Overview

The DN Solutions HM 1250 W is the heavy-duty variant of the HM 1250, swapping the standard spindle for a 45 kW (60 hp) powerhouse running at 3,000 RPM with 1,910 Nm of torque. That spindle combined with a 5,000 kg (11,023 lb) pallet capacity makes the W variant the machine you reach for when standard HMCs can't handle the workpiece weight or the material removal demands.

Travel is 2,100 x 1,400 x 1,400 mm (83 x 55 x 55 in), slightly less Y and Z than the standard HM 1250's 1,500 mm — the trade-off for the heavier spindle assembly and increased pallet capacity. The 1,250 x 1,250 mm pallet stays the same, but you've now got 5,000 kg to work with instead of 3,000 kg. That extra 2 tons of capacity matters when you're loading heavy cast iron pump housings, large valve bodies, or mining equipment components.

The 3,000 RPM spindle speed is deliberately low — this machine is built for maximum torque at the cutter, not high-speed finishing. Think large face mills, heavy boring bars, and aggressive roughing in cast iron and steel. The 60-tool magazine keeps cutting sequences flowing, and at 33,000 kg (72,752 lb) machine weight, the HM 1250 W stays planted during the heaviest cuts.

Rapid traverse matches the standard HM 1250 at 24 m/min. The W variant costs more, but shops processing the heaviest workpieces don't have a choice — they need the pallet capacity and spindle torque that the standard model can't provide.

Strengths & Limitations

Strengths

5,000 kg pallet capacity handles the heaviest castings that the standard HM 1250's 3,000 kg can't support
45 kW spindle with 1,910 Nm torque powers through the toughest roughing in cast iron and steel
33,000 kg machine weight provides exceptional stability for heavy interrupted cuts
Same 1,250mm pallet and 60-tool magazine as the standard HM 1250 — fixturing and tooling transfer directly
Purpose-built for maximum metal removal rate in heavy materials
Horizontal orientation with heavy-duty chip conveyor handles the massive chip volume from aggressive cutting

Limitations

3,000 RPM spindle speed severely limits aluminum and high-speed work — this is strictly a heavy-cut machine
1,400 mm Y and Z travel is 100 mm less than the standard HM 1250 per axis
33-ton weight and power consumption increase operating costs versus the standard model
Higher price premium may not be justified unless you consistently load pallets over 3,000 kg

Best For

Mining equipment manufacturers machining heavy cast iron housings and structural components Large pump and compressor manufacturers processing heavy cast iron casings and covers Energy sector shops machining heavy valve bodies and pressure vessel components Heavy equipment OEMs running oversized castings that exceed standard HMC weight limits Steel and iron foundry machine shops with consistently heavy workpieces

Frequently Asked Questions

01 What does a DN Solutions HM 1250 W cost?

New HM 1250 W machines sell for $650,000 to $950,000. The premium over the standard HM 1250 covers the heavier spindle, reinforced pallet system, and increased machine structure needed for the 5,000 kg load rating.

02 Why is the spindle speed only 3,000 RPM?

The W variant prioritizes torque over speed. At 1,910 Nm with 45 kW, the spindle is optimized for large-diameter face mills and boring bars in heavy materials. High RPM would compromise the torque delivery that defines this machine. If you need speed, the standard HM 1250 runs 6,000 RPM.

03 When should I choose the HM 1250 W over the standard HM 1250?

Choose the W when your workpieces consistently exceed 3,000 kg (the standard model's pallet limit) or when you're running large-diameter cutters in heavy materials that demand maximum spindle torque. If your parts weigh under 3,000 kg and you need more spindle speed, the standard model is the better fit.

04 Can the HM 1250 W be automated?

Yes. Like the standard HM 1250, the W variant supports dual-pallet APCs and pallet pool systems. The heavier pallet capacity means automation fixtures and tombstones can also be heavier, expanding fixturing options.
