High Precision Geological Drilling Rig Machine For Core Sampling
Product Description:
1. Compact mechanical transmission structure, lightweight, vertical spindle for large through hole diameter with hexagonal drive drilling rod, ensured torque transmission.
2. Higher rotating speed and rational scope, adaptable for the drillings with small diameter diamond drill bit or large diameter carbide drill bit and other engineering hole drillings.
3. During the hydraulic controlled feeding process, both the pressure and speed of feeding can be regulated to meet the requirements of different stratum drillings.
4. Less and centralized handles, easy operation.
