HZ-20 type concrete coring machine coring machine core drill bit wholesale price

Type concrete coring machine coring machine core drill bit wholesale price
Features of this concrete core drilling machine: no power required, drilling rig and sampling dimensions are accurate, the surface after drilling is smooth, and the drilling is accurate No accidental damage will occur when picking up items. It adopts double column structure and spiral feeding method, which has good stability and simple and labor-saving operation. Equipped with row wheels, it is easy to move. It adopts high-speed cutting technology and is matched with thin-walled diamond drill bits. It can drill high-strength reinforced concrete with high drilling efficiency, accurate hole position, smooth hole wall, good hole quality, and complete and smooth core sample. Small vibration, no damage to the building
This type of concrete drilling core machine is powered by a gasoline engine (imported original machine), easy to start, and is equipped with an artificial diamond thin-wall drill bit. Mainly used for concrete and asphalt pavement testing equipment in highways, airports, ports, dams, etc. This machine can take centimeters of depth. It can take concrete, limestone foundations, etc. on high-grade highways to conduct compression and flexural tests.

Structural composition: The main structure is a two-column vertical structure with the drilling direction vertically downward. It is mainly composed of a gasoline engine, a gearbox, a spindle, a drill bit, a column, a base lifting structure, a cooling water pump, and a traveling mechanism. The concrete core drilling machine is easy to start, reliable in operation, and easy to operate! It is widely used as an essential testing equipment for concrete and asphalt pavements such as highways, airports, ports, docks, dams, etc. It is mainly used for drilling concrete and asphalt concrete. Test the core and conduct compression and bending tests.
Operating procedures:
() Install a hollow drill bit of appropriate diameter.
() Move the drilled hole to the required working place, fix the drilled hole with expansion screws, and adjust the anchor screws to make the drill stable. Or use a base plate heavy enough to fix the drilling and coring machine to prevent the machine from moving when drilling and coring.
() Connect the water source and check whether there is water flowing out.
() Start the generator and open the circuit switch.
() Rotate the handle to lightly touch the drill bit to the area to be cut. When the drill bit has advanced approximately, pressurize the handle to speed up the advancement.
() After the cutting is completed, the drill bit can be kept rotating and raised until it is approximately 10 seconds away from the surface of the specimen. The power can be turned off, the drill bit leaves the surface of the specimen, and the water source can be turned off.
() Remove the fixing bolts, drag away from the coring machine, and use clamps to take out the sample.
() When using, the drill bit should be prevented from hitting hard objects to avoid damage to the drill bit.
Notes:
When the concrete drilling coring machine is drilling, the feed speed should be ensured to be uniform, about ~. If the drill bit is found to be stuck, the feed speed can be appropriately reduced if necessary. You can raise the drill bit by a certain amount, and then drill in slowly. Avoid drilling hard to avoid damaging the drill bit and the machine.
. Sufficient water cooling must be maintained throughout the drilling process.
During the drilling process, overloading is not allowed. When the motor temperature exceeds ℃ (it feels hot to the touch), the loading force should be reduced and a new drill bit should be replaced.
When drilling is completed, the machine can only be stopped when the drill bit is separated from the workpiece.
Maintenance and inspection of concrete drilling and coring machines:
Regularly check the joints of various components of the concrete drilling and coring machines. If there is any looseness, adjust it in time.
When installing the drill bit, lithium-based grease should be added to the two threads.
After drilling, clean all parts of the drilling rig and add lubricating oil to the column and rack.
When the concrete drilling core machine is used, replace the lithium-based grease in the reduction gearbox every six months.
