Diamond Core Drilling Machine Operating Procedures:

  1. The drilling machine is fixed.
  2. Install the drill bit, connect the power supply, remove the sundries, turn on the power supply, start the drilling machine with no load, check whether the drill bit is beating normally, whether the sound is stable, if it is normal, open the water nozzle, when the water flows out from the drill bit, it is possible to drill in, and it is slow to start drilling. After the drill bit is drilled into the working surface, normal pressure can be applied.
  3. When drilling thick steel bars or sections, you can feel the working state of the rig change. At this time, the drilling pressure should be appropriately reduced. When the concrete quality is not high, the stones or steel heads will fall, causing the drilling machine to generate strong vibration. If stuck in the drilling phenomenon, at this time should exit the drill bit and stop, after drilling the drill bit, the drill, can not force the drill.
  4. When the drill bit is drilled through the working surface, the drilling speed should be slow to prevent the core from being stuck in the drill bit. The drill bit should be removed to wash the inner cavity of the drill bit with tap water, then tap the drill bit wall with a wooden stick, and carefully remove the rock. Core. Do not hit the wall with a hard object such as iron to prevent damage to the drill bit.
  5. When the drill bit is stuck and cannot be withdrawn, it is recommended to cut off the power supply first, then use the wrench to clamp the drill bit to make it slowly rotate back and forth until the drill bit is loose, and then gradually withdraw from the drill bit.
  6. During the entire drilling process, the pressure should be appropriate. If the pressure is too high, the resistance will increase and the rig will be damaged. When there is a hole in the wall, you must drill slowly and the pressure should not be too long. Protective measures should be taken downstairs when drilling through the floor to prevent the core from falling off and hurting people.
  7. When drilling, it is required to have a sufficient water supply, otherwise, the life of the drill bit will be reduced.
  8. After drilling the hole, slowly withdraw the drill bit and cut off the water source of the power supply.
