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.

1. Surface Roughness Comparison This is a comparison table of surface roughness for each cutting count in our wire cut machine, the HB series. - The first cut has a roughness of about Rz22. - Multi-cut (multiple processing) achieves a roughness of about Rz4.8. 2. Multi-Cut in the HB Series While it is slightly inferior to brass wire cutting, the multi-cut (multiple processing) guarantees a precision of ±0.01. The HB series machine is themed around "speed and cost-effectiveness," so if ±0.01 is sufficient for your wire processing needs, we recommend this machine.

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.

Business owners, please take a moment to watch this video. Why can factories in China process at low prices despite soaring labor costs? I visited several manufacturers in Shenzhen to investigate this question. There, I saw processing machines that I had never seen in Japan. One of them was a reverse wire cut using molybdenum wire. In Japan, wire cutting is typically used only for key grooves or precision holes, but in China, this machine was used to create shapes by sparking instead of milling. After watching the video, please consider acquiring one of these machines.

Production equipment parts often have special surface treatments and precision machining applied to each individual component, resulting in a significantly high added value for each part, which is not uncommon compared to parts for products. However, on the other hand, there are many cases where high-specification requirements lead to the continued use of difficult-to-process materials from the past. In such cases, it is possible to improve QCD by replacing them with other materials currently available or new materials. [Case Study] ■ VE through material change of aluminum <Before (Work Condition, Material: A7075, Surface Treatment: None)> - Processing with A7075 tends to result in warping. - Rough machining and finishing are required, leading to increased costs. <After (Work Condition, Material: A6061, Surface Treatment: None)> - Adopted A6061, which is less prone to warping among aluminum materials. - Hardness slightly decreased, but machining costs were reduced. *For more details, please refer to the PDF document or feel free to contact us.

Production equipment parts often undergo special surface treatments and precision machining for each individual component, making their added value exceptionally high compared to parts for general products. It is not uncommon for such parts to have significant added value. In cases where components like shafts or spindles of production equipment, or punches and nozzles of molds wear out or break and need to be replaced with new ones, Ohno Seiko's "Parts Regeneration (Reverse Engineering) Service" can be very helpful. 【Processing Example】 ■ Parts regeneration of claw components for production equipment <Before (Work Condition, Material: S45C, Surface Treatment: High-Frequency Hardening)> - Replacement due to wear on only part of the claw component - Request for shortened delivery time and cost reduction with only partial correction <After (Work Condition, Material: S45C, Surface Treatment: Laser Cladding)> - Adoption of laser cladding with minimal thermal distortion - Correction with only partial machining - Delivery time shortened by about one week - Lifespan is nearly equivalent, resulting in significant cost reduction *For more details, please refer to the PDF document or feel free to contact us.
