Used machine tools
In the electroerosion
category, the machines designed to realize wire machining operations are characterized by the high level of precision they achieve, as well as, speed, productivity, and flexibility they offer to their users.
They are therefore particularly suitable for all types of precision operations relevant to general mechanics.
The general principle of electroerosion machining is the following: disruptive discharges are exerted on the workpiece and via an electrode thus the deteriorated particles are cooled and drained through a continuously filtered dielectric liquid.
As far as wire erosion
machining is concerned, the electrode in question is constituted by a conductive wire. Following a cutting up movement, angular or combined, this wire is used to cut up very hard materials pieces, mainly conductive materials.
The method permits the machining operations on small parts and the processing of the smallest details and shapes, which is far more complicated or even impossible using conventional machine tools; which makes this process widely used in the manufacture of injection molds.
As for the material constituting the electroerosion wire, it may be made of brass, copper, tungsten, zinc, etc. It is renewed continuously, going from a supply reel to another.
On the second-hand market, many electroerosion wire machines are for resale. For most of these models, particularly those which go through RDMO workshops, the levels of quality and efficiency are extremely close to those offered by new machines. A rigorous checking, conducted by teams of confirmed expertise, is a guarantee.
Several well-known brands are famous worldwide for the quality of their machines helping to realize electroerosion wire operations. Among them, Charmilles
, Makino Milling Machines, Mitsubishi EDM, Sodick
, ONAElectro-Erosion, Knuth Machine Tools, Bedra Berkenhoff, 600 Group, KAAST Werkzeugmaschinen GmbH, Accutex, Aristech, Chmer, Joemars, Kent Industrial, and Maxseeconstituent are real references.
