Nodular cast iron QT700-2 is extensively used in automobile engine crankshaft parts due to its prime mechanical properties. The journal of a crankshaft is a curved surface, and traditional wheel grinding easily causes grinding burn and surface and subsurface damage. Shape adaptive grinding (SAG) is a flexible grinding technology, …

No doubt much of his knowledge stems from a life in the competitive arena of race engine building. Raw, un-ground camshafts have a case-hardened rim on each lobe that penetrates this working surface by 0.200in to 0.250in. When finish-ground, the case-hardened surfaces must achieve a minimum depth of 0.100in. If less, the lobe will be …
The GC-34NH CNC Cam Grinder can grind a variety of "non-round" shapes on the OD of a part, such as ovals, flats, triangles, and even squares. A Common Non-Round Challenge: Changeover Time For all of you motorheads and race fans, let's take a look at the example of an aftermarket camshaft.
Features include: Powerful 1/2 HP grinder motor (120 VAC) 3 DC stepper motors with manual control handwheels Flexible way covers on Y-axis keeps water and grinding debris off Y-axis leadscrew Holds cam blanks …
Cam grinders can create lobe shapes that give long durations, allowing engines to rev well into the 8-10,000 rpm range because they can "breath." Those same engines, however, exhibit very poor running characteristics …
But it would seem to me that someone who does cam grinding could regrind your stock cam, if you still have it. If it's not pitted, they could just take a few thou. off. You could make up the difference in the adjustment. It's light and small enough that they wouldn't have to be close to you. It could be shipped anywhere.

If you have a 4.500-inch stroke and a 6.500-inch rod (center-to-center) you have a rod ratio of 1.44:1. For a boosted application, you want as much piston dwell time as possible at each end of the ...
I've inquired if either cam will accept grind number 722, which is 222/[email protected], 277/[email protected], and .309/.320 lobe lift. It comes on a 112 LSA, but Ken says you're limited by plus or minus one or two degree degrees of what the factory LSA is. Stock LA truck cams are 106 to 111 LSA and the car cams are 114 to 116.
Cam Relief grinding is a technique for grinding a form on the cutting edges of cutting tools. This technique utilizes a cam relief fixture to advance the cutting tool toward the grinding wheel at a constant rate, while it is …

Many cams have only .080" or less of heat-treat. Cams can generally be ground +/-3* in LSA, and +/- .025" in lobe lift. These are the more important numbers. So this means you cannot regrind a .370" lobe lift, 106 LSA cam into a .450" lobe lift, 112 LSA cam. The grinding process with go through the heat-treat on both the nose, and on the …
As we all know, the purpose of a camshaft is to open and close a valve at a certain time; the camshaft is defined by valve lift, and duration which is further defined as opening and closing points. But through those three points (open, lift, close) an infinite number of curves can be drawn. Each curve (lobe shape) will determine how the valve ...
That depth of hardness allows the finish cam grinder to finish grind the cam lobes with a Rockwell hardness above 50Rc. The generally accepted hardness on a finished cast cam should be between 48Rc to 58Rc. All of the finished cams that we have checked are always above 50Rc hardness on the lobes.

Raw, un-ground camshafts have a case-hardened rim on each lobe that penetrates this working surface by 0.200in to 0.250in. When finish-ground, the case-hardened surfaces must achieve a minimum depth of 0.100in. If less, the lobe will be impaired and likely fail. But the camshaft grinder has around 0.150in to work with, so …
The EV27 is almost a replica of the old "L-grind" cam (1981-1991) of the early 90's, prior to the EPA foot crushing decent HPs.....with exception of the duration. Afterwards, the "N-Grind" cam was introduced, and is shaped like an egg, with no flat area denoting duration.

Performance cams typically have durations ranging from 220 up to 280 degrees or more. The longer the duration, the rougher the idle and the higher the cam's power range on the rpm scale. A cam with a duration of 240 degrees of higher will typically produce the most power from 3,500 to 7,000 rpm.
