According to the technical requirements of high-speed winding and slitting: the deflection value of the middle end of the steel coil core must be ≤0.3mm when the speed is 0-300rpm, and the deflection value must be ≤0.6mm when the speed is 300rpm-700rpm.
The company has exclusively developed a special "non-contact dynamic deflection testing and processing system", which has been applied in the production of a large number of steel coil cores and has achieved good results.
Recording surface: 80% of the steel coil core, under the condition of machining and dynamic balance, its dynamic deflection value is 3-5mm, and it must be processed by the system to meet the requirements.
