The slotting machine is used for slotting planes, forming surfaces, key grooves and the like, can be used for inserting working objects such as molds with inclination within the range of 10 degrees, and is suitable for enterprises with single or small-batch production.
However, the tool rest of the conventional slotting machine is not provided with a tool lifting mechanism, and the worktable is also not provided with a tool relieving mechanism, so that the slotting tool generates friction with a workpiece during return stroke, and the work adjustment is poor. In addition, for the through groove, even if the cutter is changed to enable the cutter to be provided with upper and lower side edges, the lower edge is utilized during downward slotting, and during upward slotting, the cutter firstly penetrates through a hole and then cuts upward; however, in the case of the blind slot, even if the type is changed, the cutting utilization of the idle stroke cannot be realized, and as in the case of the slotting, the idle stroke loss exists during the slotting, so that the slotting efficiency is low, and the slotting can be only used for enterprises which produce single or small batches.
