• Electric discharge machine

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.

• Cutting Oil

The work created with a metal 3D printer ultimately requires a process to separate it from the support material. The most commonly used equipment for the separation process is often reported to be wire cutting or saw blades. However, separating with brass wire cutting takes time, which inevitably increases the cost per workpiece. In contrast, using saw blades can easily dull the blade and tie up the operator's time. How can we improve this situation? Among various proposals, many customers are utilizing our "CNC Molybdenum Wire Electric Discharge Machine," which we sell. It allows for automation through NC control, and by repeatedly using molybdenum wire, which has superior toughness compared to brass wire, we can offer speedy and low-cost processing for thick or intermittent-shaped workpieces. Please consider it at least once. *We also accept test cuts.

There are two main reasons why customers choose this machine! 1. They want to reduce the processing costs of wire electrical discharge machining to increase profits. 2. They are struggling with machining difficult-to-cut materials and want a device that can easily process these materials. This time, I will explain the first point regarding reducing processing costs. The biggest challenge customers face with wire electrical discharge machining is the cost of the wire. The structure that uses new wire constantly as a disposable leads to significant consumption of brass wire, which is suitable for high-precision machining but results in high costs for other types of machining. The solution to this problem is our "HB Series" that we sell. The feature of this machine lies in its mechanical structure. A drum is installed at the rear of the machine, and by rotating the drum that is wrapped with wire in both directions, it enables the repeated use of the wire. Naturally, the wire will wear out, so the precision will be around 0.01, but the processing cost is overwhelmingly low, leading to significant profit increases in applications other than high-precision machining. Customer feedback includes statements such as being able to win estimates against other companies in wire processing and leading to new transactions.

For wire cutting processing, it is necessary to adjust by inserting shims to ensure the workpiece is parallel. The parallelism of the workpiece has a significant impact on the final product finish, so the processor spends a lot of time on this setup. It is a time-consuming and tedious task. However, since the machine is not operating during setup, from a management perspective, it is preferable to minimize the time spent on this... The solution to this is our designed and developed leveling base, the "PAD series"! It can easily resolve the leveling required for the pre-setup of wire cutting, which has previously taken a lot of time, with just this one product! By adopting precision balls at the support points, the independence of each adjustment axis is high, making it easy to adjust without affecting the results of other axes. Additionally, it has high durability due to simplified structure and a design that prevents foreign objects from entering the spring components. 【Features】 ■ Easily resolves leveling tasks ■ Significantly improves setup efficiency ■ High durability *For more details, please refer to the PDF document or feel free to contact us.
