High-accuracy taper machining
using round dies
●
Highly accurate machining of extremely small tapered
sections is realized
●
Uniform die edge land cuts are possible
●
Angle Master Function realizes highly accurate machining of
large tapered sections
●
Insulated worktable ensures improved surface finishing
●
Stable machining realized when using short-pulse and
low-voltage machining conditions

●
Flow analysis simulation was used to optimize the water
flow through the guide, enhancing cutting speed by
improving sludge removal from the gap
High-speed digital control
●
Spark detection speed (up to twice as fast as our
conventional model) provides improved discharge
efficiency and suppresses wire breakage simultaneously
