CHIPREMOVAL(Continued…)
Chipconveyor
1. During operation, metal chips and used coolant
drop directly into a sloped trough, or flow into it
fromthemachine’srun‐offsurfaces.Coolantthen
flows down the trough and through a filtering
screenbeforereturningtothereservoir.
2. Thechipconveyormotoroperatessimultaneously
with the hydraulic pump motor. The conveyor
augerrotatesslowlyatthebottomofthetrough.
It’smovementcarriesmetalchipstotheopeningat
themachine’srightsidewherechipsemptyintoa
customersuppliedcontainer.
3. Aneedlevalvelocatedbelowtheaugerallowsthe
chipaugermotortobeadjustedforfasterorslower
operation.

NESTINGFIXTURE

1. This feature is designed for high‐production,
multiplesawingofstackedbars,roundsandtubing.
2. Verticalnestingclampcylindersaremountedtothe
machine’s fixed and index vises. The cylinders
operate simultaneously with the regular vise
clampingcylinders.
3. Visecapacitydependsonthemachinemodel.
Thehydraulicoperatednestingfixturecanalso
beusedwiththevariablevisepressurecontrol.

Stackingstock

1. Correct stock nesting is essential for proper
clamping of the vises and nesting fixture. It is
important that nesting vise clamping pressure be
transmittedtoeverystackedpiece.Sometimesthis
can be more easily accomplished by manually
joggingthestack.
2. Properstackingofroundstockisimportantbecause
saw band breakage may occur if round nested
piecessliporspinduringsawing.
3. There are two (2) workable round stock stacking
methods,eitherinequalrows(4x4x4)ornested
rows(4x3x4).Thefirstprovidesthebestsawing
results,althoughthesecondmethodcanbeused(if
the material is not stacked too high) and offers
betterclampingwhenmaterialhassmalldiameter
differences.
4. Pieces should be stacked as closely together as
possible. Metal chips lodged in the open spaces
betweenindividualpieces willaffectcuttingaccu‐
racy.
Viseadjustment

Nestingfixtureviseadjustments.
1. Stack stockto be cutbetween the machine’s vise
jaws.Then:(a)openthefixedandrearvises;(b)bolt
thesupportingbartightlytothefixedvisejaws,but
looseonthemovablejaws.
2. Loosenthescrewoneachsideoftheclampbars
and position the clamp bars to fit the size of the
nestedstock.Thenadjusttheindextable’svertical
guide rollers so the stock will be guided correctly
towardthesawband.
3. The indexing vise has two positions to place the
nestingfixture.
 PositionAistheforwardpositionontheindex
vise.
 Position B is the rear position of the nesting
fixture.Seethechartbelow.
4. Theremnantwillchangedependingontheposition
ofthenestingfixture.Seethechartbelow:
