沙迪克以超细线电火花加工探索微型精密零件新可能，AP250 可用 30 微米丝
Sodick explores new possibilities with ultra-fine wire EDM
沙迪克（Sodick）介绍其油基线切割电火花技术如何应对微型精密零件加工需求，应用场景包括高端制表。正文以直径仅 10 微米（0.01 mm）的电极丝说明细线加工的尺度，并提到 AP250 机型使用 30 微米丝，另有经专门改装的设备可处理细至 10 微米的丝。沙迪克德国公司的 Giuseppe Addelia 在接受 MTDCNC 的 Rowan Easter-Robinson 采访时讲解了这些挑战及应对方式。油基线切割通过受控放电去除导电工件材料，加工时无常规切削力作用于零件，适合 delicate 轮廓与精细特征；细线可进入更小细节和更紧的内部几何。文中强调，10 微米和 30 微米指切割丝本身直径，不应与成品尺寸公差混淆。要在这一尺度稳定加工，还需精确的机床运动、可靠的走丝处理、受控放电能量与稳定加工条件配合。AP250 配 30 微米丝与处理 10 微米丝所需专门改装属不同配置，应结合具体零件、材料和生产要求选择。沙迪克欧洲与区域团队及合作伙伴协助制造商评估应用并确定合适加工方案。
Sodick’s oil-based wire EDM technology is helping manufacturers address the demanding requirements of miniature precision components, with applications including luxury watchmaking.
Wire just 10 microns in diameter — equivalent to 0.01mm — illustrates the extraordinary scale of fine-wire machining. For manufacturers producing intricate watch components, technology at this level opens up possibilities for exceptionally small and detailed features.
In a conversation with MTDCNC’s Rowan Easter-Robinson, our colleague Giuseppe Addelia from Sodick Deutschland explains how Sodick approaches these challenges, discussing the AP250 using 30-micron wire alongside specially modified machines capable of handling wire as fine as 10 microns.
Meeting the demands of watchmaking
Luxury watchmaking brings together miniature dimensions, complex geometry and exacting expectations for accuracy and surface quality. Producing these components requires careful control throughout the machining process.
Our oil-based wire EDM technology uses controlled electrical discharges to remove material from an electrically conductive workpiece. With no conventional cutting forces acting on the component, the process is well suited to delicate profiles and intricate features.
Fine wire enables access to smaller details and tighter internal geometries. The wire diameters discussed in the interview describe the cutting wire itself; they should not be confused with the dimensional tolerance of the finished component.
Technology and expertise working together
Successfully machining at this scale requires more than a fine wire. Precise machine movement, reliable wire handling, controlled discharge energy and stable machining conditions must work together to achieve the required result.
Giuseppe’s explanation provides an insight into how these factors support demanding applications, where even a small feature can play a critical role in a component’s performance.
The interview also distinguishes between the AP250 operating with 30-micron wire and the specialist modifications required to handle 10-micron wire. These configurations should be considered around the specific component, material and production requirements.
Supporting precision manufacturers across Europe
At Sodick Europe, we work with our regional teams and partners to help manufacturers assess their applications and identify an appropriate machining solution.
