Features
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°.
Figure 1
Miter Position Lock
The miter position lock sec ures t he mi ter cu tti ng
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 vis e handles .
Blade Lock
The blade lock secures the arbor from rotation
when attempting to change blades. The blade
lock is pushed in when changing bl ades.
The blade lock is not spring
loaded and must be pulled out after the blade
has been replaced and before operating the
machine.
Controls
Mist Coolant System
The mist coolant system sprays a coolant mist
onto the saw blade duri ng the cutting operati on,
cooling it and the work piece being cut. Air is
supplied from a compressor to the air intake
valve (A) located near the bottom of the cabinet
on the left side. W hen the head is moved off of
the top limit switch (Figure 2) when beginning a
cut, the pneumatic switch (B) is activated,
allowing air t o flow through t he air tube (C) and
into the orifice (not shown), causing coolant to
be drawn through the coolant tube (D). The
pneumatic valve (E) adjusts the amount of
airflow. Air and coolant is mixed in the orifice
and sprayed onto the saw blade.
Use a water-soluble synthetic coolant with this
mist coolant system. The ratio should be
between 7:1 to 10:1. Coolant should be changed
regularly. Some r ecommended brands are DoAll
and Lenox. These coolant s are available at your
local industrial distributor.
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
or Low. Then depr ess the tr igger handle to start.
Trigger Handle
The trigger handle (Figure 1) is located on the
operating lever used to rai se and lower the saw.
It contains a micro-switch, which is activated
when the operator depres se s the r un trigger.

Blades
When using the J-CK350 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 Characteri st ics
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).
Deter m ining 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 di scs with a coarse toot h
pitch, while small cross-sections require blades
with finer teeth. This
is because when
cutting walls of small
cross-section (1–7
mm) profiles, it is
important that the
number of teeth
actually making the
cut should not be too
small, ot herwise the eff ect obtained will be one
of tearing rather than of chip r emoval, leading t o
a large incr ease in sheari ng stress. O n the ot her
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 wall s of the workpieces,
resulting in poor cutting (same situati on with soft
materials), greater shearing stress and hence
breakage of the bl ade.
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
2
feeding speed, in cm
/min, are limited by the
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
2
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
break-in p eriod, du ring which time abou t half
the normal feeding sp eed shoul d be used.
Coolant
The cooling fluid mist 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).
Types of Blades
The blades fitted to the J-CK350 have
dimensions 350 x 32 x 3.4 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 their particular
use:
Table 1
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)
12
Teeth Shape
”C” TYPE SHARPENING (HZ)
Coarse toothing with roughing tooth raked on
both sides and non--raked finishing t ooth – The
roughing tooth is about 0.3 mm higher.
Coarse toothing with roughing tooth and
finishing toot h – Used in saws with pit ch greater
than or equal to 5 mm for cutting ferrous and
non-ferrous m ateri als with soli d or solid-profiled
sections.
Figure 19
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 16
”BW” TYPE SHARPENING DIN 1838--UNI 4014
Coarse toothing with teeth alternately raked to
the right and left – Toothing generally used on
cutting-off m achines f or cutti ng f errous and al l oy
materials with tubular and profiled secti ons.
Figure 17
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 18
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 incr eases,
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.
Figure 20
The J-CK350 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
resistan t sectio n .
Figure 21
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.
Material too hard
Disc not worn--in correctly
Teeth breaking
Rapid t ooth wear
Broken blade
Disc with excessively fine
tooth pitch
New blade inserted in a
partially completed cut
Work piece not clamped firmly
in place
Feed speed too slow
Cutting pressure too high Reduce cutting pressure.
Blade speed too high
Insufficient coolant
Incorrect fluid concentration Check and use the correct concentration.
Material defective
Feed speed too high Reduce blade speed.
Teeth in contact with material
before starting the cut
Insufficient coolant
Check the cutting speed, feed speed and air pressure
param eters and the typ e of bl ade you are us ing.
With a new blade it is necessary to start cutting at half
feeding speed. After the wearin g--i n period (a cutti ng
surface of about 300 cm2 for hard materials and about
1000 cm
speeds can be brought up to normal values
The s warf wedges into th e bottom of t he teeth causing
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:
increas e feed s peed.
The teeth sli de over the m aterial without c utti ng it:
reduce t he bl ade speed.
Check the coolant level and clean coolant lines and
nozzles.
The mat er ials may present altered zones either on the
surface, such as oxides or sand, or in section, such as
under-cooled inclusions. These zones, which are
much har der than t he bla de, ca use the teeth to break :
discard or clean these materials.
Always check the position of the blade before starting
a new job.
Check the coolant level and clean coolant lines and
nozzles.

Check: the phases; the cables; the plug; the socket.
Also check that the motor connections are in place.
Chec k th at the voltages are pr esent both on th e input
and output. Otherwise replace.
Chec k th at the phases in i t are present both on t he
input and output, that it is not jammed, that it closes
when powered and that it is not causing short circuits.
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 burned out, that it turns freely
and that there is no moisture in the connection
terminal board box. The winding can be rewound or
replaced.
