摘要： A lathe is provided with a stepless cutter feeding mechanism for cutting a workpiece at a constant linear cutting speed. The lathe includes a cutter seat that carries a cutter for cutting the workpiece and a motor for driving a main shaft that carries the workpiece. The stepless cutter feeding mechanism comprises a speed sensing device connected to the cutter for sensing linear cutting speed of the cutter. A governor device is connected to the speed sensing device and electrically connected to the motor for changing rotational speed of the motor in response to a linear cutter feeding speed of the cutter such that the cutter cuts the workpiece at a constant linear cutting speed.
