Slow wire walking, also known as low speed wire walking, is a kind of CNC machining machine tool that uses continuous moving fine metal wire (called electrode wire, generally copper wire) as the electrode, carries out pulse spark discharge on the workpiece, produces high temperature above 6000 degrees, corrodes metal and cuts into the workpiece. The principle of slow wire processing is that there is a gap between the online electrode and the workpiece, and the continuous discharge removes the metal phenomenon.

Slow wire is a kind of wire cutting, is the use of continuous moving fine metal wire (called electrode wire) as the electrode, pulse spark discharge on the workpiece corrosion metal, cutting molding. It is mainly used for processing a variety of complex shapes and fine precision workpiece, according to the electrode wire running speed is different, WEDM machine tools are usually divided into two categories: One is the slow wire (also called low speed wire EDM machine tool) electrode wire for low speed unidirectional movement, the general wire speed is less than 0.2m/s, the accuracy of 0.001mm, the surface quality is close to the grinding level. The finished surface is very smooth.

The electrode used for slow wire is copper wire, fast wire is used for molybdenum wire, and fast wire is reciprocating, slow wire can only be one-time, of course, the price of slow wire machine is high, the processing fee is high, the quality of the processed products is high, fast wire is on the contrary, now our company has in the middle of the wire is between the two, product quality and slow wire, the price is slightly higher than fast wire.

Precision of slow wire:

1. The precision of the slow wire is related to the model of the machine tool and the level of the operator. At present, the precision of the processing industry can generally reach 0.005mm.

2, slow wire is the use of continuous moving fine metal wire as electrode, pulse spark discharge on the workpiece, produce high temperature above 6000 degrees, corrosion metal, cutting into the workpiece is a kind of CNC machining machine. The principle of slow wire processing is that there is a gap between the online electrode and the workpiece, and the continuous discharge removes the metal phenomenon.

3, the surface roughness of the workpiece processed by the slow wire cutting machine can usually reach Ra=0.8μm and above. The roundness error, straight line error and size error of the slow wire cutting machine are much faster than that of the wire cutting machine. Therefore, when processing high-precision parts, the slow wire cutting machine has been widely used.
