Precise wire polishing device driven by linear motor

The utility model provides a precise wire polishing device driven by a linear motor aiming at the problem of the unstable running of a tool wire brought by the wire polishing device driven by a rotary motor in the case that a rotary motion is converted to a linear reciprocating motion. The device comprises a device base, a slide rail seat fixed on the device base, and a linear reciprocating motion mechanism movably connected with the slide rail seat, wherein a stator is fixed on the bottom of the linear reciprocating motion mechanism; a rotor is fixed in the groove of the device base right opposite to the stator; and the stator and the rotor compose the linear motor. Additionally, the device is combined with a clamp rotating mechanism, a tension adjusting mechanism, a front tool wire angle adjusting mechanism and a rear tool wire angle adjusting mechanism, thus realizing machining for the different areas of a microporous wire-drawing die; and the device is especially suitable for machining the microporous wir
