Product Description:
HUAO spherical alumina grinding ball is a core consumable developed by the brand specifically for precision grinding scenarios, focusing on the high requirements for grinding accuracy, stability, and efficiency in industries such as electronic ceramics, precision metallurgy, and optical glass. It solves the pain points of easy cracking and low efficiency in precision grinding of ordinary grinding balls. After being adopted by a certain electronic ceramic enterprise, the precision grinding accuracy compliance rate of precision blanks has increased from 86% to 99%, and the grinding cycle has been shortened by 30%, fully demonstrating the performance advantages of "HUAO Intelligent Manufacturing".
Features:
Adopting HUAO exclusive isostatic pressing process, the roundness error of the sphere is ≤± 0.05mm, the surface roughness Ra is ≤ 0.4 μ m, ensuring uniform force during precision grinding; Using 92% high-purity alumina substrate and adding 3% composite reinforcing agent, after gradient sintering at 1650 ℃, the flexural strength reaches 40MPa, and there are no cracks in the 1.5m drop ball impact, far exceeding the industry's impact resistance standard. Third party testing shows that after continuous precision grinding of electronic ceramic powder for 30 days, the wear rate is only 0.04%, and the grinding amount per unit time is 25% higher than that of ordinary grinding balls, achieving a breakthrough in both accuracy and efficiency.
