|
|
|
Main
features |
|
|
· Sintering machine suitable for the
production of average and large size segment series, continuous rim blades,
grinding wheels for glass and other diamond tools. |
|
|
· Mould heating system for direct
passing of direct current (Joule effect). |
|
|
· Sintering with steel and graphite
moulds. |
|
|
· Sintering under controlled
atmosphere by means of vacuum/inert gas
programmable wash. |
|
|
· Type K thermo-couple for operating
temperatures up to 1000°C. |
|
|
· Plates cooling, transformer and vacuum
chamber with flow visualisation and water temperature. |
|
|
· 120kVA three-phase transformer, (max.
power supply is limited electronically to 210A) by switch for 3 different
tensions between the electrodes(maximum power limit for heating). |
