rotation unit, auxiliary for feed oil cylinder)
- Includes hydraulic box, filter, handle pump, oil condenser, and
electric control box
- Fast drilling speed with ability to drill holes from any angle in
work tunnel by column
- Main body consists of feed frame, rotation unit, rod holder,
column, and cylinder for easy assembly/disassembly
- Can drill holes from 0°~360° in work tunnel by column
- Simple control via operating bar - workers only need to handle rods
- Auto-feeding capability with easy control of feeding force and work
speed
- Synchronized operation of chuck and rod holder
- Easy rod fixing and loading without spanner
- Instrument boards display feed pressure, system pressure, and
flushing water pressure values
