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.
Air circulation
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
Workpiece
Electrode (CuW)
CuW block for dressing ø1.2mm electrode
CuW block for forming angle of 135º
Ø1.5mm electrode is dressed down to Ø1.2mm (length= 20mm) with Copper Tungsten block
After that, angle of 135º is formed on the electrode tip with CuW block in the front
Total dressing time= 19min, with spindle of 1400rpm
Step #1: Drill the cavity of ø1.22mm with tip angle of 135º
Cutting time: 2h 10min (12holes)
