5.Descriptionof Individual Units-all Models
5.1.Settingof Cutting Angle
The machine design enables cutting the material in angle without material handling. The material is stable between the fixed and
moving gripping jaws. The cutting angle is set by turning the band saw head including the rotary table Y after releasing the arresting
lever Z of the table. The band saw head must be elevated while it is being turned so that the saw blade is above the bearing surface of
the vice. When the required angle has been set (acc. to angle scale), secure the rotary table with the arresting lever Z of the table.
The fixed stop serves for constant setting of the limit angles. Noanglecutting is possible with theARG220 NC Automat model.

5.2.1. Setting of Vice Clamping Force
The hydraulic unit is provided with a PRESSURE CONTROLLER which enables the setting of the required vice clamping force
between 15-35 bar depending on the workpiece type. Low pressure is used in cutting thin-walled sections so that their distortion in
clamping may be avoided. Turning the PRESSURE CONTROLLER to the left decreases the pressure; turning to the right increases
the pressure (see figure). The set pressure is displayed on the vice pressure display. If the pressure is set below 15 bar, the SAFETY
PRESSURE CONTROLLER does not switch on and the saw blade does not start.

can cause damage to cylinder sealing, prolongation of feed intervals and impact the accuracy of feed.

In order that the feed system may work accurately, there must not be any guide clearance on the moving vice gripping
jaws. Therefore, the vices must be regularly checked and adjusted.

5.2.3.Moving Vice Feed System
The standard equipment of all moving vice models is a retarding system in end positions, both when the material is moved forward
and backward.
DescriptionofCycle:
The moving vice clamps the workpiece, starting slowly to move forward (approx. 4 mm); then the induction sensor switches the
hydraulic system over to the fast feed and the last 4 mm before the end position is achieved, it again switches over to the slow
retarding speed. The same process repeats when the vice reverses. This system ensures maximum accuracy of workpiece feed,
prevents workpiece skidding, delayed actions in end positions and mechanical impacts in the entire system. The retarding system
also eliminates the weight loss of the work piece while it is gradually being cut off.
5.2.4.Setting of Feeding Speedof Moving Vice
The standard equipment of the hydraulic cylinder of the moving vice feed system in all NC Automat models is a control valve, which
enables continuous setting of the feeding speed of the moving vice.
The correct speed setting affects the speed of the cutting cycle including the accuracy of the feed. Lower speed of feed is used for
heavy, full materials, for which the maximum accuracy is required. On the contrary, faster feed can be used for sections, which are
usually longer.

5.2.5.Setting of Auxiliary Roller
The auxiliary roller moves on guide rods and serves for supporting
short (end) workpieces, which do not reach the firm roller track.
The auxiliary roller should be adjusted outside the zone of movement
of the feed vice according to its feed length.

5.2.6. HVP 250, 300 NC Pressure Device for Bundle Cutting (special outfit)
The vertical hydraulic pressure device serves for clamping the material for cutting in bundles (except for ARG 220 NCAutomat). The
correct and sufficient clamping of all material pieces in the bundle substantially influences the saw blade life. The pressure device is
adjusted to the clamping cycle of the fixed and moving vice.
The pressure plate serves for vertical clamping of the material. The pressure plate diameter is 70 mm (see figure). If a larger bearing
surface is required, install your own fixture with required dimensions on the pressure plate.

5.3.Saw Blade Guide
The Saw blade is guided in two guide heads provided with eccentrically arranged bearings, which enable the saw blade winding
more easily towards the guide on the moving wheels and the carbide guides on either side and the upper edge of the saw blade. The
right guide head is mounted on the fixed guide bar. The left guide head is on the moving guide bar, moving in the distance of 5 to 10
mm from the workpiece. The guide bars are provided with saw blade protective enclosures as far as the cutting zone. There is no
sawbladeprotective enclosure in thecuttingzone.
A timely replacement of the saw blade is necessary for achieving a good cutting power, the surface quality and the workpiece
dimensions. High consumption of electrical power, scarf cuts and rough cutting surfaces are caused by blunt saw blades. One of the
important factors affecting the quality of the cut and the life of the cutting tool is the correct and sufficient saw blade tension. The
correct saw blade guide on the moving wheels and the guide heads affects substantially the saw blade life.
5.3.1.SawBlade Replacement, Tension andSetting
The TOTAL STOP button is unlocked. Release the arresting lever of the end stroke of the band saw head so that band saw head
stroke cam for elevating the band saw head in the upper position is released nd
elevate the band saw head in the upper position (see chapter 6).When replacing a broken S
(see fig. 5.5.). Switch on the MASTER SWITCH, depress
the hydraulic unit - START button. Shut off the control valve (see chapter 5.4). Switch over the machine to MANUAL MODE a
aw blade (the saw blade limit switch is
not switched on), elevate the band saw head in the upper position by pressing the button 3 on the control unit (see chapter 6 - Manual
mode). Switch off the master switch or isolate the machine from supply and secure it against restarting. Remove the rear guard of the
band saw head. Releasing the tension grip, release the idler and thus the whole saw blade. Remove the saw blade from the moving
wheels and push it off the guide heads (see chapter 5.3.2.). Insert the new saw blade in the guide heads. Put it on the moving wheels
and tighten with the tension grip.
Tighten the tension grip so that the Belleville washers are pressed completely (no light appears) and the saw blade limit
switch switches!Inthis way, the correct saw bladetensionisachieved!
Note: These operations may only be carried out when the master switch is off and
securedagainstrestarting or when themachineisisolated from the network.
Warning: Danger of injury by the sharp saw blade teeth. Use protective gloves. Do not

Close the guard, switch on the master switch or connect the machine to the network. Switch on the hydraulic unit and set the
minimum saw blade speed. Start the saw blade by depressing the push-button Saw Blade Start so that it turns approximately once
through. Make sure that the saw blade fits correctly in the guide heads. Restart the saw blade with the Start push-button and let it turn
approximately once through. Switch off the master switch or isolate the machine from supply and secure it against restarting.
Remove the rear guard of the band saw head to make sure that the saw blade is correctly fitted in the guide heads and correctly
installed on the moving wheels (see figure). If the saw blade is not correctly installed on the moving wheels, release the tension grip
and adjust the wheel setting with the screw (see figure). Tighten the tension grip so that the Belleville washers are pressed
completely (no light appears) and the saw blade limit switch switches! Close the rear guard of the band saw head and switch
on the hydraulic unit. Make a test run of the saw blade. Switch off the master switch or isolate the machine from supply, and check the
fitting of the saw blade on the moving wheels. Repeat the whole procedure, if required. For casual checking of blade position can be
used SAW BLADE GUIDE INSPECTION HOLE. Close the rear guard of the band saw head, switch on the master switch and the
hydraulic unit. Adjust the stoke height of the band saw head (see chapter 5.5.). Carry out the first cut.
5.3.2.GuideHead Setting
The correct setting of the bearings and the carbide saw blade guides in the guide heads substantially\ influences the saw blade life
and the quality of the cut. The eccentrically arranged guide head bearings must be set in such a manner that the saw blade surface is
parallel to the carbide plate surfaces and the clearance between these plates and the saw blade is minimal.
