1. Precision machining: The vertical slotting machine has high cutting accuracy, and the accuracy from the tip of the tool to the table surface can reach within 0.02mm.

2. Energy saving: Since the tool holder of the vertical slotting machine moves back and forth during planing, and the weight is light, the energy loss is low, which has the advantages of energy saving and environmental protection.

3. Suitable for processing large workpieces: Horizontal slotting machines usually have a large workbench, which is convenient for placing and fixing large workpieces.
