What Factors Will Affect The Wire Cutting Processing
Slow-wire cutting and thread cutting are two different of machining methods in precision CNC Machining industy. Due to slow-wire cutting is greater than thread cutting on the roundness errors, line errors and size errors, so it’s widely used in the production of high precision machined parts. However, in the process of production, slow-wire cutting will also to be affected by some external factors, so Creatingway will take this blog to explain these information to our customers.
We will share some factors to affect the wire cutting processing.
Arrange slow-wire cutting route properly
By this way, it can effective to avoid damage the original balance of internal stress, and protect the workpiece due to fixture etc, resulting in cutting route is not reasonable arrangement and deformation, thus to decline the surface quality of the parts.
Fixed the workpiece
The connection strength of the raw material will decrease after cutting. At this time, we will need to notice that it’s important to avoid the deflection of the machining parts due to the impact of the processing fluid. In case of deflection, it will directly cause the change of cutting clearance and result in the surface quality of the workpiece, even it will directly affect the workpiece is broken and scrapped. So the fixed workpiece is very important for cnc machining parts.
Using few amounts and multiple-times cutting way
In general, the machining amounts is based on machine tool processing parameters to determine. According to the previous machining experience, the workpiece surface quality will be better when the machining amounts reduce. Because of the deformation of the material can improve the surface quality of the workpiece by reducing the wire cutting processing. So and for now, more and more suppliers choose to use few amounts and multiple-times cutting methods to improve the surface quality of the parts.
Select the cutting parameters correctly
For different roughing and finishing, the cutting parameters must be adjusted in time. Such as: wire speed, wire tension and flow pressure etc. By adjust them, we can ensure the machined workpiece high precision and high surface quality.
Although each equipment has own a certain cutting conditions supporting parameters, but due to the workpiece material, the machining precision of the parts and other factors influences, we need to make corresponding parameters adjustment according to the actual situation.
Using tight machining way
For the workpiece to achieve high precision and high surface quality, generally we can also use tight machining way to shorten the distance of the upper nozzle and the workpiece, thus to prevent the surface quality of the workpiece from being affected by the distance of the nozzle and the workpiece.
