Electro chemical machining EMAG ECM/PECM
ECM -- Electro-Chemical Machining is the generic term for a variety of electro-chemical operations. The acronym ECM indicates that workpieces are machined by electrolytically dissolving metal. The process is used in aerospace engineering and the automotive, medical equipment, micro system and power supply industries. It can be applied to all kinds of metal -- even high-alloy materials, such as nickel- and titanium- based ones -- and also to hardened materials. None of the disadvantages experienced with conventional machining methods -- e.g. tool wear, mechanical stresses, micro-fissures caused by heat transfers, surface oxidation or the need for subsequent deburring operations -- are present in this process, as it is a contactless procedure with no heat input. All electro-chemical machining processes are characterised by internally stress-free stock removal, gentle transitions and smooth surfaces without burr formation.
On the ECM Standard Machining System “BI smart” the operator loads and removes the workpieces from the ECM unit by hand. A two-handed control button activates the ECM (electro-chemical machining) process that carries out the deburring operation.
The machine is made of stainless-steel and plastic with a manual workstation of ergonomic design forms a solid basis, equipped standard with:
- Operator-friendly Siemens control S7-300 with graphic panel
- Current relay and voltage monitor
- pH-value control and conductance monitor
- Temperature control
- Two-handed control button operation
- Optional equipment on request
