1、浮屠状卷屑：数控加工、机床或自动线加工时，氧化铝板研发专家指出，期望得到此形屑，由于这样的切屑不会缠绕在刀具和工件上。并且整理也便利。
1. Floating chip: in NC machining, machine tool or automatic line machining, aluminum oxide plate R & D experts point out that this kind of chip is expected, because such chip will not wind on the tool and workpiece. And it's convenient to organize.
2、崩碎屑：在车削铸铁、脆黄铜、铸青铜等脆性资料时，氧化铝板研发专家指出，很简单构成针状或碎片状的崩碎屑，既易飞溅伤人、又易研损机床。若选用卷屑办法，则可使切屑连成短卷状。
2. Chipping: when turning brittle materials such as cast iron, brittle brass and cast bronze, experts on research and development of aluminum oxide plate pointed out that it is very simple to form needle like or fragment like chipping, which is easy to splash and damage the machine tool. If the chip curling method is selected, the chips can be connected into short coils.
3、发条状卷屑：在重型车床上用大切深、大进给量车削钢件进，切屑又宽又厚，若构成C形屑则简单损伤切削刃，基至会飞崩伤人。氧化铝板研发专家指出，所以通常将断屑槽的槽底圆弧半径加大，使切屑成发条状在加工外表上磕碰折断，并靠其自重掉落。
3. Spring like chip: turning steel parts with large cutting depth and large feed rate on heavy lathe. The chip is wide and thick. If C-shaped chip is formed, the cutting edge will be damaged easily, and the base will collapse and hurt people. According to the research and development experts of aluminum oxide plate, the radius of the arc at the bottom of the chip breaking groove is usually increased, so that the chips become hairy strips, which are bumped and broken on the surface of the processing, and fall off by their own weight.
4、带状屑：高速切削塑性金属资料时，氧化铝板研发专家指出，如不采纳断屑办法，很简单构成带状屑，此形屑源源不断，常会缠绕在工件或刀具上，易划伤工件外表或打坏刀具的切削刃、乃至伤人，因而应尽量防止构成带状屑，但有时也期望得到带状屑，以使切屑能顺畅排出。例如在立式镗床上镗盲孔时。
4. Banded chip: when cutting plastic metal materials at high speed, the research and development experts of aluminum oxide plate pointed out that if the chip breaking method is not adopted, it is very simple to form banded chip. This kind of chip is in continuous flow and often entangles on the workpiece or tool, which is easy to scratch the surface of workpiece or damage the cutting edge of tool, or even hurt people. Therefore, banded chip should be prevented as far as possible, but sometimes it is expected to get banded chip to make the cutting surface smooth The chip can be discharged smoothly. For example, when boring blind holes on a vertical boring machine.
