CNC vertical lathe is a common metal processing equipment. To distinguish between single column and double column, we can start from the following aspects.

First of all, from a structural point of view, there are significant differences between single-column and double-column vertical car structures. A single-column CNC vertical lathe has only one supporting column, while a double-column CNC vertical lathe has two supporting columns. These two columns will support the spindle box and tool holder respectively. Therefore, the stability of the double-column CNC vertical lathe is higher than that of the single-column.

From the perspective of processing range, double-column CNC vertical lathes are often more suitable for processing large and heavyweight workpieces than single-column CNC vertical lathes. The double-column CNC vertical lathe can withstand greater cutting forces due to its larger support area. Since the single-column CNC vertical lathe has only one supporting column, the processing weight cannot be too large, otherwise the processing accuracy will be affected.

From the perspective of production cost, single-column CNC vertical lathes are cheaper than double-column CNC vertical lathes. Because a single-column CNC vertical lathe only requires one supporting column, the production cost is relatively low. The production cost of the double-column CNC vertical lathe is relatively higher because it requires two supporting columns.

In addition, from the perspective of accuracy and stability, double-column CNC vertical lathes are often better than single-column CNC vertical lathes. Since the support area of the double-column CNC vertical lathe is larger, its processing accuracy is relatively higher. At the same time, when the cutting weight is heavy, the double-column CNC vertical lathe has better stability and will not produce excessive vibration.

In summary, the differences between single-column CNC vertical lathes and double-column CNC vertical lathes are mainly reflected in aspects such as structure, processing range, production cost, accuracy and stability. Users can choose the CNC vertical lathe that suits them according to their own needs and actual conditions.
