Pre-sintered zirconia is preferred as a restoration material in dental applications due to its excellent strength and fracture toughness. When abrasive processes were used to obtain the required shape of (Y-TZP) yttria-stabilized tetragonal pre-sintered zirconia, it resulted in material strength degradation in the presence of coolant. Therefore, experiments were carried out on pre-sintered zirconia with diamond grinding wheel to evaluate the performance of cooling conditions such as dry, wet and minimum quantity lubrication (MQL). The effects of different environments on the grinding performance were studied based on the temperature distribution, phase transformation, flexural strength, microhardness and edge chipping damage. The Raman spectroscopy and X-ray diffraction analysis were used to estimate the quantity of monoclinic phase in pre-sintered zirconia. The temperature rise of the workpiece material during the grinding experiment was not higher and insufficient to cause the thermal stresses. The microstructural changes induced by grinding under different cooling strategies were associated with the quantitative assessment of monoclinic phase. The flexural strength of ground components was improved in the dry condition compared to the other process due to the absence of the defective layer and the occurrence of Y³⁺ ions segregation. After grinding, there was a slight decrease in the hardness value by (1–8 HV), which was due to the formation of microcracks in the subsurface layer of the ground surface. In addition, to ensure the presence of microcracks, the edge chipping depth was measured. The damage depth obtained from the wet condition showed a higher value of 30 µm compared to the dry and MQL conditions.

预烧结氧化锆由于其优异的强度和断裂韧性而在牙科应用中被优选作为修复材料。当使用研磨工艺获得所需形状的（Y-TZP）氧化钇稳定的四方预烧结氧化锆时，在存在冷却剂的情况下，材料强度会下降。因此，使用金刚石砂轮在预烧结氧化锆上进行了实验，以评估冷却条件（例如干，湿和最小量润滑（MQL））的性能。根据温度分布，相变，抗弯强度，显微硬度和刃口崩裂损伤，研究了不同环境对磨削性能的影响。拉曼光谱和X射线衍射分析被用来估计预烧结氧化锆中单斜晶相的数量。磨削实验中工件材料的温升不高且不足以引起热应力。在不同的冷却策略下磨削引起的微观结构变化与单斜晶相的定量评估有关。由于没有缺陷层和出现Y，与其他方法相比，在干燥条件下研磨组分的抗弯强度得到了改善 在不同的冷却策略下磨削引起的微观结构变化与单斜晶相的定量评估有关。由于没有缺陷层和出现Y，与其他方法相比，在干燥条件下研磨组分的抗弯强度得到了改善 在不同的冷却策略下磨削引起的微观结构变化与单斜晶相的定量评估有关。由于没有缺陷层和出现Y，与其他方法相比，在干燥条件下研磨组分的抗弯强度得到了改善³⁺离子偏析。研磨后，硬度值略微降低了（1–8 HV），这是由于在地面的表层下形成了微裂纹。另外，为了确保存在微裂纹，测量了边缘碎裂深度。与干燥和MQL条件相比，在潮湿条件下获得的损伤深度显示出更高的30 µm值。
