Assembly & alignment checking of the Engine block with crankshafts

Metal Stitching

home_serv-metalstitchingimg
Metal stitching is a commercial method of repairing the crack, broken, or burst pieces of cast iron items without application of any heat & as a result of whichthere is no change/distortion/deformation in the repaired equipment. In the repairing process Locks & Cast master, stitching pins are used. We Import the materials from the USA.
Advantages of Metal Stitching
No heat stresses are induced, no distortion occurs. The repair is Gas & Liquid proof & can withstand high pressure & tensional forces & not much machining is required after repairing.

Line Boring of Equipments

home_serv-lineboringimg
Line Boring of Engine Blocks, Bed Plates, compressor blocks, and gearbox blocks are undertaken by us. We are capable of machine two or more bores in a line up to the length of 10 meters with an accuracy level of 0.02mm. We have imported the hydraulic/pneumatic Line Boring equipment which is used for line boring operation. To check the alignment of Bores, an Easy-Laser alignment checking equipment is imported from Sweden, is used. With this laser equipment, alignment of housing bores along “X” & “Y” axis with an accuracy of 0.01 mm can be checked .

Boring and Honing of Cylinder Liners

Boring and Honing of Cylinder Liners-feature
The Cylinder Liner boring and Honing is carried out with the machine which is imported by us from a world’s leading company -M/S Chris Marine, Sweden who masters the art of manufacturing of high quality Cylinder Liner boring/honing equipment. The limit of accuracy of re-honed Liners is maintained within 0.02-0.03 mm for taper/ovality and the surface finish is controlled within RA1.3-1.6 um along with yar cross-honing angle is maintained within 45-55 Deg. The machine is portable, so we can undertake the Fas honing operation at the customer’s location also.

NDT Testing of Engine Components

home_ndtimg1-new
NDT inspection of the Crank shafts , Engine Blocks , Con Rods , Liners , Cylinder heads , Camshafts & other Engine parts are carried out by the specialized trained Engineers who are level II & III grade . etc. . Each Job Inspection is conducted by Engineers who are fully trained and have work experience more than 15 to 20 years in all kinds of inspection work including Magnetic Particle, Ultrasonic, and Dye Penetrant Tests along with Dimensional measurements with highly precise instruments like Laser Equipment, Micrometres, Bore gauges, Dial gauges, Digital verniers, etc which are periodically calibrated as a routine practice for the authenticity of accuracy. A key Management person implements regulates and reviews all quality aspects and production standards .

Rebuilding of the crankshafts & other components

Re-building-under-Process
The Rebuilding of the Crankshaft is required when the damage/cracks in the CR pins / MJ are high level & with the available undersize bearings, the repairing could not be possible & the crankshafts stands rejected. To salvage the crankshaft the rebuilding is the only solution which is undertaken by us in a fully computerized imported equipment. This rebuilding is a “cold” process & at any moment of the repairing process the crankshaft temp doesn’t cross 90 degrees C, so no stress is induced in the crankshaft. Also, this rebuilding technology is used where no under-sizing of the shafts are allowed such as Alternator Rotors shaft or the shafts which use Roller bearings. We stand a warrantee of around one year on the rebuild area which is carried out by us.

Connecting – Rod Housing Repair

Connecting - Rod Housing Repair-feature
The company has developed technology to salvage expensive ConRods housings by repairing them in-house for correction of the ovality which develops in operation. Crack testing is done to determine invisible cracks & correction of the dimensional wear.
In-housing Bore is done & during this process straightness, Parallelism, and center distance are maintained as per OEM STD during the repairing process so that the accuracy of the repair and finish is achieved as per OEM specifications/tolerances.
