YH2M16B high precision vertical double side lapping (polishing) machine

Applicable occasions: high precision double-sided grinding and polishing.


Precision grinding, intelligent manufacturing technology, integrated solutions


Typical Machining Parts

Typical Machining Parts

Sapphire Silicon Carbide Ceramics


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.
