Standards of TT-DN50 Coplanar Double Notch Machine
- GB/T18743.2-2022, ISO 21304-2, ISO 21304-2, ISO 9854,
ISO 16770-2004, ASTM F 1473
Features of TT-DN50 Coplanar Double Notch Machine
- May accomplish the preparation of two sides of the coplanar notch in one time.
- The unique structure design makes the notches and specimen centerline strictly coincident.
- The electronic micrometer is used for measuring the notching depth, largely guarantees the accuracy and consistency of both remaining width of the specimen.
- Double knives cutting & double knives synchronization: in the notching process, the cutting force on both sides of the specimen is same, and the deformation at radial direction is invisible.
- The knife blade is only subject to axial force without any lateral force, which largely increases the knife lifetime.
