How To Use The Electric Coring Machine

How to use the electric coring machine

1. Move the machine to the place where the core needs to be drilled, screw four adjusting screws (5) on the base to adjust the level of the machine, and tap M16 iron expansion bolts at the core to fix the machine.

2. Install the drill according to the size of the drilled 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 a few minutes, and turn the feed handle to drill.

Electric coring machine precautions

1. When drilling, the feed speed should be uniform, about 3-5cm/min. If the drill bit is found to be stuck, the feed speed can be appropriately reduced. If necessary, the drill bit can be lifted to a section. Supplier Hebei Dahong Experimental Instrument Co., Ltd. Company, and then slowly drill, 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. At the end of drilling, the machine can be stopped only when the drill is separated from the workpiece.

4. 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.

Electric coring machine maintenance

1. Regularly check the connection of each component, and adjust it in time if it is loose.

2. When the drill bit is installed, lithium-based grease should be added to the two threads.
