Grinding a crankshaft is a process of removing material from the journals in an effort to refurbish and reuse an expensive, yet vital component of an engine. It is usually done during the process of rebuilding an engine when needed, but also has some performance aspects which come along with the process.
Crankshaft grinding is the process of grinding down the main and rod journals of crankshafts. Sometimes very expensive high performance crankshafts are damaged. People commonly discard damaged high performance crankshafts.
Accuracy, high performance, and process reliability—successful production of automobile crankshafts Hard machining of crankshafts places high demands on machines and technology. Much depends on the grinding of this central engine component as it must be performed with …
With the crankshaft straight, and the welded journal or thrust roughed in, it is now ready for the finish crankshaft grinding process. Although welding is most often used to repair damaged crankshafts, this process is also used to increase the stroke on performance crankshafts.
Crankshaft Grinding Process Step 5) Crankshaft High Pressure Wash Following these precise machining procedures, our cranks undergo a second high pressure wash cycle to guarantee the removal of any debris that may have adhered or become dislodged during the grinding process.
To further refine the crankshaft grinding process we make the most precise fit by micro-polishing the component with a 600 grit emery cloth. Through micro-polishing and industrial crankshaft grinding, we achieve the recommended Rockwell hardness and Ra finish (Roughness Parameter).
Pendulum grinding. The pendulum grinding method enables crankshafts to be rough and finish ground in a single clamping set-up. The crankshaft rotates around its central axis and the grinding wheel follows the circular motion of the pin bearing by interpolation of the workpiece spindle (C axis) with the grinding spindle (X axis).
Crankshaft grinding is not an automated process and requires a large amount of skill from the machine operator to get the job done right. Many engines have detected vibrations in them during operation, which is caused by machinists not doing the proper work needed to keep the shaft balanced once it ...
CNC crankshaft grinding machine in a process line A typical crankshaft grinder machine will begin the process using a lathe. A solid piece of cylindrical metal is placed between two wheels and the metal is then milled down to exacting specifications.
Compared to conventional grinding wheels, this results in significantly extended lifes for abrasives, in turn leading to reduced tooling-up times and tool costs. The consequence for our customers is a more economical grinding process.

Crankshaft grinding with JUNKER grinding machines. The crankshaft is the heart of any engine. By means of connecting rods, the crankshaft converts the oscillating, linear movement of the pistons into rotational movements, which then drive the engine of the car or other vehicle.
The crankshaft grinding process is a subdivision of external cylindrical plunge grinding. In this application, both the journals and pins are ground to size. The pin bearings are generally ground with a single grinding wheel.
Maintaining the crankshaft and grinding it to correct specs is one of the most important services that go into a complete engine rebuilding. But before you start the grinding process and operate your machine, there's a few tips to consider.
To further refine the crankshaft grinding process the machinist makes the most precise fit by micro-polishing the component with a 600 grit emery cloth. Through micro-polishing and industrial crankshaft grinding, the machine shop achieves the recommended Rockwell hardness and Ra …
Dec 06, 2012· Conventional grinding wheels in aluminium oxide or vitrified CBN grinding wheels are used. An essential part of every crankshaft grinding process is checking the shaft's dynamic balance. Category
