Since parts come with higher tolerances year after year, spark erosion is required increasingly. Hittech Bihca has expanded its capacity from 3 machines to 6 machines at present.

The latest spark eroding machine is the AgieCharmilles Cut 2000 S. The main reason for investing in this machine is to reach a low Ra value on titanium parts. Results are currently Ra 0,20 on titanium. On hard metal the machine is capable of Ra 0,07.
