Precautions for the use of concrete core drilling machine

The concrete core drilling machine is a kind of project machine, the earthwork engineering, the stonework engineering, the mobile crane loading and unloading engineering and various construction projects, the comprehensive mechanized construction and the mechanical homework of the manufacturing process related to the above-mentioned engineering. The necessary mechanical equipment is called engineering machinery, and the drilling machine is one of them.

Concrete core drilling machine is the primary component of construction machinery. It is established with transportation (roads, railways, ports, airports, pipelines, etc.), energy producers create and manufacture (coal, kerosene, thermal power, hydropower, nuclear power, etc.), raw material industry construction and production (black mine, colored Mines, building materials mines, chemical raw materials mines, etc., agriculture and forestry water conservancy creation (farm soil improvement, rural road construction, farmland water conservancy, rural erection and reform, forest road construction and escort, storage yard construction, breeding, harvesting, roots And the collection of branches, the creation and protection of river dams, the hustle and bustle of rivers and rivers, the dredging of rivers, the prevention of floods, etc.), the construction of industrial and civilian use (all kinds of financial construction, civil construction, urban erection and reform, situation maintenance projects, etc.) and national defense projects. The development of the creation of the categories is the same, and it is closer and closer to the establishment of the ancientization in these fields. In other words, the above fields are the primary market for project machinery.

      However, for the use of concrete core drilling machine, many customers should not understand it. Therefore, Hebei Dahong Experimental Instrument Co., Ltd. introduces the use of concrete drilling core machine :

1. When drilling the rig, the resistance should be small, the cutting is stable, and the feed speed during drilling is about 4-5m/min. When the drilling is nearing completion, the drilling will be vibrated due to the change of cutting force. Reduce the feed rate. When the cutting is completed, the drill should be lifted quickly until the cutting edge is out of service, and the drill is turned off and the water source is shut off.

2, the entire drilling process must maintain adequate water cooling

3. When the drill bit is drilled and the drill bit is quickly lifted, the machine should not stop. Instead, when the drill bit is just off work, stop the spindle rotation and lift the drill bit.

4. When drilling, if it is found that the drill bit is stuck, the drill bit should be quickly lifted for a while, then slowly drilled in, and hard drills should be avoided to damage the drill bit.

5. If the motor temperature exceeds 70 °C during the drilling process, it should be temporarily stopped and used after cooling.

6. Turn the switch knob and turn the operation handle forward to make the drill bit slowly contact the concrete surface. After the drill blade is inserted into the groove, the drill can be pressurized.

7. If the drill bit cannot be drilled during the drilling process, the diamond part of the drill bit surface is not completely exposed. It is necessary to use a strong wear material (such as refractory brick, grinding wheel, etc.) to open the edge. When the drill bit surface is completely exposed, the diamond is completely exposed. The surface layer of the hand mold is roughened before it can be drilled.

The above is a description of the precautions for the use of the concrete core drilling machine . I hope to help you. For more information, please let us know!
