FRONT HEAD

780 502 71 FRONT HEAD The FRONT HEAD is a crucial part of any rock drill drifter. It forms the very front section, acting as an interface between the drifter's internal mechanisms and the drill string. Inside, it typically holds the chuck bushing, shank adapter, and various seals. Its primary job is to efficiently transfer the impact energy and rotation from the drifter's piston to the drill steel, driving the bit into the rock. It also plays a significant role in guiding the drill string and containing the flushing air or water that clears cuttings from the borehole.

Proper functioning of this component is essential for both drilling performance and overall machine reliability. A worn or damaged FRONT HEAD can lead to a significant loss of impact energy, directly reducing penetration rates and increasing drilling time. If the internal seals or bushings within the head wear out, hydraulic oil can leak, or dust and water can enter the drifter, causing premature wear to more expensive internal parts like the piston and cylinder. Excessive play in the drill string due to FRONT HEAD wear can also put undue stress on other drifter components and even lead to drill string breakage.

Regular inspection of the FRONT HEAD is important during routine maintenance. Look for any visible cracks, excessive wear on the chuck bushing area, or signs of oil leakage. Reduced drilling performance or unusual noises from the drifter's front end can also indicate a problem. Replacing a worn FRONT HEAD promptly helps maintain optimal drilling efficiency and protects the more complex internal components of your rock drill. Ensure proper lubrication and flushing system operation to extend its service life.
