The DM series of rotary tables are completely waterproof and are designed for EDM applications.
They are built from stainless steel and can be completely submerged.
The DME100 table has a Fanuc absolute encoder to improve precision and is only available as a 4th axis.
The DM100 is available with a Kitagawa controller or with a suitable motor to interface with a machine that has already been prepared for an additional rotary axis.
Both rotary tables are compact and high precision and will greatly expand the capability of a spark or wire erosion machine.
These rotary tables are available with specially designed submersible chucks and tailstocks.
RAV specification comes with an external controller that functions off an M-Code, used for machines that do not have 4th axis preparation.
