Description

CUTTING MACHINE AND CUTTING SYSTEM

The present invention relates to a cutter and a cutting system, and more particularly, to provide a cutter and a cutting system capable of precisely cutting a product under a single process.

In a typical cutter and cutting system, the product is cut using a cylinder. However, when cutting the product using a cutter and a cutting system using a conventional cylinder there was a disadvantage that the product is not precisely cut.

For example, the conventional black and white cell phone light guide plate does not have a big problem even if the above cutter and cutting system are used, but the conventional cutting machine and the cutting system is not appropriate in a product that requires precise cutting, such as a light guide plate for color mobile phones.

Therefore, in order to precisely cut the product, there was a need to post-process the product cut by a conventional cutter and a cutting system through another mechanism.

The present invention has been proposed in view of the above problems, and an object of the present invention is to provide a cutter and a cutting system capable of precisely cutting a product under a single process.
