GREASE

GREASE 3217 9766 25 Proper lubrication is fundamental to the reliable operation of any underground drilling rig. Grease works by forming a protective film between moving metal surfaces, preventing direct contact and the damaging friction that comes with it. This significantly reduces heat generation and material loss, which are major contributors to component failure in high-stress environments like rock drilling. It also helps to seal out contaminants like dust, water, and rock fines, which can quickly abrade and damage internal mechanisms.

You'll find grease applied in various critical areas across the drilling machine. This includes the threads of drill rods and bits, ensuring smooth coupling and uncoupling and preventing seizing. It's also vital for components within the drifter, such as the piston and rotation unit gears, where it minimizes wear and allows for efficient power transfer. Additionally, boom pins, feed chain rollers, and other articulation points rely on consistent greasing to operate freely and without excessive play, which can impact drilling accuracy and overall machine stability.

Neglecting lubrication or using the wrong type of grease can lead to a cascade of problems. Common symptoms include increased operating temperatures, unusual noises like squealing or grinding, and a noticeable drop in drilling penetration rate. If components like drill rod threads seize, it can cause significant downtime and costly repairs. To maintain peak performance and extend equipment life, always follow the manufacturer's recommended greasing schedule and use the specified type of lubricant. Regular inspection for signs of wear or contamination during greasing is also a good practice.
