Description

Technical Field

[0001] The utility model relates to the technical field of PTC, in particular to a PTC ceramic cutting device. Background Art

[0002] PTC ceramics, also known as positive temperature coefficient ceramics, are a type of electronic ceramics. They have very low resistance at room temperature. When the temperature exceeds a certain level, their resistance increases with the increase in temperature. The small-sized PTC ceramic sheets are too small to be formed, sintered, and ground by conventional processes. Currently, large-sized PTC ceramic sheets are cut into small-sized PTC ceramics. Usually, multiple large-sized PTC ceramic sheets are glued together with glue, and then the multiple PTC ceramic sheets glued with glue are glued to the tooling board with rosin, and then connected to the bracket for cutting (sometimes the bonding is not strong, and it is easy to fall off and damage the cutting blade). The small-sized PTC ceramic sheets after cutting are then chemically cleaned. The existing cutting methods are inefficient, not environmentally friendly, and costly. Utility Model Content
