With the introduction of the Onsite Crankshaft Grinding Machine, Insitu Crankshaft Polishing and Grinding Machine, and Crankshaft Machining, there is no need to remove the Crankshaft and send it to the workshop, as now it is possible to undertake crankshaft grinding and crankshaft repair with the revolutionary design of Onsite Crankshaft Grinding Machines.
Onsite Crankshaft Grinding Without Removal Using Radius Fillet Reference
The onsite crankshaft grinding machine is placed on both sides of the radius of the crankpin, and the tool rotates, undertaking grinding and polishing of the crankshaft. This process of crankshaft grinding by insitu crankshaft grinding machine is generally for the diameter of the crankpin of 200 mm and above, having a bearing width of 125 mm minimum.
.
For the smaller diameter of the crankpin, it is not possible to undertake the grinding by taking the reference of radius fillet due to the space constraints.
RA Power Solutions has introduced a compact, easy-to-operate onsite crankshaft grinding machine, which is suitable for grinding and polishing of small diameters of the crankpin above 30 mm. The crankpin bearing width can be as small as 30 to 40 mm. With this latest technological advance crankshaft grinding machine, it is easy to grind the smaller diameter of the crankpin having a smaller crankpin bearing width.
The crankshaft grinding machine has the main features of machining, grinding and polishing of the crankpin. The tolerances in terms of taper, ovality, and surface finish are maintained far better than the manufacturer’s recommendation.
RA Power Solutions, having 4 decades of experience in in situ crankshaft grinding have executed the repair of more than 21,000 crankshafts all over the world and is a leader in this field.
