The machine-mounted harness is the “nerve pathway” of the CNC machine tool motion system. It accurately transmits control commands, sensor signals and power from the electrical cabinet to the spindle, turret, servo motors and various sensors, while withstanding drag-chain bending, oil-mist erosion and vibration shocks, ensuring that the machine still “beats” stably under complex working conditions.
II. Structure family
High-flex drag-chain harness Multi-strand fine copper + TPU sheath, resistant to bending and oil mist, suitable for high-speed drag-chains on Swiss-type lathes.
Servo power harness Three-phase power + shielding layer, anti-EMI, suitable for heavy cutting on turn-mill centres.
Sensor signal harness Shielded twisted pair + aluminum foil, anti-EMI, ensuring encoder and temperature sensor signals are distortion-free.
Control signal harness Shielded multi-core + color coding, suitable for PLC, HMI, I/O modules, plug-and-play.
III. On-site identification at a glance • Look at color: power red, signal blue, encoder green, function distinguishable at a glance. • Listen to sound: drag-chain runs without “sand” dry friction, harness sheath no cracking.
• Touch temperature rise: after continuous running, harness sheath only slightly warmer than body temperature, no hot-hand phenomenon.
IV. Maintenance “two-step method”
Each shift: visual inspection of harness in drag-chain, no twisting, no cracking; wipe sheath with damp cloth to prevent oil-mist accumulation.
Monthly: use infrared thermometer to detect harness temperature rise, stable means qualified; use feeler gauge to detect drag-chain gap, out of tolerance then adjust.
V. JSWAY Service • Factory-equipped “harness health ID”, scan code to check bending cycles and temperature rise curve. • Provide on-site harness re-calibration service, restore factory flexibility.
• Common drag-chain harness shipped within hours, reducing customer downtime waiting.
One-sentence summary
Treat the harness as the “nerve pathway” of the CNC machine tool — choose the right flexibility, adjust the shielding, clean frequently — so that every drag-chain bend is “no twisting, no cracking, no temperature rise”, this is yet another lifetime insurance JSWAY provides for your precision manufacturing.
