The operating procedure of the drilling machine is to make preparations before starting the machine and carefully check whether all parts of the drilling machine are complete. When using a drilling machine, it is necessary to pay attention to the feed speed, adjust the appropriate rotational speed, and pay attention to the details of positioning. Next, we will introduce the relevant content in detail.
1、 Operating Instructions for Drilling Machines
Preparation before startup
① Carefully check whether all components of the drilling machine are complete. ② Check whether the screws are loose. ③ Whether the lubricating oil meets the required level. ④ Whether the control buttons are flexible and reliable. ⑤ Whether the drill pipe and drill bit are damaged. ⑥ Check whether the support hole frame is broken. ⑦ Whether spray facilities are installed in place.
Normal startup
① Idle the drilling machine for 1 to 2 minutes and carefully listen for abnormal noises and noises. ② Drill slowly at low speed. ③ The drilling speed can be adjusted appropriately if there is no abnormality in the low gear and there is no gangue in the coal seam. If the coal seam always contains gangue and the hardness of the gangue is large, the drilling speed can only be adjusted using the low gear.
2、 Attention Details of Drilling Machine
1. Feed speed
When using, it is important to pay attention to the feed speed. However, the feed speed is generally based on experience, which is generally 0.08-0.12mm/revolution, or 0.6-1.0mm/second in numerical terms. Feed speed is a key factor in drilling, and different feed rates produce different feed rates.
2. Pay attention to positioning
When using a drilling machine, it is important to pay attention to positioning. When using a drilling machine, workers generally need to draw a number on the place where the hole needs to be drilled, which can ensure the accuracy of the drilling position. When using a center chisel to punch the positioning point, ensure that the center chisel is perpendicular to the surface of the workpiece to avoid affecting the smooth discharge of the cutting core.
3. Adjust the appropriate rotational speed
When starting drilling, it is necessary to adjust the appropriate rotational speed. Before starting the drilling machine, it is necessary to ensure that the bottom of the drilling machine is clean, and then turn on the drilling machine switch. Then, when turning on the motor switch, it is necessary to simultaneously turn on the coolant switch while the motor is running. When the drill bit contacts the steel plate, it is necessary to feed slowly, and after entering about 1-2 mm, it is then fed at the normal speed.
4. Turn off the motor at the end
The next point is to turn off the motor at the end of drilling, and then wait for the spindle to stop rotating. After that, use an iron hook to remove the iron filings wrapped around the drill body, and then continue the operation.
