VolPort, the leading enterprise of Chinese crushing and grinding industries, has always been dedicated to the development of ore crushers, sand-making machines and industrial grinders in the past 30 years.
In surface grinding it is necessary to reverse one of the more usual principles of machining used in most of the other chip-making processes. In both turning and milling for metal-cutting volume, the machinist tries to keep the depth of cut to a maximum, adjusting all the other variables such as speed and feeds to match that concept.

CamShaft Regrinding Camshafts control the opening, closing, lift and duration of valves. This means precision is essential to engine power, pick-up and fuel economy. Wear on your camshaft will cause excessive valve noises, engine roughness when idling, a …
The cam is connected by a 2-1 ratio sprocket or gears, so it only turns once to the crank's two turns (Two crank degrees equal one cam degree). When viewed from the front of the car, the crankshaft turns clockwise. The camshaft also turns …
The cam profile and the cam tappet interface are normally produced by grinding the surfaces. Typically, a simple grinding operation will produce the surface finish that is measured at 0.25 micron as a centre-line-average (CLA). This is the average height of the asperities on the surface. If the surface is first

Cam grinding is a form of cylindrical grinding. Most cam grinding machines are custom fitted to the part being ground. In generating camshapes, some variation in grain and grade can improve results. Cam grinding wheels are available for both steel and cast. Your Partner for the Machining of Crankshafts and Camshafts.
The grind number gives you the basic cam info. Like the Crane 274HO6-tells you the adv. duration is 274 degrees, H is for hydraulic, an 06 tells you the lobe separation angle of 106. Part number is 100172 which really tells you nothing. The cam companies all have their own "grind numbers". Some actually give you some cam data, others do not ...

A cam is a bump on a circle. When the lifter is riding on the circle, it's at zero lift. as the cam rotates, the lifter sides over the bump. Regrinding a cam is making the circle smaller, in order to make the bump bigger so it can be reshaped. David four-thirteen, Dec 1, 2004 SHARE POST #4 Hemi Joel and silent rick like this.

Engine Size and Compression: A cam’s profile is affected by displacement. Most cam descriptions for small block Chevys, for example, are based on 350 cubic inch engines. Put a cam in a 383 stroker and it will act like a milder grind. The more duration a cam has, the more compression is needed to maintain proper cylinder pressure at low rpm.

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 where's the problem?
Commercial Cam Grinding Machines are adaptations of cylinderical grinding machines. The shafts they form are usually induction hardened before grinding, so distortion ooccurs and cylinderical grinding of the journals is required to …
BTW, the leading CAD software for Pros is SolidWorks, and the leading CAM software is Mastercam, though Fusion 360 is moving up fast. Pros need the software that performs best for someone who is an expert in using the software. They want CAD that lets experts create precision drawings faster.

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 …

A Basic Overview of Cam Timing. To advance or retard a camshaft is to change the alignment between the camshaft and the crankshaft. When a cam is installed "straight-up," the imaginary centerlines of the two shafts line up exactly. Advancing or retarding the cam pushes the centerline of the camshaft to one side or the other of the crankshaft ...
This gentle scrubbing action removes rust, grease, and baked-on oil. The next step in the camshaft grinding process is where the camshaft is verified for straightness and the centers are verified for true. The centers are used to drive the camshaft, along with the dowel pin or keyway. The main bearing area is straightened within one-thousandths ...

The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.
On this shaft are cams or lobes - the egg-shaped bulges which, because their rotation is concentric to the shaft, can perform the function of moving a mechanism called the cam …
