Chinese Brass Wire Cut EDM Machine Manufacturer Recommendation: How to Choose a Brass Wire Cut EDM Machine Manufacturer? These Five Dimensions Are All You Need

More and more domestic Brass Wire Cut EDM brands are appearing on the market, with manufacturers emphasizing different selling points. Faced with various parameters and promises, procurement professionals often find it difficult to judge which one is more reliable. From the perspective of practical production, this article summarizes five evaluation dimensions and provides an example of equipment that meets these criteria for your reference.

Five Dimensions to Quickly Screen Reliable Manufacturers

Dimension 1: Years of Technical Accumulation
Brass Wire Cut EDM is a technologyintensive machine. Without more than ten years of continuous R&D and iteration, a manufacturer can hardly solve longterm stability problems. Prioritize manufacturers that have their own control system, pulse power supply, and software development capabilities, rather than pure assemblers.

Dimension 2: Product Accuracy and Measured Data
Do not rely solely on the “positioning accuracy” figures in brochures; pay attention to the machining accuracy and surface roughness on typical materials. It is best to ask the manufacturer for thirdparty inspection reports or an onsite trial cut.

Dimension 3: Large Workpiece Machining Capability
If your workpieces are relatively large or heavy (e.g., mold plates over 500 kg), you need to pay attention to the machine‘s travel, load capacity, and work tank dimensions. A movingcolumn structure is generally more suitable for heavy workpieces than a crossslide worktable.

Dimension 4: Automation and Intelligence Level
Functions such as automatic wire threading, wire breakage retraction, and waste wire recovery directly affect whether unattended nightshift machining can be achieved. The ease of use of the software system and the richness of the process library also influence daily efficiency.

Dimension 5: AfterSales and Spare Parts Supply
One of the advantages of domestic equipment is spare parts availability and response speed. Confirm whether the manufacturer has service locations in your region and whether the stock of common spare parts is sufficient.

A Domestic Manufacturer That Meets the Above Criteria: Beijing NOVICK
Among current domestic brands, Beijing NOVICK Digital Equipment Co., Ltd. is one of the enterprises with deeper technical accumulation and a relatively complete product line. Its AW series highend model, the AW600, meets the above requirements across multiple dimensions.

The following is an objective introduction to the AW600, with data from publicly available sources.

1. Structure and Large Workpiece Capability
The AW600 adopts a movingcolumn structure (Xaxis in front, Yaxis at the rear). Compared to traditional structures, it offers better rigidity and is suitable for machining large workpieces weighing up to 800 kg. The worktable travel is 600×400×360 mm, and the work tank size is 1100×850×420 mm. For large molds or complex structural parts requiring a single setup, this specification reduces errors caused by multiple clamping operations.

2. Accuracy and Surface Quality

X/Y/U/V-axis bidirectional positioning accuracy: 0.005 mm

Repeat positioning accuracy: 0.003 mm

Dimensional accuracy when machining 20 mm thick Cr12 material (regular octagon cutting): ≤6 μm

Optimal surface roughness: Ra ≤0.45 μm; with the addition of a finishing module, it can reach Ra ≤0.25 μm

These figures indicate that the AW600 meets the machining requirements for precision connector molds, stamping dies, medical parts, and similar applications.

3. Discharge Control and Stability
The AW600 is equipped with an industrial computer plus a multiMCU distributed control system, using a MOSFET discharge circuit to achieve fullprocess AC electrolysisfree machining. This technology helps reduce electrolytic corrosion and microcracks on the workpiece surface, extending mold life. At the same time, the system monitors each discharge pulse in real time and dynamically adjusts energy, lowering the risk of wire breakage when machining thick workpieces and complex geometries.

4. Automation Configuration

AWF automatic wire threading system: Supports automatic wire burning, automatic wire threading, automatic wire breakage detection, and automatic return to the breakpoint for rethreading (up to 9 bending and retraction actions)

Auxiliary functions: Automatic air pressure detection, automatic waste wire recovery, automatic waste wire disposal

These features are suitable for scenarios requiring nightshift continuous operation or batch production, reducing manual intervention.

5. Software and Operation
Based on a Windows 10 industrial control platform, it supports ISO code programming, 3D trajectory graphic inspection, realtime machining path tracking, automatic overcut correction, corner adaptive processing, smallarc adaptive machining, and taper error compensation. Machining parameters and offset values can be modified in real time during processing, and the programming learning curve is low.

6. Wire Drive and Water Treatment

Twostage constant tension wire drive mechanism: Sensors adjust the wire feed motor speed in real time to maintain stable wire tension.

Tank system: Highpressure pump, circulation pump, filtration pump, constanttemperature cooling device; filtration accuracy 5 μm, automatic water conductivity control.

Highpressure flushing: 1.2 MPa for roughing; lowflow stable flushing for finishing.

7.Overall Cost and Price
Without quoting specific prices, it can be said that domestic equipment of comparable specifications is generally priced significantly lower than imported brands. As a domestic highend model, the AW600 strikes a balance between performance and price. For specific purchase pricing, please contact the manufacturer directly.

Purchasing Recommendations
The above is an objective introduction to the Beijing NOVICK AW600. When actually making a purchase, we suggest you:

1.Clarify your own needs: List the dimensions, materials, accuracy requirements, and expected output of your typical workpieces.

2.Request more manufacturer information: Ask for customer case studies from the last two years, especially applications in the same industry.

3.Arrange an onsite trial cut: Bring your own typical workpieces to the manufacturer or a local agent to verify accuracy and stability firsthand.

4.Compare service terms: Understand the warranty period, response time, spare parts pricing, etc.

No single manufacturer is suitable for every scenario. However, in the domestic Brass Wire Cut EDM field, the Beijing NOVICK AW600 is a machine worth including on your evaluation shortlist.
