6 FAQs about [Structural principle diagram of hydraulic rock drill]

What is hydraulic rock drilling?

This reliable technology, which was introduced in the 1970s, employs hydraulic power, independent rotation, and separate flushing systems to drill through hard rock formations. Hydraulic rock drilling delivers superior accuracy, automation, and efficiency, making it fundamental to the operations of drill rig manufacturers worldwide.

How does a hydraulic rock drill work?

Hydraulic rock drills, on the other hand, use hydraulic force to generate the reciprocating motion. They rely on hydraulic cylinders to move the piston back and forth, similar to the compressed air-type drills. However, instead of using compressed air, hydraulic fluid is used to create the necessary force.

How does good drilling work?

Good drilling means that the entire system, from rock drill to drill steel to the rock itself, must harmonise. Here’s how it works. Percussive drilling breaks the rock by hammering impacts transferred from the rock drill to the drill bit at the bottom of the hole.

Why should you use hydraulic rock drills?

Versatility: Adaptable to various rock types and geological conditions, enhancing flexibility for different excavation tasks. The industry’s current trends prioritize enhancing drilling speed, efficiency, and tooling for larger hole sizes, all while increasing the power of hydraulic rock drills.

How does percussive drilling work?

Here’s how it works. Percussive drilling breaks the rock by hammering impacts transferred from the rock drill to the drill bit at the bottom of the hole. The purpose of the feed force is to keep the drill bit in close contact against the rock. The engineering challenge is to combine high feed force with good rotation.

What is a rock drill?

Rock drilling is a common practice in various industries such as mining, construction, and geology. It involves breaking through solid rock surfaces to create tunnels, boreholes, or extract valuable minerals. To accomplish this task, a powerful tool known as a rock drill is utilized.
