Charpy/Izod Specimen Automatic Notching Machine / Notching Tool™ | 628-A-4/A-4E

(Advanced milling type notcher for Izod/Charpy/Tensile-impact test specimen)

The Notching Tool A-4 series are miniature, computerized numerically controlled milling machine for preparing a variety of notched specimen bars.

All operations except mounting and dismounting of the specimens are automatic.

Features & Benefits

• It automatically positions and cuts according to specimen and notch dimensions.

• The instrument employs a precision servo motor control system with a touchscreen control display.

• Safety interfaces protect the operator from accidents.

• The cutter speed and table travel speed can be optimized for the specimen’s material.

• The instrument can store up to 99 (16 for A-4E) user-defined cutting programs.

• Bars can also be automatically cut from the ISO multipurpose specimens (A-4 only).

• Compact design with a width of approximately 30cm allows for effective use of workbench space.
