The molybdenum wire electrical discharge machining (EDM) machine features a mechanism that allows the same wire to be used in both forward and reverse directions in a circulating manner. Unlike brass wire, which is designed for single use, this system reduces the frequency of wire replacement, significantly lowering running costs. However, due to the structure that circulates the wire, there were challenges in setup, particularly with the "wiring work." In internal diameter processing, human intervention was required to thread the wire through the workpiece's pilot hole and perform the wiring, making unmanned operation during nights and holidays difficult. The new HG series has achieved automatic wiring with molybdenum wire through a uniquely developed mechanism, eliminating the need for operators to be constantly present at the machine. Running costs have been halved, and operators are freed from wiring tasks. These two previously conflicting elements are now balanced in the HG series. We will be exhibiting this HG400 for the first time at "JIMTOF2026 (the 33rd Japan International Machine Tool Fair)" to be held at Tokyo Big Sight from October 26 (Monday) to October 31 (Saturday), 2026. Exhibition location: East Hall 7, Booth Number E7075 We sincerely look forward to your visit.

In the mold manufacturing industry, high precision and efficient processing are required for machining complex-shaped parts. Particularly in the processing of fine shapes and deep cavities, the setup and replacement of wires are factors that influence productivity. Conventional molybdenum wire electrical discharge machines require manual labor for connection work in exchange for low-cost operation, hindering unmanned operation. The new HG series achieves automatic wire connection with molybdenum wire through a uniquely developed mechanism, reducing the burden on operators. This enables a reduction in running costs while improving work efficiency. 【Usage Scenarios】 - Machining of complex-shaped mold parts - Automation of wire threading and connection work in inner diameter processing - Increased productivity through unmanned operation during nights and holidays 【Benefits of Implementation】 - Significant reduction in running costs - Reduced burden on operators by freeing them from connection work - Improvement in productivity and operational rates

In the automotive industry's precision parts manufacturing, high accuracy and production efficiency are required. Particularly for parts that require complex shapes and fine processing, reducing machining time and controlling running costs become significant challenges. Conventional molybdenum wire electrical discharge machines can minimize wire replacement frequency, but they often require human resources for connection work, which can hinder unmanned operation. The new HG series, with its uniquely developed mechanism, achieves automatic connection using molybdenum wire, thereby reducing the burden on operators. This enables a balance between low-cost operation and improved work efficiency, contributing to increased productivity in automotive parts manufacturing. 【Usage Scenarios】 - Manufacturing precision parts for automotive devices - Inner diameter processing of complex-shaped parts - Productivity improvement through unmanned operation during nights and holidays 【Benefits of Implementation】 - Reduction in running costs (suppression of wire replacement frequency) - Labor-saving through liberation from connection work - Improvement in production efficiency

In the fields of research and development and prototyping, there is a need to process complex-shaped parts accurately and quickly. Especially in the prototyping stage, it is essential to respond to design changes and validate multiple patterns in a short period, making the reduction of processing time and the efficiency of setup work important. However, conventional molybdenum wire electrical discharge machines required manual intervention for wire connection, which hindered unmanned operation. The new HG series achieves automatic wire connection with molybdenum wire through a uniquely developed mechanism, eliminating the need for operators to be constantly present at the machine. This allows for the coexistence of previously conflicting elements: reducing running costs and freeing operators from wire connection tasks, thereby supporting the efficiency of prototyping in research and development. 【Usage Scenarios】 - Prototyping of complex-shaped parts - Validation of multiple patterns in a short period - Quick response to design changes 【Benefits of Implementation】 - Reduction of prototyping lead time - Decreased workload for operators - Lower running costs

In the semiconductor manufacturing industry and precision machining, high-precision component processing is required. In particular, when processing fine circuit patterns or components with complex shapes, a stable supply of wire and accurate connections significantly impact processing quality and production efficiency. Conventional molybdenum wire electrical discharge machines required manual labor for connection work in exchange for low operating costs, which sometimes hindered unmanned operation. The new HG series achieves automatic connections with molybdenum wire through a uniquely developed mechanism, reducing the burden on operators.

In the field of architectural hardware, high precision and efficiency are required for processing complex special shapes. Particularly for products that pursue design and functionality, there are many shapes that are difficult to handle with conventional processing methods. In response to these challenges, a molybdenum wire electrical discharge machine that reduces wire replacement frequency and lowers running costs becomes an effective option; however, manual labor is still needed for wiring tasks, which can hinder unmanned operation. The new HG series achieves automatic wiring with molybdenum wire through a uniquely developed mechanism, thereby reducing the burden on operators. 【Application Scenes】 - Manufacturing architectural hardware with complex designs - Processing parts with special functions - Production of prototypes 【Effects of Implementation】 - Reduction of running costs - Labor savings by freeing from wiring tasks - Improvement in productivity
