Find out the installation process of vertical drilling machine.

Vertical drilling machine, radial drilling machine and table drilling machine all belong to the category of drilling machine. Although their structural characteristics are different, their general principles and characteristics are the same. One of the typical characteristics is that the steps of workpiece drilling operation are similar. The drilling operation of vertical drilling machine is shown in the following figure. Strictly speaking, the concrete steps of vertical drilling machine include six steps, which are mainly divided into marking operation, checking squares and circles, drilling samples, installing fixtures, trial drilling and drilling.

1. Marking operation of six steps in drilling operation of vertical drilling machine

When drilling a workpiece, first of all, the master needs to be familiar with the drawings and understand the benchmark principle of workpiece processing. For example, the flatness of general datum is less than or equal to 0.04 mm, and the verticality of adjacent datum is less than or equal to 0.04 mm. According to the position and size requirements of vertical drilling machine, the reticle of drilling position is drawn with a height ruler, which requires clear and accurate marking and high precision. In addition, in order to determine the scribing accuracy after scribing, the scribing can be measured with vernier calipers and other tools.

After completing the marking operation in the previous step, you should continue to mark the check box or check circle with the symmetrical center line. Because of the trial drilling step, it is necessary to check and correct the position of the drilling hole when drilling. The size of the check box is different. The small square or circle is larger than the horizontal edge of the drill bit, and the large square or circle is larger than the diameter of the drill bit.
