Is it better to buy a single-column or a double-column radial drilling machine?

The radial drilling machine moves, the spindle of the radial drilling machine rotates, that is, the cutting movement is its main movement. The longitudinal feed of the spindle is used as the feed movement. The auxiliary movement includes the vertical movement of the rocker arm on the outer column, which is simply the lifting and lowering movement of the rocker arm. The outer column and the rocker arm rotate around the inner column together, and the spindle box moves along the length of the rocker arm. The rocker arm is lifted and lowered on the column, and the clamping and loosening of the rocker arm are automatically completed according to the hydraulic push tensioning mechanism.

The transmission structure of the radial drilling machine generally adopts the method of multiple motors. Generally, there are main motors, motors for rocker arm lifting, cooling pump motors, and hydraulic pump motors.

The radial drilling machine is divided into single-column and double-column, which makes customers not know which one to choose. Is it better to buy a single-column or double-column radial drilling machine?

First of all, it should be clear that the radial drill, whether it is a single-column or double-column, has the same function and quality. The difference lies in the processing method and working materials. There is no good or bad difference. Both types of radial drills can be used to complete tapping, drilling, reaming and other tasks. The only difference is the number of layers of the column. Which radial drilling machine is good? The column of the single-column radial drill is single-layer, and the column of the double-column radial drill is double-layer.

Specifically, the single-column radial drill only needs one column, and when the rocker rolls, it will not directly conflict with the column, so it will be more laborious when rolling. The double-column radial drill is composed of two inner and outer columns. There are bearings between the inner and outer columns, and there are keyways on the outer column and the rocker arm, which greatly reduces the conflict with the column and is less laborious when rolling. Therefore, the double-column hydraulic radial drilling machine can not only increase the service life of the column but also reduce the time of rolling the rocker arm, which is very helpful to improve the working efficiency. As for whether to choose a single column or a double column, it should be determined according to the actual processing situation.
