漆包线漆膜耐磨性测试设备
By designing a device for testing the abrasion resistance of enameled wire coatings, an environmental control component is used to maintain a stable environment inside the chamber and reduce external interference. The enameled wire is fixed by a fixture, and the coating thickness change is automatically detected by a friction mechanism and a laser rangefinder. This solves the problems of low efficiency and poor accuracy of existing equipment and achieves efficient and accurate abrasion resistance testing.
