If the workpiece is conductive, it is possible to drill holes in materials of any hardness!
Tsukada Co., Ltd.'s "Fine Hole Electric Discharge Machining" uses fine hole electric discharge machines to create small holes in hardened materials, etc. The basic diameter uses a 1mm electrode, but by changing the chuck, it can accommodate diameters from φ0.5 to φ3.0mm. *Diameter accuracy is not very precise. (Using a φ0.5 electrode may result in variations of φ0.6 to φ0.7) 【Features】 ■ It is possible to drill holes in any hardness of workpiece that conducts electricity. ■ If a tool breaks and becomes stuck during drilling or tapping, it can be removed using fine hole electric discharge machining. *For more details, please download the PDF or feel free to contact us.

Company information
Tsukada Co., Ltd. has been engaged in press punching and bending processing of cutting tools such as scissors, knives, and nail clippers, as well as drawing processing for covers that conceal drainage pipes used in water areas since its establishment in 1970. We also manufacture the molds necessary for press processing. Equipped with three-dimensional measuring machines and image dimension measuring devices, we have consistently internalized the entire process from mold design to processing assembly. This allows us to accept transfer molds, even those made during the Showa era, with minimal necessary modifications using reverse engineering techniques. In recent years, many molds have been transferred to Tsukada Press due to the aging of representatives from long-established press companies and the lack of successors. We can digitize even the oldest molds using three-dimensional measuring machines, ensuring a smooth production transfer. We can accommodate production lots ranging from hundreds to hundreds of thousands. Please feel free to contact us.
