Drilling machines are mainly machine tools that use drill bits to process holes (such as drilling, reaming, reaming, tapping, countersinking, etc.) on the workpiece. Indispensable equipment for machine building and various repair plants. It is mainly divided into the following categories according to the purpose and structure
Vertical
The table and headstock can be moved vertically on the column and are used for machining small and medium-sized workpieces.
Desktop
Abbreviated as a bench drill. A small vertical drilling machine, the maximum drilling diameter is 12~15 mm, installed on the fitter table for use, mostly manual drilling, commonly used to process small holes of small workpieces.
Rocker type
The headstock can move on the rocker arm, the rocker arm can rotate and lift, and the workpiece is fixed, which is suitable for processing large, heavy and porous workpieces, and is widely used in machinery manufacturing.
Deep hole drilling machine
In order to facilitate chip removal and avoid the machine tool being too tall, specialized machine tools that drill holes with a depth much larger than the diameter (such as deep holes in parts such as gun barrels, gun barrels, and machine tool spindles) with deep hole drilling, are generally equipped with a coolant delivery device (from the inside of the tool to the cutting part) and a periodic retract chip removal device.
Center hole drilling machine
It is used for machining the center hole at both ends of the shaft part.
Milling and drilling machines
The table can be moved longitudinally and horizontally, and the drill shaft is arranged vertically, and it is a drilling machine that can perform milling.
Horizontal drilling machine
A drilling machine with the spindle horizontally arranged and the headstock can be moved vertically. Generally, the processing efficiency is higher than that of vertical drilling machine, and it can be processed on multiple sides at the same time.
