Crankshaft Machining

We have specialization in rebuilding and repairing the crank shafts, cylindrical shaft, castings and mechanical components, which are damaged and worn out beyond the last permissible limit. We are renowned for repairing manufacturing errors, to repair an obsolete part or a part that has worn excessively. The reclamation of crankshaft (and many other components) can produce considerable saving over the replacement cost, wherein saving of 50% is common and in case of large components, as much as 90% can be saved. Our trained engineers work on site and in the factory to provide highest quality of rebuilding techniques. This helps us to achieve high specification irrespective of all types of components with the assistance of latest equipment.

General Applications:

• Repair and Reconditioning
• Erosion preventing coating
• Anti-Corrosion
• Heat Shield
• Erosion Prevention
• Insulation
  

Deposit materials mainly used are:

• Steel
• Tungsten Carbide
• Chrome Carbide
• Ceramics and Plastic Composite
  

Our Techniques are as follows:

• Flame Spraying
• Plasma Spraying
• High Velocity Oxygen Fuel
• Arc Spraying
• Thermal spraying
  

Advantages:

• Rebuilding provides a smooth, wear - resistant surface with a low co-efficient of friction
• Especially for crankshafts which require a hard surface on the crankpins and main journals, thermal spraying is the best build-up method
• It is a "Cold" process, the risk of heat warp age by welding and the need for subsequent straightening is eliminated
• A prime financial benefit of this application is in saving the replacement cost of the components and in some cases, saving the replacement cost of the engine itself, when new parts are not obtainable
• Depending on the local cost of labour, the cost of repairing of the crankshaft will vary. But having repaired so many crankshafts our experience shows that replacement cost of components is very economical.
