Second hand drilling machines mainly refer to machine tools that use drill bits to process holes on workpieces. Usually, the main motion is the rotation of the drill bit, and the forward movement of the drill bit axis is the feed motion. The drilling machine has a simple structure and relatively low machining accuracy, which is very popular among large enterprises. Drilling machines can be roughly divided into vertical, desktop, rocker arm, and deep hole drilling machines. Here, the editor will give an example of a rocker arm drilling machine and provide a detailed introduction to the 6 precautions for using a rocker arm drilling machine, hoping to be helpful to everyone.
1. Before drilling, when aligning the workpiece position, the locking device should be loosened, and the extension length of the feed spindle should be adjusted appropriately according to the drilling depth. Then, lock each locking device tightly.
2. When adjusting the automatic cutting tool for drilling depth, the operator should first make the drill bit contact the workpiece, then adjust the feed block to the required depth value and lock it.
3. Operators need to pay attention to the sharpness of the tools, and blunt tools should not be used again to prevent accidents.
4. The height of the hydraulic rocker drill should be adjusted appropriately during work and should not be too high. During the machining process, the rocker arm and spindle box must be in a clamped state.
5. During the drilling process of hydraulic rocker drill, the drill bit must not be stopped before it has withdrawn from the workpiece. When reversing, it is necessary to wait for the spindle to stop before starting.
6. When parking for more than eight hours before starting the equipment, it should be operated at low speed for five minutes to confirm that the lubrication system is unobstructed and that all transmissions are normal before starting work.
