1. The electrolytic deburring

This is the use of power, chemical energy dissolve anode remove burr. Parts and dc power supply in the positive side for anode, forming tools and dc power anode connected as the cathode, between the poles to keep a space, let the electrolyte circulation flow. When the anode and Yin level and ventilation with dc dipped into the solution, anticathode surface electrochemical reactions happen, parts of the surface is dissolved metal and electrolyte viscous liquid form concentrated in parts of the surface DiAo place, has the high resistance and the smaller corrosion; And burr outstanding on parts surface, under the influence of the temperature difference, liquid membrane is difficult to form, after electrify power line heavily focused on the part of the cathode recently from deburring with quickest speed to dissolve deburring, until burr dissolve, gradually formed rounded edge, namely to deburr purpose.

Can use electrolytic deburring machine tools. When the production batch is not big, can be made into dc and ac rectifier simple equipment. According to the parts structure, manufacture and the shape of the special jig similar parts (tool cathode), with brass or copper and conductive good material to make, not processing parts with epoxy resin isolation protection. Commonly used electrolyte have NaCl, NaNO2 > and NaNO > 3 and solution.

This method is suitable for non-ferrous, black metal parts, especially suitable for complicated shape parts and machinery, manual method with hard purify hole, cross hole and the inner surface of burr, can remove very hard parts such as molybdenum, nickel, titanium, quenching parts of burr.
 
2. Chemical deburring

Will clean metal parts in chemical solution (50 ℃), metal parts surface with ion form turned to solution. These ion gathered at the surface of workpiece, the chemical reaction form a layer of resistance, electric conductivity small mucous membrane, protect the surface not corrode, and burr outstanding at the surface, chemistry will burr removed.
 
Processing, as long as a tank can. According to the different deburring workpiece materials, with different chemical solution. The main ingredients can be hydrochloric acid, phosphoric acid, sulphuric acid, hydrochloric acid, water and the two aniline and, according to the proportion preparation. Chemical deburring applicable to small metal parts, can remove thickness is less than 0.07 mm of tiny burrs.

3. High temperature deburring

First will need to tighten the parts in the deburring sealing indoor, and then sent into hydrogen gas mixture of certain pressure, the spark plug, mixed gas instantaneous blast, give off a lot of heat, instantaneous temperatures as high as 300 more than 3 ℃. Because explosion time is very short, the parts of the burr be burned off, and other parts of the parts can change. Exploded, high pressure gas pervasive, all the parts in the hole and cross holes, grooves, deep hole etc all can be burned off the burr. Need to have special high temperature deburring machine tools.

This method to burr is applicable to any structure to the shape of the metal, plastic, rubber parts, especially complex shape and with manual and difficult to remove burr parts. The operating process, according to the different components of the materials to choose the appropriate oxyhydrogen mixing ratio (refers to seal chamber hydrogen and oxygen Moore quality than), steel, alloy steel, copper is not sensitive to the mixture, oxyhydrogen mixing ratio in the 2-1 ~ 2:2 scope may, aluminum alloy slightly higher than the 2-1. And then choose the charge pressure (refers to seal indoor the mixture pressure), generally speaking, steel, alloy steel air pressure is high, the brass is the second smallest, and aluminum alloy lower. Parts in deburring before, must be clean and dry; Deburring. Add in phosphoric acid mixture with processing, remove oxidation film.

4. Roll grinding deburring

Put a percentage of the workpiece and abrasive into closed roller in the roller in the process of turning, parts and abrasive, parts and parts produced between grinding, remove burr. Rolling mill deburring equipment to have special deburring machines and centrifugal cast rolling machine.
 
Abrasive available quartz sand, wood chips, alumina, ceramics, dolomite, silicon carbide, metal ring, etc. According to the parts of the materials, shape and size and burr parts and size selection.
With this method, small part deformation, the equipment is simple, easy to operate, abrasive source wide, economical, but big burr hard to remove.
