BAND SAW MACHINES

300x320 SH-LR (II.GENERATION)
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 60° right to 45° 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
• Control panel placed at the moving console for comfortable machine handling. There is equipped with a safety button, which stops the saw. There is also a feed regulator and buttons which control the various available movements.

Construction:

• The machine is constructionaly designed in that way, so that it corresponds to extreme exertions in productive conditions.
• 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.
• The arm rotated by a shaft (joint) which is support by adjustableconical bearings
• Drive pulley and tighten pulley are both metal castings.
• Upper working arm position controled by automatic stopper (DPP)
• The down working position of the arm controlled by the miscroswitch. In the end position microswitch is on, arm goes to selected upper position.
• The vice is made from cast iron. Jaws ensure safe clamping of the material.
• 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. Speedy jaw adjustment is achieved by means of a lever, spring and trapeze half-nut.
• 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. A turntable gives a big place for supportion of material and its perfect clamping.
• Manuall turning of the table for angle cuts, angle fixation using handle. The turning table has autoarresting every 15 grades ( the groove with the spring ).
• 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.
• The beam of the guide is moving in sliding leading.
• 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.
• Massive base with a tank for chips. Base is designed for manipulation manipulation with machine by pallet truck and also by any hight lift truck.
• Indication of blade tightening and opening of the cover.
• Controlling 24 V.
• Maschine is equipped with hydraulic system which ensures all functions of that maschine. It pushes the arm to cut, pulls up the arm and opens and closes vices.

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 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. Arm and vice movements after cut finish following set user parameter. The vice opens and the operator can handle the material.
