Fast replacing fixture for EDM Die Sinker

Fast replacing fixture system for the edm die sinker

The copper electrode is the key part for the electric discharge machining,that’s used to process the mold cavity.so the quality and efficiency of producing copper electrode will affect the mold’s quality directly.

 General fixture and jaw vice apply to clamp the machining electrode,that’s the traditional way. It’s 4 minutes for clamping the single electrode.and the engineers still need to spend time installing electrodes and calibrating on the edm machine.those affect the working efficiency seriously,but the fast replacing fixture can be used for clamping multiple copper electrodes one time,One a minute, it can clamp ten electrodes for ten minutes.

 The characteristics of fast replacing fixture:

1. precise positioning and less error,There are one mode with multiple cavities of most of the plastic molds.the precision,roughness and complexity have improved much more than before,It’s very common for multiple electrodes of the electric discharge machining at present.that’s need the less error and precision position to machine the plastic mold.
2. Improving the efficiency of the edm die sinker,nc machine has processed the copper electrode in the holder,then the electrode has not taken down from the holder,that can be installed on the edm machine to work,So the fast replacing electrode holder clamp can reduce the installing electrode time,and not calibrate the position.

   Time of cutting copper electrodes

Traditional clamping	time	Fast replacing jig	time
Edm installing	10 minutes	Edm installing	5 minutes
Per-installation fellow up	10 minutes	Per-installation fellow up	10 seconds
Single processing	20 minutes	Single processing	180 minutes/9 pic
Per-processing	1-4 pieces	Pre -processing	More 9 pieces
production	2 electrodes/hour	production	4 electrodes/hour

Copper electrode discharging time

Traditional edm	time	Fast replacing jig	time
Work-piece installing	5 minutes	Work-piece installing	5 minutes
Per electrode installing	15 minutes	Per electrode installing	10 seconds
Per working	10 minutes	Per working	10 minutes
production	2 pieces/hour	production	4 pieces/hour

• Lower the cost,high efficiency,high quality and less error can reduce the time and labor costs effectively.two days of work in one day.the copper electrodes with holders can be used repeatedly and inspected by the three-dimensional.

  The fast replacing electrode fixture system mainly apply to the CNC machining,inspection,and electric discharge machining and wire edm.used for automobile,military industry, electronics and plastic molds production.
