Rigid Linear Motor Drives

The AL40G is equipped with in-house developed and manufactured Rigid Linear Motor Drives that allow high-speed and high response machining. Axis acceleration up to 1G enables stable machining even in the most difficult “no flush” cutting conditions.

Newly Developed SP Power Supply

The communication and processing speed has been improved further in the newly developed “SP Power Supply” , increasing motor response speed by almost double. The adaptation of the new “TMM4” and “BSN4” circuits improves the quality and speed across the entire discharge machining range.

“Arc-less 4” Circuit

The adoption of the latest electrical discharge control technology “Arc-less 4” circuit greatly improves the performance of the AL40G in terms of electrode wear, speed and surface finish.

New Discharge Circuits

New discharge control circuits TMM4, TPC4 and BSN4 are provided standard on the AL40G ensuring machining quality and speed are improved across all EDM processes. Short pulse high peak current ensures speed improvement throughout finishing cycles even in narrow gap applications.

Thermal Commit (TH COM)

Through sensing, the temperature of each component of the machine is precisely corrected and the Thermal Commit (TH COM) function, which provides various diagnostic functions, minimizes thermal displacement due to temperature changes in the installation environment and during high-speed driving.
