4. Machíne descriptíon
Gravity self-feeding metal-cutting band saws a11ow for cutting of a wide range of different materíals. The arm uplift, workpiece feed,
clamping and removal ofworkpieces are carríed out manually. Awelded metal saw blade serves as the cutting too1. The saw blade is
mechanically tensioned on the blade wheel.lt is powered by an idler wheel that is powered through a work gearbox by a motor. 1n the
machiníng zone, the saw blade ìs guided through the saw blade guide heads. Outside the machining zone the saw blade is protected
by moving and fixed guards.

4.2. Oil  Damper - Saw Blade Feed to the Cut
The oil damper relief valve allows for a continuous setting of the velocity of saw blade feed towards the cut or stabilizing the saw arm in any position by mechanícal closing. The optimum value of descent can be determined very easíly by ear. The saw blade movement
must be noiseless, free from vibrations. Such a state can be achieved by reducing or increasíng the pressure force (by the velocíty of saw arm descent). The prerequisite of setting the optimum pressure is selecting the correct saw blade velocity and the optímum size of the saw blade teeth.

4.3. Mechanical Control ofthe Feed
The springs are pre-tensioned duríng the manufacture for a universal use, during whìch the arm smoothly rises and descends with a force ration ideal for most applications. Especíally when cutting sturdy full materials, it is useful to increase the blade feed usíng the
weíght of the cast iron arm. This ìs facilitated by contínuous screwíng-in of the adjusting screw and pulling down of the springs. If cutting only thin-walled sectíonal constructíon materials, it is, on the contrary, possible to pull up the springs by loosening the adjusting screw, whích leads to a smaller blade feed to the cut and, in particular, easíer arm uplíft. The adjustíng screw moves easily in the position, ín which the arm ís raised and the springs are not tensioned.

4.4. Více - Workpíece Clamping
The design of the machine allows for angular cuttìng without a need to handle the workpiece. The workpíece lies between the fixed clamping jaw and a movable clamping jaw. To set the desired cuttíng angle, swing the entire arm and the turntab!e after releasing the
arm swíng lockíng lever. Afteryou setthe desired angle (based on the angular scale), the turntable with the arm wíll lock using the arm swing locking lever. The stop screws facílítate a permanent setting of limit angles. See the F1XED ARM SW1NG STOP in Sectíon
4.4.2. In certain saw types (ARG 220 - 330 plus F), when cuttíng workpieces of the same diameter, the quíck-clamping lever allows release and subsequent workpiece clamping wíthout the need to use the handwheel. Mind the loading of the workpíece parallel with
the fıxed jaw of the vice. The quick-clamping lever and the handwheel cannot be used for corrections of wrongly placed long workpieces ín the vice, otherwise you risk a damage to the machíne. In the types marked with PLUS, upon looseníng the setting
screws, the movable part of the vice moves along the "T" groove to the left or right depending on the arm swing angle. Check whether the workpíece ís properly clamped, otherwise you risk íts ejectíon duríng cuttíng!

The prerequisíte of the correct cutting power of the machíne is the use of high-qualìty saw blades. In order to achieve a high cutting
power, it is recommended to use bimetallic saw blades. The main saw blade component is a high-quality heat treated steel wíth a high elasticity limit. Thetooth edges are high-speed steel ofthe following quality: M 42, M 51.
M 42 - a saw blade for universal use for cutting metallíc and non-ferrous materials wíthín the whole range of quality classes up to the
45 HRC hardness. The saw blade ìs suitable for cutting full materials ofall cross-sections and diameters, profıles, pipes and bundles.
M 51 - wìth reference to the M 42 saw blade, the M51 is designed first of all for cutting steel up to 50 HRC, steel of hígher strength
classes, acid-resistant and staínless steels. Futhermore, for cutting níckel, titan alloys and special grade of bronze.
Carbíde - high cuttíng power as compared to bimetallic saw blades. Suítable for cutting of steel, non-ferrous metals, materíal with hígh content of chrome, nickel, titan, stainless steel and face-hardened materials up to 62 HRC. The saw blades can be used for all materials including stainless steel, tool steel, non-ferrous metals, cast íron, plastícs and fibreboards. Characterístics of these saw blades include a high thermal conductivity, high wear and tear resístance and thus longer lífe, highercutting speed,less frequent saw
blade replacements and better productivity as compared wíth carbon steel saw blades.
Design: M 42 - composítion: w2%, Mo 10%, V 1%, CO 8%, tooth hardness: 68 HRC. For cutting of materials up to 45 HRC
Design: M 51 - composition:w 10%, Mo 4%, V 3%, Co 10%, tooth hardness: 69 HRC. For cutting of materials upto 50 HRC
Design: Carbide - tooth hardness 1600 HV. For cuttíng of materíals up to 62 H RC.
In addition to standard shapes and sizes of teeth, the saw blades are also manufactured with special features, such as saw setting, tooth angle and tooth face shape, which are used particularly for cutting of specific materials. Please contact your saw blade supplier to get more information about these features.
Saw Blade Tooth Arrangement
a) Constant- tooth edge spacing always equal
b) Varíable - the tooth edge space is different, repeatíng períodícally. This modern saw blade design enables a bigger cuttíng range in one saw blade type. It is able to elimínate víbrations caused by the tooth edge touchíng the materíal and thus to achíeve a clean smooth cut and longer service life.
