Arthritis of the neck orcervical osteoarthritis involves degenerative changes in the joints of the neck. These are often due to wear-and-tear of normal aging. As you grow older, the discs between the bones of the neck gradually wear down, lose lubrication, and become stiff.
Roll Surface Inspection System (RSIS) in operation The WS 1100 Monolith™ grinds back-up rolls in chocks Herkules offers a series of grinders with travelling tables that unite a number of technological benefits, such as the possibility to control the grinding process on the fly.
The roll can be reground with reference to the raceway surface of the inner ring that is tightly fitted to the roll neck. When a grinding allowance is provided for the inner ring raceway surface and ground together with the roll barrel after fitting to the roll neck, the roll run-out can be minimized. Accordingly, a four-row
That results in consistently high grinding quality on the roll. Thanks to the combination of hydrodynamic and hydrostatic spindle lubrication, Herkules achieves a minimal bearing play for both very high and very low revolutions per minute and thus a precise positioning of the wheel under changing load conditions.
Neck Pain - Neck grinding or cracking can decrease the mobility of the neck after some time. This is due to the wearing down of the cartilages surrounding the vertebrae, leading to degenerative changes characteristic of arthritis. This results in inflammation and neck pain as pressure builds up on the nerves.
Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited …
Loose fit on roll necks and helical groove in the bore. In most rolling mill applications, four-row tapered roller bearings are mounted with a loose fit on the roll neck. This enables quick roll changes. However, loose fits have the disadvantage that the inner rings turn on their seats under load.

CNC Controller – The FANUC CNC-controller provides a more automated roll grinding process where the grinding operator inputs a grinding program to performed the grinding cycle sequentially. The crown grinding is also easy to get which include base arc curve SINE curve COSINE curve CVC curve and combined arc curve.
7/3/1990· The grinding eliminates much of the runout caused by manufacturing tolerances in the roll neck and race and the expansion tolerance of the press fit, although a little runout will remain due primarily to imperfections in the grinding operation itself, for the inner race may have one or more lobes in its profile after grinding.
