AUTOMATIC BAND SAW MACHINE:     

pásová pila na kov Pegas 290x290 A-CNC-LR-F

It is a highly efficient automatic hydraulically controlled band-saw with multiple material feed.  The length and number of pieces are set on the control panel. The machine selects the number of feeds and performs the necessary calculations by itself. The system allows the selection from nine different settings for quick adjustment of lengths or automatic modification of lengths when sawing several dimensions from one bar. There is an automatic and a semiautomatic mode, where all movements are controlled independently.   The machine is designed for vertical and angular cuts; angular cuts are steplessly adjustable from 0° to +60° right  and  from 0° to -45° left.
- automatic cutting cycle: only for 90 degree (0 degree) and 45 degree cuts to the right
- semiautomatic cutting cycle (without material feeding into the cut and feeder device in a very left position): for angle cutting to the right and left more than 45 degrees.
Change of angle using quick clamping handle. It is suitable for serial production and 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 band sawing machine has a sturdy design.   The machine is  constructionaly  designed in that way, so that it corresponds to extreme  exertions in productive conditions. That is why all carrying parts are made as cast-iron castings (solidity, damping of  vibrations and stops).  Parts of arm, vice and turn table is cust iron. 
• The arm of the machine is made of cust iron and it is designed to ensure the strenght and the precision of the cut.  Arm is 25 grades sloped, it increases the lifetime of  blade. Arm is placed in adjustable bearings.
• The cleaning brush for a perferct cleaning of the blade.
• The vice is made of cast iron and the jaws allow a safe grip. The hydraulically controlled vice with short travel is situated in an adjustable dovetail groove and is equipped by a quick clamping of material and quick clamping for side moving of vice. The adjustment is manual with a wheel and trapeze thread. Speedy jaw adjustment is achieved by means of a lever, spring and trapeze half-nut. The vice jaw travels left-right with regard the angular cut; it is secured by a crank.
• The feeding vice is driven by the hydraulic cylinder on two grinded bars by teflon cases. The feeder moves the material to be cut to the main vice according to the set lenght that was adjusted by the operator in the controlling panel.  The position of the feeder is indicated by electromagnetic sensor and measuring magnetic tape. There is a floating seating of the feeding vice in the feeder, it means that the feeding vice moves in perpendicular  sense regarding the feeding sense. The firm jaw of the feeding vice copies the possible roughness of feeded material and the wearing of mechanical parts of the feeder is eliminated.  For a perfect placing of a feeder , feeder moves to end positions by a slow velocity
• A turntable gives a big place for supportion of material and its perfect clamping. The turning table has autoarresting every 15 grades ( the groove with the spring ) General angles are adjusted by the nonius. It is possible to equip the machine by digital indication of the angle for a wish. 
• Leading of blade in hard-metal plates. An electro-mechanical device for tension control and a limit switch protect the saw-band from insufficient tension and maintain perfect cutting conditions at all times.The saw-band is equipped by a guard, which protects the operator from millings and cutting emulsion.  
• Drive of machine is solved by worm gear box with maintenanceless oil filling. Three-phases electromotor  with double winding, with  a frequency converter  for a fluent regulation of the blade speed from 20 to 100 m/min. Sturdy flange with shaft. Termoprotection of engine.
• Cooling system for emulsion with liquid distribution to blade guides. 
• Robust base with a tank for chips.
• Indication of  blade tightening and opening of the cover
• Controlling 24 V
• The main switch is located on the front door. The motor allows stepless speed variation and is equipped with a safety button, which stops the saw, and another two buttons for turning it on. There is also a feed regulator and buttons, which control the various available movements necessary for managing the “SAW MICRO” tool.
• Maschine is equipped by hydraulic system that manipulates all functions of that maschine. It presses the arm to cut, pulls up the arm, opens and closes vices, moving of feeder.

Basic equipment of machine:

• slide of cut pieces,
• blade,
• set of tools,
• manual instructions.

Operating cycle: The machine automatically grips the material in the main vice and the feeder moves into a position determined by the processor (i.e. the required length of the cut and a constant added length); the feeder-vice’s jaw stays open. The arm moves into the cut; after cutting the material, it moves into the upper position. The feeder moves by the constant added length (exactly to a position determined by the processor) and the feeder jaw grips the material. The vice is released; the feeder moves the material into the zero position (by the required length). The main vice grips, the feeder-vice is released and the entire cycle is repeated.The operator only removes the sawn material.
