The invention discloses a shock-absorption lathe turntable. The lathe turntable comprises a workbench and a rotating shaft, wherein the rotating shaft is arranged at the center of the workbench; the workbench is provided with multiple groups of combined grooves; each combined groove comprises three T-shaped grooves and a tooth-shaped groove which are sequentially arranged; the directions of the T-shaped grooves and the tooth-shaped grooves are superposed with the radial direction of the workbench; the shock-absorption lathe turntable also comprises press bolts slidably arranged on the combined grooves and multiple shock absorbers arranged at the lower part of the workbench; a scrap baffle is arranged at the periphery of the workbench. Acting forces generated by contact between a milling cutter and a workpiece can be balanced out by multiple shock absorbers, so as to ensure that a cutting procedure is stably performed on the workpiece on the workbench; sweeps which are splashed all around and are produced by processing can be shielded by the scrap baffle arranged at the periphery of the workbench, and splashed sweeps are prevented from influencing the sight lines of working personnel, so as to well ensure that the processing procedures are effectively performed.
