Product code: NHC 5000
The NHC Compact Horizontal Machining Center Series (comprising the NHC 4000 and NHC 5000 models) by DN Solutions is a state-of-the-art solution designed to deliver maximum productivity, exceptional accuracy, and highly convenient operational features.
These machines are specifically designed for machining heavy and complex metal parts in the precision engineering industry.

details

The outstanding advantages of the NHC series machines in manufacturing operations:
1. Outstanding Spatial Efficiency
Compact Footprint: The machines are engineered with an optimized, compact design that allows factories to utilize limited floor space with maximum efficiency.
Highly Efficient Replacement: A single NHC horizontal machining center (HMC) can efficiently replace two standard Vertical Machining Centers (VMCs). This structural advantage allows a shop to achieve the same production capacity with 1 machine instead of 2, and requires only 1 operator instead of 2, drastically cutting labor costs and reclaiming valuable shop floor space.

2. Superior Rigidity and Stable Precision
FEM-Optimized Frame: DN Solutions’ engineers utilized Finite Element Method (FEM) analysis to design a highly durable, rigid, and stable machine structure. As a result, the NHC series is fully capable of handling extensive, continuous heavy-duty cutting operations.
High-Speed Roller Guides: The integration of highly rigid and precise Linear Motion (LM) Roller Guides on all axes significantly enhances both machine reliability and overall productivity.
Smart Thermal Compensation: Built-in temperature sensors on the spindle and frame continuously monitor and automatically compensate for thermal displacement during long machining cycles, ensuring consistent accuracy over extended production runs.

3. Exceptional Productivity and Machining Speed
- Powerful High-Torque Spindle:
+ The standard ISO #40 spindle operates at a maximum speed of 8000 r/min, delivering up to 353.4 N·m of torque for robust heavy-duty cutting performance.
+ An optional 15000 r/min direct spindle (spindle power up to 18.5 / 11 kW) is available to maximize material removal rates in high-speed cutting applications.
- Rapid Feed Rates: The axes achieve rapid traverse rates of 48 / 40 / 48 m/min (X / Y / Z axes). Combined with a cutting feedrate of up to 20000 mm/min, non-cutting idle times are minimized to the absolute limit.
- Ultra-Fast Tool Changer (ATC): A highly reliable cam-type Automatic Tool Changer (ATC) minimizes non-cutting times, featuring a tool-to-tool change time of only 1.5 seconds. The standard vertical chain magazine holds 40 tools, with expansion capabilities of 60, 80, 120, 170, or 262 tools.

4. Highly Reliable Automatic Pallet Changer (APC) System
- High-Speed Rotary APC: Swapping pallets is extremely reliable and safe, allowing the operator to easily set up raw parts at the setup station while the machine simultaneously cuts another piece inside the enclosed workspace.
- Fast Pallet Swap Times: Pallet exchange takes only 8 seconds on the NHC 4000 (400 x 400 mm pallet) and 8.5 seconds on the NHC 5000 (500 x 500 mm pallet).
- Substantial Load Capacity: Standard pallets accommodate max loading capacities of 400 kg on the NHC 4000 and 500 kg on the NHC 5000.

5. Ergonomics and Smart "EZ Work" Utilities
- Operator-Centric Interface: The newly designed operating panel features a wide touch screen to improve usability and overall machine ergonomics. Operators can choose between the intuitive DN Solutions Fanuc i Plus and the advanced Siemens SINUMERIK ONE (featuring a conversational 3D UI).
- EZ Work Package: This menu-driven software suite simplifies everyday setup and maintenance tasks, protects the machine, and eliminates operational errors through intelligent features:
+ Adaptive Feed Control (AFC): Automatically adjusts feed rates in real-time based on cutting loads to protect the tool.
+ Spindle Warm-Up: Facilitates automatic thermal stabilization before machining begins.
+ Tool Load Monitor: Monitors tool wear and instantly detects broken cutters.
+ Operation Rate: Provides real-time utilization data and daily history logs.

6. Flexible Integration with Factory Automation
The NHC Series is engineered to support seamless field-retrofitting with DN Solutions' high-level pallet automation systems, maximizing unmanned operating hours:
- DN Round Storage 4000 / 5000 (DRS): A space-saving, slim multi-pallet system (6 pallets standard, expandable to multi-level systems supporting 12, 14, 18, 21, or 24 pallets) that minimizes initial investment and simplifies maintenance.
- Linear Pallet System (LPS 4000 / 5000): A slim, modular system optimized for high-volume, high-mix production. It allows for the easy field-retrofit of up to 7 machines and 12 to 72 pallets, enabling continuous 24/7 unmanned production

Manufacturing Applications
The NHC series is optimized to drive shop-floor productivity through several core manufacturing setups:
- Unmanned, Continuous 24/7 Production: Both the NHC 4000 and NHC 5000 are designed for direct, field-retrofit integration with high-level pallet systems like the DN Round Storage (DRS) or the Linear Pallet System (LPS) . This setup maximizes spindle run-time during unmanned night shifts, mitigates skilled labor shortages, and optimizes overall shop-floor utility.
- High-Mix, Low-Volume (HMLV) Flexibility: Equipped with advanced pallet management and a massive tool storage capacity (expandable from 40 up to 262 tools), these machines allow operators to schedule multiple different parts on a single system without stopping production for manual setups.
- Key Industrial Sectors: The series meets the strict quality and uptime standards of global supply chains:
+ Automotive: Used for high-volume, automated production lines for engine and drivetrain components .
+ Aerospace: Delivers the extreme precision required for structural aircraft parts and engine housings.
+ Medical: Capable of machining complex implants and high-precision surgical instruments.
+ Energy, Semiconductors, Mold & Die, and General Machinery .

Processing Materials
With a highly rigid frame optimized through Finite Element Method (FEM) analysis and a robust ISO #40 spindle, the NHC series easily handles a diverse range of materials:
- Cast Iron and Carbon/Alloy Steel: The standard 8000 r/min spindle delivers a massive torque of 353.4 N·m, enabling stable and continuous heavy-duty cutting on tough cast or forged steels while preserving tool life..
- Aluminum and Light Alloys: Utilizing the optional 12000 r/min or 15000 r/min high-speed direct-drive spindles and a maximum cutting feedrate of 20000 mm/min, the machine achieves exceptional Material Removal Rates (MRR) to dramatically shorten cycle times on lightweight alloy components.
- Superalloys and Titanium: The rigid physical structure dampens vibrations when cutting hard alloys, while smart Thermal Compensation offsets heat-induced dimensional changes, ensuring tight tolerances over long production runs.
