The invention discloses an anti-vibration grinding machine base structure, and belongs to the technical field of grinding machines. An anti-vibration grinding machine base structure comprises a supporting base, a control table is connected to one side of the upper end of the supporting base, and through cooperation of a third circular guide rod in a tail fixing assembly and a fourth reset spring, when grinding force is increased instantaneously, through axial sliding of a third sliding block and deformation of the spring, the grinding force can be adjusted; the transverse moving assembly and the vertical moving assembly both adopt the double-elasticity design of a reset spring and a third reset spring, high-frequency vibration generated by high-speed rotation of the grinding wheel and low-frequency impact caused by cutting force fluctuation can drive a second sliding block to slightly move along a circular guide rod through a rectangular moving block, and therefore the grinding wheel is driven to rotate in the axial direction. The springs are alternately compressed and stretched, vibration energy is dissipated through internal friction, meanwhile, a fifth reset spring of the fixing assembly is matched with elastic attachment of a semi-arc fixing block, local micro vibration of the workpiece can be absorbed, and multi-stage attenuation of radial vibration is achieved.

This invention relates to an ultra-low temperature ceramic binder, which is mainly composed of the following raw materials in the indicated mass percentages: Bi₂O₃: 40-80%, B₂O₃: 5-15%, ZnO: 10-35%, SiO₂: 0-5%, Li₂O: 0.5-3%, TiO₂: 0-5%, CaF₂: 2-10%, Y₂O₃: 0-5%. This binder can be fired at a minimum temperature of 400°C and softened at a minimum temperature of 320°C. It enables the ceramic binder to achieve bonding and consolidation before the polymeric pore-forming agent and temporary polymeric binder burn off, maintaining the integrity of the pore structure while achieving a high porosity. Furthermore, using this ceramic binder and a preferred polymeric pore-forming material, it is possible to construct spherical pores with interconnected microscopic gaps, and the pore size can be controlled during preparation.
