The utility model relates to a grinding machine. The grinding machine comprises a base, a support, a motor and grinding wheel pieces, wherein the motor is arranged on the top of the support, and the grinding wheel pieces are installed at the two ends of the motor. Fixed protection covers are arranged outside the grinding wheel pieces. Fixing supports are arranged at the positions, close to the lower portions of the grinding wheel pieces, of the two sides of a stand column. Each fixing support includes an L-shaped fixing piece, wherein the vertical part of the fixing piece is provided with an open groove, and the tail end of the horizontal part of the fixing piece is provided with a cylindrical hollow column which internally provided with a fixing platform. Each fixing platform includes a cylindrical supporting rod of which the upper portion is a horizontal table. Each supporting rod is provided with a plurality of threaded holes. According to the grinding machine, the fixing supports are used for fixing an article to be ground, the horizontal distance between each fixing support and the stand column is adjusted through the vertical part of the L-shaped fixing piece of the corresponding fixing support, and the vertical distance is adjusted through the horizontal parts of the L-shaped fixing piece; in this way, the distance between articles of different sizes and shapes and the grinding wheel pieces in the grinding process is convenient to adjust, and the grinding machine has the advantage that fixation is convenient.
