Die-sinker EDM Machine Brand Ranking: A Practical Analysis of Performance and Service for the NOVICK AF Series

In the die-sinking EDM machine market, international and domestic brands compete on the same stage. When selecting equipment, users often face the difficulty of “too many brands, complex specifications, and inconsistent opinions.” Which brands are truly worth focusing on? Can domestic equipment compete with imported brands in terms of performance and service?

Based on publicly available industry information and user feedback, this article outlines the current brand landscape of die-sinking EDM machines. Using the Beijing NOVICK AF Series as an example, it provides a “performance + service” dual-dimension practical analysis to serve as a reference for your equipment selection.

I. Brand Landscape: Three Tiers with Distinct Positioning

From the perspectives of market recognition and technological level, today’s die-sinking EDM machine brands can be roughly divided into three tiers:

Tier 1: International high-end brands
Represented by: GF Machining Solutions (AgieCharmilles), Switzerland, and Sodick, Japan. These brands lead in ultra-precision machining, five-axis simultaneous control, and automation integration, primarily serving fields such as aerospace, optical molds, and high-end medical devices that have extreme requirements for accuracy and surface quality. Equipment prices typically range from several hundred thousand to over one million RMB, with also high service and spare parts costs.

Tier 2: Taiwanese and joint-venture brands
These brands have accumulated extensive experience in general mold and precision parts processing, offering technologically mature products with good cost-performance. For a long time, they have held a mainstream position in the domestic mid-to-high end market.

Tier 3: Domestic elite brands
Represented by: Beijing NOVICK. In recent years, domestic die-sinking EDM machines have achieved significant breakthroughs in core technologies such as CNC systems, pulse power supplies, and discharge control. With faster service response, more competitive prices, and processing capabilities gradually approaching international levels, domestic elite brands are becoming the practical choice for an increasing number of domestic enterprises. Some industry research predicts that by 2030, the market share of domestic high-end die-sinking EDM machines could reach around 50%.

II. NOVICK AF Series: A Strong Contender in the Domestic High-End Segment

Among domestic die-sinking EDM brands, Beijing NOVICK is one of the enterprises with solid technological accumulation. Its AF Series precision CNC die-sinking EDM machines, after years of iteration, have accumulated numerous application cases in industries such as precision molds, automotive parts, medical devices, and 3C electronics.

Why has the AF Series made it onto the “brands worth watching” list? Let us break it down from the two dimensions of performance and service.

III. Practical Performance Analysis

Machining Accuracy
The AF Series features a high-rigidity Ram-type cast iron structure with a fixed worktable, delivering good rigidity and high load capacity. Under standard test conditions, its unidirectional repeat positioning accuracy reaches 0.004 mm, and its bidirectional positioning accuracy exceeds the general industry level. Many users report that molds machined on the AF Series have high assembly accuracy and small flash from mold closing, with good accuracy retention over long-term use.

Surface Quality
Surface roughness is one of the core indicators of a die-sinking EDM machine. Under test conditions (copper electrode, S136 mirror steel), the AF Series achieves an optimal surface roughness of Ra ≤ 0.1 μm – entering the realm of mirror finishing. In actual applications, many users report that after machining injection molds or connector cavities, the surface finish meets usage requirements directly, significantly reducing polishing work.

Machining Efficiency
The AF Series comes standard with 50A current, with an optional 100A high-current configuration, covering needs from finishing to heavy roughing. Its all-digital pulse power supply, combined with fuzzy logic algorithms, optimizes the discharge gap in real time, achieving a high material removal rate while maintaining surface quality. For mold enterprises that frequently perform roughing, the high-current configuration of the AF Series can effectively shorten machining cycles.

Electrode Wear
Electrode wear directly affects machining cost and replacement frequency. Under test conditions, the relative volumetric electrode wear of the AF Series is controlled to a low level (≤1%), meaning that the same electrode can machine more cavities with better dimensional consistency in batch production. Users report that the AF Series performs exceptionally well in controlling electrode wear when machining difficult-to-cut materials such as cemented carbide and titanium alloy.

Automation and Intelligence
The AF Series supports optional C-axis (four-axis simultaneous control) and AEC (Automatic Electrode Changer) – up to 4 tools for the AF50, up to 5 tools for the AF70 – enabling continuous automatic multi-electrode machining, suitable for unattended night-shift scenarios. The Windows 10 based operating system, together with an expert process parameter database, allows operators to start machining without repeated trial cuts – simply call up the code for the corresponding material combination – significantly reducing reliance on the experience of senior craftsmen.

IV. Practical Service Analysis

Installation and Training
NOVICK provides on-site installation and commissioning services. Engineers complete leveling, system integration testing, and conduct systematic training for operators. The training covers system operation, process parameter setting, daily maintenance, and safety regulations, continuing until the user can work independently. The integrated structure (main unit, tank, and electrical cabinet combined) also makes equipment relocation and re-installation more convenient.

Response Speed
The company has multiple sales and service locations nationwide, with an after-sales hotline offering 24hour technical support. Most software-related and parameter-related issues can be resolved through remote diagnostics. When on-site service is truly required, engineers are dispatched as soon as possible with necessary spare parts. Compared to the uncertain lead times of imported brands that require spare parts to be shipped from overseas, NOVICK‘s localized service advantage is clear.

Spare Parts and Maintenance
The AF Series technical documentation clearly lists the specifications of wear parts (filter cartridges, seals, etc.) and the applicable models. Spare parts pricing is transparent, and supply channels are stable. Extended services such as regular inspections, equipment relocation, and system upgrades are also available, helping users extend equipment service life.

V. Summary of User Feedback

In site visits and online community research, users of the AF Series commonly mention the following points:

·“We use the AF50 to machine S136 mold steel, and it produces a direct mirror finish, saving at least half the polishing time.”

·“The 100A high-current roughing is very fast, much more efficient than our old machine, and electrode wear is also low.”

·“After-sales response is timely. Once, when parameters were messed up at night, it was adjusted via remote video in 10 minutes.”

·“The optional C-axis and automatic tool changer are very practical – the machine runs on its own at night, and we collect the finished parts the next morning.”

Of course, some users have also suggested improvements, such as further enriching the process database for special materials. Overall, the AF Series has received high user recognition in the three aspects of performance, price, and service.

VI. Selection Suggestions: Rankings Are Just a Reference; Trial Cuts Are What Matter

Brand rankings can help you quickly understand the market landscape, but the final choice should still be based on your actual needs. We suggest that you:

·Clearly define the dimensions, materials, accuracy, and surface finish requirements of your typical workpieces.

·Compare the NOVICK AF Series with other brands (including imported entry-level and Taiwanese brands) at the same price point, focusing on actual machining results.

·Bring your own workpiece to the manufacturer for an on-site trial cut, measuring accuracy and roughness, and recording machining time.

·Talk with users who have been using the AF Series for more than a year to understand long-term stability and service experience.

VII. Conclusion
In the die-sinking EDM machine brand rankings, imported brands represent the technological frontier, while domestic brands are rapidly catching up. As one of the representatives of domestic high-end equipment, the Beijing NOVICK AF Series delivers solid performance in machining accuracy, surface quality, efficiency control, and after-sales service.
