Machine Introduction
Wi-200S is the smallest submerged-type Wire-Cut EDM machine developed by JSEDM and is also one of the most compact wire-cut machines available on the market. The maximum machining stroke is 210 × 200 × 155 mm, making it particularly suitable for small precision parts and micro-machining applications.
For applications requiring taper cutting on both upper and lower profiles, the machine can achieve ±22.5° large-angle taper cutting with a 70 mm workpiece height, providing highly flexible precision machining capability.
The core design concept of the Wi-200S is to manufacture high-precision components with lower machining cost, making it especially suitable for small precision parts and high value-added products. Below are three application examples:
- The first example is Precision Jewelry Mold Machining, In jewelry pendant mold manufacturing, molds often feature small holes, multiple cavities, and high-precision corner radii requirements. Since these molds are relatively small in size, the Wi-200S combined with an automatic wire threading system can achieve high-precision and automated machining while reducing production cost, making it ideal for jewelry molds and precision micro-mold manufacturing.
- The second example is Precision Mechanical Watch Gear Machining. In the mechanical watch industry, precision gears are extremely small and require very high machining accuracy. These components typically require 0.1 mm diameter wire electrodes for cutting, with strict requirements on gear tip sharpness, root radius, and burr-free finishing. Even a small deviation may affect the timekeeping accuracy of the watch. The Wi-200S provides stable and high-precision micro-machining capability, making it well suited for precision gears and miniature mechanical components.
- The third example is Aluminum Extrusion Die Machining,Aluminum extrusion products are widely used in semiconductor equipment, automation systems, and the construction industry. These dies are usually small in size but require strict surface roughness control and uniform surface finishing. The Wi-200S can stably machine aluminum extrusion dies, ensuring consistent product appearance and machining quality.
In addition to machining tool steel and mold steel, the Wi-200S can also be applied to various materials through different machining techniques, including copper, brass, aluminum, as well as difficult-to-machine materials such as tungsten carbide and polycrystalline diamond (PCD).
High-Rigidity Structure:

- The machine body utilizes CAE (Computer-Aided Engineering) to simulate structural deformation of each axis during actual operation. Therefore, we use a high-rigidity T-shaped machine body structure to reduce load and thermal deformation issues, ensuring permanent mechanical accuracy.
- Casting was made from Meehanite cast iron, stress-relieved through heat treatment, it features a high-rigidity, symmetrically balanced design to reduce load and thermal deformation.
- The overall transmission structure employs a high-power AC (400W) servo motor, paired with Taiwan's PMI ballscrew and linear guides, this combination greatly reduces rotational errors. And with the adjustment of pitch compensation and backlash compensation in the control system, it ensures the precision of the machine's movement.
High-Precision Drive Shaft System:

The drive shaft uses highly precise "double nut" ball screws to achieve high rigidity, smooth operation, and minimal lead error. It is equipped with a high-torque, high-response AC (400W) servo motor, with an optional Fagor high-resolution optical scale for full closed-loop control. The optical scales are installed as close to the ball screws as possible, ensuring each axis maintains high precision, long life, and excellent stability.
Self-developed Wire Delivery System:

- The special structural design, combine with high-hardness ceramic pully, results in less wear and longer lifespan.
- With Japanese Panasonic AC servo motors, magnetic powder clutches, wire collection motors, and wire clamping mechanisms, the system can accurately make adjustment for instability caused by wire vibrations, ensuring stable wire delivery and low failure rates.
- The wire delivery system uses advanced constant tension motors for copper wire, it assures tension stability at all times and prevent copper wire entanglement caused by sudden breaks during normal operation.
- The wire delivery section utilizes a conduit-style collection structure. During threading, high-pressure fluid flow guides the copper wire to complete the threading process quickly within 3-5 seconds. Additionally, the use of high-quality ceramic wheel mechanisms ensures minimal wear over long-term use, eliminating the need for additional parts. Even ∅0.1mm copper wire can pass through easily without tangling.
