Onsite Crankshaft Grinding Machine

About Onsite Crankshaft Grinding Machine

For satisfactory running and performance of diesel engine or any rotary equipment, it is important that crankshaft is periodically checked dimensionally and for other important parameters. For any correction and repair required in crankpin and main journal diameter of the crankshaft, crankshaft grinding and polishing machine is required.

Necessity for Onsite Crankshaft Grinding and Polishing Machine

It is observed that after continuous running of engine and crankshaft, it is important that during the major overhaul of the engine crankshaft is inspected for the following main parameters:

I) To check taper and ovality of crankpin/main journal diameter

II) To check the surface finish of crankpin/main journal

III) Inspection of hardness and presence of crack

Change of Technology - In situ Crankshaft Grinding & Polishing Machine

In olden times invariably bench type crankshaft grinding machine was used. These machines were installed in a workshop and it was necessary to disassemble the engine, remove the crankshaft, pack and transport it to the designated workshop. This is now outdated.

The change in technology has been taken place, the heavy duty expensive bench type crankshaft grinding machines are replaced by portable, light weight, easy to operate in situ crankshaft grinding and polishing machine. There is no requirement of removal of crankshaft from the engine block as the crankpin/main journal grinding and polishing can be done onsite. The machine is inserted from the inspection window.

Main Features of Revolutionary Onsite Crankshaft Grinding and Polishing Machine

I) Excellent on site grinding equipment replacing the outdated heavy duty bench type crankshaft grinding machine.

II) Onsite Crankshaft grinding and polishing machine is portable and can be easily carried on board a vessel, power plant or any installation all over the world.

III) Easy to operate and easy to maintain.

IV) Onsite crankshaft grinding and polishing machine is designed to deliver close tolerances in terms of taper and ovality, surface finish, runout and all parameters as per manufacturer specifications and tolerance.

We are an ISO certified company and all the quality control norms are strictly followed during the manufacturing of the machine.

Main body of the machine is manufactured out of titanium steel which has the inherent quality of absorbing the vibrations. This facilitates to undertake grinding and polishing of crankshaft even while sailing of the vessel. Every part is subject to stringent inspection and metallurgical properties are improved from time to time based on the field trails and reports.
