The invention relates to a process for grinding of cams of a camshaft by means of a numerically-controlled camshaft grinding machine, whereby the camshaft is arranged in a workpiece mounting rotatably at preset angular velocity in predetermined angle steps about its longitudinal axis, and whereby a grinding wheel slide with a grinding wheel is infeedable in …


In the process, each angle is assigned a lift value to define the cam contour and import it to the program. The software then interpolates the values automatically. The cam contour is frequently concave in the infeed and discharge area. Here the concave radius determines the maximum grinding wheel diameter that can be used.


Oct 11, 2020· The kinetic finishing process does this by removing tiny peaks of material left behind after grinding while also minimizing the amount of side-to-side waviness across the surface of a camshaft lobe, thus increasing the effective surface-bearing area between a lobe and its mating lifter's roller.

Download Citation | Compensation technology of grinding deformation for engine camshaft | To solve the camshaft's deformation compressed by the …


The method permits the cam blank to be hardened before grinding to shape; Depending on the design of the machine, precise phasing of the cam lobes on a one-piece shaft is simplified compared to other methods. Several designs for …


Jan 01, 2005· When a crank or cam is polished on one of these machines, it uses about one inch of tape per journal, so fresh abrasive is used for every polishing job, but because it's such a small amount, many users say they've saved money. "One PER reported a 50-75 percent savings in the cost of tape vs. belts," Barton says.


Our camshaft grinders have the ability to perfect the proper lift, profile and duration of the reman camshaft. During the cam grinding process the cam follower is made virtually "like new". 13 Step Process for Remanufactured Camshafts: 1. Clean 2. Initial Inspection 3. Straightening 4. Recenter 5. Re-Threading 6.


Jul 03, 2021· Grinding wheels load up with material and need to be brought to square after each grounded lobe. Doing so posed time consuming process and not cost effective at all. Also the grinding wheel process wasnt smooth and required strong stabilization so that the wheel or cam doesnt bounce away when being ground.


Left: Large CNC Camshaft Grinder for camshafts up to 100" in length. Right: Hillcrest Camshaft Production Grinding for the Over-the-Road Truck Engines. Remanufactured Camshafts Offer Many Advantages: Purchasing a remanufactured camshaft is considerably less expensive than buying a brand new camshaft, but will deliver the same results.


Then, cam grinding process with CNC camshaft grinder is analyzed theoretically, and horizontal travel speed setting of wheel head correspond to the rotation speed of a workpiece is made clear in this study. Furthermore, simulation analysis method is developed, and proposed unique 3 grinding techniques to control the rotation speed of a ...


Jun 07, 2016· 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.


May 19, 2003· In 1998, Landis Gardner (Waynesboro, PA) launched a major effort to develop an alternative method that would overcome the size, complexity and cost disadvantages of the plunge grinding process. Chief among the alternatives evaluated was using the side of the grinding wheel to finish grind the cam and crank thrust faces.


Heat-treating a camshaft ensures the lobes will hold up under the demands of the valve train. Pushrods can apply as much as 2,000- to 6,000-lb loads between the lobe and roller wheels in a roller camshaft system, and as much as 10,000-lbs in Pro Stock engines. Most roller cams are made from either SAE 8620, SAE 5160, SAE 5150 steel or some ...
