Drilling coring machine has beautiful appearance, strong and durable, easy to start, reliable operation, easy to operate, equipped with the market artificial diamond thin wall drill, suitable for drilling concrete, cement, asphalt pavement, rock and other materials, and can be configured with electric ignition device.
Concrete drilling coring machine has two main purposes, one is horizontal drilling, suitable for the installation of road nails, road piles.It has been widely used in transportation engineering company, China railway group, integrated housing company and so on. Second, coring, suitable for pavement coring test, has been widely used in various testing centers.
Drilling coring machine matters needing attention
1. drilling rig, should feel little resistance, smooth cutting, drilling and the feed rate is about 4 to 5 m/min when drilling nearly finished, due to the change of cutting force, some vibration drilling, at this time due to lower feed speed, when finished cutting, should immediately improve bit fast until the blade out of work, and shutting the drill and cut off the water.
2. Sufficient water cooling must be maintained throughout the drilling process
3, drilling and drilling end of the rapid lifting of the drill bit, should not stop, but when the drill just out of work, stop the spindle rotation, then lift the drill bit.
4, drilling, if found that the drill bit stuck, should quickly raise the bit a section, but then slowly drill in, avoid hard drilling and break the bit.
5. If the temperature of the motor exceeds 70℃ during the drilling process, it shall be temporarily stopped for cooling before use.
6. Push the switch button and turn the operating handle forward to make the drill slowly contact the concrete surface. 7, if in the process of drilling, the drill bit can not drill, the surface of the diamond part is not fully exposed, the need for strong wear materials (such as firebrick, grinding wheel, etc.) to open the edge, when the surface of the drill has completely exposed the diamond, at this point with the hand mold surface layer, from rough, can be drilled.
