1、浮屠狀卷屑：數控加工、機床或自動線加工時，氧化鋁板研發專家指出，期望得到此形屑，由于這樣的切屑不會纏繞在刀具和工件上。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：在車削鑄鐵、脆黃銅、鑄青銅等脆性資料時，氧化鋁板研發專家指出，很簡單構成針狀或碎片狀的崩碎屑，既易飛濺傷人、又易研損機床。若選用卷屑辦法，則可使切屑連成短卷狀。
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、發條狀卷屑：在重型車床上用大切深、大進給量車削鋼件進，切屑又寬又厚，若構成C形屑則簡單損傷切削刃，基至會飛崩傷人。氧化鋁板研發專家指出，所以通常將斷屑槽的槽底圓弧半徑加大，使切屑成發條狀在加工外表上磕碰折斷，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、帶狀屑：高速切削塑性金屬資料時，氧化鋁板研發專家指出，如不采納斷屑辦法，很簡單構成帶狀屑，此形屑源源不斷，常會纏繞在工件或刀具上，易劃傷工件外表或打壞刀具的切削刃、乃至傷人，因而應盡量防止構成帶狀屑，但有時也期望得到帶狀屑，以使切屑能順暢排出。例如在立式鏜床上鏜盲孔時。
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.
