Manufacturing Process


Manufacturing Process for Taper Roller

Cold Forging
  • Favorable crystal grain flow increases toughness.
  • Near net shape Rollers.
Tumbling
  • Removes sharp edges and surface scale.
  • Free from dust and sludge.
Heat treatment
  • Increases the strength and resistance to wear.
  • Removes the internal stresses.
Shot blasting
  • Provides a consistent and uniform surface.
  • Free from dust, sludge and heat-treatment scale.
Outer diameter rough grinding
  • Reaches close to final dimension and tolerance.
  • Becomes easy to achieve final tolerance.
Large end face grinding
  • Generates the perfect large end face radius and roughness.
  • Achieves the final tolerance.
Outer diameter finish grinding
  • Extremely high dimensional accuracy and shape accuracy.
  • Low waviness and surface roughness as well as excellent friction properties of the ground surface.
Outer diameter super finishing
  • Improves roughness, roundness and the load bearing capacity as well as reduces running noise.
Inspection
  • Visual and dimensionally checking to assure defect free Rollers.
Packing
  • Rollers are packed in pelletize carton boxes after rust preventive oiling.
  • Packing is also done as per customer requirement.
Shipment
  • Transportation as per customer requirement with proper care of goods.
