Home Tech Articles. Camshaft Basics The terms associated with camshafts are also not always understood, or more often Misunderstood. Practically everyone understands what "Valve Lift is, but the terms 'Cam Centerline" and "Lobe Separation" and "Base Circle" are terms which will get different explanations from different people.


Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.

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 and camshaft grinding - the Basics. Camshaft Basics. Webster's Dictionary defines 'camshaft' as "a shaft bearing integral cams." Webster's defines a 'cam' as a disk or cylinder having an irregular form such that its rotary motion gives to a part or parts in contact with it a specific rocking or reciprocating motion. In an internal ...

A surface grinding machine is used to produce a smooth accurate finish on either metallic or nonmetallic materials. It uses a round rotating abrasive grinding wheel that remains stationary (but rotating) while the feed table (with work attached) is run in a reciprocating motion (left and right) under the grinding wheel.


Choosing the Correct Camshaft for the Build. Choosing a particular type of camshaft for an engine build is an important decision that has to be made before any other parts are ordered or machined. Choosing a cam requires answering some basic questions, the most important of which is the engine application itself. Advertisement. By. Engine Builder.


For this initial foray, let's use a simple, hydraulic flat-tappet camshaft from Erson (Card A). We're going to start with some basics on cam design so we don't lose anybody in the description. A cam lobe is designed around a few basic parameters …


This means the number of crankshaft degrees the cam holds the valve open from the point that it raises 0.050-inch off the seat until it is lowered to within 0.050 from the seat. Most cam cards will provide duration numbers at 0.050, and it is easy to measure at this amount of lift. Begin as you did before with a dial indicator on the lobe of ...


Camshaft Basics and Terminology. The Camshaft is the "heart" of the gasoline engine. ... Dual Pattern Cam - if the intake and exhaust lobes have a different grind, the cam is called a dual pattern cam or dual pattern grind. From the earliest days of cam design, it has been common to use an exhaust lobe with 10 to 20 degrees more duration than ...


unchanged. This paper serves as a basic overview of how a lens is manufactured from a blank. A lens is typically ordered from a glass company in a form called a glass blank. From there, the lens goes through generation where the rough shape is ground into the blank. A lens is then blocked and undergoes further grinding to improve the surface ...

Aluminum oxide grinding wheel is commonly used in making the grinding wheel and will be best suited for grinding the ferrous metals having high tensile strength e.g. hard steel, wrought iron etc. ; Silicon carbide grinding wheel is used to grind the softer, low tensile strength, high density and non-ferrous materials such as brass, aluminum and softer bronze.


Cam grinding is one of the more complex grinding operations. This is because of the cam's geometry. In standard, cylindrical grinding, such as for producing shafts and pistons, as the workpiece rotates and the wheel plunges in, the material-removal rate and wheel-workpiece contact area are both constant.


The Basics. The design process is different for every application, but the basics are the same – create a profile for the intake and exhaust lobes for the type of engine the cam is for. ... Once the rough grind is done, the cam moves to the …

Reading a Cam Card: Rocker Arm Ratio (Rocker Ratio) On that same line in this cam card, the lift at the valve has increased from 0.321-inch at the lobe, to 0.545-inch at the valve. This is accomplished through the rocker ratio. Note that the card calls this ratio out at 1.7:1. If we multiply 0.321 x 1.7 = 0.545-inch.

grinding should be considered. Starting with a broad surface of a soft steel like AISI 1018, a suitable selection of wheel and grinding variables would be as follows: an aluminum oxide abrasive of 46-grit size in a J-bond hardness. The bond itself is vitrified. The wheel speed for vitrified wheels is usually from 5500 to 6500 sfpm; the table ...
