Instructions for use
for the

Steel angle grinding gauge

1) Hach Fig. 1 are from the table on the back of the slide on the Eelhe "cast steel up to 50 kg strength ¹¹ from the columns ^M Ha ^M for the

Clearance angle » 5 ° /
for the rake angle = 10 °
taken.

2) According to Fig. 2 , 5 ° for the clearance angle, 10 for the SDanwinkel on the full degree arc between 50 -0 - 30 are set on the arc segment; the locking screw is tightened. The teaching is discontinued!

3) According to Fig. 3 , the steel placed on the steel support is brought up to the measuring edge for the clearance angle and the condition of the clearance area is checked. In the case of hard metal steels, it is necessary to check the open area that has been ground free by another 2.

4) According to Bjld 4 , the correct rake angle is checked; for this purpose, the steel placed on it is brought as far as possible to the rake angle measuring edge with the slide.

5) In Figure 5 it is possible to test any tip angle, for this purpose the division 0-90-0 is used. Depending on the length of the steel and the size of the angle, the slide must be pushed back accordingly.

6) Sech Fig. 6 is moved when measuring the cutting edge height. The finished steel is measured together with the prospective documents, which are then increased or reduced by the possible difference.

Claims (3)

• Bruno Koppen Berlin-Wilmersdorf Sächsische Str. 41, December 17, 1955 right to protection regarding steel angle grinding gauge 1) Steel angle grinding gauge characterized by that an additional arc segment enables the simultaneous setting and checking of the span and rake angles allowed. 2) Steel angle grinding gauge according to 1, characterized in that that an additional measuring nose is provided that in conjunction with a scale on the Rod and a vernier on the slide the measurement of the cutting edge height is possible. 3) steel angle grinding gauge according to 1 and 2 characterized in that that the back side of the slide with a table of the cutting angle values for steels High-speed steel and carbide is provided.
