Principle diagram of rock drilling machine

A cutting process that involves spinning a drill bit to create a circular hole in solid materials is known as drilling. The drill bit is typically a multi-point rotary cutting tool. The bit is pressed against the workpiece and rotated at speeds between several hundred and several thousand revolutions per minute. This. . A high-precision hole-finishing procedure carried out with a multi-edge tool is known as reaming. High penetration rates and shallow cuts involved in the reaming process enable close. . A cutting process that entails enlarging an existing hole in a workpiece with a single-point cutting tool or boring head is known as boring.. . The process of enlarging one end of the hole giving it a conical shape is called countersinking. Countersinking creates a V-shaped edge near the hole's surface. It is frequently employed for deburring drilled or tapped holes, and to ensure fasteners sit tightly in the. . The process of enlarging a hole over a particular section in the workpiece for screw clearance using counterboring tools is known as counterboring. This creates a shallow and enlarged. [pdf]

Water leakage from the rock drill s rotating sleeve

(2) Elimination measures: First, adjust the pipeline to eliminate air leakage, increase the diameter of the air supply pipe, and reduce the gas consumption equipment; and whether the reversing valve is lost, damaged or stuck; the third is to add oil to the lubricator, replace the polluted lubricating oil, clean or blow through the small holes of the oil circuit; the fourth is to replace the broken water needle and replace the brazing rod that blocked the center hole The fifth is to knock off the condensed ice cubes; the sixth is to replace the worn parts in time; the seventh is to reduce the water pressure and overhaul the water injection system.
