The molecular structure of epoxy resin is characterized by the presence of active epoxy groups in the molecular chain. The epoxy groups can be located at the end, middle or ring structure of the molecular chain. They can cross-link with various types of curing agents to form insoluble, non-fusible polymers with three-dimensional network structure, with specification thickness of 0.5 to 100 mm, and are subject to thermal deformation at high temperature of 180 ℃. Generally, they are not heated together with other metals, which may cause metal sheet deformation.Detail
The precision required for grinding cylindrical rollers is usually higher, and the basic flatness is within 0.005. Cylindrical rollers are usually matched with high-precision bearing rings. Many P4 bearings are processed by this high-precision double-end grinder, which greatly improves the precision space.
