Chemical composition
Sample lots are inspected before the required raw material quantity is ordered.
Quality assurance
Tested at every stage.
Manufacturing process
Control begins with the steel.
High carbon steel, chrome steel and micro-alloy boron steel are primarily used to manufacture agricultural disc blades. Because discs work in abrasive soil conditions, raw material selection is essential to optimum output.
Cutting
Steel sheet is accurately cut into a round disc blank.
Bending
The round sheet is formed using different dies for different disc sizes and concavities.
Shot blasting
Automatic shot blasting improves surface finish and supports greater fatigue life.

Inspection plan
Checks that protect field performance.
Dedicated technicians monitor chemical, mechanical, dimensional and visual attributes across production.
Hardness testing
Confirms that achieved hardness is within the prescribed range for strength and toughness.
Wobble testing
Checks axial deviation of points on the disc edge as the disc rotates about its centre.
Eccentricity testing
Identifies radial deviation of edge points perpendicular to the disc axis.
Dimensional testing
Verifies size, thickness, centre hole, concavity, fixing holes, PCD, bevel length and angle.
Crack & visual testing
Identifies surface cracks, scales, pits, nicks, burns and other visible flaws.
