conventional methods, the manufacturing of Hydraulic
cylinder tube used in the construction industry equipments
like JCB, dumpers, excavators are done with machining
processes like turning, honing and grinding process.
Honing, which is the final process in manufacturing
of tube Inner diameter, is a very slow process , tedious
, low productive in nature. High volume manufacturing
of cylinders in this process is not an acceptable solution.
to high volume production of cylinder tubes, a proven
process involving metal cutting and metal forming is
developed, known as SKIVING AND ROLLER BURNISHING Operation.
The advantage in this process is, the removal of stock
to the complete size of the bore, leaving around 30-40
micron stock in the ID of the tube. This stock is removed
by Roller burnishing operation which is a metal forming
process, very high cutting parameters can be achieved,
resulting in very low cycle time and thereby high productivity.
The specially developed tool is having a capability
to do the above operations in one pass. The special
purpose machine developed for this application indigenously
is a very good subsititute for an imported machine which
