Production of tensile test specimens for thin plates | Plate thickness 0.1mm, wire cutting

Please consult us about thin sheet tensile test specimens with a thickness of 0.1mm. We take into account not only contour accuracy but also warping and scratches after holding, cutting, and removal.

At Hanshin Seiko, we accept the production of tensile test specimens from thin sheet metal based on drawing specifications using wire-cut electrical discharge machining. The article discusses the processing challenges and innovations when producing JIS Z 2241 Type 13B specimens from SUS304H-SR material with a thickness of 0.1mm. For thin sheets, it is important to consider warping and twisting during processing, as well as breakage and scratches during handling, in addition to maintaining stability during processing. We examine support using backing plates and layered cutting according to the condition of the material, while avoiding excessive tightening to ensure stable support until finishing. Attention is also given to the width of the parallel section, the connection with the shoulder radius, and the machining marks at the start and end of the cut. Additional finishing of the machined surface is considered based on applicable standards, drawings, and the requirements of the testing personnel. Please provide the material, heat treatment, thickness, sampling position and direction, quantity, and desired delivery date along with the drawings.
