Precision wire polishing device driven by linear motor and machining method of device

The invention provides a precision wire polishing device driven by a linear motor and a method for machining a micropore wire drawing die by the aid of the device. The precision wire polishing device and the method aim to solve the problem that tool wires run unstably when rotation of a wire polishing device driven by a rotary motor in the prior art is converted into linear reciprocation. The device comprises a device base, a slide rail support and a linear reciprocating mechanism, the slide rail support is fixed onto the device base, the linear reciprocating mechanism is movably connected with the slide rail support, a stator is fixed to the bottom of the linear reciprocating mechanism, a runner is opposite to the stator and is fixed to a groove of the device base, and the stator and the runner form the linear motor. In addition, the device is combined with a fixture rotating mechanism, a tension adjusting mechanism, a front tool wire angle adjusting mechanism and a rear tool wire angle adjusting mechanism,
