What VDI 3400?

VDI 3400 texture refers to the texture standard set by Verein Deutscher Ingenieure (VDI), the Society of German Engineers. It is mainly processed by Electrical Discharge Machining (EDM) when mold machining but could also be done by the traditional texturing method.

What is VDI on an EDM machine?

VDI 3400 Surface Finish – is a scale often used by German machine manufacturers and quite widely used in Spark and Wire Erosion (Verein Deutscher Ingenieure, the Society of German Engineers) Charmilles EDM surface finish chart.

What is a VDI finish?

VDI 3400 Surface Finish (commonly known as VDI surface finish) refers to the mould texture standard set by Verein Deutscher Ingenieure (VDI), the Society of German Engineers. The VDI 3400 surface finish is mainly processed by Electrical Discharge Machining (EDM) when mold machining.

What is SPI surface finish?

The SPI Finish refers to the American surface finish standard set by SPI (Society of the Plastics Industry). The standard covers 12 SPI grades of polish finishes: SPI A1 to #SPI D3 (RA 0.012 μm to RA 18.00μm).

What is EDM texture?

An EDM surface finish is different to one produced by conventional material removal processes. Rather than exhibiting directionality, the texture is random, which is beneficial in many applications. Furthermore, by taking multiple skimming passes, EDM finish quality can become almost mirror-like.

What is SPI b2 finish?

SPI b2 is slightly finer than b1 and RA.4-5 made by 400 grit. SPI b3 is comparable to RA.9-10 made by 320 grit. SPI c1 is finer than b3 and RA.10-12 made by 600 stone. SPI c2 is slightly finer than c1 and RA.25-28 made by 400 stone.

Can you wire EDM plastic?

Common Metals for Wire EDM Services. Virtually any material that is conductive is a perfect one for wire EDM, and it includes all the metals. DEK’s wire-cut EDM equipment also can machine plastic, metal alloys, exotic and precious metals.

What is difference between VM and VDI?

When looking at VDI vs VM, their difference is that a VM is a virtualized computing environment functioning as a traditional physical computer with its own CPU, memory, storage, and network interface whilst VDI, on the other hand, leverages VMs to provision and manage virtual desktops and applications.
