Precision alloy cutter with multiple functions

The utility model discloses a precision alloy cutter with multiple functions, and relates to the field of precision alloy cutters, the precision alloy cutter comprises a cutter supporting plate, in order to solve the problem that a compact alloy cutter has few functions, an air box is arranged on the cutter supporting plate, and when a cutting cutter cuts a workpiece clamped on a workpiece fixing clamp, the air box is arranged on the cutter supporting plate. The special-shaped wheel and the strong magnetic ball are fixed in an adsorption mode, the strong magnetic ball is fixed to the surface of the special-shaped wheel in an adsorption mode so as to stretch out and draw back according to the shape of the surface of the special-shaped wheel, and when the strong magnetic ball stretches out and draw back, the strong magnetic ball drives a polishing block at the end of a guide rod to stretch out and draw back through a pushing plate to conduct synchronous polishing operation on a workpiece; the air in the air box
