1. The double-station design is high-efficiency, the machine is small and space-saving, and the operation is flexible and convenient.

2. It is suitable for processing workpieces with different shapes, different specifications of tenon grooves and hole positions, and has strong practicability, especially for workpieces with multiple tenon grooves and small tenon groove spacing.

3. It has obvious advantages for processing the same workpiece with different tongue and groove lengths and depths or heterogeneous workpieces.
