Descripción del producto

This is a block –cutting gangsaw for marble for the production of slabs at different thickness，Block of different size can be processed. They have a roughly parallelepiped shape having an overall workable length of 3.*5 meters .a workable height of 2 meters and a workable width of 2 meters.

Tools used are steel blades with sintered diamond plates

The machine is made up by a frame with parallel and tensioned blades .

The cutting motion is produced by a crank mechanism controlled by a **0 KW power electric motor through belt transmission

It is a sliding frame on slides in oil bath

The block to be cut is hoisted by a platform where the block –carrying trolley is placed.

The platform is vertically moved by four columns which also support the blade frame,

and is operated by four sets of screws and nut screws.

Through a toothed gearing ,the four screw are connected to a high downward speed gearmmotor unit and to low downward speed gearmotor unit .

TECHNICAL PARAMETER –SKJ*0

The machine is formed by :

1.Blade Frame

it is a metallic carpentry frame made up by two facing plates which are connected by two beams . The blades are fitted in both plates. The plates enable the blades to be stretched

thanks to a hydraulic sawing blade stretcher which ,if fitted ,is located on a plate on the opposite side of the fly wheel (material entrance).On the other plate the it is connected to the connecting rod small end pin .

2.Blade Frame Sliders Unit

They enable the frame to slide horizontally，They are made of cast iron with interchangeable bronze wearable parts .A particular mechanical device makes it possible

For the clearance between guides and sliders to be perfectly adjusted .

3. Lubrication System for Blade Frame Sliders

Each slider and guide are fitted in an oil tight tank.

4.Supporting Structure for the Blade Frame Sliding Guides

It is a strong metallic carpentry structure connecting each pair of lateral columns，Within

This structure two wide tanks to contain the sliders unit are obtained ,one above each column。The ground sliding guides are screwed in side these tanks，The structure also supports the frame upper inspection passageways .

5.Frame Movement Crank Mechanism

It consists of a connecting rod-crank system made in metallic carpentry and of a big cast iron flywheel designed to reduce the motion irregularity。Thanks to this crank mechanism, the flywheel rotation is converted into an alternative straight-line motion of the blade frame The connecting rod is equipped with two bearings in the small end and a large bearing in the big end.

6.Hoisting Unit

It supports the block during cutting operations and discharges the blades thrust onto the columns through the four vertical slider units，This structure is composed by :

·a strong metallic –carpentry frame;

·vertical slider unit;

The vertical slider are place at the four ends of the hoisting mechanism and slide along stainless and steel guides attached to the columns. the two opposing guides and relevant sliders are prismatic in shape while the two other guides are flat .The slider units place on the hoisting mechanism，on flywheel side ,are required load to win cutting forces and to ensure permanent contact with the columns .

7.Columns Unit

The columns support the whole handling structure of the blade frame and house the hoisting  mechanism stainless steel guides. They also house the bronze nut screws (pos

.3) which mesh in the screws(pos.4) Four oil-collecting tanks,one for each column ,collect

used oils .Four bellows provide an efficient protection for nut screws and screws.
