JSW Steel
The Problem - When the grinder or lathe goes down, Jindal United Steel Corporation, a division of JSW,
must act quickly to avoid excessive downtime in the production area. Prior to engaging PRG, the mill was forced
to use a distant supplier who provided a service that barely met mill standards – causing production delays
and occasionally even the need to stop the production process.

Kellogg's
The Problem - For several years, Kellogg's has commissioned PRG to grind a variety of rolls. Over the July
4th holiday, the Lancaster plant faced a unique emergency. An anvil roll was producing inconsistent sheets which
put the process equipment at risk of severe damage and, subsequently, produced an inferior product. Internal
engineers suspected that the roll was outof-round, but they had no concrete proof. Additionally, the plant did
not have any drawings for this one-of-a-kind roll, making matters more complicated for determining a clear
solution.

The Problem - When the lone roll grinder at Lone Star Steel Company went down unexpectedly, there was really

that call was little more than a holler.

NGC Industries
The Problem - Heavily used calender and wire return rolls showed wear bands shortly after regrinding —
costing NGC a substantial amount of money in repeated regrinds, downtime and product quality. Two years ago,
when Production Manager Robert Hickox discovered that NGC's supplier was outsourcing his rolls, he decided to
work directly with PRG.

Steel and Pipe Company
The Problem - Steel and Pipe Supply Company has an excellent reputation for on-time delivery. Its multiple
facilities, as well as unmatched size and vast inventory, often attract the largest and most demanding
customers. In order to supply this demand, Steel and Pipe depends on its temper mill rolls to run effectively
and efficiently – every roll must be ground to the tightest tolerances to yield the best quality products.

Cate
The Problem - The plant recently purchased two spun cast nylon rolls with parabolic crowns. The maintenance
manager installed the rolls and ran them for 10 days "to run them in" — but was unsuccessful. Furthermore,
the rolls had a crown, but it was not the correct parabolic crown. The nip impressions showed the rolls touching
in the center and at the ends. Additionally, one of the roll's bearing seats was delivered to the plant with a
tag that read "Bad Journal."

Wausau Coated Products
The Problem - Wausau's rolls require extremely tight tolerances to withstand elevated temperatures of
350° Fahrenheit. Under these conditions, the typical roll requires replacement after only six months. As a
result, excessive downtime affected the mill's productivity and profitability.

UPM Blandin
The Problem - In 1989, Blandin started up their #6 paper machine line with two modern super calenders.
Over time, barring created a wear pattern, leaving an impression on the finished sheets. At one point, the mill
had to change chilled iron rolls every six weeks. The resulting downtime greatly affected productivity.
