双头薄板切割器是一种以电气钻为动力的切割器，它可双头切割2毫米以下薄板，当一头切割变钝时可换另一头继续切割，无论切割平面还是曲面板材，均可作直线、曲线、圆弧或其它不规则线条切割，当配上固定台架后可切割55毫米—260毫米标准规则圆孔。本产品具有重量轻、体积小、操作简便等特点，是汽车修理、家居装修、钣金制作、及新产品开发的理想工具。 1． 刀头刃口处勤加油特别是切割铝板尤为重要。 2． 先开电钻后切割，结束时先退出后关电钻。 3． 切割时刀杆与钢板必须保持垂直，严防硬蹩折断刀头 4． 切割圆弧时应使用固定支架，以便圆弧过渡光滑漂亮。 5． 切割圆弧时应先钻出一个11毫米及3毫米定位孔，将刀头伸入再进行切割。 6． 固定台架与电钻配套孔为45毫米，当电钻孔径发生变化时应配上相应衬垫，使其牢固固定。 打开护盖1，取出防松螺丝2，松开紧定螺丝2，对准刀杆上的定位孔，按尖头方向用钳子拔出刀杆3，重新装上刀杆，拧紧螺丝即可。 逆时针旋出压紧帽4，将新刀头放入即可。 1． 刀杆材料及硬度：高速成钢淬硬HRC58-60。 2． 割缝3MM。 3． 配套电钻（气钻）8MM，功率260W，转速1600-2600。 4． 允许切割厚度：2MM内不锈钢板、铁板、铝板、铜板等金属板材，2.5MM内蜚金属板材均可任意切割。 5． 新版精装型产品备有切割圆弧的固定台架，切割圆弧直径为55MM-260MM。 Characteristics and application Double-head sheet metal nibbler is powered by electric driller for cutting of metal sheet below 2mm.Ithas two die heads for cutting,and when one becomes dull,you can use the other to cut metal sequentially Not,only cutting plane but also cutting curve,it can cut along line,curve,circular and other irregular shapes.When attached with fixed shand,it can cut standard circle,the diameter of which is from 55mm to 260mm.Compared with other similar product,it is light,small dimension and easy to operate.It is widely used in automobile repair,household,metal sheet and developing new product. Operation attentions 1. Add oils to blade of die head often,especially cutting aluminum sheet. 2. Start up electric driller bdfore cutting,and turn off electric driller after finishing cutting. 3. Keep the sheet metal vertical with the punch needle to avoid breaking of die head. 4. Use fix stand when cutting circular in order to make it beauty. 5. Drill an 11mm hole and a 3mm hole for position before cutting circular,and put the die head in hloe for cutting. 6. The diameter of the clipping holc of the fix stand matched with the driller is 45mm.And if the driller hole is changed,you can add certain rubber or plastic linings to make driller clippep tightly. Replacement of the punch needle Open cover(1),take out fastening screws(2)and unfasten the screw(2),pull out punch needle(3)along direction of point head and install a new punch needle,then fasten the screw. Replacement of the die head Screw out the fastening nut(4)counter clockwise and install new die head Main technical parameters 1. Material and hardness of punch needle:high speed steel and HRC58-60. 2. Seam of cutting:3mm 3. Matched electric or air driller:8mm,power more than 260W,speed from 1600rpm to 2600rpm. 4. Permission thickness of cutting sheet:metal less than 2mm,and other material less than 2.5mm. 5. New style product with fix stand for cutting circular,and it can cut circular from 55mm to 260mm
