Each set of rocker arm includes upper rocker, lower rocker, a center shaft, a bearing seat and a bearing, mainly to transfer hydraulic pressure to the grinding roller, and turn it into the grinding force to material bed.
1. Level-2 flaw detection standards, to ensure quality.
2. Use arc gouging and shot blasting treatment, to grantee the appearance quality.
3. Use ZG270-500, ZG30SiMnMo high-quality steel material to ensure the strong wear resistance and fracture resistance of the rocker arm.
4. Quality assurance: The fabrication route is governed by the provisions of the implemented Quality System ISO 9001:2015.
The standard documentation ensures the full traceability of every process step, including heat treatment, chemical composition test, mechanical properties test, non-destructive test, and dimensional check.
