CAMSHAFT GRINDING MACHINE SCHAUDT C 700 NT. Manufacturer: Schaudt; Specifications and Dimensions Main Features Cam profile based on mechanical copying of a master pattern Cycle grinding management and Wheel Dressing management is done by CNC. X and Y axes are servo motors / ball...
Improved dual-cycle camshaft grinding machine, method of operation thereof, and improved wheel feed control subassembly therefor with a grinding wheel feed driven by an electrohydraulic pulse motor regulated by open loop numerical control. Solid state machine logic regulates the initiation of open loop wheel feeding steps and controls related machine functions.
Introduction. In this text, I will try to show how I made the camshaft for the Peewee V4 in-line four-stroke engine designed by Bob Shores. I saw this method for the first time when "Uncle" Dale Detrich showed me how to make lobes and solder them to a common shaft.
Performance Motorcycle Parts Andrews Products has been providing engineered solutions to drive the design and manufacture of camshafts, pushrods, transmission gears and related parts for Harley Davidson® products since 1972, providing quality and reliability with parts made in the U.S.A. Call and use our customer support representative to assist you in picking the right components to ...
However, the boom had hit hot rodding and there was a great deal of business for the few racing camshaft manufacturers on the west coast. Their production schedules were taxed, which resulted in slow delivery. During the five month waiting period for his special camshaft, Ed decided to enter the cam grinding business.
The grinding machines of the JUCAM series grind camshafts, cam pieces and individual cams in all series production sizes. In addition to the cams, the bearings and the flat shoulders can also be ground in a single clamping set-up. The many decades of experience in grinding with CBN guarantees maximum accuracy with extremely short cycle times.
The Landis LT1 grinding machine incorporates the technology of larger machines into a smaller imprint, providing unrivaled quality and cycle time standards for today's shorter 4 and 6-cylinder camshafts as well as for short-run processing of concentric and non-concentric single- and multi-diameter shafts.
Jun 22, 2007· He'd set it up between centers and on one end was a template of the cam. A grinding wheel was set on a slide probably spring loaded to keep contact with the work. I don't remember how the mechanism went about reducing the movement from the template, as the template was many times bigger then the final cam profile. ...

Cam grinding wheels. ... Dual cycle machines, which use rough and finish with one wheel specification: special high speed vitrified wheels are normally used in this case. 2) Two separate machines are used, one for roughing and one for finishing. Standard vitrified wheels are used for roughing and resinoid wheels are used for finishing.
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.
Oct 29, 2004· 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 reduce the number of requisite test grinds.
Turns out (pun), there are lots of alternatives when it comes to making cams. Harmonic Cams formed by grinding from a much magnified master cam profile are as good as you can get, but our hobby abounds with many very successful model engine where the cam profile has …
A Model Camshaft Grinding Process : Modern Machine Shop. 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 .
May 05, 2017· I read a little of that post and some of the stuff he was saying just about blew my mind lol. He thinks he's getting more compression with less valve overlap, thinks moving the cam a tooth is a good way to change cam timing...thinks grinding on the cam is increasing lift without making the base circle smaller....there are just so many things! lol
Nov 11, 2011· A leading manufacturer of high-performance valve train components installed a twin spindle/twin-turret lathe to bring camshaft machining work in-house. Here, the company explains how it has become more effective using its multifunction lathe to produce small batches of custom racing camshafts.
In mechanically timed ignition systems, a separate cam in the distributor is geared to the engine and operates a set of breaker points that trigger a spark at the correct time in the combustion cycle. Electrical. Before the advent of solid state electronics, camshaft controllers were …
These multiple-belt cam grinding machines can grind all lobes simultaneously for cycle time reduction. Another advantage offered by these machines is in the grinding of re-entrant camlobes. Grinding of re-entry type cam profiles with grinding wheel requires that smaller diameter wheels be used.
A method of successively grinding a plurality of cams on a camshaft by performing a grinding cycle for each of the cams after each cam is brought into alignment with a grinding wheel through indexing movement in the axial direction thereof. The grinding cycle is performed with said camshaft being rotated and rocked respectively about its axis and a pivot axis parallel thereto and includes ...
