Equipment Highlights

Equipment Highlights

(1) Unique upper plate floating fixed plate processing technology: high-precision double-sided grinding can be realized.

(2) Hydrostatic bearing support technology: to ensure extremely high bottom plate end face runout and support rigidity, to achieve high product requirements.

(3) The upper disc is equipped with a real-time online measurement system: it can detect the thickness of the ground product in real time.

(4) upper plate steel wire suspension balance structure: can realize the upper plate adaptive floating at the same time with damping function.

(5) The lower disc has high precision and high stability: the oil pressure of the outer gear ring rises and falls, and the lower disc remains fixed.

(6) Precision servo proportional valve: the upper plate is pressurized, and the pressure is accurately controllable.
