Introduction Processing ceramic materials by ordinary grinding or low speed-deep grinding have low efficiency and high cost.
The primary cutting zone, the main material removal area, bears the main cutting force, and materials in this zone broke into debris in large-scale.
Conclusions From above analysis, the following conclusions could be drawn: (1) Axial turning-grinding of ceramic materials is a practical method, which could greatly improve the efficiency of ceramic materials processing and reduce processing costs.

Because of steel tube concrete structure can give full play to the potential of steel pipe and concrete, the members capacity is increased, the component design section and the weight are reduced, materials are saved, so the structures are widely used in industrial workshop, framework, tall and super-tall buildings, etc.
Main factors influencing the concrete-filled rectangular steel tube The interaction between the steel tube and core concrete is mainly performed at the constraint function of the core concrete to the steel tube, which make the concrete material changed, strength increased, plasticity and toughness improved.
