  • Things to Know About Cam Grinding AutoBeat

    Grinding of re-entry type cam profiles with grinding wheel requires that smaller diameter wheels be used. This restricts the life of the wheel, making its use less cost-effective. With abrasive belts, the curvature of the belt can be controlled by changing the contact shoe diameter, so re-entry lobes of high negative curvature can be easily ground.

  • More Effective Camshaft Machining : Modern Machine Shop

    Nov 11, 2011· That’s because the camshaft’s nine journals provided more clamping points for the subspindle than a typical five-journal camshaft. Consequently, the original subspindle jaws were not long enough to clamp across at least two journals on the five-journal models (this was necessary to ensure adequate support during machining).

  • A Model Camshaft Grinding Process : Modern Machine Shop
    Problematic ProfilesParameter InputTelling TemperaturesBridging Engineering DisciplinesCamshaft lobe grinding presents processing difficulties not found in concentric grinding operations. The contact area between the wheel and lobe (known as arc of contact) is continuously changing as the wheel passes around the perimeter of the lobe. Contact area is greatest in the relatively flat flank area, versus a camshaft’s more rounded base circle and nose. For that reason, it is in the flank areas that burning is most likely to occur, and where many manufacturers slow the work speed to...

    The camshaft can then be lowered into the block straight down, so there's minimal effort needed to assure that the cam lobes and cam journals DO NOT nick the bearings. If the cam MUST be installed horizontally, it is mandatory to use a "handle" of some sort on the front of the cam, and to take particular care that the cam doesn't bang into, or

  • Grinding (abrasive cutting) Wikipedia

    Grinding is a subset of cutting, as grinding is a true metal-cutting process. Each grain of abrasive functions as a microscopic single-point cutting edge (although of high negative rake angle ), and shears a tiny chip that is analogous to what would conventionally be called a "cut" chip (turning, milling, drilling, tapping, etc.). However

  • How are crankshaft crankpin journals ground?

    The grinding stone in the back is then spun up to speed and is then brought into contact with the journal face. As material is removed through the grinding process, the machinist pays attention to how much is removed, then stops the process once just shy of the finished dimensions. Each journal in turn is ground in the same manner.
