Overview
The DN Solutions HC 400 II is a compact horizontal machining center designed for shops that need the productivity advantages of horizontal machining—gravity-assisted chip evacuation, multi-face access, and pallet automation—in a smaller, more affordable package than 500mm-class HMCs. With 600 x 560 x 565 mm (24 x 22 x 22 in) of travel and a 400 x 400 mm (16 x 16 in) pallet supporting 400 kg (882 lb), the HC 400 II is sized for automotive brackets, valve bodies, hydraulic manifolds, and other small-to-medium components.
The 8,000 RPM spindle with optional 12,000 RPM upgrade delivers 18.5 kW (25 hp) and 353.4 Nm (261 ft-lb) of torque through an ISO 40 taper—well-matched for the machine's target applications in steel, cast iron, and aluminum. The 40-tool magazine keeps tool-change overhead low, and rapid traverse of 40 m/min (1,575 ipm) on all axes provides responsive positioning. The dual-pallet changer enables loading one pallet while the machine cuts on the other, keeping spindle utilization high even in lower-volume production.
At 11,000 kg (24,251 lb), the HC 400 II is built with the same casting philosophy as DN Solutions' larger HMCs—heavily ribbed, thermally designed structures that maintain accuracy across long production runs. The compact 4,630 x 2,260 x 2,830 mm (182 x 89 x 111 in) footprint makes it one of the most floor-space-efficient HMCs available. The FANUC 0i-Plus control provides familiar, reliable operation. The HC 400 II competes with the Mazak HC-4000, Okuma MB-4000HII, and Haas EC-400 in the compact HMC segment.

Strengths & Limitations
Strengths
- Compact footprint (4,630 x 2,260 mm) makes it one of the most floor-space-efficient HMCs on the market
- 353.4 Nm spindle torque through ISO 40 provides aggressive roughing capability uncommon in compact HMCs
- Dual-pallet changer comes standard, enabling high spindle utilization even in job shop environments
- 11,000 kg machine weight provides rigidity that exceeds lighter competitors in the 400mm HMC class
- Lower entry cost than 500mm HMCs while still delivering the core productivity benefits of horizontal machining
Limitations
- 400 kg pallet load capacity limits fixture and workpiece size for heavier steel applications
- 8,000 RPM standard spindle speed is on the lower end for aluminum-heavy applications
- 600 mm X-travel and 560 mm Y-travel constrain part size compared to 500mm-class HMCs
- 40 m/min rapid traverse is slower than high-performance HMCs, adding cycle time in multi-tool jobs

Frequently Asked Questions
01
A new DN Solutions HC 400 II typically runs between $200,000 and $320,000 depending on configuration. The base machine with 8,000 RPM spindle, 40-tool ATC, and dual-pallet changer starts around $200,000-$240,000. Adding the 12,000 RPM spindle, through-spindle coolant, probing, and expanded tool magazine pushes pricing to $260,000-$290,000. A fully loaded machine with 90-tool ATC and automation options reaches $290,000-$320,000.
02
Both are compact 400mm-pallet HMCs. The HC 400 II delivers significantly more torque (353 vs 122 Nm), heavier construction (11,000 vs ~7,700 kg), and typically better long-term accuracy. The Haas EC-400 costs roughly $40,000-$60,000 less and benefits from Haas's extensive service network. For shops prioritizing cutting performance and rigidity, the HC 400 II is the better machine. For shops prioritizing initial cost and service accessibility, the Haas is competitive.
03
Yes. The HC 400 II is an excellent first HMC for several reasons: compact footprint fits in most shops without major rearrangement, the dual-pallet changer immediately boosts spindle utilization versus a VMC, 400mm pallets and 400 kg load capacity handle most job-shop-sized work, and the FANUC control is familiar to most operators. The lower investment versus 500mm HMCs reduces the financial risk of transitioning from vertical to horizontal machining.
