Description

{The CNC precision polishing apparatus and processing method for grinding plate glass}

The present invention relates to a CNC precision polishing processing device and processing method for processing the side and surface of plate glass (or mirror). More specifically, the present invention relates to a CNC precision polishing processing device and processing method for processing the side and surface of plate glass (or mirror). It relates to a CNC precision polishing processing device and processing method capable of machining the side and plane surfaces of plate glass (or mirrors) by precisely grinding the sides or planes according to the machining drawing.

In general, plate glass is mainly produced in response to the needs of construction or furniture companies, and is used by cutting and chamfering large-sized raw glass to a certain size.

Recently, the demand for these plate glass products has been increasing by grinding the outer side or edges, so equipment for grinding the side of plate glass is being installed and used in the production line.

In addition, conventionally, manual polishing machines were mainly used as the polishing processing equipment, but this has lower workability and productivity compared to CNC equipment, as well as poor marketability due to processing quality. Recently, polishing processing of plate glass has been performed using CNC equipment. .

Meanwhile, mirrors similar to plate glass are manufactured through the same side polishing process after production as with plate glass.

However, in the case of the conventional plate glass (or mirror) described above, only the side edges are mainly polished, and in order to polish the upper surface of the plate glass (or mirror), a separate CNC equipment has to be added and used.

In other words, in the case of conventional plate glass (or mirror), it was mainly used for polishing the side edges and did not polish the upper surface. Therefore, in order to realize various commercial properties of plate glass (or mirror), plate glass (or mirror) was used. When attempting to grind the upper surface of a conventional CNC equipment that grinds the side edges, it was difficult to grind the flat surface due to differences in setting values and processing types.

For this reason, an inefficient and uneconomical problem has arisen in that separate CNC equipment is required when polishing the flat surface rather than the side edge of the plate glass (or mirror) is desired.
