Multi disc assemble

 

With a long and reinforced shaft, you can mount 3 or 4 discs, depending of the diameter and main power. 

Multi disc on bridge

To increase the cutting capacity over set distances, you can mount multiple saws on the same body, which will allow an entire axis to insert the discs. These will be powered by a main engine with belt system to transmit the correct rotations. This system can be mounted on double bridge, depending on the intention. The start on 125 Hp / 90 Kw or up to 220 Hp /160 Kw, depending of discs quantity.

Can Set the Displacement on Lateral’s Until 787.1/2 in / 20 meters

Side pillars are a component of extremely important equipment. An anti-resonance system was developed in these. As a way of eliminating micro vibrations caused by tools, they release a chatter that alters precision parameters as well as measuring the incidence of small marks on the material. On side of the electrical panel we put a constant coverage monitoring in linear bearing, which applies on a support surface. This is a large size to receive the load caused by cutting effort. The linear bearing can move in full oil bath, without twisting maintain a constant alignment of the bridge for displacing the cutting head. 

Assembled rack on both sides with adjustment

The weight of the rails is always the same regardless of bridge stress positioning, traction and alignment. With an oversized construction, we guarantee perfection on the side rails as well as the inner rails. All adjustable in positioning and fixed by iron bolts, the rails move from bottom to top of the gear, machining at once, ensuring perfect alignment of parts for a long time.

Stainless iron guards assemble

Can mount guards on stainless iron or bellows. We mount the bellows on small displacements, and the stainless 1/8 in. / 3 mm. in all others dimensions. On the top we screwed it and the displacement carriage has a bearing support to allow perfect movement on long distances.

Both pictures show the both sides. The interior has separate boxes to avoid the mud, for oil bath work, the side box has different dimensions on each side, on the mud side there is a system for removing resonance and on the other side the linear bearing guide for providing constant parallelism.

The conception of displacement cars on the rails is removable on assemble

We started using linear displacement bearing guides in 1993. Displacement systems have been developed and refined to increase the power of the cutting saw. The production is and to keeping equipment and finish quality.

Experience and knowledge enable us to ensure that this mechanism is the best option for exploring the equipment in all configurations with cutting benefits. 

All equipments are total assembled on factory and subject into an exhausting test control

 

Small parameters are adjusted in the assembly process, parts are deposited in a transport box, plastics to cover the motors. 

Machined surfaces on every alignment parts and support

Working on oversized displacement linear bearing guide with two bearings allows the perfection in all positions and increases the displacement velocity. There are two separate boxes, one can work with oil bath and the other removes the projected mud.

Standard And Tested Components Offers Reliability

The Hercules series adopts the principle of using common parts by changing their sizes by gammas. 

Standard Parts In:

Working tables

The intention is to indicate that the parts and components produced starting in a project were subjected to intensive tests over 50 thousand hours. In the Hercules series they are used according to a manufacturing plan, from individual design of the pieces to their join assembly, with an accessory or component that will be combined with other to get a reliable and cost-effective equipment, easy to operate and maintain, and usable to its full capacity either in production or in its profit.

Cutting heads

All the components are designed to be interchangeable between the Hercules Series. Is this the concept that we intend to presentdeveloped, tested, interchangeable, capable of receiving various upgrades, potential for expansion either in power, and that allowing the accessory exchange.

Measure system with independent counting


Based on the concept of making full use of head swapping equipment for multitasking, on the same bridge can be mounted more than one ram model. It is possible with two side supports, with one of two powertrain systems, with two transmission systems or with one of two control systems, but always with the highest quality products.

Features

-Automatic Travel Inversion System
When activated, it does an inversion everytime it detects there is no more stone to be cut. This function overrides other commands, i.e. it ignores other cuts programmed in the console and/or travels later set by the control panel. This function has depth parameters that disable the operation (necessary for the first cuts due to the irregular stones surface), inversion timer (necessary due to the irregular sides of the stones) and offset current (necessary for situations where there is saw cut capacity variations and stone hardness). This function enables to significantly decrease the time it takes to cut a stone.

– Saw opening system and progressive unlocking
These 2 functions are simultaneously activated. The first function consists in an automatic decrease of the passages should there be a higher consumption value different from the one set by the operator (it depends on the saw hardness and characteristics). Decreasing the passages will allow the saw to open and increase its performance. After the machine detects a decrease in the consumption values (because the saw is already opened), the function will automatically reset the passage to the value initially set by the operator. The consumption value from which the machine starts to increase passages also depends on a parameter set in the console. This function can also be used for decreasing equipment cutting time, i.e, it allows for the operator to programe passages slightly above the initially set values, due to the equipment later automatically setting the passage according to the programmed current control value.
The second function consists in a deceleration of the cut in cases of extreme consumption (parameter set by the operator) due to overcurrent caused by blockage/jamming of the saw, which sometimes occur in the end of the cut or because the stone has areas that are significantly harder. After this happens, the machine starts to slowly and gradually accelerate until it hits the previously set speed. The deactivation of this slow acceleration process can be done by enabling/disabling the function or by simply changing the speed knob position. Decreasing speed will also reduce the chance of the machine stops due to overcurrent, avoiding any unnecessary interruption of the production that can happen in the absence of the operator, but it is particularly helpful during nighttime production. By safety reasons, in case there is an extreme consumption, the machine automatically deactivates the inversion function.

-Travel stop pre-detection system and error due to encoder malfunction/error.
The equipment is continuing monitoring its position. By checking that the bed is closer to the supports, it starts to decrease speed before stopping completely by activation of the travel stop sensors. This function allows greater speed in the cutting area and an increase in the lifespan of the equipment, as it makes it unnecessary to decelerate on short ramps (sudden stops). By monitoring impulse counting it is possible to avoid collision due to error or encoder malfunction.

-Automatic Function/Single Cut
The equipment allows doing a single cut by setting dimensions to “Zero” or through a dedicated page.

-Measure displacement function
Allows moving the bridge to its initial cut position.

-Saw torsion prevention system
To avoid torsions in the saw caused by higher passages in the first cuts, the operator has the option to programe lower passages until the machine hits a certain cutting depth.

– Monitorings
– Calculations of the cutting area by stone and total accumulated by saw diameter
– Cutting time by stone and cutting time total
– Cutting engine power consumption through an analogue meter and virtual meter (console)
– Speeds monitoring in m/min (meters per minute)
– Quota/axle position monitoring in mm (millimeters)
– RPM monitoring (Rotations per minute)

– Programming speeds and saw diameters
The operator will be able to select the rpms of a certain saw through a simple and intuitive selection out of a pre-programmed diameter and saw speed chart.

– Cycle programming options
The operator can choose a cycle where priority is given to the axis cut or vertical axis during inversion (Z after Y or Y after Z).
The operator can set different passage values for different cutting directions.

– Recovery in case of power failure
The equipment memorizes the programmed cut in case of a power failure.

– Change of the cut travel using the control panel
The equipment allows increasing or decreasing the cut travel set in the console, by memorizing the beginning and the end of the cut.

-Anti-collision protection system
By activating the protection bar the equipment does a return movement and positions itself for the next cut. This allows the equipment to continue with the programmed cuts, avoiding any unnecessary interruption of the production in the absence of the operator, and is particularly helpful during night-time production.

-Alarm and protection systems with memory
The equipment has 23 safety alarms. It is also possible to check the Date and Time of the Alarm on a console dedicated page.

– “Normally Closed Circuit” sensors
This operating logic allows monitoring and activating the alarm in case of error or interruption of the electric sensor signal.

– SMS Alert System (optional)
The equipment can also include an sms sending system to any mobile phone, showing a total of 7 states (Alarms and Equipment Alerts).

– Technological Update
All of the characteristics and functionalities are subject to change whenever Minorca considers being relevant to upgrade the equipment.
