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 ...
Virtual camshaft part is a very important information carrier for camshaft virtual high-speed grinding. The veracity and maturity of process correlation information, which holding on the virtual ...
The engine's timing belt drives the camshaft (s) ("top end") from the rotation of the crankshaft ("bottom end"). The belt keeps the piston and valves in "time" during operation. Serious internal engine damage can occur when the piston and valves come into contact with each other "out-of-time" caused by a damaged belt etc.

When diagnosing a shudder vibration condition on some 2016-2018 Silverado, Sierra; 2016-2020 Tahoe, Suburban, Yukon; 2019-2020 Silverado 1500 and Sierra 1500 models equipped with 5.3L V8 engine (RPO L82, L83, L84) and 6L80 6-speed transmission (RPO MYC), it's critical to determine the source of the vibration in order to make the proper repairs.
Cam grinding the CNC way. If you talk to anyone in the camshaft manufacturing business, it isn't very long before the name of Landis crops up. Old timers might reflect fondly on such machines as the Berco RAC1500 cam grinder - "The best manual cam grinder in the business" or be rather less complementary about the Storm Vulcan machine going back into the 1950s, but the one …
Here is my latest escapade. For the last 5ish years. Ive been tinkering around building a camshaft grinder, mostly centered around grinding modular ford cams, but does accept any cam with nearly 30" length. My first go at grinding i had it set up similar like an actual cam grinder. Using a...
Valve lifters play a key role in the valvetrain of pushrod engines. They go all the way back to the earliest days of the internal combustion engine. The earliest engines did not have pushrods or rocker arms. They were a "flathead" design with the valves in the block. The lifters (also called "tappets" because of the clattering noise they produced) rode on the cam lobes in the block and ...
Certain late model BMWs can experience a problem with the camshaft sprocket retention bolts failing. This is a design defect, and well know in professional BMW service circles. You can see on the photo below, that VANOS (variable valve timing system) to intake camshaft bolts have broken and backed out, 3 of the 4 bolts are damaged and loose.
The trick is getting the profile to fit the core—this picture shows the case-hardened rim around the raw cam lobe. To ensure the depth of the hard surface remains 0.100in or more, careful indexing of the lobe profile is vital during the grinding process
Camshaft Machine Company (CMC) located in Jackson, Michigan was established in 1942 and is probably the largest designer and manufacturer of automotive camshafts in the world. CMC produces cams for GM, Ford, Chrysler, Comp Cams, Lunati, Edlebrock, Crane, Wolverine and many others. Most (but not all) of the automotive camshafts produced today ...

So today was my first suare at grinding 304ss. My what an experience. I had my best results with 2-3 tenth downfeed and 40-60 thou cross feed. Forgive me I can't remember the wheel grit, I think it was 38. I used a piece of "lip balm" wax as my coolant but man it it thermally sensitive. It was a piece of prodec 304ss 5x7 I brought it down to .756.

I have been hearing a grinding noise in the engine on start-up after parking overnight and recently after only sitting parked for 2 to 2 and 1/2 hours. I heard it only once in a while initially (once a week or so) and for only a second or two. Now, it's everyday, more than once a day, lasts a...

birdman1 said: ↑. I sent the cam out of my 430 Lincoln engine to Oregon cam grinding. It had two very worn lobes they built up the worn lobes and reground it to 1969 428 Cobra jet specs (hydraulic). I broke it in with Lucas breaking oil. It is an excellent grind for the street, has a great sound and it made the 430 into a very responsive engine.
Abstract: Based on NC system of Siemens 840D, and taking Permanent Magnet Synchronous Motor (PMSM) as control object, each sector of rotational axis (Axis C) and wheel feed shaft (Axis X) which affect the camshaft grinding accuracy, is thoroughly analyzed in this paper by mechanism analysis. In accordance to the method of Three Loop Control (Current Loop-Speed Loop …
VANOS stands for Variable Camshaft Timing, which is a valve timing system used, in conjunction with Valvetronic, on the BMW N55 engine. To keep it short, BMW VANOS (or Double VANOS on the N55) adjusts the timing of the intake and exhaust camshafts based …

Grinding. There are many different car systems that can make a grinding noise, but when just focused on the engine alone, it could be due to worn-out bearings. If this is the case, you will hear the grinding sound when driving or idling.
A novel non-circular grinding technique which utilizes two grinding wheels of different diameters is proposed for the locomotive camshaft with concave curves. The larger grinding wheel is used for rough machining to increase grinding efficiency and the smaller is used for finish machining to form the cam profile accurately. Based on the analysis of motion law of grinding carriage and headstock ...
