The ZNC-series EDM Sinker is a highly cost-effective single-axis CNC (Z-axis controlled) EDM solution, making it an ideal choice for the manufacturing of precision molds and the machining of complex metal parts. Utilizing the principle of spark discharge erosion to process conductive materials, this machine excels particularly at creating complex cavities, deep slots, sharp-angled structures, and parts made from hardened steel—features that are often difficult to achieve using traditional cutting methods.
The machine's Z-axis is equipped with an automatic servo control system capable of maintaining a precise and stable discharge gap, while the X and Y axes operate in a manual mode to facilitate flexible positioning. Integrated with an intelligent control system, the machine features built-in preset machining parameters for various materials—including copper, graphite, and steel—thereby ensuring high processing efficiency, superior surface finish, and minimal electrode wear. Its robust cast-iron construction provides exceptional rigidity and vibration resistance, effectively guaranteeing long-term machining precision.
This machine is widely utilized within the mold manufacturing industry, encompassing the production of injection molds, die-casting molds, forging dies, and stamping dies. Furthermore, it is well-suited for the precision machining and manufacturing of mechanical components, aerospace parts, and medical devices.

Frequently Asked Questions
What factors should I consider when selecting the right machine?
When choosing a machine, first match the worktable travel and cutting capacity to the size and thickness of your workpiece to identify a suitable model. Additionally, verify whether the precision and surface finish meet your standards.
The standard voltage in our country is three-phase 220V (or single-phase 220V, etc.), but your machine uses three-phase 380V. Is voltage adjustment possible?
Absolutely. Just let us know your specific voltage requirements, and we can customize the machine accordingly.
What details do you need from us to prepare a proposal?
We'll need the worktable dimensions, required travel range, and any special requirements you may have.
Are you a manufacturer or a trading company?
We specialize in manufacturing CNC machine tools and have over 20 years of experience in this industry.
