The grinding device for denture processing, by setting an adjustment and fixing mechanism, can drive the fixed clamp to slide and open by sliding the slider, place the denture body to be polished on the loading plate, and reset the slider to rebound by the reaction force of the spring to drive the fixed clamp to move and close to clamp and fix the denture body, and provide elastic contact anti-wear protection for the denture body by using a protective pad made of rubber, so as to effectively and conveniently clamp and fix the denture body of different sizes according to the needs of use, and the operation is simple and convenient, and no manual pressing and fixing is required to avoid easy harm to the staff.

[0004] However, there are still the following disadvantages: the device uses the elastic force of the spring to clamp the fixed splint on the denture, but the device has a larger clamping force on smaller dentures and a smaller clamping force on larger dentures, and cannot actively adjust the clamping force of the fixed splint on the denture when the denture is small.
