Find local businesses, view maps and get driving directions in Google Maps. Stock or small cfm carburetor, small diameter tube headers and dual exhaust are recommended for maximum benefit. Hermitage, PA 16148. Distance between centers: 0 mm - 4,100 mm. A polishing belt is then used on the bearing areas to remove any discoloration that may have occurred during manufacturing. Short TrackThe Short Track series was originally designed for 1/4, 3/8 & 1/2 mile tracks, however these profiles can be used in a broad range of applications including Hot Street. It is highly recommended whenever you rebuild your engine that you replace or regrind your camshaft. Headers, dual exhaust, large cfm carburetor, performance ignition and increased compression of 10.25:1 and above are required. Cam grinding wheels are available for both steel and cast. This is because of the cam's geometry. First, when the workpiece slows down, the chip thickness decreases. The issue with converting a 50-year-old machine to be somewhat CNC is you're still very limited by what type of profile you can grind and your wheel size. 390 Ball Nose HydraulicThe 390 Ball Nose Hydraulic series utilizes short seat duration and fast lift rates to increase the area under the lift curve and create a broad operating power range. However, we can accept e-mail orders as well. A forum community dedicated to hot rod owners and enthusiasts. These bearing sizes are also available in 4-7 & 4-7-3-2 (LS1) firing order configurations. Because of waters ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. In its finishing role, the grinder is perhaps the most widely used machine tool. Thanks, Oregon Cam Grinding, for the fast turnaround on the locomotive camshaft regrinding job. The process also exposes unused, sharp abrasive points. Please fill out theCrower Camshaft formand submit it to us. The camshaft is now ready to be shipped or picked up. 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 profiles are tracked onto the cams, and any custom lobe separations can now be made manually using the headstock. Custom camshafts are available to suit your unique application, please call our tech department if you cannot find what you are looking for. ); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

Grinding burn, or thermal damage, occurs when the workpiece material properties are changed, usually detrimentally, because of high grinding temperatures. Previously, the only ways to evaluate grinding burn were: 1) to cut, polish and etch the workpiece and examine its microstructure under a microscope, looking for white layer; 2) to remove a small section and send it for X-ray-diffraction measurement; or 3) to dip the entire part in nitric acid and look for white layer. See loading; truing. This is still the case for a number of offerings from Comp Cams, a leading manufacturer of aftermarket camshafts and valvetrain components for race, show and street vehicles..

This is an ideal series for engine builders looking for the ultimate in flat tappet camshaft design. And all of them use a trial-and-error process: They choose a set of speeds and feeds, somewhat arbitrarily, and grind a camshaft. This series is avalilable in all the oversized cam bearing configurations and firing orders. If private label custom camshaft grinding is desired we offer that service as well. We have over 500 cam profiles on hard masters and can produce new cam profiles from scratch. Just be truthful with your specifications and you will have a correct cam for your application. Here, the grinding wheel spindle power was measured and, if the power exceeded some predetermined level, the workpiece rpm again slowed down. The workpiece is usually cylindrical, but it may be tapered or curvilinear in profile. To complicate matters, grinding machines have limitations on how fast the wheel-spindle assembly can oscillate back and forth, how quickly it can change direction and how quickly the workpiece can accelerate and decelerate. True CNC cam grinders will provide you with many additional options in grinding that you will not have with older machinery. We keep 1,500+ camshaft cores in stock at all times to accommodate a wide variety of grinds and material. Figure 4. This series also uses a ball nose design to help improve durability.

As a manufacturer and distributor, we can meet your camshaft needs. steel cranks, Eagle rods, aluminum cylinder heads, roller cams, lifters, Different camshafts have different firing orders. See superabrasive tools. Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. In this case, there were two jerks: the jerk in the wheel-spindle-assembly acceleration (how quickly the machine could change the linear acceleration of the wheel oscillation) and the jerk in the workpiece angular acceleration (how fast the machine could change the rotational acceleration of the workpiece).
