Highly productive semi-automatic, hydraulically manipulated two column band saw machine. Our offer suitable for cutting of the most problematic materials. This machine has a very massive construction and the arm is 25 deg. sloped. These characteristics together with the planet drive and with the blade of 54 mm high ensure the maximum possible efficiency. The machine is designed for vertical cuts. It is suitable for serial production in industrial premises. Thanks to its robust construction enables to cut wide range of materials including stainless stells and tool steels both profiles and full materials.

Control systém:
Machine is equipped with programmable PLC SIEMENS SIMATIC S7-1200. Blade drive, bow movements and feeder movements are controled 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 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 button and feeder goes to the set position.
AUTOMATIC CYCLE: the feeder feeds the material according to the set programm. The operator sets the 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
RZP-2: cutting zones regulation. System enables to set of optimal shift speed (movement to cut) and blade speed in 5 different zones depending on blade position. An operator choose two ways of djustment: DEFENSIVE - suitable for cutting of very hard materials with carbide blades. The shift speed is slowed down on begining and ond end of cut. OFENSIVE - for productive cutting of solid round basrs. Shift speed and blade speed are raised on begining and end of the cut. It is a similar principle as ARP system. Anvantage is a possibility of blade speed regulation.
ARP = System of the automatic regulation of the cutting feed rate depending on the cutting resistance of the material or blunting the blade.
System offers two basic modes of ARP: BIMETAL and CARBIDE.
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.
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-2.
The control panel is placed in the tightening pulley cover. It is equipped with safety button, next buttons are for machine start and stop and other setting.
RTO function (rotate to position) with automatic setting of needed angle arm position.

Construction:
The machine is constructionaly designed in that way, so that it corresponds to extreme exertions in productive conditions. Massive construction enables using of carbid blades comfortably.
The arm of machine with columns situated as near the clamping vice as possible minimizes vibrations and enables max. cutting performance.
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 two hydraulic cylinders.
The robust steel pulleys sloped of 25 degrees regarding the level of the cut. Thanks to sloped arm the twist of the blade is eliminated and these is possibility to bring the blade closer to the minimal distance from the linear leading on columns. This arrangement eliminates vibrations and enables the max. cutting performance of the machine.
Upper position automatically using of incremental sensor for measuring of a position above material. Upper cutting position of frame is detected automaticaly using control system after setting of the size parameters of cutted material, or after pressing of button.
Down position using adjusting stop and microswitch. After reaching of bottom position arm goes to upper position automatically.
Vice is robust steel weldments.
Main vice with divided jaw that clamps the material in front of as well as behind the cut. The jaws allow a safe grip.The optimalization of the chip movement through the fixed jaw directly to the chip extractor.
Jaws of the main vice move on two rails of linear leading using hydraulic cylinder. One jaw is longstroke (the movement by longstroke hydraulic cylinder), one is fixed.
Regulation valves for setting a vice pressure in hydraulic system.

Basic equipment of machine:
The blade leading in guides with hardmetal plates and leading bearings and along cast iron pulleys.
There is a guide situated on the firm beam on the drive side. On the tightening side there is the guide situated on the moving beam.
The guide beams of the blade are adjustable in the whole working range. A giude moving is connected with a vice-jaw movement so that to achieve the minimum distance of the guide and material. That is why it is not neccessary to set the position manually.
The guide beam of the blade is placed in linear rails (2 linear rails and 4 bearings) with high bearing capacity.
The saw-band is equipped with a guard, which protects the operator from millings and cutting emulsion.
Machine has hydraulic band tightening.
Automatic indication of blade tension.
A cleaning brush is driven by an electroengine and ensures perfect cleaning of a blade.
There is a planet gear box drive and a three-phase electroengine, a fluent regulation of a blade speed by a frequency converter for a fluent change of blade speed.
The cooling system for emulsion, leaded to the guides of the blade and by LocLine system directly to the cut groove.
Massive base with a tank for chips and with chip extractors. Base is designed for manipulation manipulation with machine by crane.
Indication of blade tightening and opening of the cover.
Controlling 24 V.
Maschine is equipped with hydraulic system which controles all functions of that maschine. It pushes the arm to cut, pulls up the arm and opens and closes vices.

Basic equipment of machine:
Chip extractor
Lighting of workink space.
Band saw blade.
Set of spanners for common service.
Manual instructions in eletronic form (CD).

Operating cycle:
After starting the machine, vices are clamped automatically, cut is made by selected cutting speed, in the end position microswitch is on, arm goes to selected upper position and vices open automatically. The operator only handles material.
