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 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.

GRINDING ON FACE: An angular grinding wheel is used for the face grinding operation. At this stage, inspection is done after every 10 components using gauges. 6. DRILL DOVEL HOLE: Grinding of the Cam is done here. The dowel hole is taken as the reference. 7. LAPPING: To give superfinish in microns, lapping is done using
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.
Advantages of centreless grinding. The benefits of centreless grinding when compared with multi-wheel processes include: Less stock removal. A centreless machine works 'on the diameter' while a multi-wheel grinder works 'on the radius.' All concentric diameters can normally be ground simultaneously using a centreless machine. Less run-out.
Engine Cam Grinding. I was looking for thoughts on a concept of a cnc cam grinder. The purpose would be for small engines but the concept would be universal to cam grinding. I would like to make a two axis machine. One axis would be a rotary the other would be Y (I think) that would move in and out on a plane parallel to the base of the grinder.
Grinding wheel changer A real machine enhancement from WALTER. With a capacity of 6, 12 or 24 stations and a maximum of 72 grinding wheels it multiplies the grinding performance of the HELITRONIC VISION 700 L. The wheel set and coolant supply are arranged on the changer as a compact unit. Minimal changing
A member of the UNITED GRINDING Group CamGrind S Small and versatile Key data The CamGrind S allows you to grind shaft-type workpieces with a length of up to 650 mm. This small, versatile grinding machine guarantees high-precision grinding results in cylindrical and noncircular grinding.
The invention claimed is: 1. A method for grinding of cam profiles on a camshaft (1), which camshaft (1) has an inner shaft (5) and an outer shaft (4) arranged coaxially one inside the other and mounted with respect to one another, has first cams (2) and second cams (3) that can rotate with respect to one another about the camshaft axis (6) over a limited circumferential angle, …
Helical parts most commonly cut on the milling machine include helical gears, spiral flute milling cutters, twist drills, and helical cam grooves. When milling a helix, a universal index head is used to rotate the workpiece at the proper rate of speed while the piece is fed against the cutter.

Our purpose is to provide information about vintage machinery that is generally difficult to locate. VintageMachinery.org does not provide support or parts for any machines on this site nor do …
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 cutting surface of a new wheel will run out slightly due to the clearance between the wheel bore and machine spindle (Figure L-51). Truing a wheel will bring every point on its cutting surface concentric with the machine spindle. This concentricity is important for achieving smooth and accurate grinding conditions.
In FIGS. 1 and 2, a cam grinding machine for grinding the cams of a camshaft 2 is designated generally by reference numeral 1. The camshaft 2 can be rotated about its longitudinal axis, the so-called C axis. To this end, the camshaft 2 is mounted on its one end in a driver 5 of a work headstock, while its other end is seated in a footstock 6.
Grinding from solid eliminates the need for a cutting machine and all the complementary tooling and equipment required to start and maintain the rough cutting operation Typically a rough-ground gear will be of higher quality than a hobbed, near-net, or cut hear – particularly larger spur gears and gear sets
The Sherline cam grinder was designed with the home shop machinist in mind. We have assumed that the user has some knowledge of g-code, CNC, and how to square up or "tram in" a machine, so all axes are properly aligned. The machine is carefully pre-aligned at the factory, but rough handling in shipping could knock something out of alignment.

Spring technology for flat tappet camshafts has improved. The beehive-style spring is a good example. Here, the oval/multi-arc wire shape places the maximum area of the wire at the point of highest stress to handle valvetrain stress more efficiently, and gets better heat dissipation for longer life.
The cam is a regrind done by a shop in Somerset, Ky: Reed Coronet's Auto Machine Shop. It's possible to get some pretty radical lifts on flathead cams. One method would be to overbore the cam tunnel for a larger bearing from a different engine, sleeve the camshaft journal with a press fit bushing, Then build up the lobes with a sintered alloy ...
