Description

Technical Field

[0001] The utility model relates to the technical field of graphite engraving and milling machines, in particular to an automatic tool-changing multifunctional graphite engraving and milling machine. Background Art

[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties, corrosion resistance, and is not easy to react with acids, alkalis and other agents. Natural graphite comes from graphite deposits, and can also be made into artificial graphite from petroleum coke, asphalt coke, etc. through a series of processes. Graphite burns in oxygen to produce carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It can be used as an anti-wear agent and lubricant. High-purity graphite is used as a neutron moderator in atomic reactors. It can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc. Graphite has low hardness and is very soft. Ordinary engraving and milling machines cannot be used to process graphite. Graphite engraving and milling machines are required. Ordinary graphite engraving and milling machines require manual tool change, which is not only dangerous but also inefficient. Most of the automatic tool change graphite engraving and milling machines on the market use mechanical arms to clamp the tool for engraving and milling operations. In order to prevent the tool from slipping during operation, very large pressure is often applied to the tool, which not only consumes too much electricity, but also has a certain impact on the tool, shortening its service life and even causing extrusion damage.
