Lathe or milling machine are commonly used in modern machining centers. Drilling machine, however, is a unique machine used for the removal of metal from the workpiece by means of rotating twist drill. When the drill machine is in use, it requires the workpiece to be held securely in the fixed position at its one end while the drill bit exerts pressure at the other end. Drilling machines can be found in various forms and types across many industries.
The two most common types of drilling machines are Sliding headstock and Universal arm type.
Sliding headstock drills have grown popular in various workshops, production centers, manufacturing plants and repair shops. These machines have been designed for drilling large, medium and small work pieces of simple and complex shapes. These drilling machines feature a sliding spindle assembly mounted on a robust headstock. Loads can easily travel up to 500mm for greater productivity. Some of the most common components of the hydraulic type of Sliding headstock machine include hydraulic table, hydraulic headstock and hydraulic spindle.
Universal arm type drilling machine is often used for hole making and other machining operations on heavier and larger workpieces. These machines consist of four main parts: the column, the base, the arms and the spindle. These machines are rugged and come in both manual and CNC (computer numerical control) models. The advanced Universal arm type machines possess a multi-axis design, featuring articulated arms that allow the user to create complex geometries into the workpiece. These machines are well suited for drilling, tapping, reaming, threading and other machining operations.
Regardless of the type of drilling machine being used, safety must always come first. Operators of drilling machines must ensure they are familiar with the machines safety features and its capabilities. To reduce the risk associated with using the machine, safety guards should be used to protect the operator and other workers in the vicinity of the machine. Other safety precautions include using emergency stop devices, not overloading the workpiece, and using special tapers or holders for small or lengthy workpieces.
In short, drilling machines are essential for making holes in a variety of workpiece materials. Sliding headstock and Universal arm type drilling machines can be used in a wide range of machining applications. It is important for users of the machine to be aware of the machine’s safety features and capabilities, and to follow all safety precautions when operating the machine.
