Price 10.00 yuan7 For straight-line gas cutting machines, use a marking pen to mark two parallel long lines in the longitudinal direction according to the maximum working width. Use a compass with a radius of at least 3m to draw two perpendicular lines with equal spacing to the width on the two long lines to form a square. Measure the two diagonals, and the calculated absolute value should meet the requirements of 63.8. 7.2.8 The plate thickness range of low-carbon steel samples cut by photoelectric tracking and CNC gas cutting machines is 16-20mm. Cut out a figure with a 30° angle as shown in Figure 8. After cutting, the cut surface of the sample should meet the requirements of 6.3.9, 30
