螺纹是用一台在轴上装有圆形毛毡的小电机，将其固定在桌面上，与桌子边沿成60度左右的角度，另外做一个装有固定铝板压茶的拖板，在拖板上贴一条边沿齐直的聚酯薄膜用来限制螺纹竞度。利用毛毡的旋转与拖板的直线移动，在铝合金手板表面旋擦出宽度一致的螺纹纹路。

 

The thread is a circular felt the shaft is provided with a small motor, which is fixed on the desktop, from the angle of about 60 degrees and the edge of the table, also equipped with a carriage fixed plate pressure tea, with a neat polyester film edge straight on the carriage to limit the thread of competition. With the rotation of the felt and the straight line of the trailing board, the width of the thread is wiped out on the surface of the aluminum alloy hand plate.

 

铝合金手板模型表面拉丝工艺可根据装饰需要，制成乱纹、直纹、波纹、螺纹和旋纹等几种。乱纹拉丝是在高速运转的铜丝刷下，使铝合金手板前后左右移动磨擦所获得的一种无规则、无纹路的亚光丝纹。这种加工，对铝或铝合金手板的表面要求较高。

 

The drawing process of the surface of the aluminum alloy hand plate model can be made into random, straight lines, ripples, threads and whirling lines according to the needs of decoration. The Striped wire is a irregular, no ripples in a high-speed wire brush, which makes the aluminum alloy hand moving around and around the rubbing. This processing requires higher surface requirements for aluminum or aluminum alloy hand plates.

 

直纹拉丝是指在铝合金手板表面用机械磨擦的方法加工出直线纹路。它具有刷除铝板表面划痕和装饰铝板表面的双重作用。波纹一般在刷光机或擦纹机上制取。利用上组磨辊的轴向运动，在铝或铝合金板表面磨刷，得出波浪式纹路。

The straight line drawing refers to the machining of a linear line by mechanical friction on the surface of the aluminum alloy hand. It has double effects on removing the scratches on the surface of the aluminum plate and decorating the surface of the aluminum plate. The ripples are usually made on the brush or wiping machine. With the axial movement of the upper group mill roll, the wave pattern is drawn on the surface of aluminum or aluminum alloy plate.

 

旋纹也称旋光，是采用圆柱状毛毡或研石尼龙轮装在钻床上，用煤油调和抛光油膏，对铝或铝合金板表面进行旋转抛磨所获取的一种丝纹。它多用于圆形标牌和小型装饰性表盘的装饰性加工。

 

Rotary grain, also known as optical rotation, is a kind of silk pattern obtained from rotary or polishing on the surface of aluminum or aluminum alloy sheets with cylindrical felt or stone nylon wheel mounted on drilling machine, kerosene and polishing ointment. It is mostly used for the decorative processing of round signs and small decorative dial.

 

拉丝是一种修复工艺，也可起到美观作用，因为金属表面局部有划痕，就整面用拉丝机作出一致的划痕<减小壁厚>淹盖局部划痕，*好不要用<经加工后有加工硬化，改变性能>，但划痕不好避免，所以又常用。拉丝不单有刷除铝板表面划痕，也有美化装饰铝板外观表面的双重作用。

 

The drawing is a repair process, can also play a beautiful role, because there is a scratch local metal surface, the whole surface of wire drawing machine make consistent thickness > < scratch to cover local scratch, it is best not to use "after processing processing sclerosis, but does not change the performance", to avoid scratches, and so common. Wire drawing does not only brush the scratch on the surface of the aluminum plate, but also has the double function of beautifying the surface of the decorative aluminum plate.
