Shank Adapter

Introduction

The shank adapter is a component that connects one end to the rock drill and the other end to the drill rod. Its primary function is to directly bear the impact energy and torque from the rock drill. During the drilling process, the shank adapter transfers the energy from the rock drill to the drill rod and drill bit, enabling the rock to be fractured.

The specifications of the shank adapter have a significant impact on the drilling speed, the service life of the rock drill, and the rock drilling tools. Therefore, when selecting and using shank adapters, it is important to match them properly with the specific operating conditions and the model of the rock drill.

Advantages

 

Premium Material Selection

 

Our shank adapters are made from high-quality steel, known for their high strength, toughness, wear resistance, and corrosion resistance, ensuring excellent performance even in harsh working conditions.



 

Precision Manufacturing

·We utilize advanced CNC machining equipment and processes to ensure every detail of the shank adapter is meticulously crafted.

·The end face of the shank adapter is smooth and flat, with the cross-section perpendicular to the axis. The fit gap between the shank adapter and the rock drill sleeve is controlled within 0.5mm, ensuring stability and efficiency during the drilling process.

 

 

 

Advanced Heat Treatment

 

·Our shank adapters undergo advanced heat treatment techniques to ensure they have the proper hardness and toughness after processing.

·The hardness of the shank adapter is generally controlled between HRC 38–45, ensuring a balance between durability and preventing damage to the rock drill piston.



 

Variety of Specifications

·We offer a wide range of specifications and models for our shank adapters to meet the needs of different rock drills and working environments.

·Customers can choose the appropriate shank adapter based on their specific requirements, ensuring optimal drilling efficiency and operation quality.

Factors to Consider
When Choosing Shank Adapters

 
140x140

Rock Drill Model and Specifications

· Rock Drill Model Match

The shank adapter must be chosen according to the rock drill's model and specifications to maximize the machine's performance and efficiency.

 

· Power and Torque

The power and torque of the rock drill determine the strength and size of the shank adapter required. Ensure that the selected shank can withstand the impact and torque produced by the rock drill.

 

· Interface Size

Pay attention to the connection method (e.g., threaded, quick-connect) and interface size of the shank to ensure secure and reliable connections with the rock drill and drill rod.

 

Working Environment and Operational Requirements

· Rock Hardness

Choose a shank adapter with appropriate hardness and wear resistance based on the hardness of the rock at the work site.

 

· Drilling Depth

For deep-hole operations, a higher-strength shank may be required.

 

· Working Environment

Consider environmental factors such as humidity, temperature, and corrosion when selecting a shank with the necessary protective features.

140x140
 
140x140

Water Supply Method and Structural Features

· Water Supply Method

Select the appropriate shank based on the rock drill's water supply method (e.g., central water supply, side water supply).

 

· Structural Features

Based on the structural characteristics of the shank (e.g., two-wing, three-wing, four-wing), choose the model that suits the rock drill and operational needs.
