Overview

The Mazak HCN-4000 is the original-generation compact 400mm horizontal machining center that established Mazak's presence in the small-pallet HMC market. Preceding the HCN-4000 III and HCN-4000 NEO, this model was produced across multiple generations and remains widely available on the used market, making it one of the most common entry points for shops adding horizontal machining capability.

The HCN-4000 is built around 400 x 400 mm (15.7 x 15.7 in) pallets with axis travels of 560 x 510 x 510 mm (22 x 20.1 x 20.1 in). The standard twin-pallet APC provides the production advantage that defines horizontal machining: one pallet cuts while the operator loads the next. Maximum workpiece size reaches 500 mm (19.7 in) diameter by 800 mm (31.5 in) height.

Spindle configurations varied across production years, with CAT 40, BT 40, and HSK-A63 versions available. Typical specifications include a 12,000 RPM spindle with 18.5 kW (25 hp), though higher-speed and higher-power variants were produced. The B-axis provides 1-degree indexed pallet positioning for four-face access.

The control evolved from MAZATROL Fusion 640M to Matrix to Matrix NEXUS across production generations. Tool magazine capacity ranges from 40 to 120 tools depending on configuration. Rapid traverse reaches 50-60 m/min depending on generation.

Used HCN-4000 machines from 2000-2015 trade between $40,000 and $150,000, making them excellent value propositions for shops entering horizontal machining. Competitors across generations include the Okuma MB-4000H, Makino a40, and Mori Seiki NH4000.

Strengths & Limitations

Strengths

Excellent used market value makes horizontal machining accessible to shops that cannot justify $500,000+ for a new HMC
Twin-pallet APC provides production automation advantages that dramatically outperform VMCs on repetitive work
Proven platform with thousands of units installed worldwide ensures parts availability, service knowledge, and training resources
Multiple spindle taper options across generations allow shops to match their existing tooling inventory
Compact 400mm pallet footprint fits into shop layouts that cannot accommodate larger HMCs
PALLETECH integration available on most generations for scaling into multi-pallet automation

Limitations

Older control generations (Fusion 640M, Matrix) lack the AI-based optimization and IoT connectivity of current SmoothAi
300 kg table load on earlier generations limits fixture complexity compared to 400 kg on the HCN-4000 III/NEO
12,000 RPM spindle speed on standard variants is lower than the 15,000 RPM on current generation machines
Used machines may have accumulated wear requiring spindle rebuilds, ballscrew replacement, or other significant maintenance

Best For

Shops entering horizontal machining for the first time seeking a proven, affordable platform to build experience Job shops needing twin-pallet production capability at a fraction of new machine cost Training facilities and technical schools requiring reliable HMC platforms for CNC education programs Small-to-medium manufacturers running repetitive prismatic parts where used equipment provides acceptable precision Shops building budget FMS cells with multiple used HCN-4000 units connected to PALLETECH automation

Frequently Asked Questions

01 What does a used Mazak HCN-4000 cost?

Used HCN-4000 machines from 2000-2015 sell for $40,000 to $150,000 depending on age, condition, control generation, and installed options. Units with Matrix NEXUS controls and higher-hour machines with recent spindle rebuilds tend to command premiums in this range.

02 What should I look for when buying a used HCN-4000?

Key inspection points include spindle hours and runout, ballscrew condition (check backlash and ballbar results), pallet changer reliability, ATC function, and control generation. Request recent maintenance records and ask about spindle rebuilds. A pre-purchase inspection by a Mazak-certified technician is worth the investment.

03 Which control generation is best?

Matrix NEXUS is the most recent and feature-rich control on used HCN-4000 units. The original Matrix is solid and well-supported. Fusion 640M is oldest and least capable but still functional for production work. Avoid machines with controls that Mazak no longer supports with parts and service.

04 How does the HCN-4000 compare to the HCN-4000 III?

The HCN-4000 III upgraded to SmoothG/SmoothAi CNC, increased workpiece weight to 400 kg, added 15,000 RPM spindle capability, and improved thermal management. The original HCN-4000 is mechanically similar but lacks the latest control intelligence and has lower specs in some areas.
