It is a highly efficient automatic hydraulically controlled band-saw with multiple material feeding.
The band saw machine is designed for cutting in automatic cycle perpendicularly as well as angularly.
the right 0 - 60 degrees and left 0-45 degrees.
Automatic turning to angular cuts is a pert of cutting programms. A feeder movements using a ball screw A bow movements
using a ball screw. Bow turning using gear train
The band saw machine suitable for cutting of steel constructions and profiles with a longstep feeder L=1000mm (one speed of
feeder). The machine is constructed for automatic cutting of long bars, automatic turning included. Whenn the machine is
cutting Automatic programm with angle cuts and with lenghts shorter thann 500mm, the machine automatically interrupts the
automatic cycle and is waiting.
It is suitable for serial production and thanks to its robust construction enables to cut wide range of materials including stainless
steels and tool steels both profiles and full materials.

Control system:

•
Machine is equiped with programmable PLC SiEMENS SIMATIC S7-1200. Drive of band blade, movement of arm and
movement of feeder are completely controlled and drive by SIEMENS technology.
•
The coloured touch screen HMI SIEMENS TP 700 COMFORT enables easy communication with an operator. It shows
working conditions (blade speed, moving to the cut, cutting parameters etc.)
•
The machine enables to work with two modes:
SEMIAUTOMATIC CYCLE: The machine cuts the material immediatelly in a semiautomatic mode. The
o
operator uses the feeder of the machine for the manipulation with the material and for the exact feed of the
material into the cutting zone. The movement of the feeder is realized by manual buttons or by GTO function.
After starting GTO function the operator sets the position of the feeder, presses START GTO button and
feeder goes to the set position.
AUTOMATIC CYCLE: the feeder feeds the material according to the set programm. The operator sets the
o
cutting programm, machine realizes these programms, it is possible to make 200 different programms.The
part of one programm is a complete setting of the cut: blade speed, feed speed, setting of an automatic
regulation, setting of the hight of the bar to be cut, setting of the lenght of the bar, angles values and number
of pieces. The lenght and number of pieces it is possible to set in 99 lines, the machine feeds differently set
lenghts automatically. Control system shows the feasibility of the cutting by the drawings
•
Cutting feed rate is regulated by control system leaded by servomotor, ball screw and KM nut enabling very precise
feed rate. The operator sets in the program needed feed rate (mm/min) and the machine will set it up.
•
Two basic regimes of automatic system regulation (ASR): ARP a RZP.
RZP = Zone regulation. System enable to cut material in 5 zones, because of setting optional cutting feed and
o
blade speed according on blade position. Operator can choose from 2 strategy settings: DEFENSIVE setting
is approppriate for cutting very hard materials with use of carbide band blade. Cutting feed is in beginning and
in the end reduced. OFENSIVE settings supports executive cutting logs. Cutting feed and band speed are in
the beginning and in the end of cut increased. It´s about similar principle as ARP mode. Advantage is
regulation of blade speed.
ARP = System of the automatic regulation of the cutting feed rate depending on the cutting resistance of the
o
material or blunting the blade. Systém offers two basic modes of ARP: BIMETAL and CARBIDE.

•
The ergonomical control panel is mounted on the movable console and its position does not depend on the turntable
position at any angle. The control of the machine is optimalized with our control panel and the field of view is better for
an operator. The control panel is equiped with mechanical buttons and digital display of the machine control system.
Mechanical buttons controls basic saw movements (arm, vice, feeder and turntable movements) and cutting cycle start.
The safety button is present on the panel aswell. All buttons are highly resistant in anti-vandal version.

Safety module with autodiagnostics.

Construction:

•
The machine is constructionaly designed in that way, so that it corresponds to extreme exertions in productive
conditions. A robust construction of machine includes vice allows to take advantage of bimetal blades maximally.
•
The arm of the machine is robust, heavy weldment and it is designed so that a toughtness and a precision of cut was
ensured.
•
The arm moves along two columns using a four row linear leading with a high loading capacity. Arm movement using
ball screw.
•
Drive pulley and tighten pulley are both metal castings.
•
The arm uses incremental sensor for evaluation of current position above material. Upper working position of the arm is
possible to set in control system.
•
Down working position is set with adjustable mechanical stop and microswitch. Down working position of the arm is
also possible to set in the saw control system. After reaching bottom working position the arm stops in the position set
in the system.
•
Main vice with massive casting jawfor material fixing, moving along linear leading. Its moving away from the blade is
essential for left angular cuts. For perpendicular and right angles cuts is vice in its standard position. Open/close of the

BIMETAL mode is suitable for optimalization of the cutting feed when cutting profiles by bimetal
blades. The cutting feed is higher if the blade cuts sides of the profile. As the blade reaches the full
material, the system reduces the cutting feed automatically so that teeth gap of the blade would not
be filled.
CARBIDE mode is suitable for cutting of full bars. If the blade is old (blunt), loaded is the cutting feed
reduced Reaction time is slower than in mode BIMETAL.
