TEK4

EDM, LASER, STEM Drilling

The Next Generation...

EDM Network and TEK4 from England, have teamed up to introduce the latest Tek4 Aerospace and IGT Machining products to the North American market.


Tek4 produces a self contained STEM drilling machine that can ECM Drill very deep holes using a very high amperage (1000 amps max) power supply and a coated Copper tube and using a diluted Nitric Acid Dielectric to Drill very deep holes in metals that are almost impossible to machine conventionally. The process can drill these small and deep holes, very quickly. Plus, multiple holes can be Drilled simultaneously. Typical hole diameters of 1-2 millimeters through 12-18” depths are possible. Plus this is done with virtually no recast later on the Drilled surface and almost no electrode wear.

TEK4 EDM LASER STEM Drilling

In addition to the STEM Driller, they offer 6 Axis EDM small hole drilling including 3D Shape Machining to EDM Drill, and then 3Dshape machine details like diffusers on the “hot section” parts in a jet engine or gas turbine. These diffuser shapes and holes are used to cool these parts, as the heat in these sections is near the melting point of the metals used.


In addition to the drilling and shape Machining, We offer an optional Laser Ablation accessory that can laser cut the Ceramic coating that is used on some of these parts, before the EDM drilling operation. These two features are installed on the SAME machine so that both operations can be performed in one set up so that the position of the start hole is as close as possible to the edge of the ceramic for optimum protection of the coated surfaces.


In addition, full part, and fixture probing utilizing precision Renishaw probes, are included as standard features on the 6 Axis Drillers. Plus, all of the probed data, as well as all of the cutting data, settings, Drill time, breakthrough depths, etc, are all stored by the part number and can be sent to the server via the LAN connection to archive for later, all as a standard feature!

The last new Tek4 product is their full laser drilling system utilizing an articulated laser head to laser drill very small holes in large aerospace and IGT parts, very quickly! As with the 6 Axis Drillers, full fixture and part programming using the Renishaw probes, are included as standard features.
