Flood Coolant System
Miter Cutting Head
The miter cutting head is the unit that cuts the
material and c onsists of a cast i ron base, blade
support unit and guard, transmission unit, and
motor. The depth of cut is set by adjusting the
depth cut stop. The miter cutting head swivels
and locks into -45º, 90º, and +45º by means of a
locking mechanism. Depressing the mechani sm
overrides the lock, permitti ng the head to adjust
to any position between -45º and +45°.
Miter Position Lock
The miter position lock secu res th e mit er cut tin g
head from movement. The miter is secured
when the lock is pushed all the way to the left
and can be positioned when the l oc k is moved to
the right.
Self-centering Vise
The self-centering vise holds the work piece in
place during c utting. The work piece is secur ed
in the vise by turning the vise handles.
The coolant pump must be
submerged before operating to prevent
damage to the pump.
Coolant is di spensed directl y onto t he saw blade
from a coolant fitting on the upper blade guard.
Coolant is provided through tubing from the
coolant pump (Figur e 2) in the mac hine base.
Adjust the coolant flow valve on coolant fitti ng to
achieve desired fl ow. When the coolant switch is
in the ON position, flow starts when the drive
motor is started. Turning off the coolant switch
stops coolant fl ow.
This coolant system can operate with either a
soluble oil base coolant or water-soluble
synthetic coolant. Coolant should be changed
regularly. Some r ecommended brands are DoAll
and Lenox. These coolants are availabl e at your
local industrial distributor.
J-FK350 Controls
The cont rol panel c onsist s of the Power (On/Off)
switch and High/Stop/Low switch, and an
integral coolant system. To operate the
machine, the Power switch must be set to on
and the High/Stop/Low swi tc h m ust be se t fo r Hi

Blade Selection
When using the J-FK350 cold saw, it is
important to sel ect the correct type of blade for
the material to be cut. Thi s section explains the
limitations and specific applications of the
different t y pes of blades.
General Characteristics:
Fine Tooth Pitch – used for thin wall materials
such as sheet steel, tubes and prof iles
Coarse Tooth Pitch – used for large crosssections – for soft materials (aluminum alloys
and soft alloys in general).
Determining Proper Tooth Pitch
Proper tooth pit c h depends on:
a) the size of the section;
b) the hardness of the m aterial;
c) wall thickness.
Solid sections call for
discs with a coarse
tooth pitch, while
small cross-sections
require blades with
finer teeth. This is
because when cutting
walls of small crosssection (1–7 mm)
profiles, it is im portant that the number of teeth
actually m aking the cut should not be too small,
otherwise the effect obtained will be one of
tearing rat her than of chip remov al, leading to a
large increase in shearing stress. On the other
hand, when cutting thick materials or solid
sections using an excessively fine tooth pitch,
the chip collects as a spiral inside the gull et, and
since fine tooth pitches have small gullets, the
accumulat ed chip will exceed the gullet capacity
and press against the walls of the workpieces,
resulting in poor cutting (same situati on with soft
materials), greater shearing stress and hence
breakage of the bl ade.
Table 1
A larger pitch should be chosen when, as a
result of the shape of the piece to be cut, the
cross-section at any given point exceeds the
average cross-sect ion given above.
Cutting and Feeding Speed
The cutting speed, in m/min, and the head
feeding speed, in cm
amount of heat generated near t he points of the
teeth. If t he head feeding speed is too hi gh, the
cut will not be straight i n either the vertic al or the
horizontal plane. As we have already said, the
cutting speed depends on the strengt h (kg/mm
and hardness (HRC) of the material and the
dimensions of the thickest section. The feeding
speed depends on the cross-section of the
material. Solid or thick-walled materials
(thickness>5mm) can therefore be cut at high
speed providi ng there is sufficient swarf rem oval
by the blade, while t hin-wall ed mat erials such as
tubes or thin profiles must be cut with a low
feeding speed.

A new blade requires a
Coolant
The cooling fluid ensures that the blade teeth
and material in the area of the cut do not
overheat. The fluid must be an excellent
lubricant so as to prev ent abrasion of the teet h
and welding of t he chips to t he teet h themselv es
(seizing).
11
Page 12
Blade Structure
For non-ferrous metals, it is common to use
circular saws wit h brazed hard m etal HM cutting
edge, consisting of a disc made of alloy tool
steel (71Cr1) on which the shape of the teeth
and the seats for the cutti ng edges are made of
Widia K10. These saws have shown excellent
wear resistance but low resistance to impact,
which is in any case a minor pr oblem with nonfe rrous materials.
Table 2
Types of Blades
Figure 14
”BW” TYPE SHARPENING DIN 1838--UNI 4014
Coarse toothing with teeth alternately raked to
the right and left.
Toothing generally used on cutti ng-off machines
for cutting ferrous and alloy materials with
tubular and profil ed sect ions.
The blades fitted to the J-FK350 have
dimensions 350 x 32 x 2.5 mm and are of HM
hard steel type sinc e the machi ne is to be used
for cutting non-ferrous materials. In addition to
the size and pitch of the teeth, however, the
blades also have different geometric
characteri stic s i n accordance with thei r partic ular
use:
tooth cutting angle – may be negative or
positive
tooth sharpening –may be BW with an
alternate raked tooth or C with a roughing tooth
raked on both sides and a non--raked finishing
tooth
tooth pi tch – the distance between the crest of
one tooth and the crest of t he next toot h (tooth
pitch = T)
Teeth Shape
”C” TYPE SHARPENING (HZ)
Coarse toothing with roughing tooth raked on
both sides and non--raked finishing tooth. The
roughing tooth is about 0.3 mm higher.
Coarse toothing with roughing tooth and
finishing tooth. Used in saws with pitch greater
than or equal to 5 mm for cutting ferrous and
non-ferrous m ateri als with soli d or solid-profiled
sections.
Figure 15
POSITIVE AND NEGATIVE CUTTING ANGLES
The cutting angle may vary from positive to
negative depending on the cutting speed, the
profile and the type of m at eri al to be cut.
Figure 16
A positive angle determines bett er penetrati on of
the tool and hence lower shear stress and
greater ease of sliding for the swarf over the
cutting edge. On the other hand, the cutting
edge has lower mechanical resistance, so as the
breaking load of the material to be cut increases,
the cutting angl e decreases from positiv e until it
becomes negativ e so as to offer a cutting edge
with a larger resistant sect ion.
12
Page 13
Figure 17
Short swarf material such as brass, bronze,
aluminum and hard cast iron require smaller
cutting angles because the swarf becomes
crushed immediately and the rake angle has
little effec t during the cutting stage.
Figure 18
The J-FK350 uses discs with positive cutting
angles for cutting solid materials and with
negative cutting angles for cutting hollow
profiles. Thi s is because, as a result of the hi gh
cutting speeds (3400 rpm), even with
non-ferrous materials the tool ”strikes” against
the wall of the profile to be cut several times,
thus requiring a cutting edge with a larger
resistant section.
Figure 19
Circular saws can also be characterized by other
parameter s such as the whine r educti on f eature,
which cuts down noise at high speeds, or
expansion, which compensates for the pushing
of chips inside the cutting edge, thus reducing
the thrust on the walls of t he material to be cut.

Troubleshooting
Troubleshooting – Blade and Cutting Problems
Problem Probable Cause Solution
Incorrect lubricant/coolant fluid Ensure proper coolant flow.
Check the cutting speed, feed speed and air pressure
parameters and the type of blade you are u sing.
With a new blade it is necessary to start cutting at half
feeding speed. After t he wear ing- - in period (a cutting
surface of about 300 cm2 for hard materials and about
1000 cm
speeds can be brought up to normal values
The s warf w edges into t he bott om of the teeth caus ing
excessive pressure on the teeth themselves
The surface of the cut may have undergone work
hardening. When starting work again, use a lower
cutting speed and head feed speed. A tooth from the
old blade may be left in the cut: check and remove
before starting work again.
Any movement of the work piece during cutting can
cause broken teeth: check the vise, jaws and clamping
pressure.
The blade runs over the material without removing it:
increase feed sp eed.

Change if any of these problems are found.
Make sure it is closed, i.e. check that the phases are
present in input and output, that it is not causing short
circuits and responds when the reset coil is closed. If it
has tripped to protect the motor, check the amperage
setting, reset, and check the motor. Change if
necessary.
Check that it has not burnt out, that it turns freely and
that there is no moisture in the connection terminal
