Diversity of bench drill types

Bench drill is a kind of small hole processing machine with delicate volume and simple operation. It is generally installed on a special workbench and used for drilling, expanding, and twisting holes below Φ12mm. It is mainly used for drilling, reaming, reaming, tapping and scraping of small and medium-sized parts in technical workshops and machine tool repair workshops. It is also one of the indispensable tools in the fitter training room.

There are many types of bench drills, including vertical drilling machines, single-spindle drilling machines, multi-spindle drilling machines, fixed drilling machines, horizontal drilling machines, radial drilling machines, mobile drilling machines, magnetic seat drilling machines, slide drilling machines, deep hole drilling machines, semi-automatic drilling machines, and CNC drilling machines. , Gantry CNC drilling machine, combination drilling machine, drilling and milling machine, etc. The more commonly used are desktop, vertical and rocker…

1. Vertical drilling machines are generally used to drill holes on medium-sized workpieces. The maximum drilling diameters are 25mm, 35mm, 40mm and 50mm. With automatic feed device, the spindle speed and automatic feed have a large adjustment range, so it can be used for drilling, expanding, countersinking, reaming and tapping different materials.

2. The bench drilling machine has simple structure and convenient operation. It is often used for drilling small workpieces and expanding holes with a diameter of less than 12mm. The bench drilling machine is mainly composed of a power system and a transmission system; the power system is provided by an electric motor to drive the pulley to rotate, and the transmission system is composed of a main motion and a feed motion.

3. Radial drilling machine: Radial drilling machine relies on moving the drilling machine spindle to align the center line of the hole on the workpiece, so it is more convenient than vertical drilling machine during processing.

The main shaft gearbox can make a wide range of movement on the rocker arm, and the rocker arm can rotate 360° around the column. Therefore, the radial drilling machine can be placed on the workbench, the base, or even placed on the ground next to the base Large and small workpieces are drilled. After the drilling machine spindle moves to the desired position,

The rocker arm can be fastened to the column, and the main shaft gearbox can also be fastened to the rocker arm. The spindle speed range and feed range of the radial drilling machine are wide, so the processing range is wide, and it can be used for drilling, reaming, countersinking, reaming, boring, tapping, and cutting large screw holes.
