TWO-COLUMN BAND SAW MACHINES FOR VERTICAL CUTS:     

510x510 HERKULES X

A highly productive semiautomatic, hydraulically manipulated two column band saw machine.
If your demands for cutting material are higher than blade with hight 41mm can assure ( 500x500 HERKULES  X),  there is our offer suitable for cutting of the most problematic materials. As the standart model, also this machine has a very rugged construction, the arm is 25 deg. sloped. These characteristics together with the more poweflull planet drive and with the blade of 54 mm hight ensure the maximum possible efficiency.
X version in the basic solution offers 64-bits control system with posibilities of  automatic regulation of the arm movement towards the cut that  depends on cut resistance of the material, electronic setting of  upper and down position of the arm, on display you can see cutting speed. The control system is prepared for comunication with other external accesories.
The machine is designed for vertical  cuts.
It is suitable for serial production in industrial premises. Thank to its robust construction enables to cut wide range of materials including stainless stells and tool steels both profiles and full materials.  

Construction:

• The machine is  constructionaly  designed in that way, so that it corresponds to extreme  exertions in productive conditions.
• A frame of this machine is made from cart iron and is leaded in two columns with linear bearings. Tough frame of machine with columns situated as near the clamping vice as possible minimizes vibrations and enables max. cutting performance.
• An arm is a rugged weldment and it is designed so that a toughtness and a precision of cut was secured.  Arm moves on  two columns by a help of  a four row linear leading with a high loading capacity.  Arm movement by a help of 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.
• Arm of machine has a an automatic sensor for a measuring of a position over material  and there is also an end stop for setting a down position.
• The vice uses the advanced construction with the long stroke hydraulic cylinder and the jaw situated on the linear leading.  Main vice with divided jaw that clamps the material in front of as well as behind the cut . The optimalization of the chip movement through the firm jaw directly to the chip extractor.
• Machine has hydraulically manipulated band tension. Electro-hydraulical equipement of a blade tension with an end switch ensures a constant tension and enables to keep ideal cut conditions.  
• Adjustable quides with hardmetal plates and upper blade leading  by a harden ring on a needle bearing.
• A giude is connected to a jaw of vice so that to achieve the minimum distance of the guide and material.
• 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 circumferential blade speed  by a frequency converter for a fluent change of blade speed. Attention: Drive with planet gearbox coresponds with drive with worm grearbox and engine of cca double multiple power.
• Cooling system for emulsion, leaded to the quides of the blade and by LocLine system directly to the cut groove.
• Robust base with a tank for chips and with a worm chip extraktor.
• Indication of  blade tightening and opening of the cover.
• Control terminal with a microprocessor, control 24V.
• The machine is equipped by the controlling MAHLER terminal, which controls the cut of the machine in two basic regimes : BIMETAL and CARBIDE.
• BIMETAL regime is suitable for optimalization of the cutting feed when cutting profiles by bimetal blades. The cutting feed is realized by PEGAS ARP system which automatically regulates cutting feed depending on the resistance of the material. The cutting feed is higher if the blade cuts sides of the prifile. As the blades reaches the full material, the system reduces the cutting feed automatically so that teeth gap of the blade would not be filled.
• CARBIDE regime is suitable for cutting of full bars by bimetal or carbide blades.  The controlling system regulates the cutting feed automatically ( 75% feed) at the beginning of the cut. The aim is to eliminate vibrations and the load of the blade teeth at the beginning of the cut. The cutting feed is constant during the cut, 15mm before the end of the cut the systems reduces the cutting feed automatically. Higher bladelife is achieved. Controlling system in CARBIDE regime uses the regulation of the cutting feed during excessive load of the blade (systems reads the load of the blade drive in Ampers). The regualtion is not active, it serves as a fuse if the blade is not worn out. The controlling system reduces the cutting feed to one half and finishes the cut.  
• The regulation of the cutting feed is realized by a hydraulic valve controlled by servoengine. Thanks to this a very precise cut is achieved. The operator inserts the desired cutting feed (mm/min)  into the programm  and the machine sets this feed very exactly. This way of control depends on the temperature (viscosity ) of hydraulic oil. 
• A controlling systém of machine represents a working states as circumferential blade speed, speed of arm movement to cut and a state of single working movements. A part of a system are also inputs and outputs for connection of an abovestandard accessories.
• Working movements are regulated by hydraulic system. There are regulation valves for setting a vice pressure in hydraulic systém.

Basic equipment:

• chip extractor
• light above the working place
• frequency converter
• blade
• set of tools
• manual instructions

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 up position and vices open automatically. The only task for operator is to manipulate with material
