Vitrified CBN Wheel for Camshaft Grinding
The sample application
Camshaft machining is a typical example of non-circular
grinding.
For example, in a completed turnkey project, four double
cams are ground by manual feeding.
The challenge of this operation to the grinding technique
is: up to 3 mm margin in rough machining, and only use a grinding tool for
finishing.
These seemingly contradictory requirements can be met by
a ceramic CBN grinding wheel.
Another example is the complete processing of the truck
camshaft: twelve distribution cams, six pump cams, seven journal supports,
thrust bearings and tapered shaft ends and shoulder are processed in a single
clamp.
As the inherent stress is often released during grinding
of hardened bearings and CAM grinding affects the diameter jump of the journal
support, it is not possible to process the bearings in a single process
according to the drawing.
To achieve the required quality, processing in a single
clip is usually the best approach.
PRODUCT DETAILS
Vitrified CBN grinding wheel is mainly used for grinding cam lobes of camshafts ( automobilemotorcycle, diesel, gasoline etc). Material includes cast iron, carbon steel, alloy steel, bearing steel etc. Suit for grinder like Japan Toyota, German Junker and Schaudt etc.
