Here's a detailed outline you can follow:
1. Pre-Test Preparation
Visual inspection
Check for cracks, wear, oil leaks, loose bolts.
Inspect drill rod, bits, and couplings for damage.
Fluid levels
Hydraulic oil, lubrication oil, coolant, and fuel.
Calibration
Ensure sensors (pressure, torque, rotation speed) are correctly calibrated.
Safety check
Emergency stop switch, guards, alarms, fire extinguisher, PPE readiness.
2. No-Load Test
Purpose: Confirm that the machine runs smoothly without load.
Start engine/motor and let it run at idle, then full RPM.
Listen for abnormal noises, vibrations, or overheating.
Test all control functions (rotation, feed, swing, boom movement).
Record hydraulic pressure, oil temperature, and motor current.
3. Load Test
Purpose: Verify drilling ability under normal working resistance.
Drill into standard test material (rock, concrete block, or site-specific rock).
Measure:
Penetration rate (m/min or mm/s)
Rotation speed & torque (to check power delivery)
Feed force and stability of feed system
Energy consumption (fuel or kWh per drilled meter)
Observe:
Drill bit wear after set depth/time
Cooling/lubrication effectiveness
Dust suppression (if equipped with water or mist spray)
4. Endurance Test
Purpose: Simulate prolonged work to assess durability and overheating risk.
Run machine continuously for several hours under typical load.
Monitor:
Hydraulic oil temperature trends
Gearbox/motor temperature
Lubrication flow and consumption
Stability of penetration rate over time
5. Precision & Control Test
Purpose: Check operator control accuracy.
Drill at specific angles (vertical, inclined, horizontal) and check deviation.
Test positioning repeatability for robotic arms or feed rails.
Verify braking and stopping accuracy of rotation/feed.
6. Safety System Verification
Test emergency stop under load.
Check overload protection (torque limiters, pressure relief).
Inspect guarding and interlock function.
Simulate fault conditions to confirm alarms.
7. Documentation & Analysis
Record all measured data (pressures, temperatures, penetration rates, torque, vibration levels).
Compare against manufacturer specifications.
Identify performance loss points (e.g., slow penetration due to low torque).
Make maintenance or adjustment recommendations.
