Overview

The DN Solutions DNM 4500 S is the high-speed variant of the DNM 4500, bumping the spindle from 8,000 RPM to 15,000 RPM while keeping everything else that makes the DNM 4500 a proven workhorse. The "S" stands for Speed, and at 15,000 RPM with 18.5 kW (25 hp) and 117.8 Nm of torque through an ISO 40 taper, this spindle covers both high-speed aluminum machining and competent steel cutting. That combination makes the DNM 4500 S one of the most versatile machines in the lineup for shops running a mixed material book of business.

Axis travels of 800 x 450 x 510 mm (31 x 18 x 20 in) match the standard DNM 4500, and the 1,000 x 450 mm table with 600 kg load capacity is identical. Box-way construction carries over, which is an unusual and valuable combination with a 15K spindle — most high-speed VMCs use linear guides to hit those RPM numbers, sacrificing rigidity in the process. The DNM 4500 S gives you the RPM for aluminum without giving up the box-way rigidity for steel.

At 5,000 kg, the machine has enough mass to stay planted during aggressive aluminum roughing at high RPM, and enough rigidity to handle tool-steel finishing at lower speeds. The FANUC 0i-Plus control with iHMI manages the higher spindle speeds seamlessly, with look-ahead functionality that keeps the tool moving smoothly through complex contours at speed. For shops that can't predict whether tomorrow's job will be aluminum or tool steel, the DNM 4500 S eliminates the compromise.

Strengths & Limitations

Strengths

15,000 RPM spindle on a box-way platform is a rare combination — you get high-speed capability without sacrificing rigidity
117.8 Nm torque at 15K RPM means you don't give up steel-cutting capability to gain aluminum speed
Proven DNM 4500 platform with 30,000+ installed DNM series machines worldwide
True mixed-material capability — aluminum, steel, cast iron, and stainless all work well on one machine
Box-way construction provides stability during aggressive roughing that linear-guide high-speed VMCs can't match
FANUC 0i-Plus with look-ahead keeps contouring smooth at high feed rates

Limitations

800 mm X-travel is the standard DNM 4500 envelope — for extended reach, look at the DNM 4500 L or DNM 5700 S
Box-way construction requires periodic maintenance that sealed linear guides don't need
15K RPM is fast but doesn't match the 20K-24K speeds available on dedicated aluminum platforms
Slightly higher price than the standard 8K RPM DNM 4500 for the upgraded spindle

Best For

Job shops running a mixed material book of business that includes both aluminum and steel work Mold shops needing higher spindle speed for electrode machining and finish passes on hardened steel Shops that want high-speed capability without buying a separate dedicated aluminum machine Production environments switching between aluminum and steel batches on the same machine Facilities upgrading from an 8K RPM VMC to gain aluminum speed without losing steel rigidity

Frequently Asked Questions

01 What does a DN Solutions DNM 4500 S cost?

New DNM 4500 S machines run $80,000-$120,000. The base machine with 15K RPM spindle starts around $80,000-$95,000. Adding through-spindle coolant, probing, chip conveyor, and other accessories pushes pricing to $105,000-$120,000. The premium over a standard 8K RPM DNM 4500 is typically $8,000-$12,000.

02 Is 15,000 RPM fast enough for aluminum?

For most job-shop aluminum work, yes. 15K RPM runs a 1/2" endmill at roughly 7,000 SFM, which is well within the high-speed machining range for aluminum. Dedicated aluminum production cells sometimes use 20K-30K RPM machines, but 15K handles the vast majority of aluminum work efficiently. You'll only miss the extra speed on very small tools.

03 What's the difference between the DNM 4500 S and a standard DNM 4500?

The only difference is the spindle: 15,000 RPM versus 8,000 RPM. Everything else — travels, table, box-way construction, control, machine weight — is identical. The S spindle maintains the same 117.8 Nm torque and 25 hp power. The standard model is better value for shops that work primarily in steel; the S pays for itself quickly if you run significant aluminum work.

04 How does the DNM 4500 S compare to the Haas VF-2SS?

Both are mid-size VMCs with high-speed spindles in the 12K-15K RPM range. The DNM 4500 S has box-way construction versus the Haas VF-2SS's linear guides, giving it a rigidity advantage in steel. The Haas offers slightly more Z-travel and inline direct-drive spindle option. For mixed-material shops, the DNM 4500 S's box-way rigidity is the differentiator.
