How Good Is the NOVICK AW600 Brass Wire Cut EDM Machine? A Real-World Evaluation Across Five Dimensions

Among domestic Brass Wire Cut EDM brands, Beijing NOVICK has been gaining increasing market attention in recent years. Its AW series high-end model, the AW600, is designed for large precision molds and complex part machining, delivering solid performance in terms of accuracy, stability, and automation. This article provides an objective evaluation across five dimensions – structure, accuracy, discharge control, automatic wire threading, software and service – based on public specifications and user feedback, as a reference for purchasing professionals.

I. What Size of Workpiece Can It Handle? – Moving-Column Structure with 800 kg Load Capacity

The AW600 adopts a moving-column structure (X‑axis in front, Y‑axis at the rear), where the workpiece stays fixed and the column moves. This design offers better rigidity and more stable movement when machining heavy workpieces. The worktable travel is 600×400×360 mm, the maximum workpiece weight is 800 kg, and the effective work tank size is 1100×850×420 mm.

Evaluation Conclusion: For enterprises that need to machine large molds or clamp multiple workpieces in a single setup, the AW600's specifications are clearly superior to the common 400×300 mm class machines, reducing repeated clamping errors and improving efficiency.

II. What Level of Accuracy Does It Deliver? – Positioning 0.005 mm, Repeatability 0.003 mm

Equipped with precision linear rolling guides and C3‑class precision ball screws, plus five‑axis AC servo control with a minimum resolution of 1 μm, measured data shows X/Y/U/V‑axis bidirectional positioning accuracy of 0.005 mm and repeat positioning accuracy of 0.003 mm. Taking a regular octagon cut in 20 mm thick Cr12 material as an example, dimensional accuracy is consistently controlled within ≤6 μm, and optimal surface roughness reaches Ra ≤0.45 μm, or Ra ≤0.25 μm with the addition of a finishing module.

Evaluation Conclusion: This level of accuracy is fully capable of meeting the vast majority of high‑precision machining requirements for precision connector molds, stamping dies, medical parts, and more. Although it does not reach the extreme ±0.001 mm level of some imported machines, it is more than sufficient for over 95% of enterprise applications – at a significantly lower price point.

III. Is the Discharge Stable? – AC Electrolysis-Free Technology, Monitoring Every Pulse in Real Time

The AW600 features an industrial computer plus a multi‑MCU distributed control system, combined with a high‑efficiency MOSFET discharge circuit, achieving full‑process AC electrolysis-free machining from roughing to finishing. This technology significantly reduces electrolytic corrosion and micro‑cracks on the workpiece surface, extending mold life. The system monitors the status of each discharge pulse in real time and dynamically adjusts pulse energy, reducing the probability of wire breakage when machining thick workpieces and complex geometries.

Evaluation Conclusion: Discharge control is one of the core technologies of Brass Wire Cut EDM. The AW600's AC electrolysis-free technology and real‑time pulse monitoring demonstrate the manufacturer's R&D depth and are key guarantees of its machining stability.

IV. Is the Automatic Wire Threading User-Friendly? – AWF System, Self-Resumes After a Break

The AW600 is equipped with the AWF automatic wire threading system, supporting automatic wire burning, automatic wire threading, automatic wire breakage detection, and automatic return to the breakpoint for re-threading (up to 9 bending and retraction actions). It also supports automatic air pressure detection, automatic waste wire recovery, and automatic waste wire disposal.

Evaluation Conclusion: Many domestic machines offer automatic wire threading that works under simple conditions, but cannot automatically return to the breakpoint after a wire break. The AW600's breakpoint return function is the real key to true "unattended" operation, making it suitable for enterprises that need night-shift continuous processing or batch production.

V. Is the Software Difficult to Learn? – Windows-Based Interface, Feature-Rich and Easy to Learn

Based on a Windows 10 industrial control platform, it supports ISO code programming, 3D trajectory graphic inspection, real-time machining path tracking, automatic overcut correction, corner adaptive processing, small-arc adaptive machining, and taper error compensation. Machining parameters and offset values can be modified in real time during processing, with support for graphical programming and CAD-assisted processing.

Evaluation Conclusion: The software interface is similar to that of an ordinary computer, resulting in a low learning curve. The rich set of adaptive compensation functions is highly beneficial for complex part programming and for ensuring machining quality.

VI. How Are the Wire Drive and Water Handled? – Two-Stage Constant Tension, 5 μm Precision Filtration

The machine adopts a two-stage constant tension wire drive mechanism, with sensors adjusting the wire feed motor speed in real time to maintain stable wire tension. The tank system features a high-pressure pump, circulation pump, filtration pump, and constant-temperature cooling device, with a filtration accuracy of 5 μm for the dielectric fluid and automatic water conductivity control. High-pressure jetting supports roughing with 1.2 MPa high-pressure flushing, switching to low-flow stable flushing for finishing.

Evaluation Conclusion: The details of wire drive and water treatment directly affect long-term machining stability and consumable costs. The AW600's configuration in these two areas reaches the standard level of domestic high-end models.

VII. Is After-Sales Support Reliable? – Full Service: Installation, Training, Maintenance, Relocation, Upgrades

Installation and Commissioning: On-site engineers complete equipment placement, leveling, electrical connection, and system integration testing, supported by remote assistance.

Application Training: Three-part training covering system operation, equipment operation, and maintenance, with on-site assessment.

Routine Maintenance: Regular on-site lubrication, calibration, and system checks, with a maintenance report provided.

Equipment Relocation: Professional non-damage disassembly, transportation, reinstallation, and accuracy restoration.

Function Upgrades: Operating system upgrades and process library updates, benefiting existing users.

Evaluation Conclusion: After-sales service is a major advantage of domestic equipment compared to imported brands. NOVICK provides full lifecycle service from installation to upgrades, with fast response times and ample spare parts availability.

What Are Users Saying? (Selected Anonymous Feedback)

"We manufacture automotive stamping dies, often with workpieces weighing 400–500 kg. Previously, we used imported machines – high price, slow after-sales. After switching to the AW600, the cutting accuracy fully meets our requirements, the automatic wire threading is very reliable, and we don't need anyone on night shift." – Technical Supervisor, a Mold Factory in Zhejiang

"The software is quick to pick up. Our operators, who were used to Fanuc systems, got comfortable with it in two days. Being able to modify parameters in real time without stopping the machine is very convenient." – Operator, a Precision Parts Processing Enterprise in Suzhou

"Last year, when our factory relocated, the manufacturer sent people to disassemble, move, and recalibrate the machine, and also upgraded our system at no extra charge. This kind of service is hard to get from imported brands." – Owner, a Machining Shop in Dongguan

Overall Conclusion

The NOVICK AW600 is a high-end domestic Brass Wire Cut EDM model that delivers solid performance, balanced specifications, and comprehensive service. It does not attempt to challenge the extreme precision of top imported brands, but within the accuracy range that the vast majority of enterprises actually need, it provides stable and reliable machining capability at a highly competitive price. If you are looking for a large-scale Brass Wire Cut EDM machine that can substitute for imports, control costs, and offer hassle-free after-sales support, the AW600 is well worth putting on your shortlist.
