Woodworking planer one inch oblique nine how to draw

Woodworking planer drawing planer, one inch slant nine in the vertical direction is one inch, the horizontal direction of nine minutes, the equivalent angle is 49 degrees.

One Inch Slant Nine:

This is consistent with the protractor used by woodworkers nowadays to make planes. Today's woodworkers make planing grooves with a slope of 45° to 50°. According to the principle of trigonometry, we can know that the angle of the planer groove made according to the vertical 1-inch, inverted nine-minute scribe is 49°, which is consistent with the slope of the planer groove made with a protractor.

Woodworking planer:

Woodworking planer for the first time, the slope requirements are generally 45 degrees to 50 degrees, of which 45 degrees of the case, used to planing light wood, the fastest speed and the most effort, at this time the angle of each increase of one degree can be experienced people feel out.

Planer knives are mounted on the spindle at an angle of about 30 degrees, with the planer cutter angle at 20 to 45 degrees. In this case, it depends on the planer knife material and speed to increase or decrease the angle, and also using a knife that has been sharpened to increase its service life by about 70 percent.

Use of woodworking planer knife precautions

1, the use of woodworking planer knife, must be based on the use of the instruction manual introduced in the steps to operate, and never let the woodworking planer knife touch the cement, stone, metal objects, etc., otherwise it is easy to lead to the accident of these items splash injury.
