The Spindle Rotary Core Drill integrates the advantages of spindle type drilling rigs. It can be used in metal or nonmetal solid deposit exploitation. The Spindle Rotary Core Drill plays an unreplaceable role in the fields of geology, hydrology, metallurgy and coal field exploration. It has water brake and has a normally-open type clutch mechanism.
Features and Advantages
1. This Spindle Rotary Core Drill is equipped with conventional type rotary unit. It is suitable for small-diameter hole drilling with diamond bits and large hole drilling with diamond bits.
2. It is capable of drilling both vertical holes and inclined holes.
3. The chucks of this Spindle Rotary Core Drill have large clamping force and the clips have long service life.
4. One control handle can realize the conversions among eight forward and reverse speeds in one revolution.
5. The water brake used in the core drilling machine helps to reduce the operator’s workload.
6. Duplicate gear oil pump can reduce oil temperature with rational power utilization.
7. The oil-dip type clutch can be started smoothly. It has brake gear.
8. The sliding wheel of the winch is well sealed. The winch has great hoisting capacity.
9. The entire core drilling machine is very stable and easy to disassemble.
10. This Spindle Rotary Core Drill has absorbed the advantages of similar rigs at home and abroad. It features high strength, compact structure, rational layout, stable operation and centralized control.
11. It has a complete range of rotating speed.
Use and Maintenance
Clients should do some inspections before starting up the core drilling machine.
1. Connections of all components should be firm and reliable. The mating face should be clean.
2. Clients should add lubrication oil to lubrication points and check the liquid level in the oil box.
3. All braking parts of the Spindle Rotary Core Drill should be working reliably.
4. The clutch should be adjusted to a suitable state.
5. Clients can use turning gear to observe the parts and to find out whether they are moving correctly and reliably.
Clients should maintain the core drilling machine regularly.
1. Workers should check every fastening part and clean all mating faces in each shift. The Spindle Rotary Core Drill should be lubricated according to the lubrication form.
2. Clutch and hand-operated oil pump should be checked every week.
3. Clients should clean the oil box and filter the oil every month. Hydraulic oil should also be checked. Please consult the manual of the core drilling machine for detailed information.
