The invention discloses stainless steel tube cutting and grinding integrated processing equipment. The stainless steel tube cutting and grinding integrated processing equipment comprises a cutting mechanism, a grinding mechanism and a conveying mechanism for sequentially feeding a to-be-processed pipe to the cutting mechanism and the grinding mechanism, wherein the cutting mechanism comprises a first supporting frame fixedly arranged on a first supporting plate and a grinding wheel cutter which is arranged on the first supporting frame in an up-down moving mode; the grinding mechanism comprises a second supporting frame which is fixedly arranged on the first supporting plate and a grinding wheel grinding machine which is arranged on a second supporting frame in the up-down moving mode; theconveying mechanism comprises two rails which are fixedly arranged on the first supporting plate, and a pushing plate is arranged on the two rails in a sliding mode; and the pushing plate pushes theto-be-processed pipe to move towards the cutting mechanism. According to the stainless steel tube cutting and grinding integrated processing equipment and a processing method provided by the invention, cutting and grinding processing of a stainless steel tube can be completed once, so that midway continuous operation is avoided, and therefore, processing efficiency is greatly improved.
