concrete drill machine, Can drilling core and core sample cutting,can be smooth,greatly improving the work efficiency - details see: https://www.machineto.com/multifunctional-concrete-core-drilling-machine-road-drilling-machine-concrete-drill-machine-10125000

First, the product uses

APEX-LJ9512 Concrete drill machine is mainly used for buildings, roads, airports, docks, dams and other hardened concrete coring, simple operation, easy transfer machines, coring accurate, smooth surface core samples, and the core kind of accident damage, is indispensable equipment for the road transport sector, the construction sector and related tertiary institutions. This unit conforms to GB11818-89 concrete coring machine technical requirements of the standard.

In addition, the rig may be of other non-metallic brittle materials, such as refractory materials, ceramics, glass, rock also can be coring.

Third, the structural principle
APEX-LJ9512 Concrete drill machine is mainly the following components (see figure):
1, the rack : its uprights are equipped with rack, equipped with four adjusting screws in its base.
2.Slide : Set in the column, the internal gear and column rack gear pair, turning the feed handle, the slide moves up and down along the column.
3, the gear box: fixed in the sliding seat, the spindle is mounted on the drill , the feed movement with the carriage, so as to achieve the purpose of drilling.

The use of methods
1, the machine is moved to the required coring at the four screw on the adjusting screw to adjust the level of the machine on the base, and the M16 iron expansion bolts embedded in the ground, to secure the machine.
2, according to the dimensional requirements of the drill mounted on the drill bit.
3, connected to water, water leakage inspection drill.
4, turn the power switch to idle for a few minutes, and turn the feed handle, drilling.

V. Notes
1, drilling, to ensure uniform feed rate about 3 to 5cm/min about, such as bit by the card may be appropriate to reduce the feed rate, the necessary drill upgrade for a period, and then slowly drill into Avoid hard drilling, avoid to damage the drill bit and machinery.
2, the entire drilling process must maintain adequate water cooling.
3, the end of the drill, only the drill bit from the workpiece in order to shut down.
4, the drilling process, do not overload the motor temperature rises over 70 ° C (feel hot to the touch), should reduce the loading force and replaced with new drill.

Sixth, maintenance and inspection

1,Regularly check each component connections, if loose should be timely adjusted.
2, the drill bit is loaded, it should be added at the two threaded calcium-based grease.
3, after the end of the drilling, rig cleaned, and add oil column and rack.
4 every six months for a gear box grease.
