Productivity

At precision and finishing operations of geometry generation the electrochemical machine working with ET-technology, allows to receive a part in 10... 100 times faster, than machines of competing technologies (for example, electrolytic erosion and multiaxis high-speed milling).

Here are some examples to compare productivity of ECM and EDM operations.

Example 1. Machining of a demo die (The arms of Russia)

Machining methode	EDM	pECM
Part and tool overview
Machining area	40 cm²	33 cm²
Premachining	no	no
Material	steel	Stainless steel
Surface roughness, Ra	0,08-0,15 um	0,15 um
Required tool number	1	1
Tool wear	small	no
Tool material	copper	Stainless steel
Machining time	4,5 hours (including 1,5 hours polishing )	0,5 hours

Example 2.Machining of dies and molds

Machining method	EDM	pECM
Part and tool overview
Machining area	104 cm²	80 cm²
Premachining	1 mm (stock after prlimenary milling)	1 mm

Surface roughness, Ra	0,15 um	0,08 um
Required tool number	2	1
Tool wear	small	no
