Disclosed are an apparatus and a method for monitoring a glass plate polishing state. The apparatus may include a location measuring unit for measuring a location on a glass plate being polished by a polishing machine, a current measuring unit for measuring an electric current flowing into the polishing machine, a memory unit for storing a reference value of the electric current flowing into the polishing machine for each polishing location of the glass plate, and a control unit for determining whether a polishing state is faulty, by comparing a value of the electric current measured by the current measuring unit for each polishing location measured by the location measuring unit with a corresponding reference value of the electric current stored in the memory unit for each polishing location.

Apparatus and method for monitoring glass plate polishing state

Disclosed is a substrate polishing method capable of minimizing a difference of polishing amounts between a center portion and a rim portion of a large scale plate during a plate polishing process.

Method for uniformly polishing large scale plate

A polishing pad of a polishing system is mountable to a polishing plate and has a predetermined channel pattern so as to allow a polishing liquid supplied from a polishing liquid supplier to move on a polishing surface. The channel pattern has at least two kinds of patterns.

Polishing pad of polishing system

A lower unit for a glass polishing system includes a support installed to a rotatable turntable, and a carrier having a supporting part for supporting a glass to be polished, and a placing part formed in a surface opposite to the supporting part and fixed and placed to the support.
