6 in) in Z. The A axis swivels +30°~-120° and the C axis rotates 360°.

This is the model in the series with a real step up in spindle. Campro lists a 12,000 rpm I.D.D spindle with a 20 / 30 kW (40 HP) motor on a BBT-40 shank, where the NU 400C stays at 10,000 rpm and 11 / 15 kW (20 HP). The chain-type tool changer holds 32 tools as standard with 40 or 60 optional. Tool diameter is a little tighter than on the smaller machines: Ø75 mm (Ø2.9 in), or Ø127 mm (Ø5 in) with adjacent pockets empty.

Campro's description leans on the structure. It calls the layout a bridge design that lets large workpieces be machined in a smaller footprint with more rigidity than a standard C-frame, and says the tilting rotary table is supported by a double arm system. The table load is 300 / 250 kg (661 / 551 lb) (V / H) and the stated maximum workpiece is Ø550x350 mm.

Buyers should note that Campro offers both a 4+1 axis version and a 5-axis version. The first gives 4-axis simultaneous motion with positioning on the remaining axis; the second adds simultaneous control of all five. Which one is quoted matters for impeller or blade work.

Installation is on another scale from the C models: 11,000 kg (24,250 lb), a 4,100 × 3,650 mm (161 in x 143 in) floor plan, 3,300 mm (129 in) height and 50 kVA.

Strengths & Limitations

Strengths

12,000 rpm I.D.D spindle with 20 / 30 kW (40 HP), the strongest spindle among the trunnion NU models
940 mm (37 in) of X and 800 mm (31.4 in) of Y travel around a Ø550 mm (21.6 in) tilting rotary table
32-tool chain-type magazine as standard, 40 or 60 optional
One-piece monoblock column and base, with the table supported by a double arm system
Table load of 300 / 250 kg (661 / 551 lb) (V / H)

Limitations

A / C rapid feedrate is 11.1 / 16.6 rpm, no faster than the NU 400C
Maximum tool diameter drops to Ø75 mm (Ø2.9 in), from Ø80 mm (Ø3.1 in) on the NU 400C
Needs 50 kVA and a floor rated for 11,000 kg (24,250 lb)
Offered as a 4+1 axis version as well as a 5-axis version, so full simultaneous control has to be specified
Z travel of 550 mm (21.6 in) is short next to 940 mm (37 in) of X

Best For

Complex parts up to the stated Ø550x350 mm workpiece size Multi-surface machining that benefits from 20 / 30 kW (40 HP) at up to 12,000 rpm Long unattended cycles using the 40 or 60 tool magazine options Tilted plane and thin blade machining on the 5-axis version, as Campro describes it

Frequently Asked Questions

01 What does monoblock column mean on the NU 550?

Campro describes the NU 550 as having a one-piece Monoblock column and base structure, in a bridge design with a tilting rotary table. Its claim is that this allows large workpieces to be machined in a smaller footprint with increased rigidity compared to a standard C-frame design. The machine weighs 11,000 kg (24,250 lb).

02 Is the NU 550 a full simultaneous 5-axis machine?

Campro lists two versions. The 4+1 axis version gives 4-axis simultaneous motion with precise positioning on the remaining axis. The 5-axis version has simultaneous control, which Campro says allows tilted plane machining, cutter thin blade machining and intricate shapes. Confirm which version a quotation covers.

03 What spindle does the NU 550 have?

A 12,000 rpm I.D.D spindle with a 20 / 30 kW (40 HP) motor and a BBT-40 tool shank. Maximum tool diameter is Ø75 mm (Ø2.9 in), or Ø127 mm (Ø5 in) with adjacent pockets empty, maximum length 250 mm (9.8 in) and maximum weight 7 kg (15 lb).

04 How large is the working area of the NU 550?

Travels are 940 mm (37 in) in X, 800 mm (31.4 in) in Y and 550 mm (21.6 in) in Z, with 80~630 mm (3.1 in ~ 24.8 in) from spindle nose to table surface. The table is Ø550 mm (21.6 in) and carries 300 / 250 kg (661 / 551 lb) (V / H). Campro gives the maximum workpiece as Ø550x350 mm.

05 How many tools can the NU 550 carry?

The standard chain-type automatic tool changer holds 32 tools, and Campro lists 40 and 60 tool magazines as options. With a 7 kg (15 lb) tool weight limit and 250 mm (9.8 in) maximum length, the changer is sized for 40-taper cutters, not heavy face mills.
