Oftentimes, grinding lobes and bearing journals is the final machining operation that completes an engine's camshaft. 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.. The Memphis, Tennessee-based company has continued to adopt …
P0016 code definition. Camshaft Position A - Camshaft Position Correlation (Bank 1) What the P0016 code means. P0016 is the OBD-II generic code indicating that the camshaft position sensor for bank 1 does not correlate to the signal from the crankshaft position sensor.
16. Loosen the camshaft holder bolts, in sequence, two turns at a time. 17. Remove the five camshaft holders. Set them aside on a clean surface in the exact order and position that they were removed from the cylinder head. 18. Carefully tip up the end of the intake camshaft until there is enough slack for an assistant to lift the chain off the
Here is my latest escapade. For the last 5ish years. Ive been tinkering around building a camshaft grinder, mostly centered around grinding modular ford cams, but does accept any cam with nearly 30" length. My first go at grinding i had it set up similar like an actual cam grinder. Using a...
The chatter characteristic of camshaft grinding is basically consistent with the analysis results in section 4.2. Therefore, the mode center frequency and energy entropy based on improved VMD can not only effectively identify the chatter of camshaft grinding, but also can identify the chatter of different contour segments. 5.2.
Case Based Reasoning (CBR) is a novel paradigm that uses previous cases to solve new, unseen and different problems. However, redundant features may not only dramatically increase the case memory, but also make the case retrieval more time-consuming. Furthermore, camshaft grinding process is controlled by a number of process parameters, …
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 method serves for grinding two or more cams of a camshaft. Initially the camshaft is chucked in a mounting position between a driver of a work headstock seated to rotate about a …

Certain late model BMWs can experience a problem with the camshaft sprocket retention bolts failing. This is a design defect, and well know in professional BMW service circles. You can see on the photo below, that VANOS (variable valve timing system) to intake camshaft bolts have broken and backed out, 3 of the 4 bolts are damaged and loose.
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.
How to grind camshaft
I have been hearing a grinding noise in the engine on start-up after parking overnight and recently after only sitting parked for 2 to 2 and 1/2 hours. I heard it only once in a while initially (once a week or so) and for only a second or two. Now, it's everyday, more than once a day, lasts a...
hot-pressed grinding wheels for the steel industry for the grinding of slabs and billets. Furthermore, the product range consists of roll grinding and centerless grinding wheels for the steel industry and large diameter precision grinding wheels for cam and crankshaft grinding.

Conditions for changing acceleration and force spindle when the high-speed high-precision camshaft grinding with the action of follow grinding and the constant linear speed grinding,a step-pocket cavity hydrostatic -hydrodynamic bearings is designed to meet this precision camshaft grinding, and the relationship between eccentricity and bearing stiffness, load are …
Based on NC system of Siemens 840D, and taking Permanent Magnet Synchronous Motor (PMSM) as control object, each sector of rotational axis (Axis C) and wheel feed shaft (Axis X) which affect the camshaft grinding accuracy, is thoroughly analyzed in this paper by mechanism analysis. In accordance to the method of Three Loop Control (Current …
Virtual camshaft part is a very important information carrier for camshaft virtual high-speed grinding. The veracity and maturity of process correlation information, which holding on …
Over £1.4 million of recent investment has ensured that we have the most accurate and versatile CNC camshaft grinding facility in Europe. We are the only UK manufacturer grinding camshafts on bespoke CNC machines, designed solely for high performance cam lobe grinding. We have invested in dedicated cam lobe technology rather than CNC orbital ...

I just got a "Customer Satisfaction Program" letter from GM stating that GM's 3.6 liter V6 (the engine used in the Camaro, Saturn Outlook, LaCrosse, Cadillac CTS, and several other cars) is showing premature wear of the timing chain. A quick check of the web turns up that many who own this engine are experiencing troubles all the way up to the engine fragging. …

Optimizing a camshaft lobe grinding cycle has traditionally been based less on science and more on educated guesswork and numerous test grinds. Now, computer thermal modeling software can predict areas where lobe burning is likely to occur, in order to determine the fastest possible work speed that won't thermally damage lobes and greatly ...

The CNC cam grinding contour accuracy is influenced by the complexity of the cam profile and periodic disturbance caused by end effect and friction of the grinding system.
Squeaking or Grinding Noise. One of the most common symptoms of a failing belt tensioner is unusual noise coming from either the tensioner or the drive belts. If the drive belt noise resembles a squeal or a squeak, it is possible that the belt tensioner is loose. This is especially the case when starting the engine first thing in the morning.
Keywords: NC cam grinding, contour accuracy, repetitive learning control (RLC), cross-coupled controller (CCC), repetitive control. 1. INTRODUCTION In order to meet the high precision of the mechanical machining, the profile processing precision for CNC cam grinding is one of the important technical indexes for evaluating the cam quality.
