Technical Field

[0001] The utility model relates to the technical field of wire cutting machines, in particular to a wire cutting machine for processing precision castings and facilitating replacement. Background Art

[0002] A wire cutting machine mainly consists of three parts: a machine tool, a numerical control system, and a high-frequency power supply. The numerical control system is composed of a single-chip microcomputer, a keyboard, and a frequency conversion detection system, and has main functions such as gap compensation, linear interpolation, circular interpolation, and automatic wire breakage processing. It can cut materials such as high-strength, high-toughness, high-hardness, high-brittle, magnetic materials, as well as precision small and complex-shaped parts. When the wire cutting machine cuts castings, the cutting wire needs to be replaced regularly, but the replacement of the traditional cutting wire is relatively cumbersome, and the wire cutting machine is not convenient for cutting castings of different sizes.
