Camshaft Grinding Use

At CAMS, we have the technology to grind camshafts with inclined cam lobes thanks to our CNC grinding machine that can set movement of the complete grinding wheel assembly at the same angle as the lifter movement. This is required for engines with valves pointing towards the center of the combustion chamber. A top notch example is the ...

More commonly you find that cam companies grind their street cams 4 degrees advanced to help boost low-speed torque on longer-duration cams. You can see this in the Comp XE274 example where the intake centerline is 106 degrees, but the LSA is 110 or 4 degrees advanced. Note that 110 degrees is exactly halfway between 106 and 114 degrees.

Oftentimes, grinding lobes and bearing journals is the final machining operation that completes an engine's camshaft. This is still the case for a number of offerings from Comp Cams, a leading manufacturer of aftermarket camshafts and valvetrain components for race, show and street vehicles.. The Memphis, Tennessee-based company has continued to adopt new grinding …

Important Tips to Remember When Degreeing a Camshaft. 1. You must always use the same type and size lifter that your camshaft was designed for. For example, you cannot use a .842" diameter lifter on a camshaft designed for a .875" diameter lifter. You cannot use a …

Cam Grinder Version: The Cam Grinder version is new for v4.3, and adds several features beyond what the Plus version does. It's features are specially designed for customers who typically grind cams or need to send files to cam grinders for special custom grinds. The Cam Grinder version also gets into more detailed analysis than the typical ...

Once that relationship is established by grinding the cam, the lobe separation angle cannot be changed unless a new camshaft is machined. This makes engine development and tuning somewhat difficult with any cam-in-block pushrod engine because changing the lobe separation angle requires a new camshaft. If we were working on a dual overhead cam ...

The computer numerical control (CNC) camshaft grinders and cubic boron nitride (CBN) wheels have advanced dramatically in recent years and exerted great influence on the progress of high-speed grinding of camshaft. However the high-speed grinding is often accompanied by complicated vibration behaviors[2].

THERE IS ONE CAM GRINDER (HAS A SMOKIN' WOOD PECKER FOR A LOGO) I CALLED THIS DUDE CUZ I ALREADY HAD HIS RV-1 CAMSHAFT W/ 260 DEGREES DURATION–JUST WANTED INFO RE; DEGREES DURATION @ 0.050" lift. can you believe this tight ass peckerhead wanted $35.oo to 'answer any questions.'

Crower Camshafts. Crower has been designing and grinding hot-street and cutting-edge full race profiles for over 50 years. Camshafts are the most critical part of your engine's performance. Camshafts use a combination of separation angles, lift, duration and lobe acceleration/ramp rates to create what is called a cam profile.

All of these technologies are available for use on flat tappet cams—and in some cases, lifters—but some of these processes and are cost-prohibitive for many of us individuals. New Lifter Tech Bred Cam Profile Changes With this new lifter technology, cam profiles changed. Camshaft grinders note that the gains have been incremental.

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: If the master …

The cam grinder or engine builder cannot know about driving styles and rpm ranges in your application without good accurate information on which to base his recommendations. There are two easy ways to change the characteristics of your cam. Advancing and retarding the cam can move the power band up or down a few hundred rpm.

We provide camshaft grinding services as well as supplying new and reconditioned cams, including performance camshafts. As a manufacturer and distributor, we can meet your camshaft needs. Whether you need a performance camshaft, racing camshaft, competition camshaft or a cam for a Chevy, Ford, Honda or other make of car or truck, we can help.

Furthermore, simulation analysis method is developed, and proposed unique 3 grinding techniques to control the rotation speed of a workpiece are investigated. In the methods, it is certified that fluctuations of the grinding results are reduced, and the precision cam grinding method is realized. KW - CNC Camshaft Grinder. KW - Cam Grinding.

Centreless grinding of crankshaft bearing journals is in many respects similar to camshaft grinding. The main differences are: Camshafts are rough ground directly from the cast condition, while crankshafts may have to be pre-turned. The diameter tolerances for crankshafts are often even tighter than those for camshafts.

With more than 45 years of camshaft grinding experience, you can trust us to know what to do to each type of camshaft to extract the ultimate performance and reliability. We have performance profiles for a range of Japanese, English, American and European engines, such as: Honda - VTEC 1600-2200cc

Video: Turbo Cams 101—The Science of Turbo-Specific Camshaft Designs. Picking camshaft specs has never been an easy task for the layperson. Camshaft companies have done their best to make camshafts as easy to understand as possible, and by and large, the average enthusiast does have a far more solid grasp on camshaft selection than in years ...

Don't trust any company with your diesel engine camshafts, call the experts at Hillcrest Camshaft. With over 150 years of combined camshaft experience, we use some of the most state of the art testing and grinding equipment today.

Grinding and polishing damaged cam journals can save the rebuilder about $150 by not having to purchase a new roller camshaft." The relationship between the cam and lifter – in a flat tappet cam – is critical, explains Popp. "The taper and the crown of the camshaft lobe isn't flat across.

Larger cam lobes permit the use of lift, duration, and profile combinations not possible on stock cams. Larger lobe sizes allow the camshaft designer to utilize standard base circles and clearance ramps while attaining profiles that produce high lift. All Eagle Camshafts are ground on new billets.

Oregon Cam Grinding was founded in Oregon in 1984 by the Heard family. The company specializes in grinding and remanufacturing camshafts for automotive and industrial uses. Because of the Heard family's commitment to racing and the performance car hobby, the company also distributes camshafts, cranks, pistons and related engine parts for racing and high performance engines.

Cam Rule #2: The most common mistake in a cam selection is to select a cam that is too big, thus hurting performance. If you are deciding between two camshafts, typically the smaller grind is the wise choice. If your knowledge is limited and you are set on selecting a cam yourself, pay the closest attention to two elements that are advertised ...

Cam-grinding geometry. The Jaeger Model . In the 1970s, to avoid grinding burn, grinding engineers started applying the 1942 Jaeger moving-heat-source model to predict workpiece temperatures. Most used the specific energy, which is the energy required to remove one cubic millimeter of material. Specific energy depends on the average chip ...

As a manufacturer, we perform custom camshaft grinding to factory or performance profiles. We can, when it's cost-effective, perform additional camshaft repairs such as lobe welding, repair of bearings, thrust areas, dowel pins and keyways. We use our cam expertise to solve your camshaft problem in a manner that's most cost-effective for you.

Limitations: Increased cost, limited rpm range. Frequently used in today's OEM factory engines and mild to moderately aggressive performance engines, hydraulic roller cams use lifters equipped with a roller wheel that tracks along the camshaft lobe, reducing wear and friction, and enabling faster lobe ramp rates than flat tappet cams.
