The present invention relates to a continuous linear compression spring grinding device for grinding end surfaces of a linear compression spring (10) by means of upper and lower chain conveyors (100, 200) and grinding units (300). The continuous linear compression spring grinding device, which can easily exchange two grinding wheels mounted facing each other in parallel, is characterized by comprising: two grinding units (300) in each of which transmission to a grinding wheel (350) occurs through a gear box (260) and a rotary shaft of a motor (240) is positioned higher than a central shaft of the grinding wheel (350), and which are installed facing each other in parallel on both sides of the linear compression spring (10) fixed to the continuous linear compression spring grinding device so as to grind both end surfaces of the linear spring; two hinge shafts (140) which are fixed, on the lowermost surfaces of the grinding units (300), at positions spaced a predetermined distance from the grinding wheels, and w
