The Metal needle cloth grinding machine TDM-FS with reciprocating needle cloth grinding machine is specifically designed to address the loss of sharpness in the needle tip after using The XI LIN and doff needle cloth of the carding machine. It employs uniform, constant elastic pressure throughout the process to restore the sharp angle, thereby extending the replacement period of the needle cloth and enhancing the quality of the carding cotton net. The machine allows for the adjustment of reciprocating grinding times and gravel movement speed based on the variation in needle tip loss.
