Good News for Shipping Companies, Power Plants and Repair Workshops.
Crankshaft grinding machine up to 700 mm diameter is designed, developed and manufactured by RA Power Solutions. Machine is having following features:
Crankshaft Grinding Machine Design: Machine is portable; light weight and can be carried to the site. Nowadays, there is no need of disassembly of complete engine.
Operation of Crankshaft grinding machine: The machine is operated pneumatically or by electrical motor. The design is so simple and machine can be easily operated by a skilled technician.
Quality:Crankshaft grinding machine is capable of maintaining close tolerance in terms of taper and ovality up to 20 microns and can also achieve the surface finish as per the International standards.
Training: RA Power Solutions Pvt. Ltd. provides training to the clients, technicians for the duration of 3 days. The assembly, operation and maintenance of the machine are explained.
Cost of Machine: Presently, shipping companies, power plants having high capacity diesel generating sets have no option but to call for the technicians from the companies based in Norway, Singapore, UK and various countries by paying exorbitant amount and travel expenses. The Crankshaft grinding machine is manufactured by RA Power Solutions is very reasonably priced and the cost can be recovered in 1 or 2 jobs of repairs.
Crankshaft grinding and polishing is an important activity which is required after running of engine for a long time as due wear and tear taper and ovality is created. Again in case of failure of bearing grinding and polishing of crankshaft is required. In olden times it was necessary to remove the crankshaft from the block and send it to the designated workshop for grinding and polishing.
The removal of crankshaft from the block involved disassembly of complete engine, packing and transportation to the workshop resulting to high down time and expensive. RA Power Solutions has developed, design and manufactured on site crankshaft grinding machine which can undertake grinding of crank pins or journals up to the diameter of 700 mm. The machine is capable of maintaining the tolerance within 0.02 mm in terms of taper and ovality. It is very easy to operate and needs minimum training.
The machine is light in weight can be taken to the site. The machine is in two parts and can be inserted in the engine block through the inspection window facilitating grinding of CR Pin without removal of crankshaft. The grinding and polishing is undertaken by same machine. RA Power Solutions suggest to polish and grind if necessary the crankshaft whenever it is open for major overhauling. This will considerably enhance the life of crankshaft, bearing and engine. The machine gets drive from a pneumatic turbine which is again light weight. The drive is also given by a electrical motor where the air supply is not available. The assembly of the machine and its operation can be seen on a YouTube channel
