What are the precautions when using a drill
2022/08/26
There are many precautions when using the drill. Below we summarize some related matters for you, you can take a look.
The first point: do proofing and eye-catching
The specific method is to use the drill bit to lay a small point first, and then make observations in all directions of the cross center line, mainly to observe whether the position of the proofing punch is standard and correct. In the case of confirming that there is no mistake, the proofing can be punched to the level of punching and rounding, so that the core can be accurately identified. It can be said that this can improve the accuracy of the drilling position. As long as the sample hole is accurately drilled, the accurate position of the drill core can be ensured, so that the drilling can be done successfully once. If it is misaligned, then the final drilled hole is also misaligned, and this result cannot be remedied. Therefore, the experienced operator must identify the sample eye before punching.
The second point: pay attention to the operation of clamping
The specific method should be to clean the machine tool with a rag, and then clamp the workpiece frame as much as possible. It is required that the clamping should be flat, the clamping should be firm, and the observation and measurement of the operator should be convenient. However, we must pay attention to the method and method of clamping, because incorrect clamping will cause the workpiece to be deformed.
The third point: do a good job of trial drilling
Before the official drilling, it is necessary to drill in cash form. The specific method is to align the chisel edge of the drill bit with the center of the drilling hole, first drill a small shallow pit, and then use the method of visual inspection to see whether the position of the shallow pit is correct. Often this link needs to be adjusted continuously. Only when the position of the shallow pit reaches the position of the inspection square or the axis of the inspection circle can be completely coincident, the next process can be carried out, and finally a satisfactory hole is drilled.
