Quality Control

QUALITY CONTROL PROCESS OF DISC BLADES -


Chemical Composition Testing:-
Raw material plays the most vital role in achieving the mechanical properties desired. We at USD inspect a sample lot of raw material before ordering the required quantity. Dedicated lab Technicians keep a close check on the composition of different steel grades.

 

Hardness Testing:-
It measures whether the hardness achieved is within the prescribed range or not. Different grades of steel give different hardness levels. It signifies the strength and toughness of the disc.


Wobble Testing:-
This is done to make sure that there is no axial deviation of points on disc edge in a plain, parallel to the axis of the disc when the disc is rotated about its center.


Eccentricity Test:-
This test enables us to identify radial deviation of points on the disc edge in a plain perpendicular to the axis of disc when rotated about its center.

 

Basic Dimentional Test Includes:-


  • Normal Size
  • Thickness
  • Center hole
  • Concavity
  • Fixing hole
  • PCD
  • Bevel Length
  • Bevel Angle

 

Crack Test and Visual Testing:-The test helps to identify the location of any flaws such as surface cracks, scales, pits, nicks and burns etc. on this disc.
