Why Molybdenum Wires Break in the Wire Cutting Process?

1. Molybdenum Wire of Wire Cutting

1.1 The quality.

1.2 Losing too much or the service life is expired. 

1.3 The tension is too tight or loose.

1.4 Broken wire interference.

2. Wire Mechanism of Wire Cutting Machine

2.1 Conductive block has grooves, which will break the moly wire.

2.2 The precision of guide wheel affects the stability of discharge machining of moly wire.

2.3 Sudden change of tension in the cutting process of moly wire caused by the radial runout of wire storage cylinder.

2.4 The winding of moly wire in the storage cylinder is unreasonable.

2.5 Molybdenum wire is not placed in the guide pulley groove. 

3. Cutting Technology Parameters

3.1 Unreasonable cutting technology parameters. 

3.2 The path of machining programming path of working piece is unreasonable. 

3.3 Wire breakage caused by secondary cutting.
