Chemical burr clean method

Chemical burr clean method is suitable for small  metal parts CNC milled workpiece Principle and method of chemical burr clean: Put the cleaned metal parts into the chemical solution (50 ℃), and the metal on the surface of the parts will be transferred into the solution in the form of ions. These ions gather on the surface of the  metal workpiece  and form a layer of viscous film with large resistance and small conductivity through chemical reaction to protect the surface of the workpiece from corrosion, while the burr protrudes out of the surface, and the chemical action will remove the burr. Aluminum prototypes manufacturing Chemical burr clean method: During processing, only one slot is needed. According to different deburring materials, different chemical solutions are used. The main components can be hydrochloric acid, phosphoric acid, sulfuric acid, diphenylamine hydrochloride and water, etc., which are prepared in proportion. Chemical deburring is suitable for small m

CLEAN BURRS BY ELECTROLYTIC METHOD

Electrolytic burrs cleaning method is suitable for non-ferrous and ferrous  metal parts . Especially for parts with complex shapes, inner holes, cross holes and inner surface burrs that are difficult to remove by mechanical and manual methods. And can remove the burrs of extremely hard parts such as molybdenum, nickel, titanium and quenched parts. Working principle of Electrolytic burrs cleaning method This is to use electric and chemical energy to dissolve the anode and remove the burr. The positive side of the part and the DC power supply is the anode, and the negative side of the forming tool and the DC power supply is the cathode. There is a certain gap between the two sides to let the electrolyte circulate. When the anode and the cathode are immersed in the solution and connected to the direct current, the electrochemical reaction occurs on the anode surface, the metal dissolved on the part surface forms viscous liquid with the electrolyte, which is concentrated in the low

MACHINING PARTS CLEAN BURR METHODS

This article introduced some  machined parts  burr cleaning methods. Electrolytic deburring This is to use electric and chemical energy to dissolve the anode and remove the burr. The positive side of the part and the DC power supply is the anode, and the negative side of the forming tool and the DC power supply is the cathode. There is a certain gap between the two sides to let the electrolyte circulate. Chemical deburring Put the cleaned metal parts into the chemical solution (50 ℃), and the metal on the surface of the parts will be transferred into the solution in the form of ions. These ions gather on the surface of the  machined workpiece  and form a layer of viscous film with large resistance and small conductivity through chemical reaction to protect the surface of the workpiece from corrosion, while the burr protrudes out of the surface, and the chemical action will remove the burr. High temperature deburring First place the parts to be deburred in the tight sealing

WHY DOES STAINLESS STEEL RUST?

Stainless steel widely used to produce all kinds of  machinery part  to avoid rust. But Stainless steel will rust under certain conditions. Why does stainless steel rust? When there are brown rust spots (spots) on the surface of stainless steel pipes, people are surprised to think that “stainless steel is not rusty, rust is not stainless steel, maybe there is a problem with the steel quality”. In fact, this is a one-sided wrong view of the lack of understanding of stainless steel. Stainless steel will rust under certain conditions. stainless steel CNC turned part Stainless steel does not rust It also produces an oxide on the surface. At present, all stainless steel on the market is due to the presence of Cr element. The basic reason (mechanism) of stainless steel corrosion resistance is passivation film theory. The so-called passivation film is a layer of Cr2O3 based film on the surface of stainless steel. Due to the existence of this film, the corrosion of stainless steel mat
