AP3L: Minimizes the Thermal Effect

Both dielectric and air are circulated through the machine tool.

Dielectric is used as a chiller of the drive to maintain the machine temperature.

Air is also circulated throughout the machine structure to minimize the external thermal effect, which eliminates the need of insulation cover.

Heat sources such as power supply and pump are installed separately to avoid heat transfer to cutting area.

Dielectric circulation

Heat source is separated from machine tool

Case Study with AP1L #1

• Drill a cavity of ø1.22mm with tip angle of 135º• Turn the workpiece by 180º and drill a hole of

ø0.222mm in its center

Customers application; Aerospace industry

Angle on the bottom surface: 135º

Steel

All of the cutting including electrode dressing is performed by AP1L

Case Study with AP1L #1
