Bench drill is a small hole processing machine tool with small volume and simple operation. It is generally installed on a special worktable and is mainly used to drill, expand and twist Φ Holes less than 12mm. It is mainly used in technical workshops such as drilling, reaming, reaming, tapping and scraping of small and medium-sized parts and machine tool repair workshops. At the same time, it is also one of the essential tools in the fitter training room.
There are many kinds of bench drills, including vertical drilling machine, single axis drilling machine, multi axis drilling machine, fixed drilling machine, horizontal drilling machine, rocker drilling machine, mobile drilling machine, magnetic seat drilling machine, slide drilling machine, deep hole drilling machine, semi-automatic drilling machine, CNC drilling machine, gantry CNC drilling machine, combined drilling machine, drilling and milling machine, etc. More commonly used are desktop, vertical and rocker
1. Vertical drilling machines are generally used to drill holes on medium-sized workpieces. Their Zui large drilling diameters are 25mm, 35mm, 40mm and 50mm. With automatic feeding device, the spindle speed and automatic feeding have a large adjustment range, so it can be used for drilling, expanding, spot facing, reaming and tapping screws for different materials.
2. Bench drilling machine has simple structure and convenient operation. It is often used to drill and expand holes with diameter less than 12mm for small workpieces. Bench drilling machine is mainly composed of power system and transmission system; The power system is powered by the motor to drive the pulley to rotate. The transmission system is composed of main motion and feed motion.
3. Radial drilling machine: radial drilling machine relies on moving the spindle of the drilling machine to align with the center line of the hole on the workpiece, so it is more convenient to process than vertical drilling machine.
The spindle gearbox can move in a large range on the rocker arm, and the rocker arm can rotate 360 ° around the column. Therefore, the rocker drilling machine can drill workpieces of various sizes placed on the workbench, on the base, and even on the ground next to the base of the drilling machine. After the drilling machine spindle moves to the required position,
The rocker arm can be fastened on the column, and the spindle gearbox can also be fastened on the rocker arm. The spindle speed range and feed range of the radial drilling machine are very large, so the processing range is wide. It can be used for drilling, reaming, spot facing, reaming, boring, tapping screws, cutting large screw holes and other hole processing work.
