Our best estimate for a horizontal machining centers (hmc) in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

The DN Solutions NHP 4000 is a compact 40-taper horizontal machining center: a 400 mm (16 in) pallet, a 15,000 rpm spindle and 60 m/min (2,362 ipm) rapids in a machine that weighs 9,700 kg (21,385 lb). Among the NHP models DN Solutions compares it is the smallest, one step below the NHP 5000.

The envelope is taller and deeper than it is wide. X travel is 560 mm (22 in), Y is 640 mm (25 in) and Z is 660 mm (26 in). With a 400 mm pallet and 400 kg (882 lb) of table load, that describes tombstone work on small and medium parts: valve bodies, housings, manifolds and brackets loaded several to a face, not single large castings. The NHP 5000 is the next size if a part or fixture runs out of room, with 730 mm (29 in) of X and Y, 880 mm (35 in) of Z and a 500 kg (1,102 lb) load.

The spindle is listed at 30/18.5 kW (40/25 hp) and 230 N·m (170 ft-lb), with an option at 37/22 kW (50/30 hp) and 303 N·m (224 ft-lb). Top speed is 15,000 rpm and the table shows no faster option for this model, where the NHP 5000 lists 20,000 rpm as an option. That speed and torque suit aluminium and small to mid-size tooling in steel. Heavier roughing belongs to the larger models: the NHP 5500 2ND has an ISO 50 spindle listed at 516 N·m (381 ft-lb).

DN Solutions states that the NHP series uses roller-type LM guideways on all axes, a step-guide bed under the column and a double-wall main body intended to stop coolant leaks. The tool changer and pallet changer are servo-driven, and tool capacity is 40. For running more pallets than the changer holds, DN lists a Linear Pallet System (LPS) and a Multi-Pallet System (MPS) as pallet extension systems for the series.

The footprint is 4,950 × 2,300 mm (195 × 91 in) and the height 2,690 mm (106 in). The 2,300 mm width matters when several machines stand side by side along a pallet line.

Strengths & Limitations

Strengths

15,000 rpm ISO 40 spindle with 60 m/min (2,362 ipm) rapids for short cycle times on small parts
Optional spindle rating of 37/22 kW (50/30 hp) and 303 N·m (224 ft-lb) over the standard 30/18.5 kW (40/25 hp) and 230 N·m (170 ft-lb)
Y travel of 640 mm (25 in) and Z of 660 mm (26 in) exceed the 560 mm (22 in) of X, which gives room for tall tombstones and long tools
Footprint of 4,950 × 2,300 mm (195 × 91 in) and a weight of 9,700 kg (21,385 lb), the lightest of the NHP models compared
Roller-type LM guideways on all axes and servo-driven tool and pallet changers are listed for the series

Limitations

Table load is 400 kg (882 lb), which a tombstone and hydraulic fixtures can use up before the parts are added
X travel is 560 mm (22 in); the NHP 5000 offers 730 mm (29 in)
No spindle faster than 15,000 rpm appears in the table for this model, while the NHP 5000 lists a 20,000 rpm option
ISO 40 taper and 230 N·m (170 ft-lb) standard torque limit large-diameter cutters and heavy boring

Best For

Small aluminium housings and manifolds on a 400 mm (16 in) pallet High-volume parts where 60 m/min (2,362 ipm) rapids shorten the cycle Multi-face tombstone fixtures within the 400 kg (882 lb) load limit Pallet-pool cells built with the listed LPS or MPS extensions Shops with limited floor width for a horizontal

Frequently Asked Questions

01 What size parts suit the NHP 4000?

The pallet is 400 mm (16 in) and the travels are 560 mm (22 in) in X, 640 mm (25 in) in Y and 660 mm (26 in) in Z, with a 400 kg (882 lb) table load. That favours small and medium prismatic parts mounted on a tombstone. The table does not give a maximum workpiece swing or height, so check the machine drawing for the largest fixture that clears the enclosure.

02 What spindle does the NHP 4000 have?

An ISO 40 spindle with a top speed of 15,000 rpm. The standard rating is 30/18.5 kW (40/25 hp) with 230 N·m (170 ft-lb) of torque, and the option is 37/22 kW (50/30 hp) with 303 N·m (224 ft-lb). DN Solutions prints the power as a pair of ratings and the table does not say what duty each one refers to.

03 How is the NHP 4000 different from the NHP 5000?

Size and one spindle option. The NHP 4000 has a 400 mm (16 in) pallet, 560 × 640 × 660 mm travels, a 400 kg (882 lb) load and weighs 9,700 kg (21,385 lb). The NHP 5000 has a 500 × 500 mm (20 × 20 in) pallet, 730 × 730 × 880 mm travels, a 500 kg (1,102 lb) load and weighs 11,500 kg (25,353 lb). Standard spindle ratings and the 60 m/min (2,362 ipm) rapids are the same, but only the NHP 5000 lists a 20,000 rpm option.

04 Can the NHP 4000 run with more pallets?

DN Solutions lists two pallet extension systems for the NHP series: the Linear Pallet System (LPS) and the Multi-Pallet System (MPS). The table for the NHP 4000 does not state how many pallets either system adds, so the pallet count and the floor space of the extension need to be confirmed for the layout in question.

05 How much room does the NHP 4000 take up?

The listed dimensions are 4,950 × 2,300 × 2,690 mm (195 × 91 × 106 in) as length, width and height, and the machine weighs 9,700 kg (21,385 lb). Allow extra space at the pallet-loading end and for chip removal and service access.
