What are the causes of dimensional issues in wire cutting? An explanation of the differences in thickness, die shape, and key points to check.
Hanshin Seiko Co., Ltd. has published a technical article titled "Causes of Dimension Issues in Wire Cutting | Checkpoints When Precision is Unstable." Issues such as "not achieving the desired dimensions," "dimensions differing between the top and bottom," and "only the intermediate section not matching the shape" highlight the importance of distinguishing whether there is a consistent dimensional deviation overall or if the shape of the machined surface is changing in the thickness direction. The article introduces factors to check, including correction amounts, wire deflection and vibration, machining fluids, material deformation, and temperature. It also explains our response examples, where we checked the top, middle, and bottom of thick materials and adjusted the machining feed rate and wire tension based on the measurement results. Please consider the approach of understanding the nature of the deviations and reviewing machining conditions rather than judging solely by correction values or the number of finishing passes. For inquiries regarding machining of thick materials with strict tolerances, please contact us with the drawings, material, thickness, and required precision. If you have already machined parts, please also provide the actual measurements and remaining machining allowances.
A stop screw hole with a depth of 6.5mm and M1.6 size is created in SUS304. The machining chips are repeatedly removed to maintain the discharge state all the way to the bottom of the hole.

Consultation on processing SUS304 | Confirmation items that change with thin plate test pieces and thick key grooves
We would like to introduce the technical information of Hanshin Seiko. When requesting wire cutting of SUS304, it is important to convey not only the material name but also the plate thickness, final shape, and the state before processing. The original article discusses tensile test specimens of SUS304H-SR with a thickness of 0.1mm and the keyway machining of a large SUS304 gear with a thickness of 300mm. For thin plates, the points of confirmation are the condition after holding and removal, while for thick materials, the alignment with respect to the thickness direction shape and tooth profile is the focus. The dimensions of these two examples are not presented as a uniform processing range. When consulting, please inform us of the detailed material code, plate thickness, contour and tolerances, and which existing tooth profile, hole, or finished surface to use as a reference in the drawings. You can also check the guidance for each case from the related links.

Wire cutting or shape engraving | Check from the through-hole, bottom contact, and the way the electrode enters.
We will introduce technical information for selecting construction methods. Wire cutting is mainly considered for through contours, while shape machining discharge is examined for blind holes and bottom shapes. However, it is not solely determined by the names of materials and shapes. The wire path, the direction in which tools and electrodes can approach, inner corner radii, tolerances, and quantities must also be checked. For shape machining discharge, it is necessary to prepare electrodes that correspond to the shapes. When comparing not only the time required for processing the product but also the preparation processes, it becomes easier to consult. The original article from Hanshin Seiko provides guidance on the overall diagrams and cross-sectional views needed for method comparison, as well as how to organize material and treatment conditions, current processes, and points of concern.
Specifications for non-standard side dimensions and position/orientation can also be discussed. Hexagonal through holes are available from single items or small lots.
