Control cable failure in CNC machines kills uptime. Cheap cables crack inside drag chains after weeks, overheat near servo motors, and signal crosstalk causes axis positioning errors. Replacing downtime costs far more than the cable itself. This 26-core 1.25mm² cable from NAGAOKA Japan is built to survive real machine tool conditions — not just pass a lab test.What This Cable IsAn imported multi-core control and power cable designed for CNC machine tool motor circuits. Pure copper Class 5 conductors carry stable power and control signals through high-flex zones, oil-splash areas, and heat near spindle motors. NAGAOKA manufactures it to JIS C 3401 standards with batch-level quality checks.Core Parameters

Why It Performs Where Cheap Cables Fail
- Drag chain tested to 10M+ cycles. Bent at 15mm radius under continuous CNC axis movement — no conductor breakage, no insulation cracking. This is the #1 failure point in machine tool wiring.
- Pure copper, not CCA. Lower DC resistance means less heat buildup near servo and spindle motors. Voltage drop stays under 3% even at full motor load across 20m runs.
- Oil and coolant resistant jacket. PVC compound withstands cutting fluid, hydraulic oil, and water splash — standard in machining centers, grinders, and EDM machines.
- NAGAOKA batch testing. Every spool tested for insulation resistance (≥100MΩ·km), conductor continuity, and flexibility before packing. No surprises on your floor.
