The invention relates to a honing machine tool, in particular to a reciprocating follow-up control linear motor driving device for a main shaft of a honing machine. The driving device comprises a machine tool body, a honing machine main shaft system arranged on the machine tool body, a hydraulic reversing driving system and a control system, and is characterized in that: the hydraulic reversing driving system of the honing machine comprises a main shaft hydraulic cylinder and a mechanical hydraulic servo valve for controlling the main shaft hydraulic cylinder to do reciprocating motion; a valve body in the mechanical hydraulic servo valve is connected with a movable piece in the main shaft hydraulic cylinder; a valve core in the mechanical hydraulic servo valve is connected with a switching mechanism through a connecting piece; the switching mechanism consists of a linear motor arranged on the machine tool body; one end of the connecting piece is connected with the valve core in the mechanical hydraulic servo valve, and the other end of the connecting piece is connected with a linear movable piece in the linear motor; and the linear motor is used for controlling the switching mechanism through the control system. The reciprocating follow-up control device for the main shaft of the honing machine has a simple structure and low prices, is reliably controlled and is convenient toadjust, operate and maintain.
