The bench drill is a small hole processing machine tool that is small in size, easy to operate, and usually installed on a special workbench. The bore diameter of bench drilling machines is generally below 13 mm, and generally not more than 25 mm. The spindle speed change is generally realized by changing the position of the V-belt on the tower pulley, and the spindle feed is manually operated. The following editor introduces the use and maintenance of the safety operation rules of bench drills.
Safety operating procedures for bench drilling machines
1. The operator must be familiar with the machine’s performance, purpose and operation precautions before operating. Novices are strictly prohibited from operating on the machine alone.
2. Operators must wear appropriate clothes and gloves when operating.
3. Start the dust collection system before operation.
4. Before starting the machine, check whether the voltage and frequency on the circuit board are consistent with the power supply.
5. The contact pins on the power plug and socket of the machine tool should be reliable, and there should be no looseness or poor contact.
6. The wires should be kept away from high temperature, greasy, sharp edges, and the machine tool should be grounded. Do not pull the power cord on the socket forcefully.
7. When an accident occurs, the power supply should be cut off immediately before maintenance.
8. When the machine tool is working or overhauled, a protective cover should be installed around the work site.
9. Keep the work area clean and tidy. Do not use the machine tool in a messy, damp, weak light, flammable and explosive place. The operator’s hair should not be too long to avoid being caught during operation.
10. Don’t perform work that exceeds the cutting capacity of Z to avoid overloading the machine tool.
11. Do not operate the machine after drinking or fatigue, keep the machine upright, and do not overturn it.
12. Regularly maintain the machine to maintain the sharpness of the drill bit, and pay attention to adding cutting fluid when cutting.
13. Before use, carefully check the vulnerable parts of the bench drill so that it can be repaired or replaced in time.
14. When drilling holes with larger diameters, use low speed for cutting.
15. The handle that should be locked must be locked before the machine works, and the workpiece should be clamped reliably.
16. When the operator wants to leave his post due to an incident, he must shut down the machine first, so as not to talk with others during the operation.
17. When the machine is running abnormally, it should be shut down immediately and handed over to a professional for overhaul, and the power supply should be disconnected during overhaul.
18. The sawdust around the machine must be cleaned up before leaving get off work. Sawdust is not allowed to accumulate on the motor, and the daily maintenance of the equipment must be done.
19. This machine is a dedicated machine for personnel. It is strictly prohibited for non-operators to start the operation, and the operator who insists on the operation is responsible for the consequences.
Maintenance and cleaning of bench drills:
1. Clean up the debris on the countertop in time after the work is completed
2. Regularly oil the spindle and chuck
3. Regularly check the tension of the spindle belt
4. When not in use for a long time, apply butter on the surface to prevent the surface from rusting
5. Regularly clean the burrs on the surface of the chuck
