[Processing Example] Machining with Wire Electrical Discharge Machining to Minimize Heat Affected Zone
Completed while keeping both the delivery time and costs down! Here we present a case study of processing SK85 (SK5 / carbon tool steel).
This time, we will introduce a case of blank cutting and simple mold creation using a wire electrical discharge machine. Since the material is SK85 (SK5 / carbon tool steel), choosing laser cutting raises concerns about hardening of the cross-section due to heat during processing, which may lead to the occurrence of fine cracks. Therefore, we performed blank cutting using wire electrical discharge machining, which has minimal thermal impact, thereby addressing this concern. We were also able to complete the project while keeping both the delivery time and costs down. 【Case Overview】 ■ Material: SK85 (SK5) ■ Size: 15×18×5mm ■ Thickness: t0.3 ■ Precision: ±0.05 ■ Quantity: 100 ■ Delivery Time: 5 days *For more details, please refer to the PDF document or feel free to contact us.

Company information
At Nishino Seiki Seisakusho Co., Ltd., we have a wide range of equipment and systems that can handle both sheet metal and press processing, as well as machining such as lathes and machining centers, allowing us to comprehensively meet all customer requests for prototypes and parts processing. We also manufacture dedicated molds and tools necessary for processing prototypes and products requested by customers, such as bending molds, punching molds, and drawing molds, in-house. This eliminates the need to outsource mold production, enabling us to achieve shorter lead times for processing. Additionally, we can quickly make creative adjustments, fine-tuning, and improvements to molds in-house, which significantly enhances the quality and precision of the finished products. We cover both sheet metal and press processing as well as machining within a single company, leveraging our uniquely developed processing technologies and know-how to challenge ourselves daily with the processing of fine, miniature parts and difficult materials.
