We here at NASS Engineering Services Pvt Ltd are experts at grinding diesel engine crankshafts. Crankshaft grinding consists of removing a minute amount of finished material from the rod and main journals to rebuild the part back to OEM spec. The full crankshaft remanufacturing process is quite intensive but is critical to complete engine rebuild.
Engine Block Line Boring
Line boring is a very important task, but it is also one that takes the right equipment and the right talent. In many situations, these are simple applications, but in others, they can be very complex requiring a special level of skill. This is especially true in situations where custom solutions are necessary. And at NASS Engineering Services Pvt Ltd will provide you with the right equipment and the right talent required for carrying out the engine block line boring.

In Situ Liner Honing
Periodical honing can minimize operational cost and increase the service life of cylinder liners and piston rings. For reducing blow by and scuffing as well as lube oil consumption, it is highly recommended to honing the running surface of liner regularly. And we at NASS Engineering Services Pvt Ltd provide you with the provision of in situ liner honing with special tools.
Laser alignment and Vibration analysis
Condition monitoring is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance. The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent consequential damages and avoid its consequences. Condition monitoring has a unique benefit in that conditions that would shorten normal lifespan can be addressed before they develop into a major failure. Condition monitoring techniques are normally used on rotating equipment, auxiliary systems and other machinery (compressors, pumps, electric motors, internal combustion engines, presses).
We here at NASS Engineering Services Pvt Ltd provide with two condition monitoring techniques i.e. Laser Alignment and Vibration Analysis.

Dye Penetrant (DP) Test and Magnetic Particle Inspection (MPI)
Magnetic particle inspection is often carried out to help determine an item’s fitness for use or conformity. The method can detect surface or near-surface flaws such as cracks, laps, seams and inclusions in ferromagnetic materials such as iron and steel. One of the main advantages of magnetic particle inspection is that it can give an immediate indication of defects and discontinuities.
We at NASS Engineering Service Pvt Ltd offers best service in Dye Penetrant (DP) Test and Magnetic Particle Inspection (MPI) for various engine components, propeller shafts and blades, etc.
