现将我单位改进的选线用量角度盘制作方法介绍如下: 一、盘面:用直径22厘米的铝片,左右分刻0～180度,并加刻←左—·—右→,以便易于识别左右偏角。刻划的铝片钉固于厚约1厘米的不变形园木板上,木板稍大于铝片。二、指针:用长20厘米、宽1.2厘米较厚的无色透明胶片制成。底面刻划中线,涂上红色。两端胶上两个插针用的基座,使用时在基座中心针孔插上小
Now my unit to improve the line selection angle plate production methods are described below: First, the disk: with a diameter of 22 cm of aluminum, left and right sub-0 to 180 degrees, and add engraved ← left - · - right → for easy identification Left and right declination. Scratched aluminum nails fixed to a thickness of about 1 cm of the park garden board, board slightly larger than aluminum. Second, the pointer: with 20 cm long, 1.2 cm wide and thick colorless transparent film made. Scribe the center of the bottom, painted red. Both ends of the gel with two pins with the base, when used in the center of the base pinhole plug
