Drilling rig operating procedures and skills: how to use the drilling rig correctly
August 25th
1, Drilling rig operating procedures
1. Safe operation of drilling rig:
① Before each use of the drilling rig, check whether the wires are damaged, whether the motor is normal, and whether the drill bit is firmly fixed.
② During operation, safety equipment such as helmets, gloves, and goggles should be worn to ensure the safety of personnel.
③ During operation, one should remain sober and avoid behaviors that expose individuals, such as drinking alcohol, smoking, or playing with mobile phones.
④ Appropriate coolant should be used during drilling to protect the drill bit and workpiece from thermal deformation.
⑤ After the drilling is completed, the power supply of the drilling rig should be turned off, and damaged wires, motors, and other aging equipment should not be reused.
2. Common troubleshooting of drilling rigs:
① Motor cannot start: Check if the power is connected and if the wires are damaged.
② Drill bit is prone to breakage: Check if the drill bit is worn, if the protective sheath is intact, or it may be due to factors such as material processing thickness.
③ The drill bit is stuck and not turning: Check if the motor is working properly and if it needs timely maintenance such as adding lubricant.
④ Damage caused by drill bit fracture requiring secondary processing: Check the quality, diameter, length, applicable materials, drilling position, etc. of the drill bit.
3. Maintenance and upkeep of drilling rig:
① After a period of use, the drilling equipment should be cleaned, oiled, and maintained to ensure its normal operation.
② During use, regularly check the condition of cables or wires, and replace them promptly if any damage is found.
③ Before use, the drill bit should be dry ground with the workpiece and regularly lubricated and protected to extend its service life.
④ When the drilling rig is not in use, it should be placed in a dry and sunny place to avoid moisture and damage.
2, Drilling rig operation skills
1. Choose a suitable drill bit:
The selection of drill bits is mainly influenced by various factors such as material hardness, aperture size, and working area. In addition, different brands of drill bits may be suitable for different workpieces, so when purchasing drill bits, one should choose the appropriate brand and specifications according to their own work needs.
2. Pay attention to processing speed:
The processing speed cannot be too fast or too slow. Too fast can lead to uneven drilling depth, while too slow can result in low processing efficiency, wasting time and resources.
3. Pay attention to the use of coolant:
When drilling, an appropriate amount of coolant should be used to help dissipate heat from the drill bit; At the same time, it can also avoid problems such as metal debris, oil stains, burrs, etc., and improve processing efficiency.
4. Avoid excessive heat:
Due to the influence of high temperature heat during drilling, the drill bit may experience cracks, deformations, etc., so it is necessary to regularly cool and protect the drill bit.
5. Pay attention to the processing environment:
When drilling, the working environment should be kept clean and hygienic to avoid damage to the machine from metal debris, chips, oil stains, burrs, and other pollutants, as well as injury to operators.
This article mainly introduces the operating procedures and related skills of drilling rigs, including safe operation of drilling rigs, common fault handling, maintenance, etc. During the use of the drilling rig, it is necessary to follow the regulations and master the relevant operational skills. I hope this article can provide readers with help to ensure the safe and efficient use of your drilling rig.
