Description

Frock clamp for cutting oxidized workpiece and cutting method Technical Field The invention relates to the technical field of self-tooling clamps, in particular to a tooling clamp for cutting an oxidized workpiece and a cutting method. Background The aluminum alloy is widely applied in the field of semiconductor equipment because of the advantages of small density, high strength, better corrosion resistance and the like. In order to further improve the hardness, wear resistance and corrosion resistance of the aluminum alloy surface, hard anodic oxidation treatment is often carried out on the aluminum alloy surface. For example, publication No. CN119571410A discloses an anodic oxidation treatment process of aluminum alloy, which comprises the following steps of (1) taking aluminum alloy as a base material, polishing the surface of the base material by using sand paper, then soaking the base material by using alkaline solution, (2) washing by water and drying by cold air, activating acidic solution, (3) washing by water and drying by cold air, (4) anodic oxidation treatment, (5) hydration hole sealing treatment, (6) washing by water and drying by cold air, wherein the solution used for the anodic oxidation treatment consists of 20-40g/L oxalic acid, 4-6g/L glycollic acid and deionized water, the anodic oxidation power supply is a direct current power supply, the aluminum alloy is used as an anode to be soaked in the anodic oxidation solution, the voltage is 40-50V, the temperature is 5-10 ℃, and the hydration hole sealing is carried out in water or water vapor at 98-105 ℃ for 2-3 hours.
