Problems solved by technology

However, because the thickness of the insulating layer on the electrode will affect the depth of the hole formed by the exposed part of the electrode to the processing object, if the thickness of the insulating layer is thicker, the depth of the hole will be shallower, otherwise the depth of the hole will be deeper, so if formed If the thickness of the insulating layer of the electrode is not properly controlled, the depth of the formed hole will not meet the expected depth. In this case, the original electrode must be discarded, and a new electrode must be replaced to form an insulating layer on the new electrode. Increase the processing cost, and it is difficult to control the processing accuracy

Abstract

The invention relates to an electrochemical machining device and machining method and an electrode unit thereof. The electrochemical machining device comprises an insulation pipe and liquid metal in order to machine at least one workpiece; the workpiece and the insulation pipe are positioned in electrolyte; the insulation pipe comprises at least one hole; and the liquid metal is filled in the insulation pipe and extended into the hole for machining the workpiece for an electrode. In the invention, as the liquid metal is adopted as the electrode, the machining depth of the workpiece can be controlled by adjusting the position of the liquid metal extended into the hole, thereby improving the machining precision and saving the machining cost.

Description

technical field [0001] The invention relates to a processing device and method, in particular to an electrochemical processing device and method. Background technique [0002] Nowadays, electrochemical machining (electrochemical machining) has been developed, which is different from traditional machining methods. It is used to process extremely hard materials or materials or objects that are difficult to process by traditional machining methods. Electrochemical machining is also called electrolytic machining. When using electrochemical machining, the electrode is the cathode used as a tool, and the processing object is the anode, that is, the electrode and the processing object are respectively coupled to the cathode and anode of the power supply. The power supply goes from the processing object to the electrode through the electrolyte, so that the processing object can be processed, and the unnecessary part of the processing object is removed. Electrochemical processing doe...
