The invention relates to a device for pre-milling before a metallic phase of metal is observed and a stress test sample is polished, in particular to a linear reciprocating type pre-milling machine which comprises a milling platform, a reciprocating link mechanism, a motor and a supporting base, wherein the milling platform comprises a linear guide rail, a plane milling plate and a sand paper fixing clamp; the reciprocating link mechanism comprises a cam and a connecting rod; a small-size alternated current motor with a speed-regulating device is served as the motor; a frame type simple supporting base is served as the supporting base; and a speed-regulating switch is placed on one side of the supporting base. The linear reciprocating type pre-milling machine can be used for keeping straight and homonymous scratches of a metal test piece all the time during a milling process and increasing the milling precision; the milling reciprocating speed can be adjusted according to the requirement during the milling pr
