The universal angle ruler seems simple, but if you haven't read the manual carefully, many students may not be able to use it. Today, the editor of CNC expert has compiled a graphic tutorial for the students, I hope it will be helpful to everyone.

2. Reading and using method of universal angle ruler

When measuring, adjust the position of the square or ruler first according to the condition of the measured part of the product, fasten them with the screws on the clamp, and then adjust the angle between the measuring surface of the base ruler and other relevant measuring surfaces. At this time, first loosen the nut on the brake head, move the main ruler for coarse adjustment, and then rotate the micro-movement device on the back of the fan-shaped plate for fine adjustment until the two measuring surfaces are closely attached to the measured surface. Then tighten the nut on the brake and take off the angle ruler for reading.

(1) Measure the angle between 0°-50°

Both the square and the ruler are installed, and the measured part of the product is placed between the measuring surfaces of each ruler of the base ruler for measurement.

 

(2) Measure the angle between 50°-140°

You can remove the square and install the ruler to connect it with the fan-shaped board. The measured part of the workpiece is measured between the base ruler and the measuring surface of the ruler.

 

It is also not necessary to remove the square, just remove the ruler and the clamp, and then pull the square to the bottom until the intersection of the short and long sides of the square is aligned with the sharp edge of the base ruler. Place the measured part of the workpiece between the base ruler and the measuring surface of the short side of the square for measurement

 

(3) Measure the angle between 140°-230°

Remove the ruler and the clamping block, and only install the square, but push the square up until the intersection of the short and long sides of the square is aligned with the sharp edge of the base ruler. Place the measured part of the workpiece between the base ruler and the measuring surface of the short side of the square for measurement.

 

(4) Measure the angle between 230°-320°

Remove all the square, ruler and clamps, leaving only the fan-shaped board and the main ruler (with base ruler). Place the measured part of the product between the base ruler and the measuring surface of the sector plate for measurement.
