Product Advantages
High Drilling Efficiency
In medium-hard rock formations, a single unit can achieve a drilling speed of 300–500 mm/min. When utilized with the air pressure regulation device, the impact energy can be flexibly adjusted according to rock hardness, thereby effectively reducing operational time.
Dust Suppression and Environmental Protection
Featuring an integrated air-water linkage system the unit automatically injects water to the bottom of the borehole during drilling. This helps to suppress dust generation. It also improves the working environment, within mines. The air-water linkage system makes drilling cleaner.
Flexible and Agile Operation
Equipped with a rapid leg retraction mechanism, the unit facilitates quick movement and repositioning within narrow tunnels and roadways, thereby enhancing turnaround efficiency during multi-hole drilling operations.
Convenient Maintenance
The YT28 pneumatic rock drill employs a modular design wherein individual components can be independently disassembled and reassembled. Routine maintenance requires no specialized tools, ensuring minimal downtime for on-site repairs.
Manufacturing Process
Blank Forming: Key components are produced using precision casting or forging processes, maintaining a consistent blank acceptance rate of over 98%.
Precision Machining: Core components are processed using CNC equipment, with fitting tolerances controlled to within 0.01 mm to ensure complete component interchangeability.
Heat Treatment: Wear-prone components-such as the piston-undergo specialized heat treatment processes; this results in a surface hardness exceeding HRC55 and significantly enhances wear resistance.
