Overview

The DN Solutions DNM 4500 S is the 15,000 rpm member of the DNM 4500 family of vertical machining centers. Travels are 800 × 450 × 510 mm (31 × 18 × 20 in) and the table measures 1,000 × 450 mm (39 × 18 in). The DNM 4500 4TH, its nearest relative, tops out at 8,000 rpm.

On paper the extra speed costs nothing in rating. DN lists 18.5 kW (25 hp) and 117.8 N·m (87 ft-lb) for the DNM 4500 S, the same power and torque figures the DNM 4500 4TH shows. What 15,000 rpm buys is surface speed for small cutters. A small end mill or ball mill in aluminium, or a fine finishing pass on a contoured surface, runs at a proper cutting speed instead of being held back by the spindle. The table does not say at which speed the torque figure applies, so anyone planning heavy roughing at low rpm should ask for the spindle's power and torque diagram.

The table is longer than the stroke: 1,000 mm of table over 800 mm of X travel. The ends cannot be machined. They are useful for clamps, a tool setter or a part waiting for its second operation, but the working length stays at the X travel. Y travel equals the 450 mm table depth, and the load limit is 600 kg (1,323 lb).

Rapids are 42 m/min (1,654 ipm) on X and Y and 36 m/min (1,417 ipm) on Z. The spindle is direct-coupled, which DN contrasts with belt-driven types, and grease lubrication for the axis roller guideways is standard. DN's table lists no spindle taper for this model. The machine measures 2,158 × 2,615 × 2,985 mm (85 × 103 × 118 in) and weighs 5,000 kg (11,023 lb).

Strengths & Limitations

Strengths

15,000 rpm direct-coupled spindle, against 8,000 rpm on the DNM 4500 4TH
Power and torque are listed at 18.5 kW (25 hp) and 117.8 N·m (87 ft-lb), unchanged from the slower-spindle DNM 4500 4TH
1,000 × 450 mm (39 × 18 in) table leaves clamp and setter space beyond the cutting area
42 m/min (1,654 ipm) rapids on X and Y with 36 m/min (1,417 ipm) on Z
Grease lubrication for the axis roller guideways is supplied as standard

Limitations

X travel is 800 mm (31 in) under a 1,000 mm (39 in) table, so the table ends cannot be machined
DN's table lists no spindle taper for this model
Table load is 600 kg (1,323 lb); the DNM 5700 S carries 800 kg (1,764 lb) with the same 15,000 rpm
No speed is given for the 117.8 N·m (87 ft-lb) torque figure, so low-rpm roughing capability has to be checked

Best For

Aluminium parts machined with small end mills at up to 15,000 rpm Fine-step finishing of contoured surfaces, where spindle speed sets the feed Mixed work that calls for both 15,000 rpm and 18.5 kW (25 hp) Parts within 800 × 450 × 510 mm (31 × 18 × 20 in) and 600 kg (1,323 lb)

Frequently Asked Questions

01 How fast is the DNM 4500 S spindle?

Maximum speed is 15,000 rpm, with 18.5 kW (25 hp) and 117.8 N·m (87 ft-lb) listed. The DNM 4500 4TH has the same power and torque figures at a maximum of 8,000 rpm, so the DNM 4500 S is the one to pick when small tools and light alloys make up most of the work.

02 Why is the table longer than the X travel?

The table is 1,000 × 450 mm (39 × 18 in) and X travel is 800 mm (31 in). The spindle therefore covers only part of the table length. The remainder holds clamps, stops or a tool setter. Size fixtures to the travel, not to the table.

03 Should I choose the DNM 4500 S or the DNM 5700 S?

Both run to 15,000 rpm. The DNM 5700 S is the larger machine, with 1,050 × 570 × 510 mm (41 × 22 × 20 in) travels, a 1,300 × 570 mm (51 × 22 in) table, an 800 kg (1,764 lb) load and a weight of 6,500 kg (14,330 lb). The DNM 4500 S has 450 mm (18 in) of Y, carries 600 kg (1,323 lb) and weighs 5,000 kg (11,023 lb).

04 Which spindle taper does the DNM 4500 S use?

DN's table for this model has no taper row. The DNM 4500 4TH and the DNM 4500 L both list ISO 40, but that is their table, not this one. Confirm the taper and the tool magazine size on the quotation before ordering holders.

05 What are the dimensions and weight of the DNM 4500 S?

DN lists 2,158 × 2,615 × 2,985 mm (85 × 103 × 118 in) as length, width and height. Machine weight is 5,000 kg (11,023 lb), the same as the DNM 4500 4TH.
