Introduction
Product Introduction
The Automobile Wire Corrugated Pipe Drag Grinding Machine is specifically designed to evaluate the abrasion resistance of automotive wires and corrugated tubing. The instrument simulates realistic mechanical stress by performing controlled scraping tests, ensuring reliable assessment of insulation durability and material performance. The machine features automatic stopping when the scraper penetrates the insulation and contacts the conductor, ensuring both safety and consistent test results.

FAQ
Q: What types of samples can this machine test?
A: It is suitable for automotive wires and corrugated tubing with standard diameters used in vehicles.
Q: How does the machine ensure uniform scraping?
A: The scraper moves in a U-shaped path to avoid uneven abrasion and unilateral wear.
Q: Can the load be customized for different test requirements?
A: Yes, loads can be set from 4 N (basic) to 11 N, depending on the test specification.
Q: What safety measures are included?
A: The machine automatically stops if the scraper penetrates the insulation, and the test area is enclosed to prevent operator injury.
Q: How is testing affected by environmental temperature?
A: The machine monitors ambient temperature; testing cannot start if it falls outside 23 °C ±1 °C, ensuring accurate and repeatable results.
