Video: Dual-Wheel, Vertical Grinding of a Camshaft

In this video, one of EMAG's VTC machines grinds a camshaft using two opposing grinding wheels. Opposing the wheels in such a way cancels axial forces on the camshaft.

Emag (Farmington Hills, Michigan) is applying the vertical grinding concept in a new way for long workpieces such as automotive camshafts. The concept uses dual, opposing grinding wheels that cut simultaneously. The prime advantage is that the axial forces created by the wheels are directed toward each other, so they are canceled.

Video of the company’s VTC machine grinding a camshaft shows the two grinding spindles moving in X and Z axes on independent, compound slides as they complete camshaft lobes. Located vertically between the two spindles, the camshaft is secured from below by a fixed tailstock center and from above by a moveable work-head center. This provides the wheels with ample access to the workpiece to allow simultaneous grinding from both the left and the right sides.

  • More Effective Camshaft Machining

    A leading manufacturer of high-performance valve train components installed a twin spindle/twin-turret lathe to bring camshaft machining work in-house. Here, the company explains how it has become more effective using its multifunction lathe to produce small batches of custom racing camshafts.

    Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly reduce the number of requisite test grinds.
