Precautions For Clamping Workpieces

1) When clamping the workpiece, pay attention to the position of the code and the extension length of the nut and bolt on the pressure plate. In addition, the screw should not be on the top and bottom when locking the corner.

2) Copper males are generally processed for locking plates. Before starting the machine, the number of openings on the program sheet should be checked to ensure that they are consistent, and at the same time, check whether the closing screws are tightened.

3) For the case of receiving multiple copper materials on one board, check whether the direction is correct and whether each copper material interferes during processing.

4) The workpiece is clamped according to the shape of the diagram in the program sheet and the data of the workpiece size. It must be noted that the writing method of the workpiece size data is XxYxZ. At the same time, if there is a part diagram, it is necessary to check the diagram of the program sheet and the diagram of the part diagram Whether it matches, pay attention to which direction goes out, and the pendulum method of X and Y axes.

5) When clamping the workpiece, it must be checked whether the size of the workpiece meets the size requirements of the program sheet, and if there is a part drawing, it must be checked whether the size of the program sheet is the same as the size of the part drawing.

6) Before the workpiece is put on the machine, the worktable and the bottom of the workpiece should be cleaned. The machine tool table and workpiece surface should be pushed out with whetstone to remove the burrs and damaged positions.

7) When coding the code boy, make sure that the code boy will not be hurt by the knife, and communicate with the programmer if necessary. At the same time, if the bottom pad is square, the yard must be aligned with the square position of the pad to achieve the purpose of balanced force.

8) When using a vise for clamping, you must know the machining depth of the tool to prevent the clamped position from being too long or too short.

9) The screw must be placed in the T-block, and only a part of the thread must be used. If the screw needs to be connected, the upper and lower screws must each use half the thread of the joint, and the thread of the nut on the pressure plate must be completely used, not only a few threads. thread.

10) When setting the Z depth number, check the position of the single touch number in the program and the data of the highest point of Z. After entering the data into the machine tool, it must be checked again.
