A new generation STEM (Shaped Tube Electro-chemical Machining) system that overcomes the negative aspects of the process. This system is single unit machining centre enclosing the process and the acid system in a single unit. This means that the machine is easy to install and there are no acid leaks because all the tanks, pipework, filters, pumps and valves are enclosed within the machine.


The TEK4 eSTEM incorporates many new features including advanced process control and better acid control. The control system has advanced process monitoring and graphing capabilities enabling process fingerprinting and tighter control of process variables.


The TEK4 eSTEM machine is entirely constructed from stainless steel for easy maintenance and longevity.
