Quality and Processes

Cross Rolling Process
Disc blades made out of Cross-rolled sheets are stronger, tougher and have much lesser wear and tear. Cross rolling ensures optimum mixing of grains in the raw material, thus imparting suitable properties.

Cutting Process
This is the process in which sheet is cutted round in a shape of disc.

Bending Process
This is a process in which the round sheet is bended to form a disc in different die & diffrent sizes.

Shot Blasing
Shot blasting of the disc blades increases the fatigue life of the disc blade. Due to automatic shot blasting, high quality surface finish disc blades are manufactured.

Stage Testing at each point is an integral part of the manufacturing process at KSI.

Stage Testing Includes

• 
  Chemical Composition Testing
  Raw Material plays the most vital role in achieving the mechanical properties desired. We at KSI 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 measurers 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 centre.
• 
  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 centre.
• Basic Dimentional test includes :-
  
  

  Normal Size	Thickness	Centre 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 the disc.

Materials
High Carbon Steel , Chrome steel and Micro Alloy Boron Steel are primarly used to manufacture agricultural disc blades. The very abrassive nature of disc in different soil conditions makes the raw material selection process a very important parameter for optimum output.
