Welcome to the Poling Group


A	Strip machine down to bare frame, then sandblast, remove all superfluous metal parts, fill and grind smooth all holes, and repaint. view step
B	TUNCO Mfg. to recondition and recoat the loadwheel. Install new Lebow 2000# loadcells.
C	Remove, inspect, and rebuild or replace all motors in excess of 2 horsepower. Approved commercial rebuilder to replace all bearings and clean and treat (rewind or replace) windings. Replace all smaller motors. view step
D	Remove and inspect the spindle. If it does not have excessive runout, recondition it in its new style (hardened steel), otherwise replace it with a high carbon, cryogenically heat-treated spindle.
E	Install new main spindle Class "O" bearings and seals. Replace all other bearings.
F	Install 4-bar marker system for grade marking. Install Bijur spray bead lube system. Install Dell high point marker system. Other marking systems optionally available.
G	Replace all conveyors rollers, including sprockets and chains. Use double sprocket type rollers to reduce maintenance cost.
H	Completely rebuild grinder assemblies with new spindle bearings, hydraulic cylinders, and seals. Rebuild the grind sensor with new DCDT sensor and paddle. Replace all wear components on housings and pivots (use new Kaydon bearings, bushings, pivot pins, etc.). Install new hydraulic servo valves, heavier linkage arms, and new drive belt, and test run for 24 hours prior to shipment.
I	Rebuild single channel RRO probe assembly with new slide rails, bearings, DCDT sensor, contact sensor head, hydraulic cylinder, and valve.
J	Install new rotary union, air tank, air valves, and pressure regulator.
K	Install new belts.
L	Install new hydraulic and pneumatic hoses view step.


M	Replace all cylinders. Replace original 4" bore main cylinder with new 5" inch bore cylinder.
N	Replace original 12 or 20 GPM hydraulic unit with a new 30+ GPM pressure compensating pump and heat exchanger. This simpler, quick-acting system operates more cooly by providing high pressure immediately on an "as needed" basis, rather than deadheading. Isolate the hydraulic unit from the TUO frame and couple it by hoses to the manifold block to eliminate vibration transmission.
O	Manifold mount the hydraulic valves on the TUO frame. All manifold ports are SAE O-ring straight thread with spare pressure and tank ports for options.
P	Install new main drive reducer and timing belt.
Q	Install new ball screw and nut in carriage drive.
R	Completely rewire machine using all new components (conduit, junction boxes, wire ways, switches, indicators, etc.).
S	Repipe machine using all new components, including pipe and fittings.
T	Install new ball transfer and bearings on center mechanism. Refurbish or replace centering arms.
U	Rebuild lower chuck assembly, replace hardened washers, and regrind nose cone and adapter plates.
V	Inspect, machine, and grind carriage ways and gibs to restore to new condition.
W	Place main TUO head on horizontal boring machine to correct main spindle bores and perpendicularity of carriage slides (a significant problem area for older Akron Standard TUOs).
X	Provide controller of customer's choice. view step
Y	Perform complete system checkout and acceptance test. view step
Z	Perform preparations for shipping (as required for destination). view step
