BAND SAW MACHINES

Semiautomatic machine with hydraulic manipulation.
The machine is designed for cutting of material in vertical and angle cuts, angle cuts are possible to set fluently from 0 to 60 grades to the right and from 0 to 45 grades to the left.
It is suitable for piece production and small series production. Thanks to its robust construction it enables cutting of wide range of profiles and full materials. 

Control systém:

• The machine is equipped with a control system PEGAS A2 relay logic
• Button control

Construction:

• The machine is constructionaly designed in that way, so that it corresponds to standard exertions in productive conditions. That is why all carrying parts are made as cast-iron castings (solidity, absorbtion 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 power and the precision of the cut. Arm is 25 grades sloped, it increases the lifetime of blade.
• Working positions of the arm are controlled by the cam and microswitches of the upper and down position of the arm. In the end position microswitch is on, arm goes to selected upper position.
• The arm rotated by a shaft (joint) which is support by adjustableconical bearings
• The vice is made from cast iron. Jaws ensure safe clamping of the material.
• The hydraulically operating vice with short travel is placed in an adjustable dovetail groove.
• Moving jaw of the vice is manual with a wheel and trapeze thread.
• Basic part of the vice moves according to the direction of the angle cut setting, fixation is made by the handle.
• Turn table is cust iron.
• Manuall turning of the table for angle cuts, angle fixation using quick clamping lever.
• General angles are adjusted by the nonius. 

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 moving band guide is adjustable. Manual adjustment and fixing of the guide beams.
• Guide holder moves in adjustabled dovetail groof.
• The saw-band is equipped with a guard, which protects the operator from millings and cutting emulsion.
• Mechanic tightening of the blade.
• Automatic indication of blade tension.
• A passive driven cleaning brush for perfect cleaning and function of blade.
• Drive of machine is solved by worm gear box with pernament oil filling. Three phase engine with double winding, two cutting speeds. Termoprotection of engine.
• The cooling system distributes cutting emulsion to the band guides.
• Base with a tank for chips.
• Indication of blade tightening and opening of the cover.
• Controlling 24 V.

Basic equipment of machine: 

• Band saw blade.
• Set of spanners for common service.
• Manual instructions in eletronic form (CD).

Operating cycle: 
After manual adjustment of the jaws and the arm’s operational positions the operator starts the cycle with a switch on the control panel. The hydraulic cylinder of the vice grips the material and the saw starts working. The cutting speed of the arm is controlled by a throttle valve. After finishing the cutting, the arm reaches its top operational position and the band drive stops. The vice opens and the operator can handle the material.The control system monitors correct tension of the band and correct position of the band guard.
