The mould halves, which weigh up to 70 kg, are attached to two zero-point clamping systems of different sizes (IST 148 and UPC 320) and furnished with RFID chips. A robot scans the workpiece chip and forwards the data to the process control system. “The equipment then knows the sequence of process steps, for example, milling followed by cleaning and measuring, and then erosion, again followed by cleaning and measuring,” Ostrovski says.

Vacuum drying achieves better efficiency

After machining or die-sink EDM, the machine removes the workpiece, brings the clamped mould halves to the cleaning cell and secures them to the process chamber’s rotary mounting, which is laid out for both zero-point clamping systems. The rotating workpiece is then sprayed with a neutral cleaning agent at a temperature of 40° C and a pressure of 10 bar.

Cooling coils in the rinsing medium tank maintain a constant temperature of 21°C. The work pieces are dried with hot air, and then vacuum dried. The latter has two effects. “We draw all residual moisture out of the workpiece and heat the parts up to the required temperature at the same time,” says Ostrovski. Afterwards, the robot delivers the work piece directly to the measuring station. “We run this line seven days a week, 24 hours a day, and cleaning functions flawlessly,” Ostrovski concludes.
