Landis crank shaft grinding machine

AI Thread Summary
The discussion revolves around a problem with the Landis LT2X1400 crankshaft grinding machine, where a helical line appears on the crankshaft surface, only visible when rubbed with abrasive paper. Users suggest that this issue may stem from progressive wear of machine components. It is recommended to contact Cinetic Landis directly for expert advice, as they likely have experience with similar problems. Attempts to resolve the issue have been unsuccessful so far. Seeking professional assistance is emphasized as the best course of action.

Engineering news on Phys.org
We got a very knotty problem recently. Machine model is LT2X1400. An unobvious line apear on the surface of crankshaft(M3400). It can not be observed unless use abrasive paper to rub the facade. The line is helical and about 1/3 of width from LH side wall.(head of shaft is at left hand side.)  The programs have alway been not changed.
We have tried many methods to solve this problem，but there was no reaction. Do you have some suggestions？
 
Cinetic Landis LT2-1400
A symptom like that is probably due to progressive wear of some machine component.
The quickest way to resolve the matter is to contact Cinetic directly for advice.
They have almost certainly encountered the problem before.
If they have not seen it before, they should be very interested in identifying the cause.
 
Thank you!

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
