1. Materials and Structural Parameters
Shanghai Sohke CNC Drag Chain Ultra-Flexible Cable (3 Core / 4 Core / 5 Core) Product Details 1. Brand Strength Display Shanghai Sohke has been devoted to the wire and cable field, establishing an outstanding brand image with its professional R&D team, advanced production equipment, and strict quality control system. The company always upholds the spirit of innovation, closely monitors industry trends and customer needs, continuously introduces new products, provides high-quality cable solutions for various industries, and has earned a good reputation and high recognition within the industry.
II. Detailed Analysis of Product Structure (1) Conductor High-purity oxygen-free copper is carefully selected and crafted through a meticulously multi-strand twisting process. This structure gives the cable outstanding flexibility, allowing it to easily withstand frequent bending and twisting actions in CNC drag chains, effectively preventing the risk of core breakage. At the same time, the excellent electrical conductivity of high-purity oxygen-free copper significantly reduces resistance, ensuring efficient and stable power transmission, providing a solid electrical foundation for the stable operation of CNC equipment.
(2) Insulation Layer: Made of specially formulated polymer insulating material, it possesses excellent electrical insulation properties, can withstand high voltage, and effectively prevents current leakage to ensure electrical safety. Moreover, this insulating material has outstanding wear resistance and chemical corrosion resistance, capable of withstanding chemical substances commonly found in CNC machining environments, such as cutting fluids and oil stains, thereby extending the service life of the cable.
(3) Shielding Layer (for some models) For CNC work environments with complex electromagnetic interference, some cables are equipped with a shielding layer. Aluminum foil shielding can effectively block low-frequency interference, while tinned copper braided shielding excels at defending against high-frequency interference. The combination of the two greatly enhances the cable's anti-interference capability, ensuring accurate and stable signal transmission within the cable. It is especially suitable for CNC systems that demand extremely high signal transmission quality, such as the control systems of high-precision CNC machine tools.
(4) Sheath The outer sheath is made of special rubber or polyurethane materials with high strength and high wear resistance. Its superior wear resistance can withstand the friction with surrounding components when the CNC drag chain moves at high speed and high frequency; excellent oil resistance can effectively resist oil corrosion, meeting the needs of CNC workshops with oily environments; outstanding weather resistance allows it to maintain good flexibility and physical properties over a wide temperature range from -40°C to 80°C, ensuring stable operation in both severe cold and extreme heat.
3. Product Performance Highlights (1) Ultra-High Flexibility and Bend Resistance With special design optimization, the bending radius can be as low as 6-8D (D being the cable outer diameter), allowing frequent and large-angle bending in confined spaces, perfectly matching the complex motion trajectories of CNC drag chains. Laboratory simulations of over 10 million bending cycles show that the cable structure remains intact and performance indicators stay stable as initially, greatly reducing failures caused by cable bending fatigue and significantly enhancing the reliability and stability of CNC equipment operation.
(2) Strong Tensile and Torsional Resistance Fully considering the tensile and torsional forces the cable endures during the operation of the CNC drag chain, high-strength reinforcing cores, such as aramid fibers or high-strength steel wires, are specially added inside, significantly enhancing the cable’s tensile and torsional performance. In actual use, even when CNC equipment starts and stops quickly or accelerates and decelerates abruptly, generating strong tensile and torsional forces on the cable, the cable can maintain structural stability without breaking, twisting, or deforming, ensuring smooth operation of the equipment.
(3) Excellent anti-interference and signal transmission Cables equipped with shielding layers perform exceptionally well in strong electromagnetic interference environments. They can effectively shield electromagnetic radiation from the CNC equipment's own electrical system, as well as interference signals generated by surrounding electronic devices, ensuring the CNC system's signal transmission is accurate and reliable. This prevents equipment from misoperating, a decline in machining precision, or even downtime due to signal interference, ensuring high precision and safety in CNC machining.
(4) Long Lifespan and High Reliability: Relying on high-quality raw materials and advanced manufacturing processes, the products have a long service life. Under normal working conditions, the designed service life can reach more than 10 years. Moreover, the products undergo rigorous quality testing, covering electrical performance, mechanical performance, environmental adaptability, and other aspects. Each cable possesses high reliability and can operate stably over the long term in complex and harsh CNC machining environments, significantly reducing equipment downtime and maintenance costs caused by cable failures, thereby creating greater value for users.
4. Application Scenario Adaptation (1) CNC Machine Tool Machining During CNC machine milling, turning, drilling, and other machining processes, cables need to be frequently moved and bent along with drag chains. Shanghai Suo Qi's CNC drag chain ultra-flexible cables precisely meet this requirement, providing stable power and signal transmission for all machine tool components, ensuring precise tool positioning and spindle stable operation, achieving high-precision part machining, and improving production efficiency and product quality.
