A drilling machine is a machine tool that uses a drill to make holes on a workpiece. It is usually used to make holes with smaller sizes and less precision requirements. During drilling, the workpiece is generally fixed, and the tool performs a rotational main motion while performing an axial feed motion. A drilling machine can complete drilling, reaming, boring, and tapping, and its maximum parameter is the maximum drilling diameter. The main types of drilling machines include bench drilling, vertical drilling, and radial drilling.
Vertical drilling machine
|
It is mainly composed of a spindle box 3, a feed box 4, a workbench 1, a column 5, and a base 6. During processing, the workpiece is directly or through a fixture mounted on the workbench, and the motor enables the spindle to achieve a rotational main motion through a speed change system; at the same time, the feed box enables the spindle to perform an axial feed motion with the spindle sleeve, and the workbench and the gearbox can adjust their upper and lower positions along the column to meet the requirements of processing workpieces of different heights. In addition, the operating mechanism installed in the gearbox can enable the spindle to achieve manual rapid lifting and lowering, manual feeding, and connecting and disconnecting motorized feeding.
After machining one hole on a vertical drilling machine, when machining another hole, it is necessary to move the workpiece so that the tool is aligned with the center of the machined hole, which is very inconvenient to operate. Therefore, vertical drilling machines are suitable for machining small and medium-sized parts in single-piece and small-batch production.
The variants of vertical drilling machines include multi-head vertical drilling machines, row-type multi-axis vertical drilling machines, etc. They are equivalent to the combination of several single-axis vertical drilling machines, which are used to sequentially drill holes of different diameters on the same workpiece or the same hole in sequence. Different processes such as drilling, expanding, and reaming. Since it can save time for tool replacement, it is mainly used in medium and small batch production of small workpieces.
Radial drilling machine

The radial drilling machine is a drilling machine in which the rocker arm rotates and rises around the column and the spindle box moves horizontally on the rocker arm. It is widely used in the machining of large and medium-sized parts. It is mainly composed of an inner column, an outer column, a rocker arm, a spindle box and a base. The spindle box is mounted on the rocker arm and can move horizontally along the guide rail on the rocker arm. The rocker arm is mounted on the outer column and can move up and down along the outer column to meet the requirements of processing workpieces of different heights. In addition, the rocker arm can also rotate around the inner column with the outer column within a range of 180 degrees, so the spindle can be easily adjusted to the required processing position. In order to keep the spindle in a certain position during processing, the radial drilling machine is preferably equipped with a clamping mechanism for the column, rocker arm and spindle box. When the position of the spindle is adjusted, they can be quickly clamped.
Other variations of the radial drilling machine, such as the universal radial drilling machine, the rocker arm and the spindle box can be rotated or tilted, so that the spindle can be drilled in any direction in space. This machine tool is suitable for processing large workpieces in manufacturing industries such as heavy machinery, locomotives, ships and boilers.
CNC drilling machine

CNC drilling machine is mainly used to process holes and hole systems with position accuracy requirements. It can perform drilling, expansion, reaming, tapping and other processes. The X, Y and Z axes are controlled by the CNC system and stepper motor, with large torque and high positioning accuracy. This machine tool series has good rigidity, simple programming, convenient operation and reliable use. It is suitable for all industries, especially small and medium batch and multi-variety machining.
