Apr 01, 2018 Comp Cams has made numerous improvements to its CNC camshaft grinding process. The company has also implemented what it calls its “Micro Surface Enhancement” finishing technology, which works in tandem with its enhanced grinding process to
Cam relief grinding, however, overcomes the shortcomings of conventional cutter techniques, particularly in cutting tools with complex form geometry. The technique of Cam Relief grinding removes less material from the tool in the grinding process. This not only enables the cutting tools to be re-sharpened numerous times as compared to ...
Oct 29, 2004 Process optimization is an essential exercise for today’s evolving and adapting machine shop. Increasing international competition, short part runs and need-it-yesterday delivery requirements demand it. Unfortunately, optimizing a camshaft lobe grinding process has never been cut and dry.
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 contour.

The technique of Cam Relief grinding removes less material from the tool in the grinding process. This not only enables the cutting tools to be re-sharpened numerous times as compared to ...
In the process mentioned at the outset and used for cam contour grinding, an attempt was made to fix certain individual aspects of cam contour grinding using mathematical models and to derive therefrom process parameters, however the main focus of these efforts was trueness to shape, i.e. dimensional accuracy of the ground cams, while economic ...
In this process casted or forged CAM are in the required shape but their size is maintained by machining and finishing operation. B. While Using Metal Billet (metal rod), the profile of cam is obtained ... GRINDING JOURNALS: Here grinding and finish grinding of the 6 journals takes place. Carborundum wheels are used for grinding.
The Grinding Process Grinding is a material removal and surface generation process used to shape and finish components made of metals and other materials. The precision and surface ... cams from difficult-to-machine conductive and nonconductive materials. arbor The spindle of a grinding
May 01, 2009 The cam grinding process involves one pass across each of the lobes in high gear, with the wheel winding in at a preset speed to the desired base circle size, then a preset time delay with the wheel remaining in its final position against the lobe to allow the wheel to 'spark out'. After all lobes are rough ground the machine switches to low ...

Jun 22, 2007 Delta Cams will grind a cam for between $50 and $100 to any specification you give them and polish it, lubricate it for corrosion resistance and ship it back to you within a few days. These guys have spent years getting this process and equipment dialed in . . . I prefer to spend my extra time doing stuff that I can do better than anybody else. . .
Dec 23, 2018 Grinding Process: Mechanism of Grinding: In the grinding process, a layer of abrasive is responsible for removing the material from the work piece. As machining starts, the abrasives of grinding wheel and work piece comes into contact and due to the rubbing force the initial layer from the grinding wheel is worn out and a fresh layer of the ...
Commercial Cam Grinding Machines are adaptations of cylinderical grinding machines. The shafts they form are usually induction hardened before grinding, so distortion ooccurs and cylinderical grinding of the journals is required to being them into line. ... Grinding is a slow process and wheel wear, "loading-up" and the consequent need for ...
Manufacturing a steel roller cam for a Holden V8 engine. Many grinds or shapes are available in both hydraulic roller and solid roller applications. The hydr...
Apr 14, 2016 In this book, our aim is to achieve low cost, high quality and intelligent manufacturing for cam grinding. Part 1 is to study a novel grinding strategy for keeping the grinding depth constant during the cam grinding process. The GA-BP network in process parameters optimization in NC camshaft grinding is modeled and experimentally tested.

Jun 29, 2012 Grinding Process. COMP Cam’s Valvetrain Engineering Group has done an amazing job of streamlining the cam grinding process in the last few years. After a
GRINDING PROCESS with chamfer With radius CAM GRINDING 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 grinding, the grinding wheel follows the cam contour through interpolation of the workpiece spindle (C-axis) with the grinding spindle (X-axis).
A method of successively grinding a plurality of cams on a camshaft by performing a grinding cycle for each of the cams after each cam is brought into alignment with a grinding wheel through indexing movement in the axial direction thereof. The grinding cycle is performed with said camshaft being rotated and rocked respectively about its axis and a pivot axis parallel thereto and includes ...

Then, cam grinding process with CNC camshaft grinder is analyzed theoretically, and horizontal travel speed setting of wheel head correspond to the rotation speed of a workpiece is made clear in this study. Furthermore, simulation analysis method is developed, and proposed unique 3 grinding techniques to control the rotation speed of a ...
Here, the first centreless grinding process in the UK was introduced to combine rough and finish grinding of camshaft journals. It was in 1988 when the Rover Group was developing its highly acclaimed K- series engine that Derek Willis, then process engineer for this project, investigated the possibilities of centreless grinding.
Jun 01, 2016 Last year, I was involved in a fascinating project to optimize cam grinding for a major European truck manufacturer. Instead of using the constant-rpm or constant-mrr process, we developed the constant-temperature process, a complex, dynamic model of the ever-changing contact between the wheel and workpiece.
