▎ 摘　　要

NOVELTY - The device has a pressure sensor (8) mounted under a cutter tool (9). An oil tank (2) contains lubricating oil. An end of an oil pipe (3) is connected with the oil tank. Another end of the oil pipe is connected with a guide pipe (7). The pressure sensor is connected with a controller (5) that is connected with a switch (4). The pressure sensor collects a pressure signal when the cutter tool cuts a workpiece. The controller converts a pressure signal into an electric executing signal to the switch. The guide pipe is made up of copper or stainless steel material. USE - Device for cutting a nanometer graphene workpiece. ADVANTAGE - The device has reasonable design and high radiating effect, and is convenient to use, and realizes actual work condition according to the workpiece and automatically dispenses amount of the lubricating oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for using a device for cutting a nanometer graphene workpiece. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a device for cutting a nanometer graphene workpiece.
