What Is Top Hammer Drilling?
During the process of Top Hammer Drilling, the top hammer drilling rig produces a percussive force on the drill rods or tubes, which is transmitted to the drill bit. The feed device is usually attached with a hinged boom to a mobile unit. The top hammer drill machine is widely used in the mining, construction, and quarrying of rock material. As a professional hydraulic drilling rig manufacturer in China, Taiye can provide various types of the hydraulic rotary rig for top hammer drilling of hard materials.
Can You Use a Top Hammer Drill as a Regular Drill?
This top hammer drill is also called "hydraulic rotary hammer drill", which is a core bore drilling machine with a forward thrusting force. As the drill bit spins, the top hammer drilling machine rapidly vibrates front to back, allowing it to drill through hard materials such as stone, concrete, tile, or brick.
The modes of high-quality top hammer drilling rigs usually have three modes for their function. The "hammer" mode provides a straight impact force. The "drill" mode provides a rotary action as in a regular drill. The "hammer drill" mode provides a combination of both.
Generally speaking, top hammer drilling machines tend to be more expensive than regular drills. Another consideration in hammer drills is weight and size. Top hammer drilling machines tend to be heavier and bigger than regular drills and often come with a side-mounted handle to aid in their control.
A top hammer drill machine certainly can be used as a regular drill by putting it in "drill" mode, it has some limitations and a complete tool inventory should ideally include both. However, if you're only going to buy one drill, a hammer drill is the more versatile of the two.
How Does a Hydraulic Drilling Rig Machine Work?
Hydraulic rotary drilling is all about power and speed. You need a lot of power to break into solid rock and high speed to repeatedly hammer away at a work site. For safety and high productivity, many of today's hydraulic borewell machine adopts remote control.
Top hammer hydraulic rotary drilling hammers the rock with impacts transferred from the rock drill to a drill bit in the bottom of a hole. Hydraulic pressure generates the force required — pressure builds to a maximum and when released, drives an impact piston forward. When the piston strikes a chuck, it transfers its kinetic energy as a stress wave through a drill rod to the drill bit, which uses this impact energy to break the rock. The hydraulic rotary rig has the highest drilling productivity and the economy requires the operation of all components in the system to be highly synchronized.
