In the realm of modern precision mold manufacturing and parts processing, the performance of machine tools directly determines a product's market competitiveness. Leveraging its deep industry expertise, Taizhou Xinchengyang Machinery Manufacturing Co., Ltd. has elevated the processing capabilities of its DK35BC High-Medium-speed WEDM to new heights. This equipment not only embodies the core advantages of medium-speed wire-cut technology but also achieves significant breakthroughs in both operational stability and machined surface quality.
Core Technical Architecture and Performance
Coordinated Control of Digital Pulse Power Supply
The DK35BC's ability to achieve exceptionally high surface finishes during processing stems from Taizhou Xinchengyang's meticulous fine-tuning of the pulse power supply system. By ensuring a stable output of high-frequency energy, the machine maintains an optimal balance within the discharge gap; this effectively minimizes electrode wire wear and ensures the uniformity of discharge traces on the workpiece surface. This specific control logic serves as the fundamental basis for executing multi-pass cutting operations and achieving superior surface roughness levels.
Vibration Resistance and Thermal Stability of Mechanical Structure
High-precision machining is impossible without a mechanical body possessing exceptional rigidity. The DK35BC features a reinforced cast-iron machine bed that has undergone an extended period of natural aging treatment. This treatment process eliminates internal casting stresses, ensuring that the machine tool maintains constant geometric precision even during prolonged periods of high-speed reciprocating motion. For long-path cutting tasks, this thermal stability effectively prevents machining deviations caused by fluctuations in ambient temperature.
Intelligent Wire-Path Constant Tension System
Fluctuations in electrode wire tension are a critical factor affecting perpendicularity and the occurrence of surface striations. In the design of the DK35BC, Taizhou Xinchengyang has incorporated a constant tension control mechanism; whether during wire feeding startup, direction reversal, or the standard cutting phase, the system adjusts tension in real-time to ensure the electrode wire remains in an ideal state of tautness. This not only enhances cutting efficiency but also demonstrates exceptional vibration-damping capabilities when processing heavy or thick workpieces.
Multi-Stage Filtration and Efficient Cooling Circulation
The cleanliness of the dielectric fluid directly influences the stability of the electrical discharge process. The DK35BC is equipped with a highly efficient filtration system capable of rapidly separating metal debris generated during machining operations. An effective cooling environment not only dissipates the high temperatures generated during the discharge process but also facilitates excellent chip removal, thereby preventing secondary discharges from damaging the machined surface and ensuring consistent machining precision.

Taizhou Xinchengyang Machinery Manufacturing Co., Ltd.: Expert Technical Support and Q&A
In actual production environments, selecting the appropriate machining parameters and maintaining the machine tool are critical concerns for every customer. The following is a compilation of frequently asked technical questions regarding the DK35BC medium-speed wire-cut EDM machine.
FAQ
Q: How does the DK35BC ensure verticality when processing large, heavy molds?
A: This is primarily achieved through the machine tool's reinforced support structure and precision guide rails. During the assembly process, Taizhou Xinchengyang places extremely high demands on the machine's leveling accuracy; combined with a constant-tension system, this ensures that the electrode wire does not deflect during the machining of thick workpieces, thereby guaranteeing dimensional consistency between the upper and lower surfaces.
Q: How is the multi-cut process (trim cutting) implemented on the DK35BC?
A: Trim cutting is achieved by adjusting the discharge energy and wire feed speed to perform secondary—or even multiple—finishing passes following the initial rough cut. The first pass is primarily responsible for rapid material removal using high current, while subsequent passes utilize lower current and slower speeds, focusing on eliminating the surface recast layer and refining the contour accuracy.
Q: How can one effectively extend the service life of the guide wheels and bearings on the DK35BC?
A: The key lies in proper lubrication and cleaning. We recommend periodically cleaning carbon deposits from the wire-guide assembly and using high-quality cutting fluid. Taizhou Xinchengyang's equipment features specialized protective designs for critical rotating components; provided that periodic maintenance is performed as scheduled, the precision retention of these guide components remains exceptionally durable.
Q: How does the concentration of the cutting fluid affect the machining efficiency of the DK35BC?
A: If the cutting fluid concentration is too high, it hinders chip evacuation efficiency; conversely, if it is too low, it compromises rust prevention capabilities and discharge stability. When machining different materials (such as aluminum or mold steel), the mixture ratio should be fine-tuned based on the material's electrical conductivity and chip-removal characteristics to achieve the optimal discharge frequency.
Q: Is the DK35BC capable of cutting ultra-tall or irregularly shaped workpieces?
A: By utilizing extended height supports and a 4-axis (or 5-axis) simultaneous control configuration, the DK35BC can easily handle taper cutting and the machining of ultra-tall workpieces. Taizhou Xinchengyang can provide customized structural reinforcement solutions based on the specific dimensions of the customer's workpieces.
