With non-cylindrical grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis). CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life. The cam geometry is specified in a elevation table.

May 22, 2008· I would like to obtain an original or a photocopy of the book "Cam and Shape Grinding with Norton Cam Grinders" by C. J. Green, published by the Norton Company. I have tried all of the book searches available to me via the web and the local public library without success. The Norton factory library does not hold a copy.
Jun 22, 2007· The grinding head was off a large toolpost grinder and gave a very good finish to the cams. I had no problems with this and there are still quite a few vintage and classic racing bikes out there that have lapped the Isle of man TT circuit ot over 100 mph with cams in from this machine.
Cylindrical grinding was developed to achieve a perfectly round shape. Out-of-round grinding, however, gives the workpiece a defined non-circular shape, with the grinding process perfecting the final surface quality. Examples of non-circular shaft-type components include camshafts, cam …

Cylindrical margins, in some materials, tend to overheat the cutting edges through friction with the work piece. Overheating the cutting edges can lead to annealing and spalling – chipping or flaking away, of the cutting edge. Cam Relief grinding offers the option of producing cylindrical margins, while conventional cutter sharpening does not.
Finish grinding the mandrel will provide you with basic experience in cylindrical grinding. Refer to a working sketch (Figure L-130) to determine the required dimensions. Selecting the Wheel For a hardened steel mandrel, the best abrasive will be aluminum oxide of 60 grit and a J-bond hardness with a somewhat dense structure.
The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.
grinding operation is followed by a centerless lapping process utilizing the same principle, but employing a much smaller abrasive grit size. Internal Cylindrical Grinder Cylindrical grinding processes apply to internal (Figure L-21) as well as external surfaces. Internal grinding uses …
Jun 01, 2016· The Doc Replies: Cam grinding is just a funky type of cylindrical grinding, where the shape isn't a basic circle but sort of an egg shape, which creates special challenges. In plunge-type cylindrical grinding, the basic equation for specific mrr (smrr) is: smrr (mm2/sec.) = DOC (mm) × workpiece surface velocity (mm/sec.).

Fives offers accurate, reliable, flexible, productive solutions for a variety of cylindrical-type parts grinding applications. The inherent design of the Fives' grinding machines is proven daily serving businesses successfully competing in today's global market.
Jan 01, 2014· In the automotive industry, CNC cam grinders have largely replaced rocker-type machines. On most CNC cam grinders, the wheel moves horizontally with the infeed velocity v fa, which is synchronized with the workpiece rotational speed n w to achieve the required cam-lobe form (tool path), as illustrated in Fig. 1(b). In both rocker- and CNC-grinding …
Grinding cams (the way I choose to do it) is a 4 step process that includes one rough grind and one finish grind, heat treating, and then a very gentle coolant supplied finish grind, to guarantee the cams are perfectly perpendicular after the heating process, and also to shine up the lobes.
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). CBN or diamond are used as an abrasive – for high cutting performance with a constant level of quality and a long tool life.
Grinding is most commonly used when a material is too hard to machine efficiently or when the tolerances required are too precise for machining. Rable Machine's grinding capabilities including centerless grinding, through feed grinding, plunge form grinding, O.D. Grinding, I.D. grinding & honing and surface grinding.
