The difference between single column and double column of radial drilling machine

1. Structural differences

The main difference between single-column and double-column is their load-bearing structure. The single-column radial drilling machine uses a single column to support the entire rocker system, which presents a distinctly simple shape when viewed from above. The double-column radial drilling machine uses two columns to share the weight of the rocker, forming a more stable foundation.

Single-column radial drilling machine:

The structure is relatively simple and suitable for the processing of small parts.

It occupies a small area and is suitable for factories with limited space.

Although the stability is slightly inferior, it performs well in light processing.

Double-column radial drilling machine:

The structure is complex and suitable for the processing of large or heavy parts.

Stronger stability and can withstand greater cutting forces.

It occupies a large area and is suitable for large-scale machining centers with complete equipment.

2. Machining accuracy and load capacity

Radial drilling machines of different structures show obvious differences in machining accuracy and load capacity. Due to the limitations of its design, the single-column drilling machine has a relatively low load capacity and is suitable for processing light materials. The double-column drilling machine has higher stability and can ensure high precision when processing heavy and complex workpieces.

3. Comparison of application scope

The choice of radial drilling machine depends not only on the structural form, but also on the type and size of the workpiece. The following is an analysis of the application scope of the two types of drilling machines:

Single-column radial drilling machine:

Suitable for small-batch production and light parts processing.

Used for fine hole processing, reaming and other processes.

Can be used in workshops with smaller space.

Double-column radial drilling machine:

Widely used in large-scale production and heavy workpiece processing.

Suitable for various complex shapes of parts, ensuring high precision.

Mostly used in high-demand industries such as infrastructure construction and aerospace.
