How to Operate Road Core Drilling Machine

1. Install an appropriate asphalt drill bit.
2. Move the drill machine to the work place. Fix the drill hole with expansion screws, and adjust the anchor screws, so as to make the drill rig stable. Or you can fix the core drilling machine with a sufficiently heavy baseplate, in order to prevent it from moving.
3. Connect the water source,and check if water is flowing out.
4. Start the generator and turn on the circuit switch.
5. Rotate the handle, drill bit touches the road and drills coring. When the depth is about 10mm, the handle can be pressurized to speed up the rotation.
6. After coring, you can keep rotating and raise the drill bit. When it is about 5mm away from the road surface, you can turn off the power.
7. Remove the fixing bolts, and remove the drilling sample with clamps.

Note:

1. When the concrete core drilling machine is drilling, the feed speed should be uniform, about 3 ~ 5cm/min. If the drill bit is stuck, operator should reduce speed appropriately. It is need to raise drill bit if necessary , and then drill slowly, so as not to damage the drill and machine.
2. During the drilling process, when the motor temperature exceeds 70 ℃, reduce the loading force and replace a new drill bit.
3. Prevent the drill from hitting hard objects,and avoid damaging the drill bit.

Concrete core drill for sale can drill concrete, cement, asphalt pavement and other substances. It has widely applied for drilling and coring in the fields of engineering construction, equipment installation engineering and building quality inspection. The thin-walled diamond core bit can directly drill concrete and asphalt pavement, and engineer can test the core sample. This method is widely recognized as a relatively reliable method for detecting concrete road.

Apart from cement core drill, YG machinery also includes rock drill rig, crawler core drilling rig. Rock drilling equipment is a high efficiency borehole drilling equipment. it has a wide range for drilling hole, broke concrete or cement, dismantling walls. Rock drilling tools are ideal for mining, energy exploration, road construction and other blasting engineering. Core drilling rigs can explore of metal and non-metal solid minerals. In addition, they also apply for oil and gas field surveys, and water well drilling.
