Introduce:

The concrete core drilling machine is mainly used for the compressive and flexural tests of cement, concrete, asphalt, concrete and limestone foundations such as highways, airports, ports, wharfs, dams, etc. The maximum core sample can reach 700mm.
The concrete coring machine adopts a multi-purpose machine (optional), which can drill the core, cut the core sample, and grind the core sample, which greatly improves the work efficiency and reduces the equipment investment. It is an ideal engineering testing equipment.

Notice:

1. When the concrete drilling coring machine is drilling, the feeding speed should be uniform, about 3-5cm/min. If the drill bit is found to be stuck, the feeding speed can be appropriately reduced, and the drill bit can be raised a section if necessary. , and then slowly drill in, avoid hard drilling, so as not to damage the drill bit and the machine.
2. Adequate water cooling must be maintained throughout the drilling process.
3. During the drilling process, do not overload. When the temperature of the motor exceeds 70°C (it feels hot to the hand), the loading force should be reduced and a new drill bit should be replaced.
4. At the end of drilling, the machine can be stopped only when the drill is separated from the workpiece.
