The concrete drilling and coring machine is mainly used for drilling and coring hardened concrete such as buildings, highways, airports, wharfs and dams. It has the characteristics of simple operation, convenient relocation and accurate drilling and coring. The surface of the core sample is smooth, and there is no accidental damage to the core sample. It is an indispensable equipment for highway transportation departments, construction departments and relevant colleges and universities. The machine meets the standard of gb11818-89 technical requirements for concrete drilling and coring machine.

In addition, the drilling rig can also drill and core other non-metallic brittle and hard materials, such as refractory, ceramics, glass and rock.

Technical parameters of hz-15 concrete drilling and coring machine:

1. Maximum drilling diameter: 160mm

2. Maximum drilling depth: 400mm / 200mm 700mm

3. Input power: 2300W 3300W

4. Maximum cutting (grinding) diameter: 150mm

5. Maximum cutting (grinding) height: 150mm

6. Cutting (grinding direction): transverse

7. Saw blade (grinding head) material: artificial diamond

Application method of hz-15 concrete drilling and coring machine:

1. Move the machine to the place where drilling and coring are required, screw four adjusting screws (5) on the base, adjust the machine level, and embed M16 iron expansion bolts on the ground to fix the machine.

2. Install the drill bit according to the size requirements of the drilling hole.

3. Connect the water source and check whether there is water leakage in the drill bit.

4. Turn on the power switch, idle for several minutes, and turn the feed handle to drill.
