Woodworking 6 row drill how to row holes?

1, when drilling through the hole, such as once drilled through, it is necessary to add padding wood blocks under the workpiece; such as the thickness of the workpiece is greater than the length of the drill bit, should be drilled from both sides of the workpiece.

2. When drilling half-hole, the table should be lifted to the required height before drilling.

3. When drilling long holes, turn the table longitudinal feed handwheel to move the table left and right to the required position.?

4, when drilling slanting holes, use the mold with slope to fix the workpiece for processing.

5. When drilling multiple holes, for workpieces with small hole spacing, after drilling each hole, you can rotate the table longitudinal feed handwheel to move the table to the left or right by one hole spacing and then drill, without having to move the workpieces by loosening the presser.

6, drilling and milling mortise and tenon should be neat, not tilted, around the eye should be flat, no wrong table, wood chips, eye without stubble phenomenon. Row drilling on the drill row, a drill row of 21 holes, drilling the standard hole spacing is 32MM, in the head of the row of drills are a long ruler, there is a scale on it, there is also a positioning cylinder, as long as the beginning of the calculation of the scale, and then according to the distance you want to hole, find a reasonable position, set the position, so that you can batch drilling.

In the head of the row of drills are a long ruler, there is a scale on it, and positioning cylinders, as long as the calculation of the beginning of the scale, and then according to the distance you want to punch holes, to find a reasonable position, set the position, so you can batch drilling.

The formula for calculating the hole position is: (a-32x)/2 rows of 3 holes in the middle of the above and then 32x/(n-1) a is the length of the perforated plate X is the individual perforation habits depending on that is not fixed n is the number of holes need to be rows of holes, for example, a 1000 length of the plank row of 2 holes is (1000-35 * 25)/2 = 100 two holes distance is 32 * 25 = 800
