Used Mazak HCN-4000II Horizontal Machining CenterThe Mazak HCN-4000II is a high-speed horizontal machining center (HMC) engineered for high-volume production environments. This unit features a 400x400mm pallet, an 18,000 RPM BT40 spindle, and a 560x630x640mm work envelope. Equipped with a full 0.001-degree indexing table, this machine is built for precision multi-sided machining. It is currently in stock and available for immediate inspection, offering an instant capacity boost for facilities requiring high-speed milling, drilling, and tapping across diverse industrial sectors.

Key Specifications & Production Suitability

Understanding the core specifications of the HCN-4000II is essential to determining how it integrates into your existing workflow. This machine is configured for speed and agility rather than heavy-duty roughing on large steel castings.

  • 18,000 RPM BT40 Spindle: This high-speed configuration is optimized for aluminum, light alloys, and finishing operations where surface finish and cycle time are critical. It is not intended for heavy-duty steel hogging.
  • 0.001-Degree Table Indexing: This allows for precise angular positioning, which is essential for multi-face machining in a single setup, such as complex housings or manifolds.
  • 40-Tool ATC: The 40-tool capacity provides a sufficient buffer for complex parts or high-mix production, minimizing the need for frequent tool changes or operator intervention.

Workpiece Capacity & Application Fit

The HCN-4000II is best suited for small-to-medium sized components. The 400mm pallet is the primary limiting factor for your workpiece footprint. If your parts fit within a 400mm cube (accounting for fixture height), this machine provides the necessary rigidity and speed.

The BT40 spindle taper is the industry standard for high-speed machining, balancing tool rigidity with rapid tool change times. This setup is highly effective for:

  • Automotive: Engine components, transmission housings, and lightweight structural parts.
  • Aerospace: Small-to-medium aluminum brackets, valve bodies, and structural fittings.
  • Medical Devices: Precision surgical instrument components or housings requiring superior surface finishes.
  • Electronics: Heat sinks and chassis components where high-speed milling is required for efficiency.

Evaluating the HCN-4000II for Your Shop

When evaluating this machine for your floor, consider the synergy between the Mazatrol Matrix Nexus control and the high-speed spindle. The Matrix Nexus control is widely recognized for its intuitive, conversational interface, which can significantly reduce setup times for operators familiar with the Mazatrol environment.

The inclusion of through-spindle coolant (TSC) and the Daikin oil chiller are critical for production stability. The oil chiller manages spindle thermal growth, ensuring dimensional consistency during long production runs. The TSC is essential for deep-hole drilling and clearing chips from complex internal cavities, a common requirement in mold making and precision housing production.

Is the HCN-4000II Right for Your Workflow?

This machine is an ideal candidate for your production line if:

  • You are running high-volume production of aluminum or light-alloy parts.
  • Your current workflow requires high-speed finishing and complex multi-face indexing.
  • You have existing Mazatrol programming capabilities in your shop.
  • Your part sizes consistently fall within the 400mm envelope.

If your primary workload involves heavy-duty, large-scale steel milling (e.g., heavy iron castings), the BT40 spindle and 400mm pallet size may be undersized for your requirements. This machine is built for throughput and precision, not heavy-duty material removal.

Frequently Asked Questions

Q: Can this machine handle heavy steel roughing?

A: The HCN-4000II with an 18,000 RPM BT40 spindle is optimized for high-speed finishing and light-to-medium milling. While it can cut steel, it is not designed for the heavy-duty material removal typically associated with larger BT50 machines.

Q: What is the maximum part size this machine can accommodate?

A: The table is 400x400mm. While the travels are 560x630x640mm, your fixture and part must be designed to fit within the pallet area while allowing for clearance during tool changes and rotation.

Q: Is the Mazatrol Matrix Nexus control difficult to learn?

A: The Matrix Nexus is known for its conversational programming, which is generally considered user-friendly for operators. It allows for quick program creation directly at the machine, which is highly beneficial for high-mix production.

Q: Is this machine ready for immediate production?

A: This unit is currently in stock. We encourage prospective buyers to schedule an inspection to verify the spindle, table, and control functionality before shipment.
