There may be company specific information, like cam grind number or part number, but much of the information is similar from one manufacturer to another. When reading a cam spec card, the first thing that should be printed near the top is the type, style and application. A V8 Chevy 262-400ci, 1955-1998 engine should have a camshaft built ...

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 …

Comp Cams uses a variety of wheel brands depending on the camshaft being ground, and performs tests to measure the electrical current during a grinding operation when selecting grinding wheels for a given application.

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 …

It is true that many camshafts are designed with advance built into them. The majority of these cams are intended for street use. Here's how it all comes together. The cam companies know that when it comes to choosing a …

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 ...

This is my final assignment in the last year in my college. It's all about the simulation of the machine and how it work. This machine is manually operated, ...

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.

Way back in 1983, the Camcraft Cams business began as a division of R&R Automotive. Initially, we specialized in supplying medium and large engine rebuilders up and down the East Coast with reground automotive camshafts for their rebuilt engines. Today, we've grown into a leading automotive performance camshaft production manufacturer with customers scattered …

Camshaft "B", has intake and exhaust lobes that are both at 260 degrees. Camshaft "A" is referred to as a dual pattern, while camshaft "B" is referred to as a single pattern. With the advent of emissions laws and the widespread use of computer systems, more modern single and dual profile pattern designs have been developed.

Engle cams are the #1 requested camshaft for all air-cooled Volkswagen motors. In addition to Volkswagen, we produces a wide range of cams for American Motors, Buick, Chevrolet, Chrysler, Dodge, Ford, Mercury, Oldsmobile, and Plymouth. Unlike some of our competitors, we use cam blanks made in America from American iron!

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 ...

With the CamGrind S you can grind camshafts with a length of up to 650 mm. This small, versatile grinding machine guarantees high-precision grinding results in cylindrical and noncircular grinding. Swing: 11.81 in. Centers: 25.59 in.

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 ...

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.

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.

Step Five: Grinding the Camshaft Journals. A diamond grinding wheel gives each journal a precision surface. (Image/Summit Racing – Brian Nutter) This is a Landis Model 3LB Cylindrical CNC Grinder using a CBN diamond grinding wheel to precision-grind each camshaft journal. This process results in superior cam roundness, eccentricity, and runout.

Crow "NEXT GEN" LS camshaft profiles use a totally new CNC master generation system to produce cams with higher lift and larger 200" duration figures for significantly more power and mid range torque. Next Gen profiles high tightly controlled rates of acceleration so that spring and valve train bearing life is not compromised.

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.

tweaks the grinding machine (including CNC grinders) causing it to stretch or distort the actual grinding path of the master to achieve a "morphed" cam lobe and then builds a second master from the morphed lobe. This is not cam design by any stretch of the imagination, yet many cam grinders unfortunately still use

#lathe #camshaft camshaft grinder on lathe, very easy to use

Purchase a cam designed for use with roller-lifters. This is not a strict necessity; you could go with an old-school flat-tappet camshaft, but you are losing out on horsepower, torque and quite possibly fuel efficiency. A roller-tappet camshaft allows the valves to open and close quicker, which allows you to run a bit less lobe separation while ...
