Converting Profile to Cam Grinding Wheel Path (using mm lift, using inches is very similar) We will describe converting a profile measured with a smaller diameter roller to a larger diameter Cam Grinding …
The cam & master cam rotates at 20 RPM, the grinding wheel @ 7500 RPM. The Stylus was changed was using a 1/2" travel micrometer barrel for adjustment instead of the 3/8"-24 TPI adjuster & added a roller bearing tip to follow the master cam.
Cam and Camshaft Grinders Kopp of the EMAG Group offers machines tailored to the grinding of cams and camshafts. Multiple operations, including internal and external machining as well as grinding for single-part and batch production.
Radical cam lobe profiles can really push the limits of cam grinding equipment. Fortunately, our new Okuma machines address several of these issues. For instance, the negative radius of curvature ...

Of all the various ways to form harmonic cams for model four-stroke engines, the method with the greatest potential for accuracy and repeatability is to use a machine that grinds the cam from a scaled up master cam profile. The advantages include:
how well the grinding process is executed, a camshaft is only as good as the design and engineering being applied.Camshaft lobe profiles control the critical open-
Turn broaching—A machining operation for roughing lobe profiles that uses a large-diameter cutting wheel with many inserts around its perimeter to rough-cut lobe profiles before finish grinding. Green grinding —A process of grinding a lobe profile from round barstock.
Cam profiles for (flat) bucket tappets are convex and relatively easy to grind with a free choice of grinding wheel diameter as the radius of curvature of the profile is always positive.

Colt Cams Inc. We house the largest selection of camshaft master profiles in Canada, consisting of well over 2200 profiles which we are constantly adding to.
COMP Cams leads the industry in camshaft lobe offerings. With over 3000 active lobes in its library the combinations are infinite for a given engine.
I installed the grind #648, supposedly similar specs to the Ford OTC SCJ cam, and the numbers on the cam card are close, but not the same as what was on that list.
The first step is to set up the cam grinding machine for the application that will be performed. This is accomplished by loading the desired profile onto the tracking headstock.
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.
Oregon Cam Grinding is located in Vancouver, Washington, near Portland, Oregon in the scenic Pacific Northwest. We provide camshaft grinding services as well as supplying new and reconditioned cams, including performance camshafts.
2007-06-22· Modern camshafts are "assembled" from powdered metal cam profiles, fixtured on a steel tube, and then a ball is drawn thru the ID of the tube, expanding the metal and locking all the profiles in their respective orientations. The best materials can be then used for the oil pump gear, the bearing journals, and the cam profiles. A single cast stick, ground, and hardened is somewhat of a tradeoff ...

Understanding Cam Profile Terms. RAMPS The parts of a camshaft lobe that actually initiate the lifting and descending movement of the lifter are called "ramps".
Traditionally the production grinding of camshaft profiles has been mechanically copying from a master campack. This has the disadvantage of cost and lead time to manufacture the master cam and places restrictions on accuracy and production rate.
Oregon Cam Grinding has masters for all the cams grinds shown and can grind most any of them on your core for $70. They also have a pretty good core bank and last time I …
