Paper Machine Transfer
Arms (Set)
The bores were
digitally located off of the large radius.
We overbored to trueup and cleanup, and then oversized bronze bushings
were manufactured. The mating Pedestals were recovered by spray welding and
then re-machined to their original size to match the new bushing bores.
Turbine Pedestal Base
(Set)
Base flange
dialed up true to axis of pedestal bore and warpage of base trued up. Heavy Duty steel base plates manufactured
for grouting into mill
Sunds Gearbox Housing
Recovery of
the worn bearing bores with replaceable steel sleeves, which are locked into
position and have an oil drain access slot.
The bores are setup true to the box’s mounting flanges! We believe steel sleeves of ample thickness and installation tightness are
superior to a sprayed and re-machined recovery. We have completed this project both ways on request of our
customer.
Sunds Pump Housing
Sleeve
recovery of the front and rear bores.
Housing bores are setup true to the mounting feet and flange. It is much easier and safer to setup a
workpiece like this in a boring mill rather than a lathe. Also both bores are machined in one setup
and are perfectly true!
Alstrom – Sulzer/Bingham – Worthington – Byron Jackson – Wemco – etc.
Reducer Housing
Bearing bore
recovery dialed up true to main flange area, rear bores and mounting feet
Housing Line Bore - Sleeve Recovery
Both bores re-machined in one setup which results in a perfect
alignment!
Valve Body
-offsetting errors in the bolt pattern holes because the mating flange
holes in the mill were hand layed out.
We electronically layout all large bolt patterns of this nature on our
Boring Mill using the onboard computerized Digital Location Readout. We
mechanically index smaller bolt circles on a dedicated post drill fitted with a
rotary table! These procedures save time and money when faced with future
failures and ease of mating OEM replacement components.
Modifying a sealing flange on a SS
housing
Turbine Body recovery,
Valve Body Inspection and reface
Felt Roll bearing pedestals Custom Manufactured
Kinney Strainer - Recovery of the perished lands
Last go for this one due to pitting!, but a few more miles was welcomed.
Reface of the flange areas – minimum cleanup
Bronze lands and seat
manufactured, installed and taper machined to suit cone
Thick Two Part Epoxy prime coat to the interior after
sandblasting.
Sunds TMP Refiner Bedding Housings
We internally
mill pockets within the bore to accept special bronze wear strips. This recovery provides extra wear area,
greatly extending time between re-builds.
A pocket for a steel recovery strip of the top keyslot is normally milled in and installed at the second
recovery. We manufacture the Bronze
Wear Strips and Keyslot Insert in house.
The 22” mating
Bearing Capsule is spray welded with a specially selected powder and
then precision ground to size. The Ground
Finish proves to be far superior to a turned finish in this case providing
exceptional hours between recoveries.
The long and skinny
the recovery of the bolt patterns
and surface areas of this 14’ SS workpiece was very economical.
Compressor Barrel - Recovery
Pulp Auger
CR Industrial Machine has the
capacity to get the job done.
Bud
Couplings
Internal Slotting – Precision machining of Bud Couplings for a Paper
Machine drive.
Precision Grinding of a Selectifier Shaft
There
is no better mating surface for a bushing, bearing or seal than a precision
ground finish – Customers inform us that
the hours between recoveries have significantly increased due to our grinding
of seal and bearing surfaces!
