1. How do you carry out in-process diameter gauging of a shaft? The diameter gauging of the shaft is calculated by the CNC based on the
exact dimension of the grinding wheel. This information is obtained during
machine set up and/or after changing the grinding wheel using the mechanical
probe and it is updated after each dressing operation.
2. How can each single crank pin be centered also taking into consideration
the angular deformation of the shaft? Thanks to the CNC and to the mechanical probe it is possible to map the
shaft and to determine the exact angular position of each pin. Therefore
each crank pin can be centered also taking into consideration the
deformation which is within acceptable tolerances. This way it is possible
to regrind the shaft more times.
3. How can I center the flywheel flange in order to grind the main journals
of a crankshaft?
Very often it is necessary to center the flange with main journal to make
sure they are coaxial, this operation can easily be carried out using the
mechanical centering fixture that determines the position of the axis of the
flange.
4. During workpiece set up, is it possible to carry out angular positioning
of the crank pin without using the mechanical probe? Is a device for quick
clamping of the shafts available?
A device for quick angular positioning is available upon request and it can
be coupled with the faceplate.
5. Is it possible to grind conical cams?
Yes, by simply dressing the grinding wheel with the necessary conical shape
6. How long does the machine take to map the profile of a cam?
Instead of inputting all the parametric data with the dimensions of the
shaft it is possible to let Lynx2000 completely map the geometric size of the
shaft by using the mechanical probe. This operation prevents any human error
(possible when manually inputting data in the CNC) and depending on the type
of shaft might take between 15 and 20 minutes.
7. Are software programs for specific grinding needs available for the
customer?
Although the built-in programs allow grinding the vast majority of camshafts
and crankshaft, Berco can supply, upon request, software programs for very
specific grinding needs.
8. Compared to a traditional grinder, what kind of percentage in time saving
can you achieve?
It pretty much depends on the type of shaft and on grinding wheel used, but
for sure we talk of double digit figures
9. On average how long are the set up times?
It depends of the type of shaft, but normally just a few minutes
10. What kind of geometric accuracy can you achieve with the Lynx2000?
The accuracy of Lynx2000 is comparable with that achievable with more
expensive machines currently available in the market.
11. How is the spare part/after sales support organized?
We stock in house the most important components that can thus be shipped via
courier within a few hours and our trained technicians can easily solve on
site any problem.
