How to calculate the formula for panel furniture drilling. What does multiples of 32 mean. For examp

Because all drill rows are multiples of 32 mm! Row drill calculation where to row holes, cabinet door panel up and down to leave 10 cm to 12 cm, calculation method cabinet door length minus 200-240 mm, and then divide by two, how much is the number obtained on the row of drills to find a closer number, such as 600 door panel, up and down minus 100 and divide 2 and so on 200. There are only multiples of 32 on the row of drills, so 192 is close, the drill bit is on 192, and then talk about the ruler, any row of drills has a ruler, that is, the goods that can be retracted, or the cabinet door of 600, the position of the ruler is 600 2, that is 300, one side of the ruler, the door is placed in the middle, and then take out the door and roughly measure the position of the ruler on both sides to the drill bit is different, almost OK (if it is a hole in the drill wardrobe three-in-one, I will generally take a small board and make a hole against the ruler to make a hole and compare, The hinge holes in the door panels are not so particular), and then the position of the holes to the side.

The hinge holes are all 35, and there are 4 mm from the edge of the hole to the side of the door, so the center of the hole is 35 2 plus 4 mm, and you have to count 21 mm, and then move the row of the upper drill bit to 21 mm, lock it, and then you can row the holes. Another way of punching is suitable for punching long doors, that is, on any position on the drill bit, both sides of the ruler from the drill bit 120, after punching one side, change the ruler to hit the other side.
