May 15, 2017 Cam grinding machines are typically equipped with a rocker ball mechanism. This allows the work to move toward and away from the wheel with each revolution of the grinding wheel. The work supporting centers and the steady rest are mounted on the rocker bar and the rocking motion allows creation of the cam

Oct 26, 2016 Lots of cooling fluid is used to keep the stone and the cam cool during the process. It moves very quickly. The lathe uses a follower cam, much like the camshaft in your car, except that on the machine, the cam lobe rotates against a solid lug. The cam lobe moves the spinning camshaft, changing its position against the spinning grinding

The camshaft or cam profile grinding process is a special form of external cylindrical plunge grinding between centres, in which the grinding wheel axis machines the cam profile in a contour-controlled manner. As a result of the extremely high cutting volumes required, vitrified bonded CBN grinding wheels are mainly used today, particularly in ...

CAMSHAFT: A shaft with one or more cams attached to it, e.g. working of valves in an internal combustion engine is controlled by camshaft. Cam shaft is called the “brain” of the engine. CAM TERMINOLOGY Base Circle: The smallest circle centered on the cam rotation axis, and tangent to the cam surface. The size of the base circle is

Nov 11, 2011 Mr. Godbold explains that Comp Cams’ traditional expertise was in grinding camshafts, not machining them. So when the decision was made to install the seven-axis multifunction lathe in 2008, the company relied heavily on the expertise and advice of its equipment suppliers to establish an effective machining process.

Customarily with late-model crankshafts, says Heidbreder, rebuilders mic the journals and go through a two-step polishing process. "If the crankshaft is salvageable and you don’t have to grind it, you polish it with a #400 grit aluminum oxide polishing belt.

GRINDING PROCESS Grinding machines for grinding camshafts, cam pieces and individual cams combine non-cylindrical grinding for the cams and cylindrical grinding for the bearings. With non-cylindrical OD/ID grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis).

In the process, each angle is assigned a lift value to define the cam contour and import it to the program. The software then interpolates the values automatically. The cam contour is frequently concave in the infeed and discharge area. Here the concave radius determines the maximum grinding wheel diameter that can be used.

Read MoreDuring the remanufacturing process the machinist is mostly concerned with grinding the rod and main journals. Upon initial inspection of the crankshaft, with the use of the micrometer, the machinist will determine what bearings need grinding. Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch.
