35mm Inner Height Series

CNC Drag Chain 35mm Series – Enclosed Glass-Fiber Reinforced Nylon

Total Swarf Protection & Superior Performance for CNC Machinery

In mid-to-heavy machining environments with flying hot swarf, abrasive wood dust, and high-pressure coolant spray, protecting moving cables is crucial. The 35mm series fully enclosed cnc drag chain is precision-engineered for CNC machining centers, woodworking routers, laser cutting machines, and automated production lines. Featuring a completely sealed covered outer structure, it forms an impenetrable barrier that prevents hot metal chips and grinding debris from invading the track channel, eliminating cable jacket abrasion and unexpected downtime.

Featuring a 35mm internal clearance height and support for internal widths from 50mm up to 150mm, this high-performance cnc drag chain effortlessly houses motor power cables, high-flex signal lines, and pneumatic conduits up to 28mm outer diameter, maintaining superior alignment and anti-sagging stability across medium-to-long movement paths.

Note: Popular bending radius choices for the 35mm series include R75, R100, and R125. For inner widths exceeding 75mm, selecting R100 or larger is recommended for optimal flex dynamic control.

Premium Material: 30% Glass-Fiber PA66 Reinforced Nylon

Material composition directly governs long-term carrier durability under continuous flexing. Every link of our 35mm enclosed cnc drag chain is precision injection-molded from **PA66 nylon heavily reinforced with 30% glass fiber**, delivering superior mechanical properties compared to standard plastic tracks:

Complete Chip & Debris Shielding: Precision snap-open covers lock tightly, blocking hot metal swarf, wood dust, fine abrasive powder, and direct coolant spray.
Maximum Tensile Rigidity & Flex Strength: Glass-fiber reinforcement dramatically increases flexural modulus, preventing link sagging across long unsupported travel strokes.
10 Million+ Flex Fatigue Service Life: High pin-to-hole surface hardness minimizes friction, guaranteeing smooth operation exceeding 10 million flexing cycles.
Wide Thermal Range: Performs reliably across operating temperatures from -40°C up to +130°C without softening under machining heat or becoming brittle in cold climates.
Chemical & Oil Resistance: Highly resistant to cutting fluids, synthetic lubricants, hydraulic oils, and mild chemical agents.
Quiet Operation: Flame-retardant rated **UL94 V-2**, with built-in acoustic damping keeping running noise below **60dB**.

Enclosed Structure & Maintenance Advantages

The enclosed design features quick-release snap-open lids along the outer radius that flip open easily using a standard flathead screwdriver:

Fast Cable Harnessing: Maintenance crews can lay pre-assembled cable harnesses directly into the track channel, eliminating tedious thread-pulling through tight tubes.
Smooth Cable Cavity: Radiused inner contours prevent outer jacket abrasion on sensitive encoder cables during high-speed acceleration.
Lightweight Drive Strain Reduction: Weighs roughly one-third of steel conduits, lowering drive motor strain and enabling faster axis acceleration rates.

Target Applications & Compatible Machinery

This heavy-duty enclosed cnc drag chain serves as a reliable energy chain system for demanding equipment operating in dirty environments, including:

CNC Machining Centers & Lathes: Protects motor power and feedback wiring against flying hot steel and aluminum swarf.
Woodworking CNC Routers: Blocks fine sawdust and wood chips from clogging the carrier link joints.
Laser, Plasma & Waterjet Tables: Shield gas lines and fiber optic lines against hot sparks and slag.
Stone & Marble Engravers: Prevents stone dust and wet slurry from entering the internal cable channel.
